摘要

目标在断奶期和断奶后使用的肉牛犊牛管理策略可对生产链中的生长性能和健康产生广泛影响。由于肉牛-小牛饲养者在这些生产阶段可采用多种不同的方法,因此推广教育工作者必须了解哪些管理策略最常用,以及在哪些方面可能存在教育差距。本研究的目的是确定阿拉巴马州生产者对采用肉牛犊断奶和背景饲养策略的看法、农场应用情况和潜在障碍。材料和方法 2022 年 3 月,我们编制了一份在线调查问卷,共 24 个问题,并分发给阿拉巴马州的养牛生产者。问题涉及生产者是否使用管理性断奶和背景饲养策略,受访者根据这一回答按照预先确定的问题轨迹进行回答。结果与讨论共收到 214 份完整的回答,94% 的受访者认为他们的经营是奶牛-小牛经营。大多数参与者(46%)的牛群规模在 50 头奶牛或以下。快速断奶是生产者使用最广泛的断奶方法(55%)。半数以上(61%)的生产者表示会对犊牛进行背景调查,另有 25% 的生产者表示在某些年份会对犊牛进行背景调查,但并非总是如此。对于不对犊牛进行背景处理的受访者来说,市场的不可预测性是决定保留犊牛进行背景处理还是在断奶后立即出售的主要原因。采用管理性断奶和背景处理策略的生产商在经营中面临的主要挑战包括投入成本、土地供应和市场可预测性。受访者销售背景犊牛的方法各不相同,49% 的受访者利用当地牲畜拍卖会出售犊牛。推广教育者可应用这些数据创建以牛背景为中心的资源,帮助改进断奶后管理的潜在应用。

Assessment of weaning and backgrounding management practices used by Alabama beef cattle producers

Objective

Beef calf management strategies used during the weaning and postweaning period can have extended effects on growth performance and health in the production chain. With the number of different practices beef cow-calf operators can use during these stages of production, it is important for Extension educators to understand which management strategies are most commonly used and where educational gaps might exist. The objective of this study was to determine farmer perceptions, on-farm applications, and potential barriers to adopting beef calf weaning and backgrounding strategies among Alabama producers.

Materials and Methods

An online survey with 24 total questions was developed and distributed to cattle producers in the state of Alabama in March 2022. Questions addressed whether producers use managed weaning and backgrounding strategies, and respondents followed a predetermined question track based on this response.

Results and Discussion

A total of 214 complete responses were received with 94% of respondents considering their operation to be a cow-calf operation. Most participants (46%) had a herd size of 50 cows or less. Abrupt weaning was the most widely used method of weaning (55%) among producers. Over half (61%) of producers indicated they background their calves, and another 25% stated that they do in some years but not always. For respondents that do not background their calves, market unpredictability is the main driver surrounding the decision to keep calves for backgrounding or to sell immediately after weaning. Key challenges producers who practice managed weaning and backgrounding strategies face in their operations include input costs, land availability, and market predictability. Methods for marketing backgrounded calves differed across respondents, with 49% of respondents using local livestock auctions to sell calves.

Implications and Applications

Developing demonstration data models to address cost benefits of weaning and backgrounding may help producers evaluate areas of challenges identified in this survey. Extension educators can apply these data to create resources centered around backgrounding cattle to help improve potential applications of management after weaning.
