Effects of additional 1% protein concentrate with commercial broiler feed on comparative growth performance of Lohman meat and Ross 308 strain of broiler.

Abstract

A total of 40 day old chicks were collected of which half numbers were Lohman meat stain (A) and other half numbers were Ross 308 strain (B) of broiler. Each strain of chicks were grouped into the two groups that is total four groups of chicks. Both A and B group had one replicate group of each group (group C and group D). The replicate groups were deprived off providing 1% additional protein concentrate with their feeds and the A and B group provided with 1% additional protein with their supplied commercial feeds. Birds were reared for 30 days and routine vaccination and treatment were carried out. The findings indicated that the growth performance of two strain (Lohman meat and Ross 308) were same. Moreover, no significant differences was observed of feed intake, body weight gain and feed conversion ratio for two broiler strain. In this study, the recorded tabulated data showed only numerical differences. So, it is clear that the two broiler strains are the same strains in terms of growth performance, FCR and survivability.
