Growing efficiency of calves with the use of lactulose-containing additive

The most important period for feeding and keeping calves is colostrum and milk. Intensive growth and proper formation of the digestive system of young animals is the key to future productivity and reproductive abilities. In this regard, preparations of various biological nature are used to maintain the gastrointestinal microflora and assimilate the nutrients of feed. In our studies, the lactulose-containing supplement Vetelact was studied as an economically beneficial component of the diet, which contributes to an increase in the live weight of animals at different periods of growth. The results of the experiment showed that the live weight of calves of colostrum and milk periods at the end of the experiment was higher than in the control by 4.2% and 4.5%, while the profitability of production increased by 2.0% and 6.3%, respectively.
