Effects of Fumarate on Nutrient Apparent Digestibility, Rumen Volatile Fatty Acid Contents, Serum Biochemical Parameters and Reproductive Performance of Goats in Later Pregnancy
摘要
Abstract
The aim of this study was to investigate the effects of fumarate on nutrient apparent digestibility, ru-men volatile fatty acid content, serum biochemical parameters and reproductive performance of goats in later pregnancy. Twenty Xiangdong black goats in pregnancy 90 d, weighed ( 36. 5 ± 2.5) kg and aged between 2 and 3 years, were randomly divided into 2 groups, each group contained 10 goats. Goats in 2 groups were fed the basal diet ( control group) and basal diet supplemented with 2% fumarate ( fumarate group) , respectively. The pre-experimental period lasted from 90 to 95 d in pregnancy, and the experimental period lasted from 95 d in pregnancy to birth of young goats. The results showed that compared with the control group, the nutrient feed intake and apparent digestibility of goats in later pregnancy of fumarate group were no significant change ( P>0.05) ; on 2. 5 h after feeding, the acetate, propionate, total volatile fatty acid contents and propionate percentage in rumen were significantly increased ( P<0.05) , the acetate to propionate ratio was significantly decreased ( P<0.05); the contents of malondialdehyde, estradiol and estriol in serum were significantly de-creased ( P<0.05) , the prolactin and progesterone contents and catalase activity in serum were significantly in-creased ( P<0.05) ; the body weight gain of ewes during later pregnancy tended to increase (0.05≤P<0.10) , the total birth weight of lambs was significantly increased ( P<0.05) . In conclusion, diet supplemented with 2% fumarate can increase total volatile fatty acid content of goats in later pregnancy, and shift fermentation pathways from acetate to propionate, and improve the body antioxidant capacity, body weight gain of ewes during later pregnancy gain and total birth weight of lambs.[Chinese Journal of Animal Nutrition, 2019, 31 (2) :850-857]关键词
