N-氨甲酰谷氨酸与牛磺酸对公猪精液品质、血清激素指标及精浆抗氧化能力的影响
Effects of N-Carbamyl Glutamate and Taurine on Semen Quality, Serum Hormone Parameters and Antioxidant Capacity of Breeding Boars
摘要
Abstract
This study was conducted to determine the effects of dietary supplementation of N-carbamyl gluta-mate ( NCG) and taurine ( Tau) on semen quality, serum hormone parameters, seminal plasma protein content and antioxidant capacity of breeding boars. Twenty 18-month-old Yorkshire boars with similar weight healthy were randomly divided into 4 groups with 5 replicates per group and 1 pig per replicate. Pigs were fed basal diet ( control group) , basal diet+0.2% NCG ( NCG group) , basal diet+0.6% Tau ( Tau group) , basal diet+0.2%NCG+0.6% Tau ( NCG+Tau group) . The trial lasted for 100 days. The results showed as follows: 1) com-pared with the control group, dietary supplemented with NCG, Tau and NCG+Tau significantly decreased the ejaculation reaction time (P<0.01), and significantly increased the ejaculation time (P<0.01). The main effects analytic result showed that during 56 to 100 days, dietary supplemented with NCG significantly im-proved the semen volume ( P<0.05) , dietary supplemented with NCG or Tau+NCG significantly improved the sperm motility ( P<0.05) , dietary supplemented with NCG significantly decreased the percentage of abnormal sperm (P<0.05). 2) Compared with the control group, during 56 to 100 days, dietary supplemented with NCG or NCG+Tau significantly improved serum follicle stimulating hormone ( FSH) content ( P<0.01) , diet-ary supplemented with NCG+Tau significantly improved the content of luteinizing hormone ( LH) and testos-terone (T) in serum (P<0.01). 3) The main effects analytic result showed that dietary supplemented with NCG significantly improved seminal plasma total protein ( TP) content ( P<0.05) , dietary supplemented with Tau significantly improved seminal plasma albumin (ALB) content (P<0.05). 4) The main effects analytic result showed that during 56 to 100 days, dietary supplemented with NCG significantly improved total antioxi-dant capacity ( T-AOC) and glutathione peroxidase ( GSH-Px) activity in seminal plasma ( P<0.05) , dietary supplemented with Tau or NCG+Tau significantly improved seminal plasma superoxide dismutase ( SOD) ac-tivity ( P<0.05) . Analyze the data synthetically, dietary supplemented with NCG and Tau can regulate the ser-um hormone secretion level, help to increase the sexual desire, and improve the protein quality in seminal plas-ma, as well as the antioxidant capacity and the quality of semen.关键词
