摘要

本研究的目的是评估饲料限制和性别对鸡、兔和营养素肉质的物理、化学和组织化学参数的影响。鸡在14至21日龄时以70%的自由采食量限制，兔在42至49日龄时按70%的自由产食量限制，营养素在12至15周龄时按70的自由产气量限制。在限制之前和之后随意喂养动物。结果表明，与家兔和营养素相比，饲料限制、性别及其相互作用对肉鸡肉质的影响更大。饲料限制、性别及其相互作用的影响主要体现在肉的营养价值上，而对肉的物理测量的影响可忽略不计。饲料限制和性别之间的相互作用只影响兔子和海狸鼠的肌纤维横截面积。数据表明了肉的补偿生长、肌肉纤维分布和营养价值之间的关系。

A comparative study on the effect of quantitative feed restriction in males and females of broiler chickens, rabbits and nutrias. II. Meat quality

The objective of the study was to evaluate the effects of feed restriction and sex on the physical, chemical and histochemical parameters of meat quality in chickens, rabbits and nutrias. Feed restriction was applied at a rate of 70% ad libitum from 14 to 21 days of age in chickens, 70% ad libitum from 42 to 49 days of age in rabbits, and 70% ad libitum from 12 to 15 weeks of age in nutrias. Animals were fed ad libitum prior to and following restriction. The results showed stronger effects of feed restriction, sex, and their interaction on the meat quality of broiler chickens than in rabbits and nutrias. The effect of feed restriction, sex and their interaction were mainly observed in the nutritional value of meat, while physical measurements of meat were negligibly affected. The interaction between feed restriction and sex affected the cross-sectional area of muscle fibre only in rabbits and nutrias. The data indicated the relationships between compensatory growth, muscle fibre distribution, and nutritional value of meat.
