摘要: 【目的】研究不同硒源对鹅生产性能、屠宰性能、肉品质、肌肉常规养分、免疫和抗氧化功能的影响。【方法】试验选用1日龄健康、体重相近的肉鹅96只(P>0.05),按单因素完全随机设计分为对照组、亚硒酸钠组、酵母硒组和纳米硒组4组,每组3个重复,每个重复8只;对照组饲喂基础日粮,其它3组分别在基础日粮中添加0.3 mg•kg-1水平的亚硒酸钠、酵母硒和纳米硒。【结果】除9周龄酵母硒组胸肌率、腿肌率显著高于对照组外(P<0.05),4、9周龄其余各试验组鹅的体增重、料重比、屠宰性能指标均与对照组差异不显著(P>0.05),且不同硒源间对鹅的生产性能也无显著性影响(P>0.05)。9周龄肌肉失水率、硬度、水分、粗脂肪、灰分含量各试验组显著低于对照组(P<0.05),不同硒源间差异不显著(P>0.05);各试验组滴水损失显著低于对照组(P<0.05),且酵母硒组显著低于亚硒酸钠组(P<0.05);肌红蛋白含量各试验组显著高于对照组(P<0.05),酵母硒组显著高于亚硒酸钠组(P<0.05);各试验组粗蛋白含量显著高于对照组(P<0.05),且酵母硒和纳米硒组显著高于对照组(P<0.05),但不同硒源间差异不显著(P>0.05)。除9周龄亚硒酸钠组、纳米硒组脾脏指数与对照组差异不显著外(P>0.05),第4、9周龄其余各试验组胸腺指数、脾脏指数、法氏囊指数均显著高于对照组(P<0.05),但不同硒源间差异不显著(P>0.05);第4、9周龄T淋巴细胞转化率与对照组相比,亚硒酸钠组、纳米硒组均显著提高(P<0.05),酵母硒组极显著提高(P<0.01),且酵母硒组显著高于亚硒酸钠组(P<0.05)。各试验组4、9周龄血清与肝脏中谷胱甘肽过氧化物酶(GSH-PX),总超氧化物歧化酶(T-SOD)和总抗氧化能力(T-AOC)活力均显著高于对照组(P<0.05);各试验组4、9周龄血清与肝脏中丙二醛(MDA)和过氧化氢(H2O2)均显著低于对照组(P<0.05);不同硒源的4周龄试验肉鹅血清中GSH-PX活力差异不显著(P>0.05),4周龄肝脏、9周龄血清和肝脏酵母硒组均显著高于亚硒酸钠组(P<0.05);4、9周龄试验肉鹅血清与肝脏中的T-SOD活力差异不显著(P<0.05);4、9周龄血清,4周龄肝脏酵母硒组T-AOC均显著高于亚硒酸钠组(P<0.05),9周龄肝脏纳米硒组显著高于亚硒酸钠组(P<0.05);MDA含量,4、9周龄血清与肝脏酵母硒组均显著低于亚硒酸钠组(P<0.05);4、9周龄血清与肝脏H2O2含量差异不显著(P<0.05)。亚硒酸钠和纳米硒组cGPx基因在肝脏中的表达量显著高于对照组(P<0.05);酵母硒组极显著高于对照组(P<0.01),酵母硒组显著高于亚硒酸钠和纳米硒组(P<0.05)。【结论】日粮中添加不同硒源对鹅的生产性能和屠宰性能无显著性影响(P>0.05),但是能够改善鹅的肉品质和鹅肌肉的营养成分含量,增加机体免疫功能和抗氧化能力;酵母硒比亚硒酸钠和纳米硒的作用更为显著。

Abstract: 【Objective】 The objective of the experiment is to study the effect of different selenium sources on production performance, slaughter performance, meat quality, muscles conventional nutrients,immune function and anti-oxidation function in goose.【Method】Ninety-six one-day-old geese with similar initial body weight (P>0.05) were divided into 4 groups with three replications per group according to a completely random design. The proportion of selenium in the same basal diets was 0.30 mg•kg-1, respectively. The control group was fed with basal diet, the other three groups was fed with basal diet added with sodium selenite (SS), Se-enriched yeast (SY) and Nano-Se, respectively.【Result】Except that breast muscle percentage and leg muscle rate index of SY group were much higher than the control group (P<0.05), the body weight gain, feed conversion ratio and slaughter performance index of 4 and 9-week-old goose in other groups were no obvious difference (P>0.05), and there was no obvious difference in different selenium sources (P>0.05). The water loss rate, hardness, water content and crude fat content index of 9-week-old goodse in other groups were lower than the control group (P<0.05), and there was no obvious difference in different selenium sources (P>0.05). The drip loss of other groups were lower than the control group (P<0.05), the drip loss of SY was lower than SS (P<0.05). The mypglobin content of other groups were higher than the control group (P<0.05), the mypglobin content of SY was higher than SS (P<0.05). The crude protein content of SY and Nano-Se were higher than the control group (P<0.05), and there was no obvious difference in different selenium sources (P>0.05). Various selenium sources increased significantly in immune function of goose, except that spleen index of Nano-Se group compared with the control group was no obvious difference, the immune organ index of 4 and 9-week-old of other groups were much higher than the control group (P<0.05), but there was no obvious difference in different selenium sources.Tlymphocyte transformation rate of Nano-Se group and 4, 9 week-old of SS group were all much higher than the control group (P<0.05), SY group were much higher than SS group (P<0.05) and very higher than the control group (P<0.01). The activity of GSH-PX, T-SOD and T-AOC among various selenium sources both in 4, 9w serum and liver increased significantly (P<0.05). The content of MDA and H2O2 reduced significantly both in 4, 9w serum and liver (P<0.05). There was no difference in the activity of GSH-PX among various selenium sources in 4w serum of geese (P>0.05). Compared with those geese fed by SS, the activity of GSH-PX in serum (9w) and liver (4, 9w) fed by SY increased significantly (P<0.05). There was no difference in the activity of T-SOD among various selenium sources both in 4, 9w serum and liver of geese. The activity of T-AOC in 4, 9w serum and 4w liver fed by SY significantly increased (P<0.05); the activity of T-AOC in 9w liver fed by Nano-Se very significantly increased (P<0.05). The content of MDA in 4, 9w serum and liver fed by SY very significantly reduced (P<0.05). There was no difference in the content of H2O2 among various selenium sources both in 4, 9w serum and liver (P>0.05). The cGPx gene expression of the SS and Nano-Se group were significantly higher than the control group (P<0.05), the SY group was very significantly higher than the control group (P<0.01), the SY group was higher than the SS group and Nano-Se group (P<0.05).【Conclusion】Adding different selenium sources to the diet of goose has no significant effects on production performance and slaughter performance, but can improve the quality of goose and content of muscles conventional nutrients, and promote the immune, antioxidant capacity. Compared with SS and Nano-Se, SY is a better source of selenium for goose.
