日粮中添加红花油对生长育肥猪生产性能和胴体品质的影响

研究日粮中添加不同水平的红花油对生长育肥猪生长性能和胴体品质的影响．日粮中添加红花油水平分别为0，0．4％，0．6％，0．8％和1％．结果表明：添加红花油的各试验组的平均日增重、粗蛋白、粗脂肪、粗纤维等消化率显著提高（P〈0．05），饲料利用率得到改善；各试验组猪的屠宰率和瘦肉率显著高于试验组1，眼肌面积、脂肪酸含量也比试验组1得到提高，降低了胆固醇含量，改善了猪肉品质．

Effect of safflower oil on growth performance and meat quality in finishing pigs

Evaluated the effect of dietary different safflower oil on growth performance and carcass quality of growth-finishing pig. The dietary of safflower oil level is 0,0.4%, 0. 6% ,0.8% and 1.0%. The results indicated that the average daily gain of the testing groups were significantly greater than treatment 1 group; the using rate of feed was improved; the apparent rate of assimilation was increased; the slaughter rate and lean meat percentage of the testing groups were significantly greater than treatment 1 group; the eye muscle area was improved; the fatty acid content was increased; the cholesterol content was reduced; the quality of pork was improved.
