Abstract

This study was conducted to investigate the effects of a traditional Chinese herbal medicine complex (TCHMC) on the productive performance of periparturient dairy cows. Eighteen non-lactating pregnant Holstein dairy cows with similar body conditions with 1 to 2 parity were randomly divided into three groups (n = 6), receiving a basal diet with 0 (CON group), 200 (T-200 group), and 300 (T-300 group) g TCHMC per day from 14 to 9 days prepartum. The results demonstrated that TCHMC treatments decreased the days of gestation, calving to first service, and calving to first visible estrus. Compared with CON at specific time points, TCHMC treatments increased the concentrations of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2), whereas progesterone (P4) and E2 concentrations decreased. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and creatine kinase (CK) concentrations were downregulated, whereas that of globulin (GLB) and immunoglobulin G (IgG) were upregulated by TCHMC treatments around the time of calving. Compared with CON and T-200 treatments, the T-300 treatment increased the serum concentrations of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), catalase (CAT) and total antioxidant capacity (T-AOC) and decreased the malondialdehyde (MDA) concentration from 7 d prepartum to 21 d postpartum when. In addition, although TCHMC treatment had no effect on average birth weight, heart rate, respiratory rate, and body temperature of calves, the T-300 treatment increased serum albumin (ALB) and IgG concentrations in calves from 3 to 14 days postpartum. The addition of TCHMC used in the present study could serve as a potential effective strategy to improve the health and productive performance of periparturient dairy cows, and the optimal dose should be set at 300 g per day.

中草药复合物补充剂改善围产期奶牛的繁殖性能、血清生化指标和抗氧化能力

摘要

本研究旨在调查中药复方 (TCHMC) 对围产期奶牛生产性能的影响。将 18 头体况相似、1-2 胎的非泌乳妊娠荷斯坦奶牛随机分为 3 组(n  = 6),分别接受 0 头(CON 组)、200 头(T-200 组)和 300 头基础日粮。 (T-300 组)产前 14 至 9 天每天 g TCHMC。结果表明,TCHMC 治疗减少了妊娠天数、产犊到第一次服务和产犊到第一次可见的发情期。与特定时间点的 CON 相比,TCHMC 治疗增加了促卵泡激素 (FSH)、黄体生成素 (LH) 和雌二醇 (E 2 ) 的浓度,而黄体酮 (P4 ) 和 E 2浓度下降。血清丙氨酸氨基转移酶 (ALT)、天冬氨酸氨基转移酶 (AST) 和肌酸激酶 (CK) 浓度被下调,而球蛋白 (GLB) 和免疫球蛋白 G (IgG) 在产犊时被 TCHMC 处理上调。与 CON 和 T-200 处理相比,T-300 处理增加了谷胱甘肽过氧化物酶 (GSH-Px)、超氧化物歧化酶 (SOD)、过氧化氢酶 (CAT) 和总抗氧化能力 (T-AOC) 的血清浓度,并降低了丙二醛(MDA)浓度从产前7 d到产后21 d时。此外,虽然 TCHMC 治疗对小牛的平均出生体重、心率、呼吸频率和体温没有影响,但 T-300 治疗在产后 3 至 14 天增加了小牛的血清白蛋白 (ALB) 和 IgG 浓度。
