Genetic features of avian influenza (A/H5N8) clade 2.3.4.4b isolated from quail in Egypt

Several genotypes of the highly pathogenic avian influenza (HPAI) virus H5N8 subtype within clade 2.3.4.4b continue to circulate in different species of domestic birds across Egypt. It is believed that quail contribute to virus replication and adaptation to other gallinaceous poultry species and humans. This study provides genetic characterization of the full genome of HPAI H5N8 isolated from quail in Egypt. The virus was isolated from a commercial quail farm associated with respiratory signs. To characterize the genetic features of the detected virus, gene sequencing via Sanger technology and phylogenetic analysis were performed. The results revealed high nucleotide identity with the HPAI H5N8 virus from Egypt, which has multiple basic amino acid motifs PLREKRRKR/GLF at the hemagglutinin (HA) cleavage site. Phylogenetic analysis of the eight gene segments revealed that the quail isolate is grouped with HPAI H5N8 viruses of clade 2.3.4.4b and closely related to the most recent circulating H5N8 viruses in Egypt. Whole-genome characterization revealed amino acid preferences for avian receptors with few mutations, indicating their affinity for human-like receptors and increased virulence in mammals, such as S123P, S133A, T156A and A263T in the HA gene. In addition, the sequencing results revealed a lack of markers associated with influenza antiviral resistance in the neuraminidase and matrix-2 coding proteins. The results of the present study support the spread of HPAIV H5N8 to species other than chickens in Egypt. Therefore, continuous surveillance of AIV in different bird species in Egypt followed by full genomic characterization is needed for better virus control and prevention.

Empowering Communities to Reduce Dependence on Unlicensed Mining and Minimize Corporate Losses: A Case Study of PTBA in December 2023

This study aims to analyze the impact of community empowerment programs on reducing dependence on unlicensed mining and to measure the potential losses incurred by PTBA due to these activities. The time sample used in this research is December 2023. A quantitative approach is used to calculate the income earned by the community from six empowerment programs, including bamboo downstream processing, snakehead fish farming, reclamation plant cultivation, maggot farming, quail farming, and eel farming. The total income generated by these programs for 93 beneficiaries reached USD 13,238.22 per month, with an average income per program ranging from USD 153.70 to USD 244.39, which remains below the regional minimum wage (UMR) of Muara Enim Regency, set at USD 233 per month. This income is compared to assess how competitive the alternative livelihoods provided by the empowerment programs are. In addition, this study calculates PTBA’s losses from unlicensed mining in the same month, based on the extraction of 0.175 million tons of coal, the market price of USD 58.28 per ton, and the lost royalties of 8%. The total financial loss reached USD 10.2 million, with USD 815,920 in lost royalties. The analysis underscores the importance of expanding and strengthening community empowerment programs to further reduce unlicensed mining activities, while also mitigating the financial and environmental impacts on the company.

Plasma activated water effects on behavior, performance, carcass quality, biochemical changes, and histopathological alterations in quail

BackgroundPlasma-activated water (PAW) is an innovative promising technology which could be applied to improve poultry health. The current study investigated the effects of drinking water supply with PAW on quail behaviour, performance, biochemical parameters, carcass quality, intestinal microbial populations, and internal organs histopathology. A total of 54 twenty-one-day-old Japanese quail chicks were randomly allotted to three treatments provided with PAW at doses 0, 1 ml (PAW-1), and 2 ml (PAW-2) per one litter drinking water. Each treatment contained 6 replicates (3 birds/ cage; one male and two females).ResultsThe results clarified that there were no significant (P > 0.05) changes in behaviour, and performance. For the biochemical indicators, the PAW-1 group showed significantly higher serum H2O2, total protein and globulin levels compared with the other groups (P = 0.015, < 0.001, and 0.019; respectively). PAW groups had significantly lower serum creatinine and urea levels than the control (P = 0.003). For the carcass quality, the internal organs relative weight between different treatments was not changed. In contrast, there was a significant increase in the meat colour, taste, and overall acceptance scores in PAW groups compared with the control one (P = 0.013, 0.001, and < 0.001; respectively). For the intestinal microbial population, lactobacilli count was significantly higher in PAW-2 compared with the control group (P = 0.014), while there were no changes in the total bacterial count between different treatment groups. Moreover, mild histological changes were recorded in the intestine, liver, and spleen of PAW groups especially PAW-2 compared with the control one.ConclusionsPAW offered benefits, such as reducing creatine and urea levels, improving meat characteristics, and increasing lactobacilli count, all of which are crucial for sustainable quail farming. Therefore, further research is needed.

Metabolism and productivity of quails of Estonian breed when feeding the feed additive Krezatsin

The purpose of the work was to establish the metabolism and productivity of quails of Estonian breed when fed with the Krezatsin feed additive. Under the conditions of a quail farm, the feasibility of using the feed additive Krezatsin in the diets of quails of Estonian breed has been scientifi cally substantiated and proven. Its optimal dose in compound feed for quails has been identifi ed. It has been shown that the use of the Krezatsin additive in feeding quails increased the nutritional value of their feeding, had a positive effect on digestibility, the use of dietary nutrients, growth energy, the livability of quails, their egg and meat productivity. The use this additive reduced feed intake per unit of production. The data obtained in the experiment made it possible to theoretically substantiate and recommend additional resources for production to increase the effi ciency of quail production by optimizing the Krezatsin feed additive in their diets. It has been proven that the use of this additive when rearing quails in an amount of 50 mg per 100 g of compound feed contributed to the normalization of metabolism in the body of quails, significantly increased the digestibility of dry matter by 2,25 abs.%, organic matter by 2,16 abs.%, raw protein by 3,38 abs.%, crude fat by 2,67 abs.%, crude fi ber by 2,76 abs.% and nitrogen-free extractive substances by 1,16 abs.%. The tested additive contributed to better nitrogen absorption and use of macroelements diet. Feeding the studied additive as part of the compound feed contributed to an increase in the live weight of quails by 3,4 %, egg productivity by 6,0 %, improved the quality of eggs and reduced the compound feed intake per unit of production by 3,4 %.

Пищевой рацион перепела в осенний период в Ставропольском крае

Quails (Coturnix coturnix (Linnaeus, 1758)) are the only migratory Galliformes species. Quails are nestling ground-dwelling birds, feeding on seeds and crawling insects. Wild quails inhabit many parts of Russia. Quail farming is quite popular because quail meat is low in calories and possesses a number of beneficial properties, e.g., it is rich in proteins, contains little fat and virtually no carbohydrates, etc. As a rule, quails winter in Transcaucasia and Southern Europe; however, they sometimes prefer to stay in southern regions for the winter. This article introduces the autumn food habits of quails in the Central Ciscaucasia.&#x0D; The research relied on the analysis of stomach contents of 156 birds killed by hunters or hit by vehicles in several districts of the Stavropol Region. The material was collected in the autumn in 2008–2021.&#x0D; In the Central Ciscaucasia, quails are mesophiles and inhabit abandoned wheat and pea fields. The population fluctuates from year to year, depending on spring weather conditions. Their optimal nestling grounds include irrigated fields and areas near canals and ponds. In the steppe regions, they prefer agricultural areas, e.g., orchards, vineyards, holiday villages, sheep sheds, green belts along fields, roads, and railways, etc. Being phytophages, they rely on plant and, to a lesser extent, animal forage. &#x0D; In the autumn, they feeding on green plants, wheat grain, seeds of cultivated and wild plants, and insect larvae.

Hulless barley as part of the diets for quails of the parental herd

Every year in our country the production of poultry products increases. Currently, in many countries of the world quail farming is intensively developing, the task of which is to meet the needs of the population with high-quality and environmentally friendly eggs and meat that have dietary properties. A priority direction in the development of modern poultry farming is the search for new cost-effective and highly effective feed products based on local raw materials that can provide a solution to the problems of complete feeding. Currently, the search for new sources of grain crops with high protein and energy nutrition is relevant. The introduction of hulless barley varieties with a fiber content of 1,6 to 2,8 % into compound feed will increase the digestibility of nutrients. Therefore, the use of hulless barley as part of feed for quails is of certain feasibility. The purpose of the work was to establish the eff ect of compound feed with hulless barley on animal science and economic indicators when housing quail parental herd. The results of a research with the introduction in the diets of quail of 10 % hulless barley and its eff ect on the productivity of the parental herd have been presented in the article. It was established as a result of the research that the use of compound feed with the introduction of 10 % hulless barley for quail parental herd contributed to a reduction in the prime-cost of production of hatching eggs by 7,13 %, due to an increase in the productivity of laying quails by 11,38 % and the reduction in feed expenditures per 1 kg of egg mass and for 10 eggs by 5,09 and 1,70 %, respectively. It was established when carrying out a balance experiment that the use of the developed compound feed for poultry in the experimental group increased the digestibility of nutrients such as crude protein by 1,46 abs.% and crude fiber by 4,34 abs.%.

Technical-Economic Diagnosis and Development Prospects of Quail Farming in Burkina Faso

Poultry farming is a livestock sector that encompasses various bird species, with the most well-known in Burkina Faso being chickens and guinea fowl. These two species receive support from development programs as they significantly contribute to the livelihoods of poor populations. Quails have been recently introduced, presenting technical and economic advantages that could contribute to the development of livestock farming. The study aimed to characterize the profile of stakeholders, conduct a techno-economic diagnosis, and suggest development prospects. Thirty-three farming units were surveyed in the cities of Bobo Dioulasso, Ouagadougou, and Orodara. The socio-demographic aspects of quail farmers, zootechnical aspects of quails, and challenges faced were analyzed.On the socio-economic level, the activity is predominantly practiced by young, educated men, exclusively with secondary and higher education. Zootechnically, the animal productions consist of eggs and meat. Quail production goals prioritize egg production, quail chicks (97%), fattening (76%), and breeder farming (48%).The feeding practices are inadequate, as all farmers (100%) were providing quails with feed intended for laying hens or broilers. Breeding quails reach sexual maturity at 6 weeks, with an average of 250 eggs laid per female and a high hatching rate. Quails also exhibit a high level of hardiness, easily adapting to their environment, and a high level of adaptation to climatic factors (85% of farmers).Quail housing exclusively consists of battery cages. Economically, live quail prices range from 1,500 to 3,000 Fcfa for breeders and consumption quails, and from 2,500 to 4,000 Fcfa for a tray of thirty eggs. Income levels varied from 184,470 to 28,642,945 Fcfa from quail sales. The revealed constraints primarily involve marketing, followed by the issue of inadequate feeding.

Sociotechnical characterization of quail farming in the autonomous district of Abidjan, Côte d'Ivoire

The present study was conducted among 100 poultry farmers through a formal survey from July to December 2021 in the autonomous district of Abidjan (Côte d'Ivoire). With no information on quail farming organization, the objective was to understand the social and technical characteristics. It appears that the municipality of Bingerville has a significantly higher difference than the other municipalities (p &lt; 0.05), unlike Marcory, which has the lowest rate of farms. Quail farming consists of 8% nationals and 92% non-nationals, with 89.8% men and 10.2% women, of which those in the age group of 30 to 45 years account for 65.31% (p &lt; 0.01). The age groups of 45 years and above, and 20 to 30 years represent 18.37% and 10.20%, respectively. Among the 98% educated quail farmers, 48.98% have a higher education level, 38.78% have a secondary level, and 10.20% have a primary level. As for quail farming experience, 71.43% have less than 3 years, 14.29% have between 3 and 6 years, and over 6 years. Furthermore, the farms are of mono-specific type (14.29%) and plurispecific type (85.71%) with cage housing (72.45%) and floor housing (27.55%). The quails, originating from hatcheries (8.16%) or purchased (91.84%), are managed in single flocks (85.71%) or multiple flocks (14.29%) for the purpose of reproduction (97.96%) or meat production (14.29%). Quail farming is practiced by all populations with diversified techniques in the district.

Differential diagnosis of Eimeria species in farmed Japanese quails (Coturnix japonica)

Similarly to poultry industry, coccidiosis may cause significant economic losses also in the commercial quail industry, an emerging sector undergoing uneven development around the world. Although scant and mostly dated, the available literature reports detailed morphological and morphometric features of both oocysts and sporocysts of the Eimeria species hitherto recognized in Japanese quails, i.e. E. tsunodai, E. uzura, E. bateri, and E. fluminensis. Mixed infections are very common in the field and require an accurate differential diagnosis of diverse species of coccidia, identifying the highly pathogenic ones, in particular E. tsunodai (localized in the caeca), and E. uzura (localized in both caeca and small intestine). This goal is hampered by time-consuming laboratory procedures involving highly qualified staff and facilities, and poorly compatible with routine management practices in farmed quails. A supplemental difficulty is represented by the lack of nucleotide sequences available in GenBank. To overcome these issues, copromicroscopic and molecular analyses (amplifying the 18S rRNA region, and the internal transcribed spacers regions ITS1-5.8rRNA-ITS2) were performed on oocysts populations separately isolated from pools of 12 caecal and 12 cloacal contents collected from 240 naturally infected laying Japanese quails. Data on morphological and morphometric features of 1,000 sporulated oocysts were statistically compared, demonstrating the presence of different Eimeria species colonizing the 2 intestinal tracts. This result was also confirmed by PCR and phylogenetic analysis of the 18S rRNA gene. Overall results allowed to hypothesize the presence of E. uzura in our Japanese quails. Although a certain identification at species level was not obtained, the present study demonstrates that reasonable turnaround times of monitoring procedures performed on Japanese quail farms, shedding light on the in vivo and post-mortem differential diagnosis of coccidiosis can be achieved, and provide obvious benefits in disease understanding and control.

Quail Farming in Villages of Mogoditshane-Thamaga and Tlokweng Districts, Botswana

A The interest in quail farming has been increasing over the years due to the quail’s many productive and financial benefits over other poultry species. Quail farming is still in its infancy in Botswana. This study investigated the current status, challenges, and prospects of Japanese quail farming in Mogoditshane, Gabane, and Tlokweng districts, Botswana. A total of 64 quail farmers were interviewed using a structured questionnaire from June 2022 to April 2023. Data were collected on the respondents’ demographic characteristics (age, educational status, and sex), quail management aspects (feeding, housing, and health), ownership of quail, challenges in quail farming, and the use of quail products in the study area. Results showed that 67% of male respondents were involved in quail rearing. The youth (≤35 years) dominated the rearing of quails, followed by respondents aged 41-50 years (22%), 36-40 years (16%), and above 50 years (9%). In addition, 48% of the respondents reared ≤100 quails, followed by 39% and 13% who reared 101-500 and 500 quails, respectively. Furthermore, 81% of respondents reared quails in cages, 17% in conventional structures, and 2% in residential houses. Bobwhite, Jumbo, and Japanese quail were the three quail varieties reared in the study area. It was found that 55% of the respondents had less than one year of experience in quail farming. Moreover, 86% of the respondents used crushed maize or sorghum to feed quails, while 14% used commercial chicken diets. Finally, 92% of the respondents mentioned that quail eggs were used to treat various human diseases. Effective challenges in quail farming included external parasites (36%), diseases (30%), predation (13%), lack of commercial quail diets (12%), escaping (6%), and theft (3%). Quail farming should be considered for inclusion in government support programs as it has the potential to contribute to income generation and food and nutrition security.

Effect of Almond and Thyme Oils on the Nutritional Profile of Broiler and Quail Meat

Broiler and quail farming have experienced significant growth in Pakistan. Broiler chickens are primarily raised for their meat, whereas quails are raised for both their meat and eggs. This study aims to assess the quality and shelf life of broiler and quail meat when treated with thyme and almond essential oils and stored under refrigeration at 4℃. Proximate analysis was conducted on the quail and broiler meat samples, assessing moisture, ash, protein, and fat content to evaluate their nutritional value. Nanoemulsions of thyme and almond oil were prepared at two different concentrations (15% and 25%) and applied to the meat samples, which were then divided into five groups: a control group and four treatment groups. The four treatment groups were labelled as 15% thyme, 25% thyme, 15% almond, and 25% almond. The meat samples were analyzed for their proximate composition (moisture, ash, protein, and fat) and pH levels on the first, seventh, and twenty-first days of the experiment. Fresh samples of chicken and quail meat exhibited significant differences in moisture, ash, proteins, and fats, while pH levels remained relatively stable. On the 7th and 21st days, there was an observable increase in ash, protein, and fat values across all experimental groups, while pH levels remained relatively unchanged. Broiler meat had the highest protein content, while quail meat contained the highest fat levels. Among the treatments, it was observed that thyme oil at a 25% concentration yielded the best results for preserving nutritional values close to their initial levels when compared to the other experimental groups. Based on the study's findings, it is reasonable to conclude that thyme oil, in comparison to almond oil, maybe a more effective option for preserving meat and extending the shelf life of stored meat.

Commercial Feed Substitution with Milkfish Waste Flour (Chanos chanos) Against Quail (Coturnix coturnix japonica) Egg White Index, Egg Yolk Index and Haugh Unit

Quail farming is quite developed, from year to year the population increases. The search for alternative feed as a substitute for feed sources is an effort by breeders to minimize feed costs. One alternative to replace feed ingredients can be fishery industry waste. Fishery waste that can be used as feed is milkfish waste (Chanos chanos). The purpose of this research was to determined the substitution of milkfish waste flour (Chanos chanos) at commercial feed to egg white index, egg yolk index and haugh unit. There are 20 quails (Coturnix coturnix japonica) at one day of age of four treatments and five replications. Each treatment consisted by five females. The treatment consisted of P0 with commercial feed 100%, P1 with commercial feed 98% + milkfish waste flour 2%, P2 with commercial feed 96% + milkfish waste flour 4% and P3 with commercial feed 94% + milkfish waste flour 6%. Based on results of the Analysis of Variance (ANOVA) there was not significantly different (p&gt;0,05) on egg white index, egg yolk index and haugh unit. It can be concluded the substitution of commercial feed with milkfish waste flour (Chanos chanos) can maintain egg white index egg yolk index and haugh unit.

Pemberdayaan Masyarakat Desa Oeltua melalui Peternakan Puyuh Berbasis EM4 dalam Mendukung Masyarakat Anak Bebas Stunting

Stunting is a child health problem caused by a child's failure to grow according to the child'sgrowthstandards. Stunting can be prevented by consuming animal protein such as eggs and meat. Animal protein contains essential amino acids needed for children's growth. Oeltua Village, Kupang, has a low per capita income value, which has an impact on the community's nutritional intake being unbalanced and resulting in children having the potential to be stunted and stunted. Quail farming can provide people's animal food needs in eggs and meat. EM4-based quail farming can provide food sources of animal protein quantity and quality. PAR method was used in the empowerment; PAR method involves education and data collection on stunting, practice, assistance in raising quail using EM4, monitoring and evaluating quail production. The empowerment socialization was attended by 92% of mothers with toddlers, 5% of fathers accompanying mothers, and 3% of productive women. The health conditions were seven male and 14 female toddlers with the potential to be stunded; 4 male and three female toddlers were stunted. Quail egg production showed increased production in monitoring I‒VIII (27‒224). Egg production is 2‒5 days/house, and the average is 75‒135 months/house to fulfil children's protein needs. EM4-based quail farming can be implemented in the Oeltua Village community. Toddlers need a nutritional intake of animal protein, which can be fulfilled by consuming quail eggs to reduce the potential and incidence of stunting.

Influence of protein-vitamin mineral supplements on the splenic morphometric parameters of quails

Currently, a growing industrial poultry sphere in many countries is quail farming. Quails have a complex of unique economic-productive advantages, as compared with other poultry, – high body temperature, intensive metabolism, small size, fast maturation, and high egg productivity. In the study, we examined the specifics of microscopic structure of morphometry of the spleen of the control and experimental birds as characteristics sensitive to the action of supplements. The proposed methods are intended for studying effects of protein-vitamin mineral supplements on poultry farming. Therefore, for 21 days, with the main diet, the quails were given mineral supplements produced by the Multilife trade mark (crude protein, amino acids (lysine, threonine, methionine, cysteine), calcium, available phosphorus, sodium, chlorine, vitamins (A, D3, E)), by the Missi trademark (protein, vitamins, minerals), and by the Standard Agro trademark (soybean press cake, vitamins А, D3, Е, В1, В2, В6, В12), multi-enzyme complex, salt, ground limestone, phosphate monocalcium, amino acids (lysine, threonine, methionine with cysteine). This is the first study of the ultrastructural organization of the spleen of Japanese quail (Coturnix japonica) fed with protein-vitamin mineral supplements. The tested supplements were beneficial for the productivity of the quails, as evidenced by increase in the body and spleen weight. Body weight of the quails increased by 5.8% in the group that was fed additionally with the Multilife supplement, and by 12.5% in the group that consumed the Missi supplement added to the fodder, and by 8.1% in the group that consumed the Standard Agro supplement with the diet. At the same time, the spleen weight increased by 7.2%, 16.0%, and 10.5%, respectively. However, the relative weight (0.1%) underwent no changes, which characterizes this parameter as permanent for age and species of animals. Analysis of the data of our morphological studies revealed that the splenic microscopic structure of the quails was characterized by presence of support-contractile apparatus (capsule and trabeculae) with the relative area of 4.6 ± 0.8% and single radial trabecula. The parenchyma was formed by white and red pulps without distinct boundaries. In the white pulp, there were designated lymphoid nodes with no light centers, and also periarterial lymphoid sheaths and ellipsoids. In the reticular stroma of the white pulp of the spleen, we found blood cells of various maturity, in particular, lymphocytes, which were clearly divided into large, average, and small; mononuclear and multinuclear macrophages, which contained hemosiderin and melanin, leukocytes, mostly eosinophilous. The ultrastructural organization of the spleen of the quails had the following peculiarities: nuclei of leukocytes contained large nuclei, endotheliocytes of the central artery of lymphoid follicle performed phagocyte function by accumulating autophagosomes in its cytoplasm. In the quails that had consumed the diet containing supplements, the macroscopic, microscopic, and ultramicroscopic structures underwent no changes. At the same time, there was seen a tendency towards increase in the relative area of white pulp and the support-contractile apparatus. The relative area of white pulp of the spleen increased by 0.5% in the group of quails that had received the diet with the Multilife supplement, by 1% in the group that had consumed the diet with the Missi supplement, and by 0.6% in the group that had consumed the diet with the Standard Agro supplement. The relative area of the red pulp in the spleen of the quails was observed to have the tendency towards decrease: by 0.4% in the group that received the Multilife supplement, by 1% in the group that consumed the Missi supplement, and by 0.5% in the group that consumed the Standard Agro supplement. The relative area of the support-contractile apparatus of the spleen increased by 0.4% in the group of quails that consumed the Multilife supplement, by 1% in the group that consumed the Missi supplement, and 0.5% in the group that consumed the Standard Agro supplement. Taking into account the data we obtained, we may conclude that our studies confirm the benefits of using modern protein-vitamin supplements in poultry farming for stimulation of growth and development. Especially valuable is the absence of negative effect on the morphofunctional parameters of the spleen, which we used as biomarkers.
