γ-氨基丁酸对夏季生长肥育猪血清生化指标的影响

将48头体重43kg左右的"杜×长×大"三元杂交猪随机分成两组,饲喂在基础日粮中添加0、10mg/kgGABA的日粮。结果表明:添加GABA使血清中钙、磷、钾、氯4种无机离子浓度提高,差异不显著(P>0.05);总蛋白、白蛋白、尿素氮水平有提高趋势,差异不显著(P>0.05),葡萄糖水平提高13.29%,差异显著(P<0.05);丙氨酸转氨酶、天门冬氨酸转氨酶活性上升,差异不显著(P>0.05),乳酸脱氢酶、肌酸磷酸激酶活性分别下降16.93%(P<0.05)、38.22%(P<0.01);谷胱甘肽过氧化物酶(GSH-Px)、超氧化物歧化酶(SOD)活性均有上升,其中GSH-Px差异极显著(P<0.01),丙二醛含量下降(P>0.05)。

Effect of gamma-aminobutyric acid on serum biochemical parameter of finishing hogs in summer

48 Duroc×(Landrace×Large White) finishing hogs that weighed about 43 kilograms were randomly divided into two groups, one was fed with basal diet, and the other was fed with basal diet added 10 mg/kg GABA. The results showed that in 10 mg/kg GABA group, serum calcium, phosphorus, kalium, chloride concentrations were increased respectively, all the differences were not significant(P>0.05); so were the serum total protein, albumin, urea nitrogen concentrations have the improvements uptrend, but the differences were not significant(P>0.05); glucose was significantly increased by 13.29%(P<0.05); GPT, GOT activity were both not significantly increased, while LDH and CPK were decreased by 16.93%(P<0.05), 38.22%(P<0.01); GSH-Px, SOD activity were increased, while MDA concentration was decreased.
