Abstract

Sheep breeding is of great importance for the Tuva Republic. The sheep population exceeds 1.2 million heads. Surveys were carried out to find out the additional reserves for increasing lamb meat production. The typological structure was defined with the method based on the motor response to feeding, which was developed by D.K. Belyaev and V.N. Martynova (1973) and improved by V.S. Zarytovsky and M.I. Liev (1990). It provides the allocation of three behavioral types described as strong early maturing even-tempered, strong early maturing short-tempered, and weak late-maturing for the first, second, and third behavioral types, respectively. The ram lambs of group one were at definite advantages over the animals of groups two and three. Thus, increases in the carcass fresh weight, the slaughter weight, and the carcass yield comprised 0.92 and 1.85 kg (3.32 and 6.82%), 0.97 and 1.90 kg (3.58 and 7.00%), and 1.80 and 2.06%, respectively. The percentages of carcass meat and bone tissues varied within 69.61–69.96 and 16.46–17.36%, respectively. The rise in lamb population and the use of ram lambs of the first feeding behavioral type (strong early maturing even-tempered) contributed to increasing the potential of lamb meat production. The findings based on the complex survey results prove the dependency of traits of economic importance on the type of animal feeding behavior. Therefore, the survey findings supported by scientific knowledge can contribute to improving the indigenous short fat-tailed sheep of Tuva breed and to developing recommendations based on the feeding-behavioral type information.

饲养行为对图瓦公羊的生物学和生产特性的影响

摘要

绵羊育种对图瓦共和国非常重要。绵羊数量超过120万头。进行了调查以找出增加羊肉产量的额外储备。类型结构由基于对进食的运动反应的方法定义,该方法由 DK Belyaev 和 VN Martynova (1973) 开发,并由 VS Zarytovsky 和 ​​MI Liev (1990) 改进。它分别为第一、第二和第三行为类型提供了三种行为类型的分配,这些行为类型被描述为强早熟脾气暴躁、强早熟脾气暴躁和弱晚熟。第一组的公羊羔羊明显优于第二组和第三组的动物。因此,胴体鲜重、屠宰重量和胴体产量的增加分别为 0.92 和 1。分别为 85 公斤(3.32 和 6.82%)、0.97 和 1.90 公斤(3.58 和 7.00%)以及 1.80 和 2.06%。胴体肉和骨组织的百分比分别在 69.61-69.96 和 16.46-17.36% 之间变化。羔羊数量的增加和第一种饲养行为类型(强早熟均匀回火)的公羊羔羊的使用有助于增加羊肉生产的潜力。基于复杂调查结果的发现证明了经济重要性特征对动物饲养行为类型的依赖性。因此,由科学知识支持的调查结果有助于改进图瓦品种的本地短肥尾羊,并根据饲养行为类型信息制定建议。胴体肉和骨组织的百分比分别在 69.61-69.96 和 16.46-17.36% 之间变化。羔羊数量的增加和第一种饲养行为类型(强早熟均匀回火)的公羊羔羊的使用有助于增加羊肉生产的潜力。基于复杂调查结果的发现证明了经济重要性特征对动物饲养行为类型的依赖性。因此,由科学知识支持的调查结果有助于改进图瓦品种的本地短肥尾羊,并根据饲养行为类型信息制定建议。胴体肉和骨组织的百分比分别在 69.61-69.96 和 16.46-17.36% 之间变化。羔羊数量的增加和第一种饲养行为类型(强早熟均匀回火)的公羊羔羊的使用有助于增加羊肉生产的潜力。基于复杂调查结果的发现证明了经济重要性特征对动物饲养行为类型的依赖性。因此,由科学知识支持的调查结果有助于改进图瓦品种的本地短肥尾羊,并根据饲养行为类型信息制定建议。羔羊数量的增加和第一种饲养行为类型(强早熟均匀回火)的公羊羔羊的使用有助于增加羊肉生产的潜力。基于复杂调查结果的发现证明了经济重要性特征对动物饲养行为类型的依赖性。因此,由科学知识支持的调查结果有助于改进图瓦品种的本地短肥尾羊,并根据饲养行为类型信息制定建议。羔羊数量的增加和第一种饲养行为类型(强早熟均匀回火)的公羊羔羊的使用有助于增加羊肉生产的潜力。基于复杂调查结果的发现证明了经济重要性特征对动物饲养行为类型的依赖性。因此,由科学知识支持的调查结果有助于改进图瓦品种的本地短肥尾羊,并根据饲养行为类型信息制定建议。
