Effect of L - Lysine - Monohydrochloride supplementation on body weight, feed and energy utilization in broiler chicks

Abstract

The effect of feeding increasing levels of dietary lysine was 
studied in broiler chicks. Graded levels of L - lysine HCl: 0.0, 0.1, 0.2, 
0.3 and 0.4% were used as treatments. Results showed that increasing 
the dietary level of L - lysine HCI increased weight gain, feed intake 
and improve efficiency of feed utilization. Carcass protein, fat, gain in 
protein and fat paralleled the trend in weight gain. Chicks given the 
lysine adequate diet had the best feed conver- sion ratio and the 
highest weight gain, feed intake, carcass protein and fat contents, 
whereas those given the basal diet had the poorest feed conversion 
ratio and the lowest weight gain, rem intake, carcass protein and fat 
contents.
