Growth performance and proximate composition of Clarias gariepinus (Burchell, 1822) fingerlings fed varying inclusion levels of ripe banana (Musa Sapientum) peel

The cost of fish feed is of great concern in fish farming. The growth performance and proximate composition of Clarias gariepinus fingerlings fed varying inclusion levels of ripe banana peels as a possibility of replacing soybean as a component of the fish feed were evaluated for a period of 12 weeks. 250 C. gariepinus fingerlings were acclimated for 2 weeks and fed to satiation morning and evening. Five isocaloric and nitrogenous diets were prepared from ripe banana peel thus: 0% (Control), 25% (T25), 50% (T50), 75% (T75) and 100% (T100) inclusion levels to replace equal weights of soybean, respectively. Some growth parameters such as standard length (SL), total length (TL) and weight were determined on weekly basis. The proximate compositions of the fish in each treatment and control were determined at the end of the experiment. The data generated were subjected to one way analysis of variance and considered significant at P≤0.05. From the results; the weight, SL and TL mean values measured in the control were significantly higher than other treatments in most of the weeks of the experiment. The highest weight in the control was 52.43±10.80g while the highest amongst other treatments was 30.67±6.69g obtained in T75 at the end of the 12 weeks. The ash content, crude fibre and fat contents were mostly significantly in T75 and T100. The highest moisture content (12.88±0.74%) was also obtained in T100. The crude protein content was significantly higher in the control than other treatments with 68.69±0.35% at the end of the 12th week. The results of this research has shown that banana peel can be included up to 75% level of inclusion as possible replacement for soybean in fish meal production and therefore, capable of reducing the cost of fish production incurred by farmer. For optimal performance, the crude protein content should be improved upon by inclusion of other cheap protein sources.

Bio-control efficacy of selected indigenous nematophagous fungi against Meloidogyne enterolobii in vitro and on dry bean (Phaseolus vulgaris L.).

Dry bean (Phaseolus vulgaris L.) is an important commercialized field crop in South Africa for aiding in food security as a cheap protein source. However, it is highly susceptible to root-knot nematodes (RKN), Meloidogyne species. Use of indigenous nematophagous fungi as bio-control agents (BCA) of Meloidogyne nematodes is a promising research focus area. This is because indigenous fungal species are naturally part of the ecosystem and therefore compatible with other biological processes unlike most synthetic chemicals. The objective of the study was to identify indigenous nematophagous fungal BCA and establish their potential efficacy in reducing M. enterolobii population densities on dry bean with and without incorporation of compost. Screened indigenous fungal species included Aspergillus terreus, Talaromyces minioluteus, T. sayulitensis, Trichoderma ghanense, and T. viride. There were observed significant parasitism differences (P ≤ 0.05) among the BCA, with T. ghanense showing the highest egg parasitism (86%), followed by T. minioluteus (72%) and T. sayulitensis (70%). On the other hand, the highest J2 parasitism was observed on T. minioluteus (95%), followed by A. terreus and T. viride (63%). A similar trend was observed under in vivo conditions, with higher efficacy with compost incorporation. This provides a highly encouraging alternative and ecologically complementary Meloidogyne management in dry bean production.

Morphologic and phylogenetic investigations revealed size-divergent clades in chelae morphotypes of freshwater prawn Macrobrachium vollenhovenii Herklots (Decapoda: Palaemonidae) in a lake and river system of Southwest Nigeria

BackgroundThe freshwater prawn Macrobrachium vollenhovenii is one of the largest Macrobrachium species, a biological agent against human schistosomiasis, and a cheap protein source in riverine communities in West Africa. However, its aquaculture development for sustainable utilization is challenged by cryptic identity amidst the presence of morphotypes of unknown size and genetic relatedness. This study aimed to investigate the maximum sizes and evolutionary links of chelae morphotypes in M. vollenhovenii for precise identification and utilization in a 3 × 2 randomized block experimental design. Ninety biggest encountered samples of M. vollenhovenii chelae morphotypes—those possessing equal left and right side chelae, longer left chelae, and shorter left chelae—were obtained from fisherfolks’ catches at each of Asejire Lake and Ogun River during peak seasons (July–September) bimonthly field survey, representing EAAL, LLAL, SLAL—GAALs, and EAOR, LLOR, SLOR—GAORs. These were analyzed for differences (p < 0.05) in size-linked parameters—length (L (cm)), weight (W (g)), and condition factor (K). Specimens’ 16S rRNA nucleotide sequences were utilized to infer phylogenetic linkages, single-nucleotide polymorphism (SNP), and amino acid translations alongside NCBI references (NCBIrefseq).ResultsWeight (W) and condition factor (K), among GAALs, for SLAL and LLAL were similar; EAAL was significantly lowest; among GAORs, SLOR and LLOR were similar; and EAOR was significantly lowest. In GAALs, EAAL, LLAL, and SLAL had higher L, W, and K than counterpart GAORs. Sequences formed two polyphyletic groups: EAOR branch from EAAL, in which 100.0%EA rooted 75.0% NCBIrefseqs, forming a clade; and GAOR-SLOR and LLOR branch form GAOR-LLAL rooted SLAL, in which 100.0%LL and SL rooted KJ463387.1 (Badagry), forming another clade. SNP Locus 91 separated 100.0%GAOR from 100.0%GAAL and 100.0%NCBIrefseqs translating to valine; SNP Locus 171 separated 100.0%EA and its co-rooted NCBIrefseqs from 100.0%LL, SL, and their co-rooted NCBIrefseq, translating to glycine/glutamic acid change.ConclusionThe equal left and right side chelae and the unequal left and right side chelae specimens are, respectively, small- and robust-sized, irrespective of habitat. They are divergent size-linked clades having protein translate differences, delineable at 16S rRNA SNP Locus 171; their size variant habitat strains are delineable at SNP Locus 91. These SNP markers will be useful for precision identification and selection of the size variant chelae morph strains for sustainable utilization.

Effect of CaCO3, humic acid, and arbuscular mycorrhizal applications on soybean growth in ultisol of Sijunjung, West Sumatra

Soybean is an important source of cheap protein. However, an adequate supply of soybeans is still challenging in Indonesia. This research aimed to evaluate the morphological, physiological, and yield responses of soybeans from the application of calcium carbonate (CaCO3), humic acid, and arbuscular mycorrhizal fungi (AMF). The research was conducted from December 2022 to April 2023 at the ultisol soil of Sijunjung Regency, West Sumatra. The experiment used a split-split-plot design with three replications. The first factor was AMF and without AMF application. The second factor was humic acid and without humic acid. The third factor was doses of CaCO3 application: 0, ¼, ½, ¾, and 1 time of exchangeable Al. The results showed that CaCO3 application significantly affected root length, shoot dry weight, N-tissue content, soil pH, and exchangeable Al. The application of AMF affected the percentage of AMF colonization. The yield components did not show any significant differences among treatments. However, the yield was 24.85% higher than that written in the official description. Therefore, the application of CaCO3 or humic acid or AMF could be a potential solution to increase soybean yields in ultisol. It needs further evaluation in the field to support future farming practices. Keywords: Al-exch; calcium carbonate; N-tissue content; productivity; soil pH

Evaluation of storage stability of dietary fibre incorporated aerobically packaged spent hen meat snacks at ambient temperature

PurposeThe purpose of the study was to produce a healthier, convenient and traditional ready-to-eat (RTE) snack option with increased nutritional value, using spent hen meat, dietary fibre (DF) and simple technological methods. The product was designed to be stable without refrigeration and be easily adoptable by local self-help groups, rural women and youth and entrepreneurs in urban and semi-urban areas.Design/methodology/approachConventional binder used for making snacks, i.e. rice flour was partially replaced by different sources of antioxidant DFs, i.e. oat flour (T1 – 10%), finger millet flour (T2 – 5%) and amaranth flour (T3 –15%) to prepare spent hen snack sticks (SHSS). The snacks were then packaged in low density polyethylene (LDPE) pouches and evaluated for their storage stability at ambient temperature for a period of 35 days. Their physico-chemical, sensory and microbiological quality was evaluated at a regular interval of 7 days. The proximate composition of developed SHSS was compared to commercially available snack products (chakli/murukku – snacks without meat).FindingsThe fibre-enriched SHSS showed significant improvement in nutritive value, as they contained more fibre (p = 0.001) and protein (p = 0.029) than control SHSS. When compared to commercially available snack product SHSS showed three-fold significant increase in protein (p = 0.000) and ash content (p = 0.001) and only 11%–12% total fat as compared to 31% fat in the market-available product. The most acceptable treatment in terms of overall sensory quality and nutritional aspects was T3; however, T2 was more shelf-stable during the storage period. The study showed that fibre-enriched snacks can be stored at ambient temperature for up to 35 days without substantial loss in physico-chemical, sensory and microbial quality. Hence, substituting rice flour with DFs can lead to the development of products with better sensory attributes and improved functionality.Social implicationsThe simplicity of the product in terms of composition, machinery and low production costs makes it an easily adoptable one by small-scale entrepreneurs, especially those belonging to semi-urban areas.Originality/valueIncorporation of spent hen meat, a relatively cheap but abundant source of protein, in RTE products can serve as an effective way to alleviate protein malnutrition, whereas addition of fibre further improves the functionality of the product. The methodology can be easily taken up by small-scale entrepreneurs and create a market for snack-based functional meat products.

Aquaculture: A hidden goldmine for the rural poor—A cost–benefit analysis of fish farming for sustainable development and food security in Vihiga County, Kenya

AbstractIn Kenya, aquaculture plays a significant role in enhancing the livelihoods of rural communities by boosting the local economy and diversifying protein sources. Although Vihiga County in Western Kenya boasts considerable potential for aquaculture, it paradoxically experiences some of the highest levels of poverty and malnutrition in the country. The profitability of fish farming has also been affected by inefficiencies and poor resources, disproportionately affecting the income and nutritional value of rural poor who rely on Aquaculture as a source of cheap protein. The study was conducted in Vihiga County to assess the cost–benefit of aquaculture production, selecting 100 fish farmers through a stratified random sampling technique from five sub‐counties. A descriptive research design was employed, and data analysis was conducted using correlation and regression analysis with SPSS. Budgetary techniques were used for the cost–benefit analysis. Data presentation was by comparing the mean and standard deviation in US dollars of different pond size production. The research findings indicated that the size and type of pond do not have a significant correlation and differences in production (p‐value &gt;.05). There is a strong positive correlation between the size of the pond and the stocking density. The variable cost (VC) has a positive correlation with pond productivity meaning that an increase in VC leads to an increase in production. And is not statistically significant (p‐value = .21827, p‐value &gt;.05). Moreover, the total cost (TC) correlation is statistically significant (p‐value = .0351, p &lt; .05). Larger ponds are more profitable but require higher costs production than smaller ponds. The study concludes that pond size significantly impacts productivity, advocating for smaller ponds to achieve higher net returns with lower production costs. Major challenges include high costs of feeds, inputs, fish diseases, and post‐harvest losses. Key policy variables influencing aquaculture in Vihiga County include infrastructure, fish feed production, capital, and fisheries extension services. Adequate financial support from both National and County governments is crucial for sustainable aquaculture in alignment with Kenya's Vision 2030 and Global Sustainable Development Goals. Policymakers are urged to assist small‐scale farmers with financing, training, and market information to optimize returns on investment.

Produire des protéines

This article claims that the pursuit of protein specifically, not meat in general, is woven into the very fabric of industrial hog farming and the devalued animals at its centre. Further, this piece forces a critical lens and reclassification of the value of protein sourced from confined animal feeding operations (CAFOs), using Goodman, Sorj and Wilkinson’s (1987) concepts of substitutionism and appropriationism as a framework to unpack how hog production in Canada is structured on producing protein for mass consumption. Lastly, this article categorically extends the work of Goodman et al., (1987) to argue that hogs are not only industrialized within a capitalist food system, but now hog flesh is able to supplant or be used interchangeably with other forms of protein – a sort of proteinaceous substitutionism: the creation of generic, atomized, protein inputs. Commodity hogs are so valueless, the animal now exists to be a source of cheap protein.

Overview of Ecology and Aspects of Antibiotic Resistance in Campylobacter spp. Isolated from Free-Grazing Chicken Tissues in Rural Households.

Rural households all over the world rear backyard chicken mainly for their own consumption and, to a lesser extent, for barter trade. These chickens represent a staple dish with numerous culinary variations and a cheap source of protein. Although some Campylobacter species, and particularly Campylobacter jejuni and Campylobacter coli, have been associated with industrial poultry carcasses, studies concerning the ecology of this genus in rural households do not exist. To assess the prevalence of Campylobacter species in the tissues of backyard chickens, samples were collected from birds Gallus domesticus bred in households in the rural area of Epirus (Greece), and Campylobacter strains were isolated by quantitative methods at 37 °C and 42 °C. In total, 256 strains were identified, belonging to 17 Campylobacter species, with C. jejuni and C. coli being the most prevalent. From the four ecological parameters studied (size of the flock, presence of small ruminants in the same household, presence of other poultry species in the same household, and feeding leftovers of the household), the size of the flock and the presence of small ruminants and/or pigs in the same household mostly affected the distribution of these strains. To study the phenotypical resistance against 14 antibiotics, 215 strains were selected. The results showed a high prevalence of multidrug-resistance (MDR) strains extending to all classes of antibiotics. Further genome analysis revealed the presence of genes coding resistance (blaOxA-61, tet(O), tet(A) cmeA, cmeB, cmeC, and gyrA (Thr-86-Ile mutation)), with the efflux pump CmeABC being the most prevalent. All antimicrobial resistance-encoded genes co-circulated, except for blaOXA-61, which moved independently. The minimum inhibitory concentration (MIC) values of two out of three antibiotics (representing different classes) were reduced when the strains tested were exposed to carbonyl cyanide 3-chlorophenylhydrazone (CCCP), a known efflux pump inhibitor. The same result was obtained with the addition of CCCP to the MIC values of bile salts. These results lead to the conclusion that Campylobacter species are present in an impressive diversity in backyard chicken tissues and that they exert a significant resistance to antibiotics, raising a potential danger for public health.

Assessment of Epizootic Ulcerative Syndrome (EUS) in Estuarine Fishes Collected from Arasalar Estuary, Puducherry State, India

Fishes form an important source of cheap protein for people of many countries. The majority of the global production comes from freshwater aquaculture (58%) followed by marine (36%) and brackish water (6%). With an average increase in aquaculture production of 11% during the last decade, aquaculture has become the fastest growing sector of the world food economy However, fish diseases is now posing a great threat to achieve maximum production and has become a limiting factor to the success of aquaculture. Among the various diseases, Epizootic Ulcerative Syndrome (EUS) is a disease affecting a wide range of wild and farmed freshwater and estuarine fish which has spread across south-east Asia and India. From the fish survey, Food Fishes were collected from the Arasalar estuary, Puducherry State, India. The fish caught were identified and average 200 species of each fish were examined for EUS (Epizootic ulcerative syndrome) infection for the four seasons of the year (Pre-summer, Summer, Post-summer and Rainy season). The results of the number of fishes with EUS that could be identified in the different seasons are reported. Of the 75 fishes, that were examined, 12 were affected with EUS. This shows that 16% of the fishes were subjected to infection.&#x0D; Among Lizaparsia, 11 species were infected representing 14.6% of infection and among Mystus, seven fishes were infected forming 9.3% of infection. With regard to Oreochromis mossambicus, only four species were infected forming 5.3% of infection. With regard to Glossogobius giuris, nine species were infected thus 12% of infection. Nevertheless, during this period, the range of infection ranged from nil to 16%.&#x0D; During the pre-summer season, the percentage of infection again ranged from nil but to 12%. The maximum infection was noticed in Liza parsia (9 fishes) representing 12% infection, Puntius filamentosus (8 fishes) recording 10.6% followed by Glossogobius and Mystus (8%) and Oreochromis mossambicus (1.33%) infection respectively. During the summer and the post-summer season, none of the fishes that were investigated recorded any signs of EUS. Thus, an overall comparison reveals that the highest percentage of EUS was recorded in the rainy season followed by the pre-summer season and least in summer and post-summer season.

Gastrointestinal helminths in tilapia (&lt;i&gt;Oreochromis niloticus&lt;/i&gt;) sold for human consumption in Maiduguri, Nigeria: A potential public health risk

Fish is an important and cheap protein source for human consumption in developing countries. It is the second most popular source of protein diet in both rural and urban communities in Nigeria. Fisheries resources contribute about 5.40% to the nation's gross domestic product (GDP) through income generation, employment, food security, and foreign exchange earnings. Despite the significant contributions of fisheries to the Nigerian economy, the aquatic ecosystem is prone to pollution from human activities which increases the chances of transmission of parasitic infections, which are detrimental to aquatic and human life. The present study assessed the prevalence of gastrointestinal helminths of tilapia fish from different market sources in the Maiduguri metropolitan council of Borno State, Northeastern Nigeria. Samples of fresh Nile tilapia (Oreochromis niloticus) fish (n= 125), comprising 50 juveniles and 75 adults, were screened for gastrointestinal helminths using standard parasitological methods. Twenty-nine (23.2%) harboured at least one helminth parasite. Of the 29 positive individual fish samples, 16% (n=20), 4% (n=5), 2.4% (n=3), and 0.8% (n=1) were infected by Acanthocephala, Cestode, Nematode, and Trematodes, respectively. The infection rate was higher in adults (26%) than juveniles (18%) and in females (23.5%) than males (22.8%). Fish samples from Baga markets showed higher infection rates than the other two market sources. Sex, age, and location were not significantly associated with parasite recovery rate (p&gt;0.05). The study concluded that Nile tilapia fish sold in Maiduguri metropolis were infected with different groups of helminths, underscoring public health risks to farmers, sellers, and consumers. Therefore, fish farmers should regularly consult veterinarians for advice on good fish management practices and observe proper hygienic handling of harvested fish at the farm level, during transportation to fish markets, and processing. The public should thoroughly clean and properly cook fish for human consumption.

Nutritional Value of Soybean under Outdoor Hydroponics and Soil Conditions of the Ararat Valley

Background: Population growth increases the demand for food all over the world. According to the Food and Agriculture Organization of the United Nations, by 2050 the world population will reach 9.1 billion people, for whom food production is expected to increase by 25-70 %. That will lead to an increase in the demand for alternative farming technologies allowing us to ensure higher yields in less time. One such alternative and highly profitable plant growing technology is soilless culture or hydroponics. Climate change, improved technological capabilities, and need to increase self-sufficiency are good reasons for the introduction of soybean in Armenia.Soy, as one of the richest and cheapest sources of protein, plays an important role in the diet of people in many countries. The seed of soybeans contains 17 % oil and about 50 % protein. Because soybeans contain no starch, they are a good source of protein for diabetics.Objective: To establish the possibility and efficiency of soybean cultivation in Ararat Valley by traditional agricultural method and by the regulated hydroponic system and to investigate the nutritional value of soybean seeds.Results: The cultivation method had some influence on soybean yield and on the biosynthesis of several nutritional components. Thus, soilless culture conditions contributed to the increase in soybean yield: the weight of seeds obtained from one plant was 38.7 g while in the soil it was only 19.9 g. Soil plants were distinguished by the maximum accumulation of fat (28.9 %), while hydroponic ones by the maximum content of protein (31.5 %) and sugar (6.3 %).Conclusion: The obtained results established the effectiveness of soybean cultivation in Armenia. The regulated hydroponic method ensures obtaining about 11.6 tons ha-1 of soybean seeds, 3.7 tons ha-1 of protein and 2.6 tons ha-1 of fat. The work was supported by the Science Committee of the Republic of Armenia, in the frames of the research project N 21T-4B167.Keywords: Glycine max (L.) Merr., soilless culture, proteins, fats, sugars

Growth Pattern and Physiological Response of Japanese Quails to Administered Aqueous Solution of Egg Lime Molasses Mixture

Background: Japanese quails have the potentials of being cheap source of animal protein. This study was conducted to determine the growth pattern and physiological response of Japanese quails to administration of aqueous solution of egg lime molasses mixture (ELM). Methods: ELM was prepared by placing fresh eggs in a bowl after which 1 liter of lime juice and 500 g of molasses were added and left for 10 days at temperature of 27°C and relative humidity of 61%. The entire solution was then blended together. Two hundred day old Japanese quails were assigned to five treatments (4 replicates/treatment) with forty birds in a completely randomized design (CRD). The control (T1) having no administration of ELM, T2 had an inclusion level of 10 ml, T3: 20 ml, T4: 30 ml and T5: 40 ml ELM all into 500 ml of water. Feed and water were offered ad libitum. The study was carried out for 49 days. Data were collected on growth, morphometrics and key physiology parameters. Data were subjected to descriptive statistics and Analysis of Variance using SPSS Version 22. Result: Significant difference (p less than 0.05) was observed only for feed conversion ratio at the starter phase, however, birds administered 20 ml ELM/500 ml of water had the best FCR. Significant differences (p less than 0.05) were observed for live weight and weight gain at the finisher phase. Significant differences (p less than 0.05) were observed in body morphometrics with birds administered 20 ml/500 ml of water having the highest values. There were significant differences (p less than 0.05) in rectal temperature and respiratory rate at the starter phase while at the finisher phase, significant difference (p less than 0.05) was only observed in rectal temperature. It can be concluded from this study that aqueous administration of egg lime molasses solution in the diet of Japanese quails has no detrimental effect on the growth pattern and physiological response.

Sources and Health Risks of Inorganic Toxicants in Gallus Gallus Domesticus (Broilers) in Uyo, Nigeria

Poultry-related foods are consumed as good and cheap sources of protein globally. This research investigated the levels of Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn in poultry feeds, water samples, and broilers obtained from poultry farms randomly sampled within Uyo Metropolis. These poultry-related products were obtained, treated, and analysed spectrophotometrically using standard analytical techniques. Results showed that, the concentrations of all the metals in poultry feeds and broiler meat were within their recommended limits however, mean levels of Cd and Fe in water sample was higher than their permissible limits. Concentrations in poultry feeds were generally higher than their levels in broiler meat. Multivariate analyses indentified varied factors responsible for the accumulation of these metals in feeds, water samples, and broiler meat examined. The estimated daily intake (EDI) of Cd, Fe, and Zn were higher than their oral reference doses (Rfds) for both the children and adults’ populations. The hazard quotients (HQ) of Cd, Fe, Pb, and Zn for both populations were also higher than one (1). The hazard index of the metals for populations were higher than one but, the children class were more susceptible to non-carcinogenic risks. The incremental lifetime cancer risk (ILCR) for the carcinogens varied between medium to very high cancer risk classes. The total cancer risk (TCR) for the children and adults’ populations were 1.54E-01 and 1.43E-01, respectively higher than the standard limits. The relative risk (RR) analysis identified Cd as metal with the highest potential to cause cancer and non-cancer risks in the consumers of broiler meat from the studied poultry farms. This study has indicated the significance of assessing poultry feeds and related products to establish to the quality.

Effects of traditional brewery dried residue and field pea hull mixtures supplementation on feed utilization and performance of Washera sheep fed natural pasture grass hay as basal diet.

The major feedstuffs (natural pasture and crop residues) used for sheep in Ethiopia are fibrous and the crude protein (CP) content is less than 7% that is inadequate to meet the maintenance requirement of sheep. These poor quality feeds should be improved and can be improved through supplementation with nutritious feedstuff. Therefore, to overcome this challenge, there is a need to look for some alternatives but locally available and cheap sources of protein. In this regard, traditional brewery dried residue (TBDR) and field pea hull (FPH) could be an important sources of feed for ruminant livestock. This experiment was carried out to evaluate the effects of supplementing mixtures of TBDR and FPH on the feed intake, digestibility, live weight gain, and economic feasibility of the feeding treatments. In a 3-month experiment, 20 yearling intact male Washera sheep were blocked based on their initial BW of 22.1±1.58kg (mean±standard error of mean), and treatment diets were randomly assigned within a block. Treatments comprised feeding natural pasture grass hay (NPGH) ad libitum+50g ground nut cake (GNC) (T1 , control); T1 +supplemented with 25% TBDR:75% FPH (T2 ); T1 +50% TBDR:50% FPH (T3 ) and T1 +75% TBDR:25% FPH (T4 ). The supplement feed was offered twice a day at 08:00 and 16:00 while, common salt lick and water were available all time. NPGH, FPH, TBDR, and GNC in the current study contained 5.7%, 13.4%, 22.2%, and 45.4% CP and 62%, 61%, 34%, and 20% neutral detergent fibre, respectively. Sheep in supplemented treatments had higher (p<0.05) apparent digestibility percentage of dry matter and nutrients than those in T1 . Among the supplemented treatments, sheep fed T4 recorded 4.49kg extra (p<0.0001) body weight as compared to that fed T1 by growing at an average of 49.8g/day and returned the highest net income (255.8 Ethiopian birr) CONCLUSION: Thus, based on the highest body weight gain and net return, the combinations of 75% TBDR and 25% FPH (T4 ) appeared to be recommendable for poor farmers.

ANALYSIS OF CONSUMER BEHAVIOUR IN THE EUROPEAN POULTRY MEAT MARKET

This research has also confirmed that poultry meat is currently in its golden age, not only in our country but also globally. The beneficial physiological effects of poultry meat, its nutritional value (high protein content), and its role in modern nutrition and diets have made it the most popular and 'fashionable' meat product of our time. Healthiness as a megatrend has favoured the consumption of poultry meat, which has been consumed for decades, and is reflected in the growth in production, trade and consumption. The trend of environmental awareness has also pushed the meat market towards the consumption of poultry meat as it is one of the least environmentally intensive compared to other meat types. Poultry meat is the second most commonly consumed meat in the EU, but in some European countries, it has taken over the overall lead (e.g. Hungary, Cyprus, and the UK). Poultry is not only preferred for its healthiness and low environmental impact, it is also an easy, versatile, quick-to-prepare, cheap source of protein. These advantages are expected to lead to further growth in the future in terms of production, trade and consumption, China, the US, the EU and Brazil dominate the poultry sector.

Effect of partial replacement of soybean meal by sesame seed cake on diet stability and growth performance of common carp Cyprinus carpio

This study was conducted under laboratory conditions to evaluate the effect of sesame seed (Sesamum indicum) cake (SSC) as a protein source by a partial replacement of soybean (Glycine max) meal (SBM) on diet stability and growth performance and some productive traits (final weight, total weight gain, specific growth rate, relative growth rate, feed conversion rates and condition factor) of common carp (C. carpio). The experiment consisted of ten treatments with two replications for each treatment, where SSC was used instead of SBM in three types of treatments: row, soaked and phytase enzyme addition in T1, T2 and T3 with three different substitution ratios 10%,20% and 30% in D1, D2 and D3 and treatment without SSC (control group) in T0D0 . The results showed that the diet stability was unaffected by inclusion different levels of SSC, while results of growth performance showed that the replacement of 30% SSC instead of SBM with the addition of phytase enzyme improved significantly (p≤0.05) all growth parameters and some productive traits (final weight, total weight gain, specific growth rate, relative growth rate, feed conversion rates and condition factor), In addition, the results showed that the use of sesame seed cake in raw or soaked form does not negatively affect the growth parameters of the fish. Therefore, sesame seed cake can be used as a cheap source of protein in common carps C. carpio diets.

EFFECT OF DIETARY SUPPLEMENTATION OF ANIMAL BLOOD PLASMA POWDER ON PRODUCTION PERFORMANCE, DRESSED WEIGHT AND IMMUNE RESPONSE OF BROILER

Enhancing economical poultry production using low-cost animal blood plasma powder incorporated in poultry rations is a good step toward sustainable poultry production. The purpose of the present study was to evaluate the effect of dietary supplementation of animal blood plasma powder on production performance, dressed weight, and immune response of broilers. Bovine plasma was separated from the whole blood through centrifugation. A total of 240 day-old broiler chicks having uniform body weights were randomly assigned into 4 treatment groups (AP0, AP1, AP2, and AP3). Each group had three replicates of 20 chicks (n=3; 20 birds/replicate). Ross broiler management guidelines were followed for feeding, watering, and vaccination. broiler starter ration (23.2% CP and 2990kcalME/kg) was provided during the brooding stage and switched to the grower diet (20.08% CP and 3112 kcal/kg ME) up to 28 days and finisher (18.86% CP and 3208 kcal/kg ME). Animal blood plasma powder supplemented into the diet at different levels AP1 (0.5g/kg), AP2 (1g g/kg), AP3 (1.5g g/kg), and AP0 (Control 0g/kg) for different groups. The treatment was continued for seven weeks. Significantly lower (P&lt;0.05) feed intake (2809.3g±5.36) and high body weight gain (1513.3g±9.83) were found for the higher supplemented group compared to the non-supplemented group (1441.0g ±4.04). Overall FCR was significantly (p&lt; 0.05) lower for supplemented groups compared with the control group. The decreasing (p&lt; 0.05) trend in FCR in supplemented groups was increasing the level of bovine animal blood plasma supplementation in the diet. The dressing percentage was significantly (P&lt;0.05) higher for supplemented groups as compared to the control. Non-significant differences were observed in haemagglutination inhibition (HI) antibody titer against Newcastle disease and mortality among groups. It was concluded that animal blood plasma could be safely used in broiler ration for better performance without any loss to antibodies titer and mortality. Animal blood plasma has more capability to be used as an alternative and cheap source of protein in poultry ration.

An Overview of Pulses Production in India: Retrospect and Prospects of the Future Food with an Application of Hybrid Models.

Forecasts are valuable to countries to make informed business decisions and develop data-driven strategies. The production of pulses is an integral part of agricultural diversification initiatives because it offers promising economic opportunities to reduce rural poverty and unemployment in developing countries. Pulses are the cheapest source of protein needed for human health. India's pulses production guidelines must be based on accurate and best forecast models. Comparing classical statistical and machine learning models based on different scientific data series is the subject of high-level research today. This study focused on the forecasting behaviour of pulses production for India, Karnataka, Madhya Pradesh, Maharashtra, Rajasthan and Uttar Pradesh. The data series was split into a training dataset (1950-2014) and a testing dataset (2015-2019) for model building and validation purposes, respectively. ARIMA, NNAR and hybrid models were used and compared on training and validation datasets based on goodness of fit (RMSE, MAE and MASE). This research demonstrates that due to the diverse agricultural conditions across different provinces in India, there is no single model that can accurately predict pulse production in all regions. This study's highest accuracy model is ARIMA. ARIMA outperforms NNAR, a machine learning model. Pulse production in India, Rajasthan, and Madhya Pradesh will expand by 26.11%, 12.62%, and 0.51% from 2020 to 2030, whereas it would decline by -6.5%, -6.21%, and -6.76 per cent in Karnataka, Maharashtra, and Uttar Pradesh, respectively. The current forecast results could allow policymakers to develop more aggressive food security and sustainability plans and better Indian pulses production policies in the future.
