ABSTRACT
The present study was carried out to evaluate the effect of sire and environment on growth performance of grade-2 Brahman calves. A total of 70 grade-2 Brahman calves produced from 6 sires (14BR0043, 7BR-524, 14BR0040, 7BR-527, 14BR0041, 7BR-522) were included to study the effect on growth performance on 8 different areas (Barisal, Chattogram, Dhaka, Khulna, Mymensingh, Rajshahi, Rangpur, Sylhet). Analyses were performed by using Statistical Analysis System computer program (SAS). Sires had significant effect (p0.05) on birth weight, 3-month, 9-month and 12-month weights of progeny. The highest mean birth weight (32.27±0.59 kg) and 1-month weight (57.58±2.11 kg) of calves was found from the sire 14BR0040 and 14BR0041, respectively. The highest mean of 3-month (81.57±3.13 kg), 6-month (186.71±6.20 kg), 9-month (332.43±8.07 kg), 12-month (463.57±13.61 kg) and 24-month (903.33±16.71 kg) weights were found by sire 7BR-524, 14BR0043, 14BR0043, 7BR-524 and 14BR0040, respectively. The area significantly (p
