【摘要】：为研究育肥方式对滇南小耳猪脂肪酸含量的影响以生产优质猪肉,按规模化养殖、"吊架子"和"全放养加补饲"等3种育肥方式进行滇南小耳猪育肥试验,测定其背最长肌、背脂、腹脂的脂肪酸含量。结果显示:农村"吊架子"育肥组和"全放养加补饲"育肥组油酸、单不饱和脂肪酸、饱和脂肪酸含量分别比规模化养殖育肥组高2.27%、0.86%、9.19%(P0.01)和9.46%、9.34%、7.23%(P0.01),亚油酸、亚麻酸、多不饱和脂肪酸、不饱和脂肪酸含量分别比规模化养殖育肥组低24.30%、83.62%、31.00%、6.90%(P0.01)和49.65%、71.19%、51.33%、5.41%(P0.01)。"吊架子"育肥和"全放养加补饲"育肥会导致滇南小耳猪油酸、饱和脂肪酸和单不饱和脂肪酸升高,亚油酸、亚麻酸和多不饱和脂肪酸降低。对滇南小耳猪等地方猪种,在产区条件许可时可适当选用"吊架子"乃至"全放养加补饲"的育肥方式以生产高油酸、低亚油酸的优质保健型猪肉以提高养殖效益。
[Abstract]:In order to study the effect of fattening mode on fatty acid content in southern Yunnan small ear pig, the experiment of fattening was carried out in south Yunnan small ear pig according to three fattening methods, such as large scale breeding, "hanging shelf" and "full stocking plus supplementary feeding", and the longest muscle of the back was measured. Fatty acid content in backfat and abdominal fat. The results showed that the contents of oleic acid, monounsaturated fatty acid and saturated fatty acid were 2.27% and 0.86% higher in the "hanging shelf" group and "full-stocking plus supplementary feeding" group than those in the large-scale fattening group, respectively. 9.19% (P0.01) and 9.46%, 9.34%, 7.23% (P0.01). The contents of linoleic acid, linolenic acid, polyunsaturated fatty acids and unsaturated fatty acids were 24.30% and 83.62% lower than those of large-scale fattening group, respectively. "31.00%, 6.90% (P0.01) and 49.65%, 71.19%, 51.33%, 5.41% (P0.01)." "fattening" and "full-stocking plus supplementary feeding" could lead to the increase of fatty acid, saturated fatty acid and monounsaturated fatty acid, while the decrease of linoleic acid, linolenic acid and polyunsaturated fatty acid in southern Yunnan. For the local pig breeds such as Yunnan small ear pig, the fattening mode of "hanging shelf" and "full-stocking plus supplementary feeding" can be selected properly when the conditions of producing area are permitted to produce high-oil and low-linoleic acid high-quality health-care pork to improve the efficiency of breeding.
