We have conducted an experiment aiming to identify the effects of the polyenzyme preparation Xybeten-cel on some fermentation processes in the rumen of buffalo calves. In the experiment we included five male buffalo calves of the Bulgarian Murrah breed, aged fifteen months, with the average liveweight of 320 kg. All experimental animals were fistulated on the dorsal sac of the rumen - according Bassov. The experiment was carried out by the method of periods – a control and an experimental one. During both periods the buffalo calves were fed individually with portions consisting of 7 kg alfalfa hay and 2,1 kg concentrate mixture. During the experimental period to the concentrate mixture we added the polyenzyme preparation Xybeten-cel as a dose of 3 g per kg mixture. The results show with proof that the supplement of Xybeten-cel increase the quantity of the ammonia in the rumen before feeding - p 0.1 and 2,5 hours after feeding - p0.01; of the propion acid - C3 2,5 hours after feeding - p0.01 and 5 hours after feeding p0,001 and the valerian acid - C5 5 hours after feeding - p0.1. Regarding the quantity of vinegar acid - C2 the results show that it is reduced 2,5 hours after feeding - p0.01 and 5 hours after feeding - p0.001. Xybeten-cel at the dose of 3 g/kg concentrate mixture increases the number of Entodinium sp. infusoria 2,5 hours after feeding - p0.001 and Isotricha sp. infusoria 5 hours after feeding - p0.01.
