The aim of this study was to investigate the effect of a preparation of black goji berry branches () on growth performance, meat quality, amino acid and fatty acid content of sheep.
The experiment was a one-way completely randomized trial, in which 40 male sheep of the F1 generation of Dupo × Lake sheep crosses at four months of age were randomly divided into four groups of ten lambs each. Each group was fed an isoenergetic and isonitrogenous total mixed pellet ration containing 0% (CON), 10% (H1), 20% (H2) and 30% (H3) of branches. The experimental period included a pre-test adaptation of 10 d and an experimental test period of 60 d.
The Luminosity of each experimental group was highly significantly higher than that of the CON ( < 0.01). The values for Redness of the H2 and H3 groups were significantly higher than that of the CON ( < 0.05). The gamma-aminobutyric acid (GABA) concentration in the longest back muscle first increased and then decreased ( < 0.01), and the H2 group was extremely significantly higher than the CON and the other experimental groups. The H1 and H2 groups were significantly lower than the control group, decreasing by 6.87% and 7.07%, respectively ( < 0.05). The c20:0, c20:1 content showed a linear increase with increasing addition of but the difference was not significant ( > 0.05).
Thus, dietary feed supplementation with 20% of dried, ground branches can improve sheep meat quality and culture benefit.
本研究旨在探讨黑枸杞枝条制剂对绵羊生长性能、肉质、氨基酸和脂肪酸含量的影响。
本试验为单因素完全随机试验，选取40只4月龄的杜泊×湖羊F1代雄性绵羊，随机分为4组，每组10只羔羊。每组饲喂等能量、等氮的全混合颗粒日粮，分别含有0%（CON）、10%（H1）、20%（H2）和30%（H3）的黑枸杞枝条。试验期包括10天的预试适应期和60天的试验期。
各试验组的亮度均极显著高于对照组（P<0.01）。H2组和H3组的红度值显著高于对照组（P<0.05）。最长背肌中γ-氨基丁酸（GABA）浓度先升高后降低（P<0.01），H2组极显著高于对照组和其他试验组。H1组和H2组显著低于对照组，分别降低了6.87%和7.07%（P<0.05）。c20:0、c20:1含量随黑枸杞枝条添加量的增加呈线性增加，但差异不显著（P>0.05）。
因此，日粮中添加20%的黑枸杞干枝条粉可改善羊肉品质，提高养殖效益。
