Evaluation of growth performance of Brahman cross calves to local environment of Bangladesh

The present study was conducted using growth performance data on 624 Brahman cross (25%) calves collected from three villages adjacent to Bangladesh Agricultural University, Mymensingh, Bangladesh. Growth performance data of 289 Brahman cross (50%) calves were also collected from record sheet maintained at 12 Upazila Livestock Offices under the "Beef breed development project" of Department of Livestock Services to compare performance between 25% and 50% Brahman cross calves. Growth performance traits were considered birth weight, weight at three-, six-, nine-, twelve-month of age, average daily gain from birth to twelve-month of age. Calving difficulties (dystocia) and calf mortality were also included in the study area. The birth weight, weight at three-, six-, nine- and twelve-month average daily gain for 25% Brahman cross calves were 19.79±0.20, 52.72±1.31, 86.61±2.02, 129.90±3.08, 172.60±3.48 kg and 426.00±4.99g, respectively. The average birth weight (21.40±0.24 kg) and twelve-month weight (229.62±2.08 kg) of 50% Brahman cross calves were significantly higher (p
