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.
