An animal's action, or inaction, is the direct result of a stockman's action or inaction. The Stockman's Scorecard is a novel observation instrument that has been proven to be a valid and reliable tool to measure the quality of beef cattle stockmanship. Specific handler actions have been weighted based on their perceived negative relationship to cattle stress from handling. The purpose of this article is to 1) document the initial use of the scorecard in a beef cattle feedlot setting and 2) provide further support to its validity by establishing an association with other quantitative and qualitative means of evaluating stockmanship. The Scorecard was used at 39 beef feedlots in Texas between March 2018 and April 2019. Eighty-four stockman were observed, and the average score received was 84.5 (SD = 14.73, range = 20 to 100). The most frequent mistakes observed were as follows: fills crowd pen/tub over half full ( = 39), slow to remove pressure ( = 29), uses unnecessary noise ( = 25), stands in front and taps rear ( = 24), and fails to regulate animal flow through a pinch point ( = 22). A strong negative association (ρ = -0.51) was found between the points deducted from the Noise and Physical Contact theme of the Scorecard and the number of animals touched with an electric prod from the BQA Feedyard Assessment. Moderate negative associations were found between the Scorecard final score and the number of animals that vocalize in the chute prior to procedures (ρ = -0.31). Those stockmen that scored above average on the Scorecard were qualitatively observed to be calm and quiet while working with the cattle (Kappa = 0.44). The qualitative disposition of cattle had little effect on the final score of stockmen using the Scorecard (Kappa = 0.17). The use of the Scorecard in a feedlot setting has demonstrated that as stockman scores decrease, there is an increase in the number of negative actions toward cattle and a negative behavioral response of the cattle themselves. Establishment of an association between a stockman's score using the Stockman's Scorecard and the animal-based observations from the BQA Feedyard Assessment further strengthens the validity of the Stockman's Scorecard as a tool to measure the quality of beef cattle stockmanship. The Scorecard has application as a tool to identify specific stockmanship deficiencies in order to target stockmanship training.
动物的行为或不作为是饲养员行为或不作为的直接结果。饲养员计分卡是一种新颖的观察工具,已被证明是衡量肉牛饲养管理质量的有效且可靠的工具。根据特定饲养员行为与因处理导致的牛应激之间的感知负面关系对其进行了加权。本文的目的是:1)记录计分卡在肉牛饲养场环境中的首次使用情况;2)通过与评估饲养管理的其他定量和定性方法建立关联,为其有效性提供进一步支持。2018年3月至2019年4月期间,在得克萨斯州的39个肉牛饲养场使用了计分卡。观察了84名饲养员,获得的平均分数为84.5(标准差 = 14.73,范围 = 20至100)。观察到的最常见错误如下:将畜栏/料槽装至超过一半满( = 39)、解除压力缓慢( = 29)、使用不必要的噪音( = 25)、站在前面轻拍牛后部( = 24)以及未能调节动物通过狭窄通道的流量( = 22)。计分卡的噪音和身体接触主题所扣分数与BQA饲养场评估中用电棒触碰的动物数量之间存在强烈的负相关(ρ = -0.51)。计分卡最终得分与在操作前在斜槽中发声的动物数量之间存在中度负相关(ρ = -0.31)。定性观察发现,在计分卡上得分高于平均水平的饲养员在与牛打交道时冷静且安静(卡帕系数 = 0.44)。牛的定性性情对使用计分卡的饲养员最终得分影响很小(卡帕系数 = 0.17)。在饲养场环境中使用计分卡表明,随着饲养员得分降低,对牛的负面行为数量增加,牛自身的负面行为反应也增加。饲养员使用饲养员计分卡的得分与BQA饲养场评估中基于动物的观察结果之间建立关联,进一步加强了饲养员计分卡作为衡量肉牛饲养管理质量工具的有效性。计分卡可作为一种工具,用于识别特定的饲养管理缺陷,以便针对饲养管理培训。
