AB  - A study was conducted to evaluate the utilization of Dried Yeast (DY) as a source of lysine in broiler feeds. Three feeds, control (0.0% lysine and 0.0% DY), 0.25% Lysine and ).25% DY were compounded and tested on 270.0 Ross broiler chicks for 56 days. Data were collected on the proximate, calcium, phosphorus, amino acid composition of the feeds, performance and feed utilization of the broilers. It was observed that substitution of DY for lysine at 0.25% had no significant (p>0.05) effect on the proximate, calcium and phosphorus levels of the feeds. The proportion of the amino acids ( valine, arginine, leucine, isoleucine and glutamic acids) increased in DY feeds compared to the control. Mean final body weight (1.03±0.12 kg) and body weight gain (0.96±0,11 kg) of DY-fed broilers were significantly (p<0.05) higher than (0.90±0.04 kg) and (0.83±0.04 kg) of the control but similar to those of lysine-fed broilers (0.98±0.04 kg) and (0.91±0.04 kg), respectively. The results suggest that dried yeast can be used as a lysine source in broiler feeds.
