| 摘 要： | 将540只1日龄樱桃谷鸭随机分为3组,每组6个重复,每重复30只,分别饲喂添加0(对照组)、200、400 mg·kg-1乳化剂的试验日粮,试验期为42 d,研究不同含量乳化剂对樱桃谷鸭生长性能、肌肉品质和脂类代谢的影响.结果表明:添加400 mg·kg-1乳化剂可显著降低樱桃谷鸭前期料重比(P<0.05),提高42 d体重(P<0.05);添加200 mg·kg-1乳化剂可显著降低胸肌48 h滴水损失(P<0.05),提高胸肌24 h的pH(P<0.05).与对照组和200 mg·kg-1乳化剂组相比,添加400 mg·kg-1乳化剂可显著提高血清中的甘油三酯(TG)含量(P<0.05).添加200 mg·kg-1乳化剂可显著降低血清中的低密度脂蛋白胆固醇(LDL-C)含量(P<0.05),添加乳化剂对血清中的高密度脂蛋白胆固醇(HDL-C)、极低密度脂蛋白胆固醇(VLDL-C)和血清中的总胆固醇(TC)含量均无显著影响(P>0.05).结果提示,日粮中添加400 mg·kg-1乳化剂可提高樱桃谷鸭生产性能,添加200 mg·kg-1可改善胸肌肌肉品质,添加不同含量乳化剂均能不同程度改善脂类代谢.

| Abstract: | The objective of this experiment was to study the effect of different levels of emulsifier on growth performance,meat quality and lipid metabolism in Cherry Valley ducks.540 one-day-old Cherry Valley ducks were randomly distributed into 3 treatments,each of which had 6 replicates of 30 ducks per pen.Ducks were fed a basal diet supplemented with 0(control group),200,400 mg·kg-1 emulsifier respectively.The experiment last for 42 days.The results showed that basal diet supplemented 400 mg·kg-1 emulsifier significantly decreased feed: gain ratio(P<0.05) in starter period and increased 42 d body weight of ducks(P<0.05).Ducks fed 200 mg·kg-1 emulsifier had a lower 48 h drip loss(P<0.05) and a higher pH24 h of breast muscle(P<0.05) compared with the control.Serum triglyceride(TG) in ducks fed 400 mg·kg-1 emulsifier group was higher than that in the other two groups(P<0.05).200 mg·kg-1 emulsifier significantly decreased serum low density lipoprotein cholesterol(LDL-C)(P<0.05).There were no significant differences in high density lipoprotein cholesterol(HDL-C),very low density lipoprotein cholesterol(VLDL-C),total cholesterol(TC) in the serum and TC in liver(P>0.05).In conclusion,supplementation of 400 mg·kg-1 emulsifier can increase the growth performance of Cherry Valley ducks.Supplementation of 200 mg·kg-1 emulsifier can improve breast muscle quality.Supplementation of different levels of emulsifier can both improve the lipid metabolism of Cherry Valley ducks. |
