MEAT QUALITY OF DUCKS GROWN ON DIETS WITH DIFFERENT CONCENTRATIONS OF BENTO-CLAY

abstract 1592005018 issue 159 pp. 268 – 279 29.05.2020 ru 144
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
