Effects of Fermented Compound Chinese Herbs on Serum Biochemical,Antioxidant and Reproductive Hormone Indices of Dairy Cows in Late Pregnancy
The objective of this study was to investigate the effects of compound Chinese herbs after fermenta-tion with probiotics and its effects on serum biochemical,antioxidant and reproductive hormone indices of dairy cows in late pregnancy.The fermented compound Chinese herbs were prepared using Bacillus subtilis and Sac-charomyces cerevisiae.Twenty-four healthy Holstein dairy cows in late pregnancy were randomly divided into 3 groups with 8 replicates in each group and 1 cow in each replicate.Cows in 3 groups were fed basal diets sup-plemented with 0(control group),1％and 2％fermented compound Chinese herbs,respectively.The pretest period lasted for 15 days,and the experimental period lasted for 45 days.The results showed as follows:1)compared with the unfermented compound Chinese herbs,the crude protein and crude fiber contents in fermen-ted compound Chinese herbs were significantly increased(P＜0.01).2)Compared with the unfermented com-pound Chinese herbs,the total polysaccharides,total flavonoids and total saponins contents in fermented com-pound Chinese herbs were significantly increased(P＜0.01),however,the total phenolics content was signifi-cantly decreased(P＜0.01).3)Compared with the control group,dietary supplemented with 1％fermented compound Chinese herbs significantly increased the serum high density lipoprotein cholesterol content of dairy cows(P＜0.05),and significantly decreased the serum aspartate aminotransferase activity(P＜0.05).4)Compared with the control group,dietary supplemented with 1％fermented compound Chinese herbs signifi-cantly increased the serum glutathione peroxidase activity of dairy cows(P＜0.05);dietary supplemented with 1％and 2％fermented compound Chinese herbs significantly increased the serum total antioxidant capacity of dairy cows(P＜0.05 or P＜0.01),and significantly decreased the serum malondialdehyde content(P＜0.05).5)Compared with the control group,dietary supplemented with 1％and 2％fermented compound Chinese herbs significantly increased the serum progesterone content of dairy cows(P＜0.05),and significantly de-creased the serum estradiol content(P＜0.05 or P＜0.01);dietary supplemented with 2％fermented compound Chinese herbs significantly increased the serum luteinizing hormone content(P＜0.05).In conclusion,the bio-logical activity of compound Chinese herbs is improved after fermentation with probiotic.Dietary supplemented with probiotic fermented Chinese herbs can regulate the reproductive hormone contents and enhance antioxidant capacity of dairy cows in late pregnancy.[Chinese Journal of Animal Nutrition,2024,36(4):2434-2444]
