Abstract

Dairy production in Argentina has been intensified, but dairy farms are facing problems to increase productivity. This work aimed to identify the major constraints on milk production in dairy farms of the North East region of Buenos Aires province, Argentina. A survey was conducted to collect production data from 29 dairy farms. The major constraints were: insufficient water provision (there is one water trough every 19 ha), and insufficient natural and artificial shade for cows (1.8 and 2.9 m2 cow-1, respectively); old dairy facilities (dating back 21 years) and lack of investment in milking equipment; long milking times (3.3 hours per milking); deficiencies in soil phosphorus (9.3 mg kg-1) and sulphates (11.7 mg kg-1); presence of nitrates in cattle drinking water and inadequate effluent storage and distribution. According to the correlation analysis performed, it can be inferred that dairy farms that increased land productivity by increasing herd size did not improve farm infraestructure to meet new requirements. Investment to cope with the problems detected might increase milk production and improve the sustainability and profitability of dairy farms.

阿根廷布宜诺斯艾利斯省东北部奶牛场的技术生产特征

阿根廷的乳制品生产已经加强，但奶牛场在提高生产力方面面临问题。这项工作旨在确定阿根廷布宜诺斯艾利斯省东北地区奶牛场牛奶生产的主要制约因素。对29个奶牛场的生产数据进行了调查。主要制约因素是：供水不足（每19公顷有一个水槽），奶牛的天然和人工遮荫不足（分别为1.8和2.9平方米的cow-1）；乳制品设施陈旧（可追溯到21年前），对挤奶设备缺乏投资；挤奶时间长（每次挤奶3.3小时）；土壤磷缺乏（9.3 mg kg-1）和硫酸盐缺乏（11.7 mg kg-1）；牛饮用水中硝酸盐的存在以及废水储存和分配不足。根据进行的相关性分析，可以推断，通过增加牛群规模来提高土地生产力的奶牛场并没有改善农场基础设施以满足新的要求。投资解决发现的问题可能会增加牛奶产量，提高奶牛场的可持续性和盈利能力。
