Influence of the addition of the prebiotic Immunobeta and its combination with the probiotic Zoovit on the development of the digestive system and the microbiological analysis of rumen and intestinal contents in Ile de France lambs

The aim of the study was to determine the effect of taking the prebiotic Immunobeta and a combination of the prebiotic Immunobeta + probiotic Zoovit, on the development of the digestive tract and the microbial composition in lambs from Ile de France. The object of the study were 45 lambs of the Ile de France breed, divided into three groups. The first experimental group of lambs received 8 g of the prebiotic Immunobeta, and those from the second experimental group the same amount of prebiotic + 4 g of the probiotic Zoovit. At the end of the experiment, 5 male lambs from each group were slaughtered. The volume of the rumen, the length of the papillae and the intestines were determined, and microbiological studies were performed. An increase in the small intestine was found in the lambs from I and II experimental groups, in the large intestine in animals from II and the control, as well as a greater capacity of the rumen in the lambs from II experimental group compared to the control (P˃0.05). The length of the rumen papillae in lambs from experimental groups I and II was greater than in the control (P˃0.05). In the lactic acid bacteria in the rumen, we found a decrease in the group receiving the synbiotic compared to the first experimental and control groups, and in the small and large intestines it was the lowest in the group receiving Immunobeta compared to the other two groups.
