Abstract

A study was conducted to analyze the dairy farming sector of Bangladesh from an economic viewpoint. Primary data was collected from smallholder dairy farms using survey questionnaires. A Cobb-Douglas production function and multiple regression models were estimated to analyze farm milk productivity and gross margin of the dairy farms. Surveyed dairy farms owned on an average 3.07 milking cows comprising 0.37 indigenous and 2.70 crossbred cows. Average milk productivity was 7.80 liter per cow per day, in which indigenous cow milk productivity was 1.9 1iter per day and crossbred cow milk productivity was 6.48 liter per cow per day. The study found that average daily milk production of small, medium, and large dairy farms were 5.45, 32.50, and 59.83 liter, respectively. Average monthly revenue and cost of milk production were US$ 79 and US$ 21 per cow, resulting in the average net return of US$ 58 per cow per month. Both quantitative estimation and t test results indicated a positive and statistically significant relationship between farm size and milk productivity and gross margin. The study findings also indicate that crossbred cows are providing higher economic benefits to the dairy farmers compared to the indigenous breeds. Despite being smallholder and subsistence, dairy farming shows potential for increasing returns to scale, and hence, there is a scope for further growth of the sector.

摘要

一项研究从经济角度对孟加拉国的奶牛养殖部门进行了分析。通过调查问卷从小农户奶牛场收集了原始数据。估计了柯布 - 道格拉斯生产函数和多元回归模型,以分析奶牛场的牛奶生产率和毛利率。被调查的奶牛场平均拥有3.07头泌乳奶牛,其中包括0.37头本地奶牛和2.70头杂交奶牛。平均牛奶生产率为每头奶牛每天7.80升,其中本地奶牛的牛奶生产率为每天1.9升,杂交奶牛的牛奶生产率为每头奶牛每天6.48升。研究发现,小型、中型和大型奶牛场的平均日产奶量分别为5.45升、32.50升和59.83升。每头奶牛每月的平均牛奶收入和生产成本分别为79美元和21美元,每头奶牛每月的平均净回报为58美元。定量估计和t检验结果均表明农场规模与牛奶生产率和毛利率之间存在正相关且具有统计学意义。研究结果还表明,与本地品种相比,杂交奶牛为奶农带来了更高的经济效益。尽管是小农户且以自给自足为主,但奶牛养殖显示出规模报酬递增的潜力,因此,该部门有进一步增长的空间。
