Cooked sun-dried blood meal a potential source of lysine II- Effect on broiler performance

Abstract

The effect of feeding increasing levels of dietary cooked sun-dried blood 
meal as a source of lysine was studied in broiler chicks. Graded levels of L
lysine 0.0, 0.1, 0.2, 0.3 and 0.4% derived from 0.0, 1.45, 2.9, 4.35 and 5.8% 
blood meal was used as treatments. Results showed that increasing the 
dietary level of derived lysine, significantly (p < 0.01) increased weight gain 
and improved efficiency of feed utilization. Dressing percentage on hot and 
cold carcass bases, carcass protein and fat paralleled the trend in weight 
gain. However, fat was significantly (p < 0.01) reduced in chicks fed the ad
eqate level of 0.4% derived lysine. Energy and nitrogen retained in the body 
significantly (p < 0.01) increased with blood meal addition.
