Experience of using the feed additive «Bonaka-APK-N» for young pigs

Abstract

Relevance. To improve and stabilize physiological processes in the body of pigs and increase immunity, the most affordable and optimal means of correcting the intestinal normoflora are the use of probiotics based on lactic acid bacteria in feeding.Methods. In the experiment, an environmentally safe technology was used for growing piglets of threebreed crossing (landrace x pietren x duroc). From the age of three weeks (21 days) to 3 months (90 days), the biotechnological feed additive «Bonaka-APK-N» was introduced into the diet of the 2nd and 3rd experimental groups, focused on optimizing the interior and productivity, at a dose of 0.5 ml/kg and 1.0 ml kg, respectively. M. (in 21–90 days). Subsequent fattening of pigs was carried out for up to 6 months (180 days) with the introduction of the additive «Bonaka-APK-N» into the diet of pigs of the 2nd and 3rd experimental groups at a dose of 1.0 ml /kg and 1.5 ml/ kg of fat, respectively. From the beginning of the experiment to the slaughter, the accounting period was 159 days. The slaughter was carried out at 6 months.Results. The use of an additive in the diet of pigs of the 2nd and 3rd experimental groups led to an increase in live weight gain compared with the control (1st group) by 16.7% and 15.3%, to an improvement in the physico-chemical parameters of pork, to an increase in the content of crude protein in muscle tissue compared with the control, respectively, by 2.8% and 1.7%; the protein quality index is significantly higher, respectively, by 23.6% and 16.4%. The analysis of the results of scientific and economic experience confirmed the efficiency of the use of the additive «Bonaka-APK-N» in the cultivation and fattening of young pigs for meat.
