本研究的目的是提供一些信息的影响，户外牧场（O）与室内（I）相比，淘汰母猪的胴体和肉品质。来自同一育种单位的12头母猪（每组6头）在末次断奶后11天屠宰。O母猪的胴体较重且较肥，但背最长肌（L）和肱三头肌（TB）肌肉中的脂肪含量不受影响。放牧O母猪导致n−3脂肪酸含量的大幅增加，特别是背膘和L肌中的C18：3亚麻酸，从而改善了肉的营养品质。维生素E含量出现（P=0.13）增加，在背膘的O母猪，但不是在肌肉。在储存过程中的肉类脂质氧化组之间是相似的。组织学和代谢观察表明，户外饲养增加了L肌肉的糖酵解能力，和TB的氧化能力。室外饲养不影响肉的pH值和pH值，但降低了TB的颜色（a值和B值），并增加了里脊肉加工成腊肉的产量。室外饲养降低了红色强度和均匀性，但提高了嫩度。
The objective of this study was to provide some information on the influence of outdoor rearing on pasture (O) compared with indoor (I) on carcass and meat quality of cull sows. Twelve sows (6 per group) originating from the same breeding unit were slaughtered 11days after their last weaning. O sows had heavier and fatter carcasses, however lipid content in Longissimus (L) and Triceps brachii (TB) muscles was not affected. Grazing of O sows led to a high increase in the n−3 fatty acid content, particularly the C18:3 linolenic acid in the backfat and L muscle, thus improving the meat nutritional quality. Vitamin E content appeared (P=0.13) to be increased in the backfat of O sows, but not in the muscles. Lipid oxidation in meat during storage was similar between groups. Histological and metabolic observations showed that outdoor rearing increased the glycolytic capacity of the L muscle, and the oxidative capacity of the TB. Outdoor rearing did not influence meat pH1 and pHu, but decreased colour (a∗and b∗values) of the TB, and increased the processing yield of loin into cured bacon. Outdoor rearing decreased the red colour intensity and homogeneity, but improved tenderness of cured loins.
