【摘要】：旨在研究饲粮中不同甜菜碱水平对三元育肥猪血清中TP、BUN、IgG含量和ChE活性的影响。选取60头3月龄左右、体重相近(49kg±4.04kg)的杜大长三元杂交育肥猪,随机分为4组,对照组饲喂基础饲粮(无甜菜碱),试验组分别饲喂在基础饲粮中添加1 000、1 500、2 000mg/kg甜菜碱的试验饲粮。饲喂试验前后前腔静脉采集抗凝血液,分离血清,全自动生化分析仪测定血清中TP、IgG、BUN含量和ChE活性,应用SPSS23.0软件进行统计学处理与分析。结果表明,3个水平甜菜碱对三元育肥猪血清中BUN含量和ChE活性无显著影响(P0.05);3个水平甜菜碱可显著提高血清TP含量(P0.05);在1 500mg/kg甜菜碱水平下,饲喂前后TP与IgG含量变化与对照组相比极显著升高(P0.01);饲粮中甜菜碱添加量为1 500mg/kg时饲喂效果最好,可促进三元育肥猪蛋白质合成代谢、提高其免疫力,是育肥猪饲粮甜菜碱最适添加量。
[Abstract]:The purpose of this study was to study the effects of different betaine levels in diet on the ChE activity and the content of TPBUNN in serum of three yuan fattening pigs.Sixty 3-month-old Dudachang three-way crossbred fattening pigs were randomly divided into 4 groups. The control group was fed with basal diet (without betaine), the experimental group was fed with 1 000 ~ 1 500kg / 2 000mg/kg betaine in the basal diet.The anticoagulant blood was collected from the anterior vena cava before and after feeding and the serum was separated. The content of ChE and the activity of ChE in the serum were measured by automatic biochemical analyzer. The results were analyzed by SPSS23.0 software.The results showed that three levels of betaine had no significant effect on the BUN content and ChE activity in the serum of three-way fattening pigs, but three levels of betaine could significantly increase the serum TP content (P 0.05), and at the level of 1 500mg/kg betaine, the three levels of betaine had no significant effect on the content of BUN and the activity of ChE.The changes of TP and IgG contents before and after feeding were significantly higher than those in the control group (P 0.01), and the dietary betaine supplementation of 1 500mg/kg had the best effect, which could promote protein synthesis metabolism and enhance immunity of the three yuan fattening pigs.It is the optimum addition amount of betaine in the diet of fattening pigs.
