Effectiveness of the using scheme for bactocellolaktin in prophylaxis of respiratory and gastrointestinal diseases in calves and weaned piglets
Abstract
The paper presents materials on the effect of probiotic bactocellolaktin (BCL) for the prevention of respiratory and gastrointestinal diseases in calves and weaned piglets. The experiments were conducted on two-month-old weaned piglets of Large White pigs and one-month- age calves of black-motley breed. The calves were distributed into 2 groups: control (20 goals) and test (40 goals). In the experimental group, BCL was administered orally at a dose 10.0 ml individually via syringe 1 times a day for a month. In the control, calves received a traditional diet without additives. Piglets were selected based on analogue: 100 goals both in test and control groups. In the test group, BCL inputted in the diet of pigs in the group by a dose of 5.0 ml per animal, 1 time a day for a month. The control pigs received a traditional diet without additives. Blood was investigated before and after the experiments: the number of erythrocytes, leukocytes and hemoglobin was estimated. After that, the animals were followed for an additional 30 days. Experiments carried out under industrial conditions in calves and weaned piglets had ahown that probiotic preparation BCL used at the recommended doses (10.0 ml for calves and 5.0 ml for piglets) in accordance with the proven scheme reduces the incidence of young cattle and pigs by 10-14%; and the effectiveness of prevention against respiratory and gastrointestinal diseases is within the range 90-98%. Thus maintaining in the test groups reaches 100%, whereas 90% - in control. The tested blood parameters were within normal limits.
