The study determined the production performance and meat quality of broilers using different kinds and levels of bio-organic supplements. Four hundred fifty broiler chicks were randomly distributed to fifteen dietary treatments. Five birds in each treatment were used for meat quality evaluation following a 3 x 5 factorial in Completely Randomized Design (CRD). No significant differences were observed in the production performance of broilers supplemented with different kinds of bio-organic fertilizers except average daily gain and final live weight. Broilers supplemented with higher levels of bio-organic supplements including antibiotic significantly affected the production performance except for average daily water intake and dressing percentage. Feed cost per kilogram of broiler produced, feed cost per average daily gain and return above feed, chicks and supplement costs were not significantly affected by the different kinds of bio-organic supplements but significantly affected by the different levels of bio-organic supplements. Meat quality was significantly affected by the different kinds of bioorganic supplements except for taste and overall acceptability but was not significantly affected by increasing the levels of bio-organic supplements including those broilers supplemented with antibiotics in the drinking water. Better production performance was observed on broilers supplemented with different kinds and levels of bio-organic supplements in the drinking water but did not affect the meat quality.

The use of nanomaterials in poultry farming has become increasingly popular as feed additives capable of increasing the productivity of the herd. Nanocrystalline cerium dioxide belongs to nanomaterials with a broad spectrum of activity. Owing to their oxygen non-stoichiometry and low toxicity, cerium dioxide nanoparticles are a very promising object for agriculture. The paper presents the results of studying the meat productivity of quails of the Pharaoh breed when drinking nanocrystalline cerium dioxide in the composition of the feed additive “Nanocerium”. The study was carried out on quails during the rearing period from 14 to 49 days. For the experiment, two groups (control and experimental) of 24 heads each were formed from one day old poultry. The quails were kept in a vivarium, in cage batteries, subject to the accepted microclimate conditions. Poultry of both groups received compound feed, developed taking into account age and physiological characteristics. With drinking water, the of the experimental group additionally received nanocrystalline cerium dioxide as part of the feed additive “Nanocerium” at a dose of 8,6 mg per liter of water for 35 days. The quail population was counted and weighed weekly, starting from the day-old age. The following indicators were determined: safety, dynamics of live weight, average daily gain in live weight. According to the results of the control slaughter and anatomical cutting, the weight of the carcass and the weight of the edible part were determined. Slaughter qualities and morphological composition of quail carcasses were determined by anatomical cutting with the measurement of the following parameters: pre-slaughter weight, half-battered carcass weight, carcass patrana, slaughter yield, weight of edible parts. Drinking the feed additive “Nanocerium” by young quails increased their safety by 4.17%, live weight and absolute average daily gain by 20.3 g and 0.48 g (P <0.05), respectively. The addition of NDC quails to drinking water contributed to an increase in their pre-slaughter weight by 19.3 g, half-gutted carcass by 18.0 g, and gutted by 17.5 g in comparison with the control group. The quail carcasses of the experimental group had a higher yield of edible parts in comparison with the poultry that consumed pure water. Key words: quail, nanocrystalline cerium dioxide, safety, body mass, gain, slaughter rates, output of edible part.

The degree to which growth patterns are modified after a period of food restriction affects the compositional changes of the carcasses(Carstens et al., 1992), furthermore, the growth rate has a direct effect on the physical properties of meat (Fishell et al., 1985). The objective of this experiment was to evaluate the effects of a severe food restriction at a early stage of maturity on the slaughter characteristics and meat quality of Belgian Blue bulls.Twelve Belgian Blue bulls (dual purpose type) weighing 233 kg were offered two different planes of nutrition during the growing period. Six bulls (Group-) received a restricted diet so that their average daily gain was 0.34 kg/d (Group+) during 202 days. By contrast six other bulls were given a more conventional growing diet and their average daily gain was 1.13 kg/d. Both Groups were fattened with similar diet and slaughtered when the live weight was close to 600 kg. Carcass weight was measured and killing-out proportion calculated, the composition of the carcass was estimated after dissection of ribs 7, 8, 9 removed 48 h post-mortem.

The introduction of «Yantovet» into the diet of rabbits at a dose of 0,33 ml per 1 kg of live weight has a stimulating effect on the intensity of their growth and productivity. By the end of the experiment, the live weight of the experimental group was higher than that of the control by 13 %. The average daily gain for the entire period of experiments in the experimental group exceeded the same indicator in the control by 38,7 %. The rabbits of the experimental group had a higher level of productivity, as the slaughter weight and slaughter yield of rabbit carcasses in the experimental group in relation to the control group were higher by 16,6 and 2,9 %. The study drug is recom-mended to be used in the diet of rabbits in the composition of drinking water.

The aim of this experiment was to evaluate the effect of different fattening systems from pasture to concentrate and temperament on animal welfare (AW) and meat quality (MQ). Eighty-four Hereford steers were randomly assigned to the following groups: T1, pasture (4% of animal live weight: LW); T2, pasture (3% LW) plus concentrate (0.6% LW); T3, pasture (3% LW) plus concentrate (1.2% LW); T4, an ad libitum concentrate treatment. Temperament was assessed by three individual tests: crush score, flight time, and exit speed, building a multicriterial temperament index (TIndex). The flight zone was also registered for each treatment. AW was assessed through the integration of indicators of productivity, physiology, and behavior, as well as by monitoring the health status within each treatment. Shear force was registered for MQ. Differences in average daily gain were due to the different energetic composition of the diets (T4 > T3 > T2 > T1) and were not attributable to animal welfare problems. Animals from T4 had the higher average daily gain (ADG) but welfare was negatively affected, being evident through physiological indicators, the restriction or deprivation of relevant behaviors, diet-related diseases, and mortality. T1, T2, and T3 did not appear to compromise animal welfare. However, strict preventive measures and monitoring should be taken during the habituation process and when using any new diet that includes concentrate, because of possible dietary diseases. Shear force values were lower in T1. None of the animals in our experiment were excitable or aggressive, but there was a positive response to handling in all treatments. In addition, regardless of diet, calmer animals had higher average daily gain and lower shear force values; thus, temperament appears to have a significant influence on productivity and meat quality.

An economics experiment to study the values of Income over Feed Cost at various market prices of fattening sheep has been done at Sheep Experimental House of The Faculty of Animal Husbandry, UniversitasPadjadjaran. About 63 heads of Garut growing lambs were fattened for 90 days and fed by corn silage and concentrate. Feed consumption and average daily gain (ADG) were measured and Income over Feed Cost was analyzed at different selling prices: 40,000 IDR/kg live weight at general market, 60,000 IDR/ kg live weight at Aqiqah Market, and 80,000 IDR/kg live weight at Qurban Market. The result showed that ADG of lambs was 122 g/head/day resulting in selling prices of 4,882 IDR/head/day for general market, 7,323 IDR/head/day for Aqiqah market, and 9,764 IDR/head/day for Qurban market. If average feed cost was 3,508 IDR/head/day, its Income over Feed Cost was 1.374 IDR/head/day for general market, 3,825 IDR/head/day for Aqiqah market, and 6,256 IDR/head/day for Qurban market. At non-feed cost of 1,921 IDR, there was a potential loss of 547 IDR/head/day if selling price was only 40,000 IDR/kg live weight. Breakeven point could be reached at selling price of 44,500 IDR/kg live weight. It is concluded that fattened lambs is not profitably sold to general market but can be profitably sold to Aqiqah and Qurban markets.

The most perspective genotype in our region is Red White-belted breed, which has high performance both under pure breeding and under crossing with other breeds. The results of complex evaluation of Red White-belted swine of the herd bred in SE "RF Zoryane" breeding farm are presented. It was revealed that animals of the farm comply with elite class and the first class. The main breeding boars used at the farm belong to such genealogical lines: Deviz, Division, Dantist, Debut, and Dobryak. In the structure of the herd, the most numerous was Dobryak line, which part was 58.8%, Division, Debut, Devis lines – 11.8% per line, Dantist line – 5.8%. The herd sows belong to 7 families: Drabowka, Dekada, Dyktsiya, Doina, Dylema, Delta, Dogma. Average prolificacy of the sows was 10.0 piglets. Litter weight at 60 days’ age was 181.0 kg, and live weight of piglet – 19.0 kg. The performance of sows as prolificacy increased by 0.6 head on average. The complex appraisal index for the herd was 104.1 points. The average daily gain of the replacement pigs was 570 g. The highest daily gain was from five to six months – 611.2 g, and the figure of compactness index characterized a certain elongation of animals, increasing meat traits. Further work with Red White-belted breed aims at preserving and expanding the breeding base and genealogical structure, as well as increasing the reproductive, fattening and meat traits.

The objective of the study was to determine the effects of probiotic bacteria Bacillus licheniformis and Bacillus subtilis on microbiological properties of feed mixtures and on the digestive tract content as applicable to production traits and carcass characteristics of fatteners. The experiment was performed on 83,838 fatteners from four successive (insertions) productions in two groups. From the seventy eighth day of age till marketing to the slaughter plant, the pigs were supplied with BioPlus YC probiotic (Chr. Hansen) in the amount of 400 g/t. The preparation contained a complex of probiotic bacteria Bacillus licheniformis DSM 5749, and Bacillus subtilis DSM 5750 spores in a 1:1 ratio. From the fourth insertion, after reaching a body weight of approximately 112 kg, 60 fatteners were selected from each group to measure carcass quality and half of them for meat quality evaluation. Moreover, microbiological analyses in feed and colon were performed. The study showed that BioPlus YC probiotics supplementation resulted in a significantly higher count of B. subtilis and B. licheniformis in the feed, a higher count of B. subtilis, B. licheniformis and LAB, as well as a lower count of Enterobacteriaceae, Enterococcus, Clostridium and Bacillus sp. in the mucosa and in the colorectal content of the test pigs. Our work has shown that supplementation with the BioPlus YC probiotic had a positive effect on the production traits of pigs mainly by reducing mortality (2.83%, p = 0.010), lowering feed conversion ratio—FCR (2.59 kg/kg, p = 0.013), better average daily gain—ADG (0.95 kg/day, p = 0.002) and shorter fattening period (77.25 days, p = 0.019) when compared to the control group (4.19%; 2.79 kg/kg; 0.89 kg/day; 92.8 days, respectively). The addition of the specific Bacillus bacteria did not influence carcass and meat characteristics of the test fatteners.

AbstractA total of 384 piglets from a three-way cross Yorkshire ♂ × (Finnish Landrace ♂ × Dutch Landrace♀) ♀ in the live-weight range of 11 to 25 kg were used in a feeding trial. The effect of supplementary microbial phytase from Aspergillus niger var. Van Tieghem on performance (average daily gain (ADG), average daily food intake (ADFI) and food conversion ratio (FCR)) and apparent digestibility of total phosphorus (P), in comparison with a non-supplemented basal diet or a diet supplemented with one or two levels of monocalcium phosphate (MCP), were studied.The piglets were allotted to 12 blocks. Within each block, four experimental diets were offered ad libitum for a period of 4 weeks i.e. (1) basal diet; (2) basal diet + 1·0 g P, from MCP per kg diet; (3) basal diet + 1·9 g P, from MCP per kg diet; and (4) basal diet + 1450 phytase units (PTU) per kg diet. The diets, with added chromium III oxide as a marker, were cold pelleted without steam at a temperature not above 60°C to avoid a possible inactivation of the phytase. In all diets the ratio calcium: digestible P was intended to be constant.Adding 1450 PTU of Aspergillus niger phytase enhanced the apparent digestibility of P by proportionately 0·216 when compared with diet 1 and by proportionately 0·100 compared with diet 3. In addition, significantly higher ADG and ADFI and better FCR were noted in pigs receiving supplementary microbial phytase than in pigs on any other treatment. The content of digestible P of the diet with added phytase, however, zvas between the two levels of the diets with added MCP.

Sixteen blocks of eight littermate pigs were weaned at 3 weeks of age and each divided into four groups. Various levels of nutrition were applied to the pigs so that the four groups reached 20 kg. at 59, 68, 80 and 91 days of age, respectively.Only small differences were observed between groups in feed conversion ratio to 20 kg.; however, Group 4 required more feed per kg. gain than the three other groups.During the second period (20–90 kg.) the pigs in each group were divided into two sub-groups, which were on a high and a low plane of nutrition respectively. In both sub-groups the type of feeding before 20 kg. influenced the average daily gain and feed conversion ratio. The older the pigs were at 20 kg. the higher the daily gain and the lower the feed conversion ratio in the following period. There was an increase in daily feed intake with increased age at 20 kg. for pigs fed ad lib. during the second period.An increase in age at 20 kg. caused a significant decrease in thickness of backfat, a greater area of eye muscle and a smaller area of fat overlying muscle. For pigs fed ad lib. the area of eye muscle was significantly increased by a higher age at 20 kg. live-weight.

The purpose of the work was a comprehensive evaluation of the productive and reproductive traits of sows of Yorkshire and Landrace breeds and their offspring under the conditions of a breeding enterprise in the Republic of Belarus. During the studies of reproductive traits, it has been revealed that the highest rate of prolificacy among the evaluated breeds was distinguished by Yorkshire sows 14,0 heads for farrowing. In terms of milk content, Landrace sows were 2,5 kg or 4,57 % higher than Yorkshire sows. In terms of weight and socket weight per piglet at weaning at the age of 28 days sows Landrace piglets surpassed herdmates Yorkshire breed in the weight of the litter by 6,8 %, and the weight of one pig by 0,9 %. It has been found by the results of the evaluation of fattening and meat qualities of purebred young pigs that the best parameters were different gilts of Landrace breeds, whose age achieve the live weight of 100 kg was 163,1 days, and average daily gain of live weight – 864,8 g, which was higher than in young pigs of Yorkshire breed by 1,8 day or 1,09 %, and 28,9 g or by 3,46 %. The young pigs of Landrace breed has been characterized by the best values of the area of the “eye of loin” – 73,8 cm² and the highest yield and amount of meat – 68,5 % and 24 kg, which was 11,4 cm² or 18,2 % and 0,4 kg or 3,5 abs.%, respectively, higher than the herdmates of Yorkshire breed. The results obtained indicate the possibility of using boars and sows of Landrace and Yorkshire breeds not only in breeding, but also in industrial pig breeding.
