Effects of feeding diets containing different levels of silkworm pupae meal on the performance of broiler chickens

In this experiment effects of diets containing different levels (0,3,6 and 9%) of silkworm pupae meal (SWPM) on the performance of male broiler chicks using 13 feeding treatments in a completely randomized design were evaluated. Seven hundred and eighty day-old male broiler chicks (Arain) were randomly divided into 52 groups of 15 chicks each. Four replicates were assigned to each treatment, randomly. The experiment lasted for 49 days. The results showed that different levels of SWPM had no significant effects on daily feed intake and weight gain during 0-42 d period. In total experimental period (0-49 d of age) daily feed intake and weight gain considerably were higher in groups fed diets containing silkworm pupae meal compared with chicks fed diets containing fish meal as a main source of animal protein. None of the feeding methods caused significant effect on feed conversion ratio in 0-42 and 0-49 days of age. However, total chicks fed diets containing different levels of SWPM during rearing period had a higher body weight mean than control group at 49 days of age (2136 g vs. 2046 g). Moreover, the treatments had no significant effects on relative percentage of carcass, abdominal fat and pancreas to live body weight at 49d of age. According to the results of this experiment we can include SWPM in broiler chick diets as a main source of animal protein, without having any adverse effects on their performance.
