Abstract: A total of 45 Ile-de-France lambs were divided into three groups with similar cha¬rac¬teristics. The lambs from experimental group I were individually supplemented with 8 g Immunobeta prebiotic and lambs from experimental group II  with the same amount of prebiotic + 4 g probiotic Zoovit.
When a live weight of 23-25 kg was attained, five male lambs from each group were slaughtered, and samples from musculus Longissimus Lumborum (m. LL) were collected.
The purpose of the study is to determine the effect of the added prebiotic and the prebiotic+probiotic combination on fatty acids, amino acids, cholesterol and organic acids. To fulfill the objective, the fatty acid and amino acid profiles of the meat, the content of cholesterol, organic acids, ribose and inosine were analyzed.
A statistically insignificant increase in all amino acids was demonstrated in lamb meat from experimental groups I and II as compared to controls. The amino acid content of m. LL of lambs whose ration was supplemented with Immunobeta prepbiotic was lower than that of animals that received the Zoovit + with Immunobeta combination.
The content of analysed fatty acids in lambs supplemented with the Immunobeta prepbiotic were inconsistently lower than respective values in control lambs. A similar tendency was found out for meat cholesterol.
The dietary supplementation with prebiotic and prebiotic + probiotic had not statistically significant effect on the content of organic acids, ribose and inosine in m. LL.
