Abstract

ABSTRACT This study aimed to investigate the effects of animal type, on-farm handling, and transport conditions on temperament of beef cattle pre-slaughter. The study evaluated 4,061 cattle batches, averaging 49 animals, with a total of 199,026 cattle. Temperament was evaluated through a behavioral assessment carried out based on the temperament shown by cattle when approached by humans. One of three different temperament scores were assigned to each batch: calm, anxious, or excitable. Excitable temperament was reported in animals subjected to long transport time and distance and high loading density. The degree of carcass fatness was higher in calm animals, followed by anxious animals, with the excited temperament animals having the lowest carcass fatness degree. Older animals showed more excitable temperament, while younger animals showed calmer temperament. The excitable temperament was more evident in horned animals in relation to polled animals. Animal temperament was more reactive in batches with older cattle, low carcass fatness degree, and with more than 20% horned animals. Good handling and loading facilities and procedures at the farm contributed to adequate cattle temperament expression prior to slaughter.

动物种类、处理和运输条件对肉牛屠宰前性情的影响

摘要本研究旨在探讨动物类型、农场处理和运输条件对肉牛屠宰前性情的影响。该研究评估了4061批牛，平均49只，共199026头牛。气质是通过一项行为评估来评估的，该评估基于牛在被人类接近时表现出的气质。三种不同的气质得分中的一种被分配给每一批：冷静、焦虑或易激动。据报道，在长运输时间和距离以及高装载密度的动物中存在兴奋性。平静动物的胴体肥胖程度较高，其次是焦虑动物，其中兴奋性动物的胴体脂肪程度最低。年龄较大的动物表现出更易激动的气质，而年龄较小的动物则表现出更冷静的气质。与有角动物相比，有角动物的易兴奋性更为明显。在年龄较大、胴体脂肪度较低和有角动物超过20%的情况下，动物性情在批次中更具反应性。农场良好的装卸设施和程序有助于在屠宰前充分表现牛的性情。
