摘要

利用2013年的一项调查数据,提供了14个农场经营和管理实践的采用率,以及美国草饲牛肉生产商采用的品种类型的频率。管理实践可分为3大类:一般管理(夏季遮阳、阉割、动物识别系统、疫苗接种、驱虫和昆虫控制)、生殖管理(规定繁殖季节、繁殖记录、妊娠检查、公牛试验和人工智能)、技术或信息管理(在互联网上搜索草饲牛肉信息、保存个体动物记录和检测饲料质量)。多变量probit和联合泊松模型用于分析采用管理实践的决定因素。提供了生产者使用品种的摘要。结果表明,参与牛-小牛部分并将草饲牛肉作为肉类销售的大型生产者更有可能采用大多数管理实践。安格斯品种和安格斯杂交品种是使用最多的动物。研究结果为研究和推广人员提供了见解,以确定草饲肉牛养殖场的主要结构和使用的实践,从而制定研究和教育计划,以进一步帮助草饲肉牛部分。

Adoption of management practices and breed types by US grass-fed beef producers
ABSTRACT Using data from a 2013 survey, adoption rates of 14 farm operations and management practices, as well as frequencies of breed types adopted by US grass-fed beef producers, are provided. The management practices are classified into 3 broad groups or categories: general management (access to shade during summer, castration, animal identification system, vaccination, deworming, and insect control), reproductive (defined breeding season, breeding records, pregnancy checking, bull test, and AI), and technological or informational (searching the internet for grass-fed beef information, keeping individual animal records, and testing the quality of forage). Multivariate probit and joint Poisson models were used to analyze determinants of adoption of the management practices. A summary of breeds used by producers is provided. Results indicate that larger-scale producers who were involved in the cow-calf segment and sold grass-fed beef as meat were the more likely adopters of most of the management practices. The Angus breed and Angus crosses were the most heavily used animals. The results provide insight for research and extension personnel in determining the predominant structure of grass-fed beef farms and the practices used and, hence, in developing research and educational programs to further assist the grass-fed beef segment.
