[Use of the colonizing preparation Amylastin in the stimulation of rumen-type digestion in young ruminants].

In experiments with calves during the milk-nutrition period we tested the use of the colonisation preparation Amylastim, containing a bacterial strain of Streptococcus bovis AO 24/85, as a factor speeding up the development of the rumen microflora. We gave the preparation to the animals for a period of four weeks and studied its influence on the microflora adherent to the epithelium of the rumen wall. We ascertained a significant increase in the number of Streptococcus bovis germs (P less than 0.001) as well as of alpha-amylase activity (P less than 0.05). When giving the preparation Amylastim to calves in large-scale production conditions we ascertained a positive effect on the health condition, total losses being lower.
