EFFICIENCY OF USE OF THE METALACTIM FEED ADDITIVE WHEN RAISING YOUNG CATTLE

As a result of studying the effectiveness of using the Metalactim feed additive in growing young cattle it was established that the studied feed additive has a positive effect on the morphological composition of blood, promotes the activation of protein metabolism, increases the natural resistance of animals, reduces the content of urea by 19,2% (P<0,01), as well as cholesterol by 24,1% (P<0,01), respectively, this indicates the activation of metabolic processes in the body, normalization of the functional state of the liver (deaminating function) and kidneys (ability to excrete nitrogen metabolism products), increased assimilation of minerals, as well as more efficient use of nitrogen coming with feed. The use of feed additive in calf diets also promotes the stimulation of animal growth – increase in live weight by 3.2%, average daily gain by 15.1% (P<0.01), and relative live weight gain – by 9.52 p.p. in comparison with the control, respectively.
