The trend towards an increase in ethanol production on a global scale and the tightening of restrictive measures regarding the disposal of by-products from production increases the relevance of research in finding ways to process them. This study aimed to assess the effectiveness of a feed additive containing dried stillage fermented with pre-immobilized cultures of Lactobacillus pontis 67, Lb. casei 22, Lb. paracasei 104 when finishing steers. The dose of inoculum (3.0%) of a liquid probiotic drug based on the consortium Lb. pontis 67, Lb. casei 22, Lb. paracasei 104 was determined, cultivation time 24-30 hours at a bacterial titer of 10-10 CFU/ml, and the characteristics of fermented stillage and a feed additive based on it were established. Studies were conducted to assess the effectiveness of finishing when using fermented wheat stillage on the qualitative characteristics of the carcass of 13-month-old Kazakh white-headed steers on finishing. The studies were conducted in 2 groups: control and experimental (13% fermented stillage). The experimental group showed higher indicators of average daily gain (Р |
