摘要
将20头杜长大肥育猪随机分成试验组和对照组,试验组日粮添加200μg·kg-1烟酸铬(以Cr元素计)作85天饲喂试验。结果表明:(1)试验组日增重比对照组提高10.9%;料重比下降6%。(2)添加烟酸铬对血清中钾、钠、氯化物、镁、总蛋白、白蛋白、高密度脂蛋白、谷草转氨酶、谷丙转氨酶、乳酸脱氢酶、α-羟丁酸脱氢酶、直接胆红素、总胆红素、IgG、IgM无影响(P>0.05);血清中钙、磷、铁、葡萄糖、尿素氮、尿酸、甘油三脂、总胆固醇、血红蛋白、磷酸肌酸激酶和肌酐的含量显著下降;碱性磷酸酶含量显著升高(P<0.01)。(3)猪体组织Cr含量均未超过国家限量标准。(4)猪体各器官组织正常。由此可见,在生长肥育猪中添加一定量铬制剂对猪有正面效应。
Twenty 3-way crossbred[Duroc ×(Landrace ×Yorkshire)] growing /finishing pigs were equall y divided into the test group and control group.The test group was fed the basal diet supplemented with 200ug·kg-1 chromium from chromium nicotinate.Whole feeding trial lasted for 85days.The results showed as follows:(1)The daily gain and ratio of feed to gain of test group were 10.9%and 6%higher than those of the control,respectively.(2)No effect was found on serum potassium,sodium,chloride,magne-sium:iron total protein,albumin,Highdensity lipoprotein(HDL),glutamic -oxaloacetic transaminase(GOT),glu-tamic -pyruvic transaminase(GPT),lactic dehydrogenase,a -hydroxybutyric dehydrogenase,d irect bilirubin,total bilirubin,IgG and IgM in test group(P>0.05);but serum calcium,inorganic phosphate,urea nitrogen,uric acid,triglyceride,total cholesterol,c reatine phosphate kinase(CPK)and creatinine in test group decreased significantly(P<0.05)as compared to the control;serum alk aline phos-phatase in test group was also marked ly increased(P<0.01).(3)The chromium residues in tissues were de-termined to be not exceeding the limi tation of national standard.(4)No histological change was found in t he tis-sues of the tested organs.It is concluded that adding a certain amount of chromium nicotinate to prg' s diet had a beneficial effect.
