06.00.00 Agricultural sciences
DescriptionIn our country, great influence is given to the production and consumption of agricultural animals' meat with high consumer qualities. In this regard, the livestock producers, particularly pigs, are to increase production and improve product quality. Works on using some natural mineral complexes - bentonite and zeolites as a source of macro - and trace elements are performed. The aim of the research is to study the effects of bentonite feeding with free access on the meat productivity and hygienic meat quality of young pigs for fattening. Best effect on the slaughter indexes of fattening gilts had bentonite feeding with free access that resulted in significant superiority of the animals in the experimental group over the control counterparts on pre-slaughter live weight, slaughter weight, chilled carcass weight, slaughter yield, carcass length, the "muscle" eye area and the backgammon weight. More favorable effect in the longest muscle on the dry matter and protein synthesis was provided by bentonite feeding with free access. Due to this, the gilts of the experimental group were in significant advance of their control counterparts in concentration of dry matter and protein in meat. Along with this, the longest muscle of young pigs on fattening in the experimental group had the highest protein value, as according to the protein-qualitative indicator the animals of this group were in significant advance of the control counterparts. Feeding bentonite clay with free access had a strong detoxifying effect that is against control counterparts of gilts in the experimental group showed the significant reduce of lead, zinc and cadmium concentrations in the meat

06.00.00 Agricultural sciences
DescriptionIn this study we have shown the influence of fruitless shoots to number of berries in clusters, the mass of 100 berries, average weight of the bunch, yield, sugar content and acid in the juice of the berries, the quality of wine. These indicators have been studied at a ratio of fertile and sterile shoots 1: 1, 3: 1, 6: 1 with a load of bushes 12, 16, 20 fruit-bearing shoots and nutrition area 3 x 1 m2. Control was a natural balance of fruit-bearing and barren shoots. Digital material is processed by one-way analysis of variance experience for each load of bushes, and then the same method of two-experience for all the options. Fragmentation of sterile shoots with load of 12 fruit-bearing shoots per plant decreases, and with loads of 16 and 20 increases the number of fruit-bearing shoots berries in clusters, the mass of 100 berries, average weight of the bunch, yield, and sugar content in berries. For the content of titratable acids we have marked a tendency to increase with a decrease in the number of sterile shoots. The content of phenolic substances on the variants of the experiment was 2.2-2.3 g / dm3, the acidity of 7.3-7.8 g / dm3, alcohol 10,2-10,9% vol. Dry wines tasting score on the options was in the range of 7.4-7.6 points. Significant difference in taste and smell features wines by variants of the experiment was not revealed. Conclusions on the effect of sterile shoots on fruiting vine indicators drawn from the analysis of variance one- and two-factor experiments, in most cases were the same

DescriptionIn order to reduce the impact of stress factors on the body of pigs, new technologies and efficient veterinary and preventive measures in breeding and cultivation are being developed. The results of our scientific and economic experiments found that the use in daily diets of pregnant and lactating sows according to our schemes of biological additives (to finish / day.): Laktobifid (1 g), Immunobak (1 g), Provagen (10 g ) Vetom 1.1 (50 mg / kg body weight), Bacell (0.3% by weight of the feed) and Monosporin (10 mL), contributes to the improvement of their reproductive qualities: for twins - on 2,2-12,2% by krupnoplodnosti - by 8,0-10,7%, for milk - by 8,9- 36,5%, at the preservation of pigs - by 1,3-8,3%, by weight of the nest 2 months of age - 22 , 9-38,9% compared with the control. At weaning piglets from sows experimental groups indicators of natural resistance were significantly higher. The best reproductive performance were observed in sows treated with diet and probiotic supplements Immunobak Bacell combined with Monosporin . The results of these experiments revealed adaptogenic properties of the studied additives, their ability to mitigate the impacts of technological stresses, reducing as a result of the cost of the products. Of great practical importance is the ability to predict the effectiveness of the use of additives which have antistress effect, depending on the body weight of animals, their age, frequency and duration of their application before and after the impact of technological stressors in the suckling period, the periods of rearing and fattening up of live weight and 100 и 120 kg

THE INFLUENCE OF GENOTYPE OF RAMS ON THE QUALITATIVE CHARACTERISTICS OF MEAT
06.00.00 Agricultural sciences
DescriptionThe article presents the results of the qualitative assessment of meat of crossbred rams. The analysis of the data shows that crossbred rams of 2, 3 and 4 groups increased the absolute mass of muscle tissue compared with purebred 12.3; of 18.2 and 25.6%, respectively. Fine-wooled rams were superior in the relative content of bone in carcasses of crossbred 1.1- 4.2 percent. Output of pulp for 1 kg of bones had the advantage of crossbred rams 2, 3 and 4 groups compared with purebred 0.12; 0.24 percent and 0.44 kg respectively. The analysis of the data shows that in carcasses of young animals of all the groups the greatest specific weight took cuts of the 1st sort. Nevertheless, the valuable parts to carcass weight balance was higher in the carcasses of the crossbred calves. So, rams 2, 3 and 4 groups, this advantage was 1.9; 4.5 and 4.7%, respectively. Thus, the analysis of a complex of indicators characterizing the quality of meat rams of different genotypes revealed that the superiority for the studied indices took place for two - and three-bred animals. These options of both simple and complex industrial crossing are promising and can be implemented and used in the farms of Merino and crossbred sheep
