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

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
