An attempt was made to study the effect of supplementation of Lactobacillus acidophillus and
Saccharomyces cerevisiac individually and combination of both to feed, on growth performance
and feed conversion efficiency in goats. Sixteen of similar age and body weight were randomly
allotted to four treatments viz, T0 : concentrate (without probiotics), T1 : 2gm Lactobacillus acidophillus
per kg feed, T2: 2gm Saccharomyces Cerevisiac per kg feed, and T3 : mixture of 1g Lactobacillus
acidophillus + 1g Saccharomyces cerevisiac per kg feed was fed to the Osmanabadi goats. Observations
on the body weight gain showed the significant (P<0.05) differences among the treatments means.
The kids fed under treatment T3 showed higher average daily weight gain (88 gm) over the other
treatments, whereas the lowest average daily weight gain was recorded under treatment T0 i.e.
control group (26 gm). The mixture of probiotics (T3) was found most effective in reducing the feed
requirement, which was only 2.96 kg of weight gain. It is concluded that the use of probiotics either
single or in combination was useful for higher weight gain in goats
