MEAT QUALITY OF DUCKS GROWN ON DIETS WITH DIFFERENT CONCENTRATIONS OF BENTO-CLAY
Description
Obtaining maximum productivity and reducing production costs are the main challenges facing livestock producers in modern conditions. To achieve the effectiveness of the poultry industry, we carried out a research in the utilities sector of the Rostov Region, the purpose of which was to study the effectiveness of the use of a feed additive – bento-clay in the diet of ducklings grown for meat. In the research, we study the influence of various doses of the feed on the diet and growth of ducklings. Experimental research data showed that the introduction of bento-clay into the diet of ducklings as a feed additive allowed to increase live weight, average daily gain, the safety of ducklings, the mass of half-gutted and gutted carcasses, the yield of edible parts, and meat quality compared to the control group. Thus, bento-clay influenced the increase in the water-holding ability of ducklings meat, which contributed to the improvement of its technological properties. Therefore, at three weeks of age, the live weight of ducklings was 11.5% -18.2% more than ducklings of the control group, and at seven weeks of age this difference was 8.4-12%, respectively, and the average daily increase was 7.2 -14.1% with high safety

COMPATIBILITY OF VARIOUS DOSES OF ECOVENTURA AND LIMESTONE IN FEEDING OF REPLACEMENT YOUNG DUCKS
06.00.00 Agricultural sciences
Description
The research is aimed at studying the compatibility of different doses of ecoventura (TU 9283-199- 10514645-13) and limestone in the diets of rearing of ducks of "Blagovarsky" cross and the impact on productive performance. As a result of scientific and economic experience obtained data on the dynamics of live weight in groups of rearing ducks indicate that ecomentors in combination with limestone have a growth promoting effect and a positive effect on the growth of ducklings. Best growth depending on dose administration of ecoventura and limestone in feed composition had a rearing ducks III (ecomentors (1,0%) + limestone (3,0%) by weight of the feed) and IV experimental groups (ecomentors (1,0%) + limestone (3,5%) by weight of the feed). The results of the study measurements (body length, keel length, breast width, chest girth, chest depth) and indices stature (massiveness, the meat content, arizonia), which were higher in males and females when fed with mixed fodder with the introduction of ecoventura and limestone in an amount of 1.0 and 3.5% respectively. Introduction to feed composition of ecoventura and limestone in an amount of 1.0 and 3.5%, respectively had a positive impact on exterior indicators of rearing ducks
