Use Effect of Unconventional Feed and Mineral Additives on Animal and Poultry Productivity

Abstract

The possibilities of increasing productivity of animals and poultry by using an additive containing selenium, rapeseed cake and complex mineral additive have been studied. An addition of the preparation “Kartsesel” in mixed fodder promoted the increase in digestibility of nutrients, the increase in erythrocytes, hemoglobin in blood, output of conditioned youngsters, profitability of production. Conditioned young growth was obtained more by 19-22 %. Inclusion in mixed fodder at cultivation of goose rapeseed presscake of Siberian selection positively affected the increase of live weight, yield of gutted carcass. Goose of the first experimental group surpassed the control group by live weight by 3.4%, and the second experimental group by 6.1%. Output of gutted carcass of goose receiving rapeseed meal and rapeseed meal in combination with rapeseed oil is 286.13 g and 388.48 g more. Complex mineral additive in the diet of bulls contributed to the increase of live weight of bulls in 15 months of age, slaughter output, profitability of production and improvement of meat quality. The live weight of the control group of bulls not receiving the feed additive made 459.50 kg, and the experimental group made 11.00 kg more. At the same time the level of profitability of production on steers of the experimental group receiving a mineral additive amounted to 13.77% instead of 10.24% in the control group.
