辣木梗叶对奶牛生产性能及血浆生化、抗氧化和免疫指标的影响
Effects of Moringa oleifera Leaves and Peduncles on Production Performance, and Plasma Biochemical, Antioxidant and Immune Indexes in Dairy Cows
摘要
Abstract
The aim of this experiment was to investigate the effects of Moringa oleifera leaves and peduncles replaced 50％ alfalfa in basal diet on production performance, plasma biochemical, antioxidant and immune indexes in lactating dairy cows.Eight healthy and multiparous Holstein cows (same or similar in body weight,parity and milk production, at 100 to 150 d after deliver) were allocated to two groups and make a crossover trail.Cows in experimental (A) group were fed diet which Moringa oleifera leaves and peduncles replaced50％ alfalfa in a basal diet, and those in control (B) group were fed the basal diet.There were two periods in this study, and each period had 15 days of pretrial period and 3 days of trail period.Blood and milk samples were collected, and dry matter intake (DMI) and milk production were recorded.The results showed as follows: 1) compared with B group, DMI in A group was significantly increased (P<0.05), and milk production had a tendency to rise (0.05 ≤ P<0.10), and A group significantly improved milk protein rate, milk protein yield and milk total solid content, while milk somatic cell count had a tendency to decrease (0.05 ≤ P<0.10);2) the contents of cholesterol (CHOL) and triglyceride (TG) in plasma of A group were significantly lower than those of B group (P<0.05), and alkaline phosphatase (ALP) activity and non-esterified fatty acid(NEFA) content of A group had tendencies to decrease (0.05 ≤ P<0.10);3) compared with B group, A group not only significantly improved total antioxidant capacity (T-AOC) and inhibition of hydroxyl radical capacity in plasma (P< 0.05), significantly decreased the content of malonaldehyde (MDA) in plasma (P <0.05), and significantly increased plasma content of immunoglobulin G (IgG) (P<0.05).In conclusion,Moringa oleifera leaves and peduncles can promote the improvement of production performance of dairy cows to a certain extent, prevent the happening of mastitis, and improve plasma biochemical indexes, antioxidant function and immune function, and can be applied in production practice of dairy cows as a high quality roughage.[Chinese Journal of Animal Nutrition, 2017, 29 (2) : 628-635]关键词
