Abstract weight. The treatments were (1) NRC allowances (2) NRC allowances +10 g YC Yea-Sacc 1026 /head per day (3) local allowances (4) local allowances +10 g YC /head per day. The daily ration cover the animal allowances, and consisted of concentrate feed mixture (CFM), dried sugar beet pulp, tapioca, sunflower meal waste: berseem or darawa, rice straw (C:R ratio a bout 65:35 dry matter basis). The treatments extended to 180 days after parturition. The addition of YC to animal diets of the local allowances group results higher (P>0.05) values of nutrients digestibility for OM, OM, CP, CF and EE, but higher digestibility (P<0.05) due to the supplementation by YC on NFE. Supplementation of YC to animaL diets enhance (P<0.05) feed conversion for dry matter (DM) and gross starch value (GSV). Supplementation of YC to animal diets showed significant (P<0.05) higher milk and FCM4% yield. The animal were fed local allowances and supplemented with YC showed higher (P>0.05) milk yield and 4% FCM yields than those recorded with NRC allowances. The treatments had no significant (P>0.05) effect on colostrum composition. Experimental animal, which fed local allowances, showed significantly higher (P<0.05) milk fat % than those fed NRC allowances, and also supplementation . by YC to buffalo diets showed . no . significant differences. Supplementation by YC showed a decrease (P>0.05) of milk protein, lactose and SNF % compared to the non-supplemented groups. Also animal which fed local allowances decreased (P<O.OS) lactose and SNF, but not influenced protein%. Fat, protein, lactose, TS, SNF and Ash yields were significantly (P<O.OS) higher for groups fed diets supplemented with YC than those non-supplemented. No significant (P>O.OS) differences observed in fat, protein, lactose, TS, SNF and ash yields due to applying iocal allowances. Supplementation by YC showed no significant (P>0.05) effect on serum TP, Alb., Glo., urea, creatinine concentrations and A: G ratio, but there. was significant (P<0.05) decrease in serum total lipids. The local allowances showed significant {P<0.05) increase of serum TP, Alb, A: G ratio and total lipids, while Glo, urea and creatinine not influenced. |
