摘要

本研究以调查肉牛生产系统为目的进行。对孟加拉国每个司的两个县的肉牛生产进行了基线调查。该研究的目的是更新对牛肉增肥者在其自身环境中的状态的了解。基线调查的结果显示,拉杰沙希省的主要养牛人(90%)是用自己的钱开始养牛的,其次是达卡、库尔纳、巴里沙尔、查图格拉姆、锡尔赫特和朗布尔,这一比例分别为50%、40%、50%、40%、50%和55%。巴里沙尔省平均每个农场的牲畜存栏数为4.93头,显著高于达卡(4.35头)、库尔纳(4.71头)、拉杰沙希(3.83头)、查图拉姆(3.35头)、锡尔赫特(4.29头)和兰布尔(3.69头)。研究区库尔纳区、巴里沙尔区和朗布尔区每场土牛的平均规模分别为2.14头、2.63头和2.77头,显著低于达卡区、拉杰沙希区、查图格拉姆区和锡尔赫特区的平均规模(3.47头、3.27头、3.40头和3.93头)。育肥计划的平均持续时间达卡区(18.6个月)明显高于兰浦尔区(11.6个月)。大多数农民采用半集约化饲养方式。Rajshahi和Rangpur地区供肉牛的稻草量(3.57 kg /h/d)显著低于达卡、库尔纳、巴里沙尔、Chattogram和锡尔赫特地区(4.38 kg、4.57 kg、4.82 kg、4.32 kg和4.32 kg)。Barishal、Sylhet和Rangpur地区的肉牛精料供给量分别为817.86、814.71和887.50 g,显著高于Dhaka、Khulna、Rajshahi和Chattogram地区的肉牛精料供给量分别为758.82、721.43、772.22和739.71 g。综上所述,孟加拉国各区在人口统计信息、育肥资金来源、畜群规模、育肥持续时间、生产制度和饲养制度等方面存在差异。

Indigenous beef cattle production scenario in Bangladesh
The study was carried out with the interest of investigate the beef cattle production system. A baseline survey was conducted on beef cattle production in Bangladesh from two districts of each division. The study was conducted to up-date knowledge on the state of beef fatteners in their own environment. The findings of the baseline survey revealed that major beef fatteners (90%) in Rajshahi division started their cattle fattening using own money, followed by 50%, 40%, 50%, 40%, 50% and 55% in Dhaka, Khulna, Barishal, Chattogram, Sylhet and Rangpur, respectively. The average size (4.93) of livestock holding per farm in Barishal division was considerably higher than that of Dhaka (4.35), Khulna (4.71), Rajshahi (3.83), Chattogram (3.35), Sylhet (4.29) and Rangpur (3.69), respectively. In the study area, the average size (2.14, 2.63 and 2.77) of indigenous cattle per farm in the division of Khulna, Barishal and Rangpur, respectively was considerably lower than those (3.47, 3.27, 3.40 and 3.93) of Dhaka, Rajshahi, Chattogram and Sylhet division, respectively. The average duration (18.6 month) of the fattening program was considerably higher in Dhaka division than that (11.6 month) of Rangpur division. Majority of the farmers followed semi-intensive feeding system. The amount of rice straw/h/d supplied to the beef cattle is remarkably lower (3.57 and 3.72 kg) in Rajshahi and Rangpur division than those (4.38, 4.57, 4.82, 4.32 and 4.32) in the division of Dhaka, Khulna, Barishal, Chattogram and Sylhet, respectively. The amount of concentrates supplied (817.86, 814.71 and 887.50 g) to their beef cattle in Barishal, Sylhet and Rangpur, respectively was considerably higher than those (758.82, 721.43, 772.22 and 739.71 g) of Dhaka, Khulna, Rajshahi and Chattogram division, respectively. In conclusion, there were differences in demographic information, source of capitals for fattening, herd size, duration of fattening, production system and feeding system among the divisions of Bangladesh.
