摘要

加拿大的小牛生产者正面临着采用有助于提高经济和环境可持续性以及公众对牛肉生产看法的管理方法和技术的压力。我们的目标是描述加拿大牛群的技术采用、管理和记录方法,评估牛群属性、生产结果和采用之间的关联,并确定改进的机会。我们分析了通过国家监测计划招募的 131 位加拿大母牛生产者的调查。据报告,母牛个体记录(80%)和饲料检测(84%)是目前或偶尔使用的常用方法,其次是农场磅秤(66%)。西部牛群可能使用饲料检测和营养学家、离子探测器和促生长植入物,而东部牛群通常使用繁殖技术。大型牛群(大于 300 头奶牛)更有可能采用有助于数据采集的技术(如称重秤)和遵循推荐的实践(如饲料检测)。纸张是主要的记录保存格式。生产记录通常用于淘汰和替代母牛的选择。与以前的调查相比,全国各地的技术使用率都有所提高,生产者正在实施有助于提高生产效率的措施。然而,仍有机会增加对支持个体动物和牛群数据的技术的使用,以帮助牧场做出明智决策。

Technology adoption and management practices used in Canadian cow-calf herds
Canadian cow-calf producers are facing pressure to adopt management practices and technologies that help increase the economic and environmental sustainability, and public perception of beef production. Our aim was to describe technology adoption, management and record keeping practices in Canadian cow-calf herds, assess associations between herd attributes, productivity outcomes and adoption; and identify opportunities for improvement. Surveys from 131 Canadian cow-calf producers recruited through a national surveillance program were analyzed. Individual female records (80%) and feed testing (84%) were commonly reported as currently or occasionally used, followed by on-farm weigh scales (66%). Western herds were likely to utilize feed testing and nutritionists, ionophores and growth promoting implants, while eastern herds commonly used reproductive technologies. Large herds (>300 cows) were more likely to adopt technologies that aid in data capture (i.e., weigh scales) and follow recommended practices (i.e., feed testing). Paper was the main record keeping format. Production records were commonly utilized for culling and replacement heifer selection. Technology use has increased across the country compared to previous surveys and producers are implementing practices to help increase production efficiency. However, there is an opportunity to increase use of technologies that support individual animal and herd data to help inform ranch decisions.

期刊介绍: Published since 1957, this quarterly journal contains new research on all aspects of animal agriculture and animal products, including breeding and genetics; cellular and molecular biology; growth and development; meat science; modelling animal systems; physiology and endocrinology; ruminant nutrition; non-ruminant nutrition; and welfare, behaviour, and management. It also publishes reviews, letters to the editor, abstracts of technical papers presented at the annual meeting of the Canadian Society of Animal Science, and occasionally conference proceedings.
