Technological aspects of the use of complete granular all-mashes in the diet of rabbits

Abstract

To improve the nutritional value and digestibility in recipes of all-mashes the following feed additive was introduced: a paste of green mass of amaranth in doses of 10.0 and 15.0% and complex “Enzymesporin” - “Fungistat-GIC” (EF) at doses of 1.0 and 2.0 g/kg of all-mash, respectively. The studies of the effectiveness of complete granular all-mash were carried out on the livestock of young rabbits of the Soviet chinchilla breed at the age of 45 days, selected on the principle of groups - analogues and divided into 3 groups. The study was conducted in vivarium conditions of the VSAU in 2018. The control group of rabbits received a basic ration consisting of fodder PZK-92-60-18, rabbits of the experimental group received feed with the addition of the paste of green mass of amaranth and “Enzymesporin” - “Fungistat-GIC” (EF). Meat quality assessment was carried out at the age of 105 days after control slaughter in the amount of 3 heads from each group. It is established that rabbits of experimental groups digest nutrients of al-mashes better in comparison with control peers that further had positive influence on indicators of their meat productivity. The introduction of feed additives used in the al-mashes allowed increasing its digestibility by 8.5-10.0%, and also contributed to a higher transformation of feed nutrients into the protein component of muscle tissue.
