EFFECTS OF SOME PROBIOTICS ON THE GROWTH INDICES IN YOUNG SHEEP

Researches were carried out in order to follow the effect of ruminal microsimbionts activity stimulation, after supplementation with Lactobacillus plantarium, Streptococcus fecium, Pediococcus acidolactici (0.13 g/kg concentrate mixture) and Sacharomyces cerevisiae Yea-Sacc1026, (3.2 g/kg concentrate mixture), on nutritive and productive indices in lambs. During the experimental period (23 – 58 days), lambs were fed, ad libitum, with a diet containing alfalfa hay and a complex mixture insuring 16 % crude protein (PBD). Differences observed between the two groups (L1 – control, n = 11; L2 – experimental, n = 11), concerning the growing performances, were significant (p
