Abstract
Currently, the country’s industrial pig breeding uses mainly imported granulated compound feed and expensive enrichment additives containing protein products with different processing technologies, and biologically active substances. This leads to an increase in the cost of pig products. Alternative to imported analogues complex enrichment additive for prestarter feed from domestic raw materials has been developed, the use of which has been scientifically justified. The basis of this additive is soya and lupin with different processing methods, corn gluten, fish meal and milk whey, as well as biologically active substances. Optimal modes of extrusion of soya, fl ax seeds, grain feed, processing additives and granulated feed under the conditions of the feed mill have been worked out. Tests of granulated compound feeds with experimental and imported processing additives on piglets of suckling age have been carried out at the pig breeding complex. It has been established that the qualitative characteristics of the granulated compound feed with additives and processing subjects were almost equal. As the result of their use on the large number of pigs, high livability of off spring was ensured and almost equal indicators of live weight of young animals at 24-day age were obtained at the level of 253–254 g. At the same time, the level of hemoglobin in the blood was high at 119,7–120,6 g/l, and the young animals of the experimental group had the advantage in the content of γ-globulins by 1,92 %, which indicates the higher immune status of the animals of the experimental group. Studies have shown that granulated compound feed with the complex enrichment additive of domestic production is cheaper than imported by 29,76 %. This is economically beneficial for the farm.
