Abstract

A combination of well trained handlers and properly designed facilities will reduce stress on cattle and improve both handling efficiency and productivity of cattle. Solid sides on both the single file chute and the squeeze chute will facilitate cattle movement and reduce lunging at the headgate. To reduce balking, distractions which impede cattle movement must be eliminated from handling facilities. Some of the most common distractions which make cattle balk in a chute are: a jiggling chain hanging in a chute, shiny reflections on metal, puddles, shadows, seeing a visible person and a high pitched noise. Cattle should be moved into the handling facility in small groups and the crowd pen should be filled only half to three-quarters full.

摘要

训练有素的操作人员与设计合理的设施相结合,将减轻牛的应激反应,并提高牛的处理效率和生产性能。单排通道和挤压通道的坚固侧板将便于牛移动,并减少其在闸门处的猛冲。为减少牛群犹豫不前,必须消除处理设施中阻碍牛移动的干扰因素。在通道中导致牛群犹豫不前的一些最常见干扰因素包括:通道中晃动的链条、金属上的反光、水坑、阴影、看到可见的人以及高音噪音。牛应以小群的方式赶入处理设施,拥挤圈的填充量应仅为半满至四分之三满。
