ПРОБИОТИК "БАСУЛИФОР-С" В КОРМЛЕНИИ ТЕЛЯТ В МОЛОЧНЫЙ ПЕРИОД

Abstract

Relevance and methods. Currently, beef production is mainly developing on the breeding of black-motley breed of the cattle in agricultural organizations with a small plume of livestock. The increasing of calves’ productivity in the early period of growing in the farms requires the use of various biological active substances, which include probiotics. Feeding of different doses of probiotic Basulifor-C. Results. The addition of 15 and 20 g of probiotic per day to the diet for experimental calf groups per head allowed obtaining an average daily live weight gain of 8.5 and 19.3% more than in the control. The costs of exchange energy per 1 kg of gain were lower in the experimental groups, respectively by 7.9 and 16.2%. The analysis of the morphological and biochemical parameters of the calves’ blood at the end of the experiment showed that in the calves’ blood of the experimental groups there was an increase in leukocytes in the second experimental group by 2.1 and in the third by - 3.1%, hemoglobin in the third group was greater by 3.1, total protein by 2.9% in relation to control. A noticeable increase in the protein fraction in the blood of albumin calves; it was 6.7% more in the second experimental group.
