ВЫРАЩИВАНИЕ ГУСЯТ НА МЯСО ПРИ ИСПОЛЬЗОВАНИИ КОРМОВОЙ ДОБАВКИ «БИО-МОС»

The article presents the results of a study of the effect of the Bio-Mos feed additive on the productive qualities of meat goslings of the white Hungarian breed. The work was carried out on the basis of Agro-Gus-Ural LLC in the Republic of Bashkortostan. Four groups of birds (control and three experimental) with 100 heads each were formed. The goslings of the control group received a basic diet, and Bio-Mos was added to the compound feed of the experimental groups in dosages of 0.4 g/kg, 0.6 g/kg and 0.8 g/kg, respectively. It was found that the introduction of the supplement had a positive effect on the growth and development of young animals. The greatest effect was observed in the second experimental group (a dose of 0.6 g/kg of mixed feed): by the 9th week, the live weight of males was 4649.6 g, which was 253.6 g higher than in the control group. A similar dynamic was observed in females. In addition, the second group recorded the best indicators of livestock safety (97% versus 91% in the control group). According to the results of the slaughter, the advantages of using the additive were also revealed: the yield of gutted carcass in the second group reached 63.0%, the weight of edible parts was 2189.5 g, which is 1.6% and 214.2 g higher than the control values, respectively. The ratio of muscle mass to bone mass improved to 2.5 versus 2.2 in the control. The calculation of economic efficiency showed that the use of Bio-Mos at a dose of 0.6 g/kg of compound feed provides the highest profitability (17.4%) by increasing safety, increasing live weight and improving meat qualities at optimal feeding costs. Thus, the use of Bio-Mos feed additive in the amount of 60 g per 100 kg of compound feed is scientifically justified and economically feasible to increase the productivity and profitability of raising goslings for meat.
