牛仔分类牛群的工作

进行分类作业时,牧场主人检阅牛群的仔细程度也许会超出您的预期范围。辨识出走失的牛只后,牧场会通知牛只的主人来将它们带回。小心辨识牛妈妈的过程被称为“牛妈妈辨识” (mother up) ;区分小牛是为了烙印幼牛及将年龄稍长的小牛带离妈妈的身边。

牧场主人也需决定哪些牛只要贩售。现为“空袋” (即未处于哺乳期的乳房) 的干牛,其状况好过于那些有小牛要照料的母牛。怀孕的干牛不可出售。尚未怀孕的“待孕” (open) 牛,则视它们的情况决定是否要保留或出售。


In the sorting process, ranchers go through their herds more carefully than you might imagine. Stray cows are identified and their owners are called to retrieve them. Mother cows are carefully identified in a process called "mother up." Calves are separated so that young calves can be branded and older calves weaned from their mother.

Ranchers also decide which cows they want to sell. An empty "bag," or udder, can identify a dry cow, which tends to be in better condition than a cow with calves. Pregnant dry cows are not sold. Animals that are not pregnant, called "open" cows, are kept or sold depending on their condition.
