EFFECT OF BENTONITE ON MEAT PRODUCTIVITY AND QUALITY OF PORK GILTS
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

ACTUAL PROBLEMS IN ORGANIZATION OF FEEDING IN MODERN CONDITIONS
06.00.00 Agricultural sciences
DescriptionModern pig farming is a leading global livestock industry, but the organization of adequate balanced feeding is actual for the industry. Digestibility of metabolizable energy of feed depends on various factors, including the content of non-starch polysaccharides, which have a negative effect on the digestibility of key nutrients of the feed, lead to a decrease in growth rate and conversion efficiency of nutrients. Enzyme preparations which composition generally includes Xylanase, cellulase, β-glucanase activities, may avoid the negative impact of non-starch polysaccharides. Today's promising preparation that combines the functions of two feed additives - feed enzyme and probiotic, is an enzyme preparation Cellobacterin that, due to the particular organization of the enzyme complex, increases the digestibility of barley grain and effectively effects on sunflower meal. As a probiotic preparation it inhibits the development of pathogenic microorganisms and promotes the formation of beneficial microflora in the digestive tract. The introduction of Cellobacterin enzyme preparation into the compound feed with a high content of barley grain and sunflower meal increases the body weight of young pigs by 4.8% and reduces the cost of feed per 1 kg of live weight gain. The results of hematological studies found no significant deviations from the physiological norm in the morphological picture of the blood in experimental animals. The group, where Cellobacterin was added, showed higher vitamin A content by 2.8% as compared to the control, while vitamin E is found in both groups on the same level. Based on the results of the research to improve the productivity and growth rate in compound feed based on barley and sunflower meal with higher fiber content, it is recommended to include in the compound feed Cellobacterin enzyme preparation at the rate of 1 kg per 1 ton of feed
