Abstract
Twenty-four culled female buffaloes {12 heifers (H) and 12 adult (A)} were used to evaluate the effects of two types of commercial yeast culture {More yeast (1) and CenMose (2)1 trade name) on nutrient digestibility, nutritive value. average daily gain. feed conversion and blood constituents compared to control (C) groups with no supplement. Each group of animals were divided into three similar subgroups (4 each) on the basis of initial age and initial body weight as follows:

Yeast cultures were top-dressed on the moming concenlrate diet at one level of 10 9 I head I day. Subgroups Hl and A 1 were given More yeast while subgroups H2 and A2 were given CenMose. The subgroups of HC and AC were used as control. All animals were fed for 90 days on a traditional diet comprising of concentrate mixture and wheat straw. Neither nutrients digestibiiity nor nutritive values were affected by yeast cultures in both heiters and buffalo cows. Yeast cultures increased the average daily gain (ADG) and decreased daily feed intake resulted in an improvement of feed efficiency in heifers. While, CenMose improved the ADG with a slight increase in daily feed intake and gave higher feed efficiency compared to Moreyeast and control one . .A:2. and H2 showed Ihe best ones in feed conversion (5.33 and 5.09 TDN I Gain. resp.) and the ADG were (1.294 and 1.139 Kg, resp.). More yeast did not affect in the performance of buffaloes while sensible improvement was shown in heifers. Blood analysis showed no significanl differences among all groups in total protein, total cholesterol and total lipids.
Addition of yeast culture including its growth medium in concentrate diet of culled female buffaloes improve the average daily gain and feed conversion during a gO-day finishing period.
