Pengaruh Penggunaan Tepung Daun dan Batang Ubi Jalar (Ipomoea Batatas L) Dalam Ransum Terhadap Performans dan IOFC Ternak Babi Peranakan Landrace Fase Grower

Pig farming has great potential to be developed because it is efficient in converting feed into meat. Feed is the largest cost component in production, which is about 60-80% of the total cost. Landrace pigs are the main choice of breeders because of their fast growth and docile temperament. However, the high price of factory-made feed encourages farmers to look for alternative feed ingredients, including agricultural waste such as sweet potato leaves (Ipomea batatas L), which are rich in nutrients and relatively cheap (Sihombing, 2016). Sweet potato leaves contain 25.51% crude protein and various other important nutrients, but they also contain anti-nutrient substances such as tannins. The aim of this research was to determine the effect of giving of leaf and stems sweet potato meal (SPM) on performa and income over feed costs (IOFC) in the grower pig. A total of 12 female landrace pigs aged 3-4 months with an average body weight of 55.5 kg (CV = 24.23%) were used in this study. The experimental method used a randomized block design, with 4 treatments and 3 replications. The treatments tried consisted of R0: ration without sweet potato leaf and stems meal sweet potato (SPM), R1: ration 5% (SPM), R2: ration 10% (SPM) meal, R3: ration 15% (SPM). The variables studied were performa and Income Over Feed Cost (IOFC).The variables measured are ration consumption, body weight gain, ration conversion and Income Over Feed Cost (IOFC). The results of the analysis of variance (ANOVA) showed that the treatment had no significant effect (P>0.05) on feed consumption, body weight gain, feed conversion and Income Over Feed Cost of research pigs. It can be concluded that the use of leaf and stems meal sweet potato 5%, 15% in pig rations provide the same response to provide the same effect on body weight gain, ration conversion and Income Over Feed Cost (IOFC). leaves and stems sweet potato can be used up to 15%.

Biochemical indicators of pig blood when using a complex probiotic feed supplement

The use of probiotics in animal feed is one of the most promising alternatives to the application of antibiotics. In order to establish the effectiveness of the use of a complex probiotic supplement (Lactobacillus spp., Lactococcus spp., Spirulinaceae, Saccharomyces cerevisiae, Actinomycetaceae, Aspergillus spp. and Penicillium spp.) in pig farming, two groups of pigs of the Poltava Meat breed were formed by the analog method. In the ration of the fattening pigs of the experimental group, 1.0% of the mass of compound feed was replaced with a complex probiotic supplement, which was fed during the 45 days of the experimental period at the age of 135 to 180 days. In experimental pigs, biochemical blood parameters were determined (the content of protein, lipids, cholesterol, triglycerides, activity of aspartate aminotransferase and alanine aminotransferase, the content of creatinine, glucose, calcium, phosphorus, albumins and globulins) using test kits from the company "Filisit Diagnostics" (UA). As a result of the research, it was established that with the use of a complex probiotic feed supplement, the content of total protein in the blood serum of the pigs of the experimental group was higher by 18.4%, glucose by 21.4%, aspartate aminotransferase activity by 20.4%, alanine aminotransferase by 38.0% compared to control group. In both groups, regardless of the established difference, the named indicators were within the physiological norm. The concentration of cholesterol in the blood of pigs receiving the probiotic supplement decreased by 43.2%, but the concentration of calcium (by 26.2%) and phosphorus (by 17.9%) increased. In the experimental group, the blood indicators related to the immunity of pigs improved – the content of α1 and α2 globulins decreased by 4.1% and 7.4%, respectively. Also, in the experimental group, the concentration of albumins increased by 7.5%, which probably indicates an improvement in the functional state of the liver. As a result of feeding with a complex probiotic supplement in the experimental group the albumin-globulin ratio improved, which increased by 35.0%. Thus, the introduction of a complex probiotic feed additive into the ration of pigs changed the structure of the influence of exogenous and endogenous factors on metabolism, had a positive effect on the protein profile of the blood, and caused an increase of average daily gains in experimental animals by 5.8% compared to the control group.

Effect of Home-made Cooked Feed vs. Balanced Feed on Growth Performance and Benefit-Cost Ratio of Ghungroo and Large White Yorkshire Piglets Reared under Intensive System in Sundarban Area of West Bengal, India

Aims: The present study was carried out to analyze the growth performance and benefit-cost ratio (BCR) of Ghungroo and Large White Yorkshire (LWY) piglets reared under intensive housing by providing home-made cooked feeds and balanced feed. Place and Duration of Study: The study was conducted for a period of four months in Sundarban area of West Bengal, India. Methodology: A total of 12 (six males and six females) piglets of each grower weaned Ghungroo and LWY piglets were randomly selected. For control group, commercially available grower pig ration were offered and for treatment group, locally available cooked feeds were offered. The body weight (kg) measurements of both the groups were taken every month from 2 to 6 months of age. Benefit-cost ratio (BCR) was calculated. Results: The body weights obtained in groups fed with locally available cooked feeds and that of balanced ration are significantly different (P<0.05) to each other. The body weight of both Ghungroo and Large White Yorkshire (LWY) piglets in treatment group was significantly (P<0.05) less than that of the control group from 3 to 6 months of age. LWY piglets had significantly (P˂0.05) higher body weight than Ghungroo piglets in both control and treatment groups. The BCR of LWY pigs was more when compared to that of Ghungroo pigs in both control and treatment groups. It was also observed that BCR for both Ghungroo and LWY piglets was more in control groups in comparison with treatment groups. Conclusion: Thus, it can be concluded that attainment of feasible body weight was not possible by only feeding locally available cooked feeds to Ghungroo and LWY piglets and so, piglets should be offered balanced ration for a profitable pig farming.

The results of statistical analysis showed that the treatment had a significant effect of P<0.05 on crude protein, non nitrogen free extract, energy content, but had no significant effect of P>0.05 on crude fiber content. The conclusion of this research is that the addition of fermented Moringa leaf extract and Azadirachta indica liquid to local pig rations has an effect on increasing protein and energy content with an average increase in protein content of 3.36% and energy of 107.73 kcal. for each increase, add 250 ml of liquid Moringa leaf extract and fermented Azadirachta indica to the local ration.

Effect of Dietary Substitution of Wheat Bran with Dried Brewer’s Spent Grains on Performance and Economics of Growing Crossbred Pigs

Background: Brewers spent grains (BSG), may offer a suitable cheap replacer for traditional feedstuffs. The present study investigated the effect of dietary substitution of wheat bran with BSG on performances and production economics of crossbred grower pigs . Methods: The current study was conducted on sixty crossbred pigs (28 male + 32 female) that were randomly divided into four groups and allotted to dietary treatment replacement by 0% (T0), 25% (T1), 50% (T2) and 100% (T3) dried BSG against conventional wheat bran in pig ration. Results: Results indicated significant (P less than 0.05) improvement in the total body weight gain and average daily gain (ADG) in both male and female crossbred pigs in groups T0, T1 and T2 when compared against T3. The performances of the both female and male pigs were significantly (P less than 0.05) lower when dietary levels of BSG were increased up to 100 % (T3). Group T3 had significantly (P less than 0.01) lower carcass traits as compared to the other groups. The feed cost/kg live weight gain in T2 was significantly (P less than 0.05) lower than the control group in both the sexes. In conclusion, crossbred pigs can tolerate up to 50% substitution of wheat bran with BSG and is cost-effective.

APPLICATION OF VERMIGHUMUS IN FEEDING PIGS

The article analyzes a new method of fattening young pigs by introducing a biologically active additive into the diet - vermighumus, which is a product of pig manure processing by California worms. In addition to the standard diet, the youngsters of the research groups consumed vermighumus in a dose of 130, 180, 230 g per head per day. The young of the control group consumed standard compound feed. It was established that the application of vermighumus into the diet of young pigs improved their fattening indicators. In particular, the youngsters of the second and third experimental groups exceeded the control analogues in terms of live weight at the end of fattening by 3.73 and 5.53%, respectively. Youngsters of the second and third experimental groups also had higher growth energy by 4.80 and 7.40%, respectively, and better feed payment (by 0.43 and 071 kg). In terms of half-carcass length, young animals of the experimental group 3 did not significantly exceed the counterparts of the control group. In the 2nd and 3rd experimental groups, the fat thickness at the level of the 6th-7th thoracic vertebra was smaller (by 5.85-7.50%). They prevailed over the control analogues in the area of the "muscle eye" (by 2.83-5.45%). The weight of the rear third half of the carcass and the content of meat in the carcass was the highest in young animals of the 3 experimental group (by 7.85% and 4.91%, respectively), and the fat content in it was lower than in the control group (by 14.52%). The smallest fat thickness at the level of the 6-7 thoracic vertebra, as well as the content of fat in the carcass, was in young animals of the third experimental group. Among the indicators of the physical and chemical properties of the muscle tissue of young pigs of the experimental groups, no statistically significant differences were found. However, there is a certain trend towards a decrease in such indicators as the level of acidity, tenderness and losses during cooking, and an increase in the moisture-holding capacity and intensity of coloring in the young of the control group. The tasting evaluation revealed minor differences among the experimental animals. The relative number of lymphocytes (% of the total number of leukocytes) in pigs treated with vermighumus was higher (by 4.44-6.66% Р<0.05) than in counterparts fed with conventional compound feed, which indicates an improvement in resistance animalsEnrichment of the ration of young pigs with vermihumus as a biologically active additive contributed to the improvement of fattening and meat qualities and ensures obtaining additional basic products in the amount of UAH 320.38-354.34 per head.

THE EFFECT OF USE OF CONCENTRATES BASED ON BROILER FARM WASTE IN RATIONS ON BODY WEIGHT LOSS AND DIGESTIVE ORGANS LANDRACE PIG


 
 
 This research was conducted with the aim of knowing the effect of using protein concentrate based on broiler farm waste (KPLA) in rations on weight loss and digestive organ weight. The research used a completely randomi- zed design (CRD) with three treatments and four replications. The treatment is, A: with the use of 0% KPLA, B: with the use of 12% KPLA and C: with the use of 24% KPLA. The research used 12 pigs finisher phase with an average body weight of 66.6 ± 7.74 kg. The research parameters were body weight loss, small intestine weight and length, large intestine weight, and spleen weight. The results of the research were, after fasting for 12 hours, with the use of 0% and 12% KPLA there was a loss of body weight of 2.4% and 1.8% (P>0.05). The use of 24% KPLA (C) can increase body weight loss by 6.2%, significantly higher compared to A. The use of 0% - 12% KPLA does not cause a significant difference in the weight and length of the small intestine (P> 0.05), but with 24% KPLA (C) significan- tly reduced the weight of the small intestine by 11.9% and 11.3% in the length of the small intestine (P<0.05). The use of 0% - 24% KPLA did not affect the weight of the large intestine and the weight of the spleen (P>0.05). The conclusion of this research was the use of KPLA up to 12% did not cause significant changes in the parameters of slaughter weight, weight loss, weight and length of the small intestine. It is recommended to use KPLA in landrace pig rations up to 12%.
 
 

The effectiveness of short-duration in-feed organic acid use in finisher pigs for Salmonella control at slaughter

Reducing the risk of Salmonella contaminated pork products entering the food chain is important for improving food safety. This study aimed to evaluate the effectiveness of the short-duration use of three acidified feed interventions in finisher pigs for reducing the faecal shedding, caecal carriage and carcase contamination of Salmonella at slaughter. We also investigated the presence of Salmonella in transportation vehicles and abattoir lairages used prior to slaughter. In a series of seven farm trials, two groups of pigs received either their normal ration (control), or a ration containing one of three organic acid products (intervention) for a four-week period before slaughter. Product A was trialled on five farms, and Products B and C were trialled on one farm each, included in the ration of intervention pigs at the manufacturers recommended rate. Faecal samples were collected and examined before and after the four-week intervention; caecal content samples and carcase swab samples were collected at slaughter. The lorry used to transport pigs to slaughter and abattoir lairage pens used to hold pigs were also sampled. During one trial (farm ID: AT03), no Salmonella was detected during either farm visit, and therefore this farm was excluded from further analysis of the effectiveness of organic acid interventions. Overall regression analysis indicated there was no significant difference in faecal shedding between the control groups at the baseline visit and the follow-up visit in pigs which received Product A (P = 0.262) or Product B (P = 0.094) in comparison to the control groups. On the other hand, there was evidence to suggest that the use of Product C was associated with an increase in faecal shedding compared to the control groups (P < 0.001). Similarly, Product A was not significantly associated (P > 0.05) with the caecal carriage of Salmonella. However, Product B (P = 0.029) and Product C (P = 0.050) were associated with an increase in caecal carriage in comparison to the control groups. These latter products were only trialled on one farm each, and these results may be attributable to natural random variation.

МОДЕРНІЗАЦІЯ МАЛИХ СВИНОФЕРМ ІЗ ЗАМКНУТИМ ЦИКЛОМ ВИРОБНИЦТВА ПРОДУКЦІЇ

The purpose of the research is to assess the relevance of modernization of small pig farms with a closed production cycle. Research methods. Analytical research on the relevance of modernization of small pig farms with a closed production cycle was carried out by the method of processing existing scientific and informational reports. Research results. When organizing pork production at the farm level, the most important measures should be on the production flow, formation of homogeneous technological groups of pigs, herd reproduction, sow keeping, quality of feed rations, creating a proper microclimate, compliance with production technology. One of the main factors holding back the growth of pork production is the lack of feed, their low quality and the constant shortage of digestible protein in feed rations for pigs. The existing premises of small pig farms do not fully meet modern requirements for the maintenance of various technological groups of pigs. The further development of pig farming requires important issues related to sanitary protection zones, animal welfare and environmental protection. It is important to ensure biosafety in pig farming and to implement appropriate veterinary practices and standards. In most pork farms, the genetic potential of domestic pig breeds is now used for reproductive qualities by only 45-50 %, and for fattening by 20-25 %. In the system of qualitative improvement of the breeding stock of farms, the disadvantage is the unsystematic use of reared young pigs, 70% of the products are sold to meat processing plants. When modernizing small pig farms with a full cycle of pork production, among other things, it is necessary to take into account the size and resource characteristics of basic farms to achieve high efficiency of production. Conclusions. According to the results of analytical studies, for the first time the urgency of modernization of small pig farms with a closed production cycle was assessed. The constant shortage of digestible protein in feed rations for pigs is holding back the increase in pork production. Premises of small pig farms do not meet modern requirements for keeping different sex and age groups of pigs. In general, biosecurity and the implementation of good veterinary practices and standards are important in pig farming. There is a low level of realization of the genetic potential of domestic breeds of pigs. The disadvantage should be considered the unsystematic use of raised young. During the modernization of small pig farms, it is necessary to take into account the resource characteristics of farms to achieve high efficiency of pork production. Key words: production, small pig farms, modernization, modern requirements, pig breeding, pork.

Effect of Milk Thistle (Silybum marianum) Supplementation on Pork Offal Quality.

Simple SummaryDue to their natural origin and a wide range of positive effects on the body, herbs and spices are currently becoming commonly used as a nonantibiotic component of pig rations. There is research evidence to confirm health-promoting effects of milk thistle on humans and animals. The greatest effects are seen for the liver, i.e., protection from toxins and regeneration. The aim of the study was to determine the effect of adding milk thistle seeds on the quality of edible internal organs from the fatteners, which are used in food production as offal. We suggest that our study shows room for improvement of offal quality and may have a positive impact on consumer awareness in the context of offal consumption.The aim of the study was to determine the effect of milk thistle supplementation of fattener pig feeds on physical and chemical properties of pork offal. The experiments were conducted on 60 fatteners (group C—control (30 pigs) and group E—experimental (30 pigs)). The experimental group was supplemented with ground milk thistle (Silybum marianum) at 7 g/kg feed. The offal (tongues, kidneys, hearts, lungs and livers) was analyzed for weight, pH, WHC, water, protein, fat, energy value, fatty acid profile and content of major and trace elements. The present study shows that milk thistle added to fattener pig diets increased pH45 and pH24 values in most of the analyzed offal and significantly (p ≤ 0.01) decreased the weight of heart and lungs and increased the weight of liver and kidneys. Hearts, lungs and kidneys of the experimental group contained more fat and the liver less, than the same offal of the control group. As regards the content of elements, the dietary supplement most often had an effect on the heart and lungs. In general, milk thistle supplemented in fattener diets had modified the physical parameters and chemical composition of the analyzed products.

Digestible and metabolizable energy prediction models in guinea pig feedstuffs

ABSTRACT In the formulation of rations for guinea pigs, the energy value of the food and the requirements should be expressed as digestible energy (DE) or metabolizable energy (ME); the chemical composition tables do not report values for this species. The conventional determination of DE and ME of the feedstuffs requires animal experimentation, personnel, and specialized high-cost equipment. Study objective was developed mathematical models to estimate DE and ME using chemical composition and digestibility data from 26 forages, 8 dry agro-industrial wastes and 23 concentrated feeds, generated in previous studies using 5 male guinea pigs aged 5–6 months at 600–700 g of weight in each trial. Multiple hierarchical linear regression in SPSS 23 was used to generate the prediction models. Equations based on total digestible nutrient content served as standard equations for comparison with models generated based on . The best fitted equations for predicting ME content were those using DE ( = 0.966), and dry matter, crude protein, crude fiber, organic matter, and organic matter digestibility ( = 0.910). Other equations were generated to predict DE and ME of guinea pig feeds, using other proximal components and digestibility coefficients, with greater than 0.9.

Effects of Fermented Banana Stem as Corn Substitutes on Performance and Protein Utilization in Growing-Finishing Pigs

The objective of this study was to test banana stem silage as a substitute for corn on the performance and protein utilization rate of Duroc crosses pigs in the rearing phase. A total of 12 Duroc crosses pigs in the rearing phase with an average initial weight of 51.25 kg (KV = 7.02%). A completely randomized design (CRD) with 4 treatments and 3 replicates was used in this study. The treatments were T0: ration without a mixture of fermented banana stems (FBS), T1: ration with 5% FBS instead of cornmeal, T2: ration with 10% FBS instead of cornmeal, and T3: ration with 15% FBS instead of cornmeal. The variables measured were ration consumption, daily weight gain, ration utilization and protein utilization efficiency. The results showed that the use of FBS up to 15% (instead of 40% corn) had no effect on ration consumption, daily weight gain, ration utilization and protein utilization efficiency. Therefore, it can be concluded that banana stems can be used at 15% in the ration of Duroc crosses pigs in the rearing phase as a substitute for corn meal.

PENGARUH PEMBERIAN TEPUNG SAGU (Metroxylon SP) TERHADAP PERFORMANS TERNAK BABI RAS FASE GROWER

This study aims to determine the effect of adding sago flour (Metroxylon SP) in commercial rations on the performance of pigs in the grower phase. This study used an experimental method using a completely randomized design (CRD), which consisted of 4 treatments and 3 replications so as to obtain 12 experimental units. The research treatments were: R0 (commercial ration CP551 as control diet), R1 (95% commercial ration CP551 + 5% sago flour), R2 (90% commercial ration CP551 + 10% sago flour) and R3 (85% commercial ration CP551 + 15% sago flour). This study used 12 pigs, aged 3 months with an initial body weight range of 9.9 to 10.36 kg. Research feed was given for 6 weeks. The variables measured included average body weight gain (PBB), ration consumption, ration conversion. The results showed that the provision of sago flour in commercial rations on body weight gain (0.908-1.083 kg/head/day), total consumption (2.075-2.083 kg/head/day) and ration conversion (1.944-2.287 kg/head/day) did not significant effect (P&gt;0.05). The use of sago flour in commercial rations for pigs in the grower phase can provide good growth even though body weight gain, total consumption and ration conversion remain the same.

Carcass Composition and Quality of Meat of Pulawska and Pulawska x PLW Crossbred Pigs Fed Rations with Naked Oats.

Simple SummaryDue to the presence of fibrous hulls, the use of traditional cultivars of oats (Avena sativa L.) in feed rations for pigs is restricted. The development of naked oat cultivars (Avena nuda L.) containing only about 2% of crude fibre allowed this cereal grain to be included in the diets of monogastric animals. The present studies evaluated the efficiency of a 60% inclusion of naked oats in rations fed to Pulawska pigs and Pulawska x Polish Large White (PLW) crossbreds on their performance results (weight gain, feed conversion), carcass composition and physical (pH, colour, WHC) and chemical (essential nutrients, fatty acids) characteristics of meat. It was demonstrated that a 60% inclusion of naked oats is recommended in the diets of Pulawska pigs and Pulawska x PLW crossbreds to maintain carcass composition and meat quality comparable to that of pigs fed with rations containing barley only. The performance indicators of Pulawska pigs declined, but their meat quality traits improved in terms of nutritional value, as the n-6/n-3 acids’ ratio was narrower than that of Pulawska x PLW.The study aimed to determine the impact of a 60% inclusion of naked oats in feed rations for Pulawska pigs and Pulawska x Polish Large White (PLW) crossbreds on the fattening performance, carcass composition, and meat quality. It was demonstrated that—independent from their diet—Pulawska pigs showed a daily weight gain about 14.5% lower (p ≤ 0.05), with about 15% higher feed conversion rate. The experimental factors showed no impact on the dressing percentage, meatiness, and backfat thickness, except that the “eye” of the loin was significantly smaller (by 4.55 cm2) in Pulawska pigs. There was no interaction effect (diet/breed) for the pigs’ performance results and carcass composition. A 60% inclusion of naked oats in the pigs’ diet did not affect the weight of primal cuts in the right-side half-carcass. Compared to Pulawska pigs, crossbreds featured a significantly lower weight of bacon and ribs (by 1.17 kg) but a higher (p ≤ 0.05) weight of fillet (by 1.0 kg) and ham with shin (by 0.43 kg). The diet had no impact on the evaluated muscles, except a reduction (by 2.3 points) in colour lightness (L) of musculus semimembranosus in fattening pigs receiving feed rations with a 60% share of oats. Both muscles in Pulawska pigs showed significantly better (p ≤ 0.05) water-holding capacity and reduced colour lightness (L) in comparison to crossbred pigs. Moreover, the longissimus lumborum muscle of Pulawska pigs had a higher chroma (C) and a lower hue (H). The contents of essential nutrients in the evaluated muscles did not depend on the pigs’ diet and breed, except that a higher by 0.3% (p ≤ 0.05) intramuscular fat content was found in the longissimus lumborum muscle of Pulawska pigs. Neither of the experimental factors showed significant impact on the total saturated fatty acids (SFA) and total unsaturated fatty acids (UFA), or on neutral or hypocholesterolemic (DFA) and hypercholesterolemic fatty acids (OFA) in the evaluated muscles. The muscles of Pulawska x PLW pigs contained more (by 1.77% FA in the longissimus lumborum and 1.16% in the semimembranosus) polyunsaturated fatty acids (PUFA) than the muscles of the Pulawska breed (p ≤ 0.05). In addition, naked oats included in the pigs’ diet increased (p ≤ 0.05) the share of PUFA in intramuscular fat. The muscles of Pulawska pigs, in comparison to the muscles of crossbreds, showed a significantly improved ratio: by 66% and 69% in the longissimus lumborum and the semimembranosus muscles, respectively. To sum up, a 60% inclusion of naked oats is recommended in the rations of both Pulawska pigs and Pulawska x PLW crossbreds, since it allows satisfactory carcass composition and meat quality to be maintained. Pulawska pigs had worse productivity ratios but showed improved meat quality traits in terms of the n-6/n-3 ratio.

Effect of alpha-monolaurin on perfomance of fattening pigs under industrial conditions

Relevance. Monoglycerides of organic acids are considered as a promising replacement for feed antibiotics in the diets of pigs and poultry, as they have pronounced bacteriostatic and bactericidal properties. Alpha-monolaurin is a one of the most promising compound, which has a significant antibacterial effect on gram-positive microorganisms.Methods. The experiment was carried out at one of the pig farms of the Rostov region on September 5–27, 2020 on fattening pigs weighing from 36 kg and up to achievinga live weight of 75 kg. Piglets of the experimental group received 0.4 kg/t of alpha-monolaurin as part of the premix for compound feed CK-5. In the conditions of the production site, control weighing was carried out before the beginning and at the end of the experiment. Weight gain, feed consumption, survival rate and feed conversion were recorded.Results. The possibility of using alpha-monoglyceride lauric acid (GML, glycerol monolaurate) in the ration of pigs of the first period of fattening under the industrial conditions of an operating pig farm has been studied. It has been found that alphamonolaurin improves feed conversion, reduces feed intake, and also increases the survival rate of fattening pigs.

A descriptive chemical analysis of seaweeds, Ulva sp., Saccharina latissima and Ascophyllum nodosum harvested from Danish and Icelandic waters

This study aimed to discuss the chemical composition of three seaweed species commonly found in Nordic countries and its potential use in feed rations for pigs and calves. Two brown seaweeds Ascophyllum nodosum, Saccharina lastissima and a green seaweed Ulva sp. harvested from Danish and Icelandic waters were analyzed for proximate, amino acids, minerals, fatty acids and non-starch polysaccharides composition. All studied seaweeds contained low protein concentrations (i.e. 11.4–15.9 g/100 g DM). The ratio of essential amino acids (EAA) to non-essential amino acids (NEAA) was similar in all studied seaweeds (0.81−0.87). Ulva sp. had the highest ash concentration (48.2–54.4 g/100 g DM), followed by S. latissima (39.9 g/100 g DM) and A. nodosum (29.5 g/100 g DM). The most abundant macrominerals in the seaweeds were Ca, K and Na. Iodine was the most abundant micromineral in brown seaweeds (1.4–2.1 g/kg DM). Moreover, Ulva sp. had the highest Fe (5.1–8.0 g/kg DM), Mn (10.5 g/kg DM) and inorganic As (0.008 g/kg DM) concentrations. Ascophyllum nodosum had the highest crude fat concentration (3 g/100 g DM) and the highest concentration of polyunsaturated fatty acids (FAs) (37.9 g/100 g FA). Eicosapentaenoic acid (EPA) concentration was the highest in A. nodosum (7 g/100 g FA) followed by S. latissima (5 g/100 g FA) and Ulva sp. (2 g/100 g FA). Furthermore, concentration of α-linolenic acid, a precursor for EPA, was the highest in Ulva sp. (6.2–14.6 g/100 g FA). Total dietary fiber concentration was higher in the brown seaweeds (27.8–42.6 g/100 g DM) compared to the green seaweeds (17.9–21.5 g/100 g DM), where S. latissima had the highest soluble dietary fiber concentration. The high concentrations of ash and fiber may limit inclusion levels of the analyzed whole seaweeds in feed rations, mainly due to dilution of other nutrients in the feed, reduced digestibility of the feed and possible toxicities (i.e. high inorganic As). On the other hand, high concentrations of essential and valuable microminerals including I, Cu, Fe, Mn, Se were also detected in the studied seaweeds. High soluble dietary fiber concentration in S. latissima can be of interest as a fermentable substrate for probiotic bacteria. The easily digestible nutrients including, crude protein and fat were low in the seaweeds. However, the protein, fat, ash and dietary fiber fractions of the studied seaweeds were characterized by high concentrations of EAA, EFA, essential microminerals and interesting monomers of functional polysaccharides, respectively; which indicate possibilities for future use of seaweed-extracts in feed rations.

МОРФО-БИОХИМИЧЕСКИЙ СТАТУС МОЛОДНЯКА СВИНЕЙ НА ОТКОРМЕ ПРИ ИСПОЛЬЗОВАНИИ В ИХ РАЦИОНАХ КОРМОВЫХ ДОБАВОК «ПОЛИСОЛ ОМЕГА-3» И «ОМЕГА-3 АКТИВ»

The article describes results of application of «Polysol Omega-3» and «Omega-3 Active» feed additives in rations of young pigs during fattening period and their influence on hematological and biochemical parameters of animals‘ blood. The research was carried out at the pig breeding complex SPK named after N.K. Krupskaya of Melekesskyi district of Ulyanovsk region. The basis of «Omega-3 Active» supplement is flaxseed oil, which contains 60% of polyunsaturated fatty acids and the prevailing proportion of Omega-3. The feed mixture «Polysol Omega-3» includes fatty acids in combination with a complex of biologically active and mineral substances. In addition to studying the productivity and quality of pig production, the study of the effect of these additives on morpho- biochemical status of blood and, in particular, lipid metabolism is of scientific interest. The results of the analysis showed that in case of application of these feed additives in the rations of young pigs, the concentration of erythrocytes in their blood was higher in comparison with control analogs by 1.13 ... 3.56 %, hemoglobin by 7.97 ... 14.15 % (P &lt;0.01), the total protein content by 6 , 75 ... 7.88 %. This is confirmed by improvement of redox processes and metabolism in their bodies. The ration enrichment with the analyzed additives contributed to better usage of fats in feed, which is confirmed by the studied parametres of lipid metabolism (cholesterol, HDL, LDL, triglycerides). The activation of biosynthetic processes had a positive effect on average daily gain of pigs, as a result of which the early maturity of animals increased by 9 ... 23 days

EFFECT OF PART SUBSTITUTION OF DIET WITH LEAF AND STEM OF SWEET POTATO MEAL ON DIGESTIBILITY OF CALCIUM AND PHOSPHOR IN PIG.This study aims to find out the extent of the influence of the use of leaf and stem of sweet potato meal replacing some of the diet on calcium and phosphor consumption and digestibility in pig. This study used the design of latin square (Latin Squere Design) 5 x 5 consisting of 5 male pigs kastrasi results of the crossing Duroc X Spotted Polland China aged about 3.5 - 4.0 months, initial weight 50 kg (± 2.5 kg) and allocated into 5 treatments as follows: R0 = 100% basal diet + 0% leaves and stems of sweet potato; R1 = 92.5% basal diet + 75% sweet potato leaves and stems; R2 = 85% basal diet + 15% leaves and stems of sweet Potatoes, R3 = 77.5% basal diet + 22.5% leaves and stems of sweet potatoes; R4= 70% basal diet + 30% leaves and stems of sweet potatoes.The parameters measured were: the consumption of calcium and phosphorus, as well as theingest of calcium and phosphor. The results showed that the average calcium consumption of pigs in the initial phase of the finisher in each treatment ranged from 10.88 - 13.60grams, and for the average consumption of phosphorus ranged from 10.74% - 13.42grams.While the calcium ingest of pigs early phase finisher in each treatment ranges from 54.37 – 55.16% and for average of phosphor digestibility ranges from 62.27 – 61.23%.

In conclusion, The flour of leaf and stem sweet potato can replace up to 30% of the basic ration of pigs in the initial phase of finisher no negative effects on consumption of digestibility calcium and phosphor.Keywords: Leaves and stems of sweet potatoes, ingested calcium phosphorus, pig livestock

POULTRY OFFAL MEAL AS A PROTEIN SUPPLEMENT FOR GROWER PIGS

A 16-week feeding trial, involving 18 weaner pigs in a randomized complete block design, was carried out to determine the value of poultry offal meal (POM) as a protein supplement for grower pigs at three dietary levels, 0%, 10% and 20%. Liveweight gain, dressing percentage and backfat thickness were significantly (&lt;0.05) higher in pigs fed 20% POM dietary level. The cut parts, heart, liver and kidney, also increased with increasing level of POM), the diets. The poultry offal meal (POM), the processed, edible and inedible parts of poultry (viscera feathers, beaks blood, discarded eggs and dead birds) used for this study, contained 56.4% crude protein 20.9% crude fat, 7.7% total ash 4.6% crude fibre and 3.18Kcal/gin metabolizable energy. The results of this study suggest that POM could be incorporated in grower pig rations up to 20% with good results.
