Abstract
An experiment was conducted to study the effect of four levels of blood meal on
the growth and carcass yield of broilers. For this purpose, 250 day-old chicks
were divided in five groups i.e., A, B, C, D and E. 0, 3, 4, 5 and 6 percent
levels of blood meal were mixed in the ration of the five groups respectively.
The chicks were reared on the experimental rations for six weeks and data on
feed consumption, weight gain, feed conversion ratio and dressing percentage
were recorded. Results revealed highly significant differences (P<O.O I) among
weight gain of broilers. Average weight gain of birds of groups A, B, C, D and E
was 1634.66, 1866.55, 1808.04, 1792.07 and 1755.34 9 respectively. The group B
(3% blood meal) gave best performance in terms of weight gain and carcass yield
as compared to all the other groups. Average feed consumption of broilers of
five groups was 4033.19, 3960.45, 4127.25, 4147.19 and 4149.19 g. Group B
consumed less feed. The average feed conversion ratio was 2.47, 2.12, 2.28, 2.31
and 2.36. Better feed conversion ratio was observed in birds of group B. The
average dressing percentage of broiler chicks of five groups was 56.23, 63.41,
61.4J, 60.38 and 57.74 percent. The broiler of group B showed better dressing
percentage (63.41). Non-significant differences were observed in weight of
edible parts like liver, gizzard and heart. It was concluded that the broilers
could be reared economically by using 3% of blood level as an animal protein
source in the broiler ration to save economy of producers.
