Effect of In-activated and Dried Yeast on Productive Performance of Barki Lambs

Wafaa M.A. Ghoneem and A.E.M. Mahmoud

Abstract:
The present study aims to evaluate the effets of in-activated and dried yeast on Barki lambs. For that purpose thirty growing Barki male lambs (averaged 27 kg body weight, 9 months old) were divided into 3 groups (10 in each) according to live body weight for 90 days trial to study the effects of yeast supplementation on digestibility, growth performance, blood and rumen liquor parameters. The treatments contained 0 yeast (T1), 5 g h-1 day-1 either of inactivated yeast (T2) or dried yeast (T3). Results showed that the digestibilities of most nutrients and fiber fraction, nutritive value as TDN, total and average daily gain and feed conversion efficiency were improved by supplementation of inactivated yeast, followed by dried yeast compared to control. However, no differences (p<0.05) were observed in rumen pH and ammonia N. There were any adverse effects on blood parameters due to yeast supplementation. Based on this experiment, yeast supplementation (5 g h-1 day-1) especially with inactivated yeast could be recommended to improve growth performance of growing lambs.
