摘要: 试验旨在研究补饲女贞子对泌乳奶牛生产性能及血液生化指标的影响。选择48头健康的泌乳中期中国荷斯坦奶牛,随机分成4组,每个处理组12头奶牛,对照组饲喂全混合日粮(TMR),N1、N2、N3组分别在饲喂TMR日粮的基础上补饲150、300、450 g/d女贞子。预试期1周,正试期7周。结果表明,与对照组相比,补饲450 g/d女贞子可显著提高泌乳奶牛4%校正乳产量(P<0.05),补饲150 g/d女贞子可显著提高泌乳奶牛乳脂含量(P<0.05),而对泌乳奶牛干物质采食量、产奶量及乳蛋白、总固形物含量和体细胞数均无显著影响(P>0.05);与对照组相比,补饲女贞子可显著降低泌乳奶牛血液中甘油三酯含量(P<0.05),而对其他血液生化指标均无显著影响(P>0.05)。综上所述,补饲女贞子具有提高泌乳中期奶牛生产性能、改善机体脂类代谢的作用。

Abstract: The objective of the experiment was to investigate the effect of supplementation of Ligustrum lucidum Ait on production performance and blood biochemical indices in dairy cows.Forty eight mid-lactation Holstein dairy cows were randomly assigned to four groups with twelve individuals in each group.The control group was fed a TMR diet,groups N1 to N3 were fed the TMR diets supplemented with 150,300,450 g/d Ligustrum lucidum Ait,respectively.The pre-test period lasted for 1 week and the trial period lasted for 7 weeks.The results showed that compared with control group,the supplementation of 450 g/d Ligustrum lucidum Ait significantly increased 4% FCM (P<0.05),the supplementation of 150 g/d Ligustrum lucidum Ait significantly increased milk fat content (P<0.05).Dietary supplementation of Ligustrum lucidum Ait had no effects on DMI,milk yield,milk protein,total solids (TS) and somatic cell counts (SCC) (P>0.05).Compared with control group,the supplementation of Ligustrum lucidum Ait significantly decreased blood TG content (P<0.05),and had no effects on other blood biochemical indices (P>0.05).In conclusion,dietary supplementation of Ligustrum lucidum Ait could improve milk quality and yield,and the lipid metabolism of dairy cows.

Key words: Ligustrum lucidum Ait; production performance; blood biochemical indices; dairy cows
