Abstract
A study was conducted in ruminant research station, department of animal resources research, office of agriculture research, Ministry of agriculture. Twelve Awassi lambs and twelve Cyprus kids at age of 5-6 months and at average preliminary weight of 27 kg for sheep and 18 kg for kids were used in this study. Animal were divided randomly in to six treatment equal in number (4 in each treatment) fed in dividedly as follow: group (1) without (Saccharomyces Cerevisiae) (SC) and considered a control ration 0 SC, group (2) ration supplemented with 4g SC/animal/day and group (3) ration supplement with 8g SC/animal/day for both lambs and kids by using factorial experiment 2×3 to study the effect of supplementing baker's yeast (SC) to Awassi lambs and Cyprus kids ration on productive performance and digestibility. Ration were given an 4% from live body weight. The study was lasted for 9 weeks. Result showed absence of significant difference between the 3 levels of supplementation of SC in daily and total feed intake, average daily and total gain and fed conversion efficiency. Lambs (p<0.01) than kids, however, the interaction between type of animal and supplementing with SC recorded significant effect (P<0.01) among different groups in which control group of lambs was higher value where as control group for kids group the lower value. The group supplemented 8 gm SC gave significant (P<0.05) improvement in neutral and acid detergent fiber and crude protein digestibility while there ware no significant differences was observed for other digestible coefficient. Also, lambs significantly (P<0.05) higher than kids in crude protein and ether extract digestibility. Interaction between type of animal and supplementing with SC also recorded significant (P<0.05) effects among different groups except for dry matter and for ether extract digestibility.
