Abstract
The article presents comparative studies of the meat productivity of geese of the Lindovskaya breed when zeolite and nanostructured zeolite feed additives are introduced into their diets. It was shown that the use of zeolite contributed to an increase in the live weight of geese by 4.0 %, the use of different doses of nanostructured zeolite led to an increase by 6.2–10.2 % (P≤0.05), in comparison with control analogues. When using zeolite in meat, the content of zinc and copper salts decreased by 28.0 and 13.1 %. The introduction of nanostructured zeolite into the diet led to a decrease in zinc content by 27.5–31.3 % and that of copper by 27.1–48.6 % compared with the control. The meat of birds of all groups corresponded to hygienic quality requirements for the content of chemical elements.
Highlights
Increasing poultry production, improving quality and reducing its cost remains relevant at the present stage, as it allows you to solve issues of food safety.In recent years, increased demands have been made as for the quality of livestock products
Natural agrominerals – bentonites, zeolites, vermiculites, etc., whose deposits in a diverse composition and quantity are present in the Russian Federation and the Republic of Tatarstan — become unique substitutes for biogenic components in living organisms [1, 2]
The aim of the work was to study the effect of nanostructured zeolite in the form of a feed additive on the meat productivity and quality of goose meat
Summary
Increasing poultry production, improving quality and reducing its cost remains relevant at the present stage, as it allows you to solve issues of food safety. The consumer market dictates the need for livestock production without the use of chemical and synthetic drugs in the cultivation of animals and birds. In this case, natural agrominerals – bentonites, zeolites, vermiculites, etc., whose deposits in a diverse composition and quantity are present in the Russian Federation and the Republic of Tatarstan — become unique substitutes for biogenic components in living organisms [1, 2]. Methods of manufacturing nanostructured zeolites [18] are presented; the conditions for steric stabilization of zeolite nanoparticles [19] are shown In this context, the aim of the work was to study the effect of nanostructured zeolite in the form of a feed additive on the meat productivity and quality of goose meat
