Influence of vitamin A as a synthetic preparation “Microvit” on the digestibility of basic nutrients of fodder by bull-calves at their feeding with the use of fragrance granules
Keyword(s):
They are given data of physiological action of vitamin A in different doses (in the form of its supplement - the pharmacological preparation “Microvit”) when introduced into diets with dry pulp on the digestibility of the main nutrients of fodder by bull-calves in the middle of the feeding cycle. The optimal dose of vitamin A was established. It is 230 IU per 1 head per day, which is 20% more than the recommended norm calculated for carotene. In this case, the digestibility of dry matter significantly increases by 3.3%, of organic one - by 2.7%, protein - by 3.0%, fiber - by 3.2%. There was also a slight tendency towards an increase in the digestibility of fat and nitrogen-free extractive substances by 1.8 and 3.0%, respectively.
