Abstract

The aim was to investigate the growth of certain non-carcass components and hind limb tissues using allometric coefficients in Saanen goat kids reared under natural and artificial systems and slaughtered at 80 days or 120 days of age. 42 Saanen kids were used in the study [(24 artificial reared kids (SA-80: 12 kids, SA-120: 12 kids), 18 natural reared kids (SA-80: 9 kids, SA-120: 9 kids)] for determination of indicated parameters. The effect of rearing system was not significant in weights of non-carcass components and hind limb tissue compositions, which indicates that, even though they were fed with milk replacers, artificial reared kids can have similar growth performance when they slaughtered at similar age with natural raised kids. However, slaughter age had significant effect on many non-carcass components, since the weight of the organs increases in parallel with animal’s live weight. It is seen that allometric growth of non-carcass parameters, except skin and testis in both rearing groups and stomach and intestines in natural rearing, was slower (b

天然和人工饲养条件下沙嫩山羊非胴体成分和后肢组织组成的异速生长

目的是利用异速生长系数研究80日龄和120日龄在自然和人工饲养体系下屠宰的萨宁山羊幼山羊某些非胴体成分和后肢组织的生长情况。42名Saanen儿童被纳入研究[24名人工饲养儿童(SA-80: 12名，SA-120: 12名)，18名自然饲养儿童(SA-80: 9名，SA-120: 9名)]，以确定指示参数。饲养方式对非胴体成分重量和后肢组织组成的影响不显著，说明即使饲喂代乳剂，人工饲养的仔鸡在相近年龄屠宰时的生长性能与自然饲养的仔鸡相近。然而，屠宰年龄对许多非胴体成分有显著影响，因为器官的重量与动物的活重平行增加。可以看出，除皮肤和睾丸外，其他非胴体参数的异速生长在两个饲养组和自然饲养组均较慢(b)
