THE EFFECT OF FEED ADDITIVE ACID LAC DRY AND ITS COMBINATIONS WITH PROBIOTIC PROLAM ON THE PROCESS OF INTESTINAL MICROBIOCENOSIS FORMATION IN CALVES WITH HYPOTROPHY

The article represents the data on studying the effect of feed additive Acid Lac Dry, probiotic Prolam and their complex application to calves with hypotrophy during colostral period on intestinal microbiocenosis formation. Researches were carried out on 32 newborn calves with hypotrophy of Holstein-Frisian rocks, which formed 4 groups (n=8). The drugs were not used for the animals of the 1st (control) group. Calves of experimental groups were prescribed orally in the 1st week of life: Asid Lak Dry 15,0 gramms as an aqueous suspension (group 2), probiotic Prolam with colostrum (milk) 5...7 cm3 (3rd group), Asid Lak Dry in combination with Prolam at indicated doses (4th group). The 1st day the preparations were prescribed after the colostrum had been drunk, and Asid Lak Dry – in the following days. During the period of application of the feed additive and probiotics, antimicrobials drugs were not prescribed. A positive effect of both preparations and especially their combination on normobiosis formation is demonstrated. This significantly prophylaxed gastrointestinal diseases of animals and decreased the duration of their treatment under their emergence.
