摘  要：
试验研究不同蛋氨酸铬水平对肉猪生长性能、饲料表观消化率、血清生化指标的影响。试验采用单因子试验设计,选用40 kg左右杜长大三元杂生长猪96头,随机分为4个组,其中1个对照组,3个试验组,试验组分别添加200、300、400μg/kg(以含铬量计算)的蛋氨酸铬;试验结果表明:1在生长性能方面:以200μg/kg蛋氨酸铬日增重最高,比对照组提高了12.37%(P<0.05);料重比最低,比对照组低4.13%(P<0.05)。2在饲料消化率方面:蛋氨酸铬水平对生长猪饲料表观消化率无显著影响,200μg/kg蛋氨酸铬组能量、粗蛋白、粗脂肪的消化率均高于对照组,但均未达到显著水平(P>0.05)。3在血清生化指标方面:200、300、400μg/kg蛋氧酸铬组总蛋白、球蛋白相对于对照组均有提高,其中200μg/kg组在总蛋白方面显著高于对照组(P<0.05),300μg/kg组在球蛋白方面显著高于对照组(P<0.05);血糖值与对照组相比均有所下降,其中300μg/kg组与对照组相比差异显著(P<0.05);200μg/kg组的胆固醇显著低于对照组(P<0.05);低密度脂蛋白各组数据均显著下降(P<0.05)。在血清免疫指标方面,200μg/kg蛋氨酸铬组Ig G与对照组相比有所提高(P>0.05),试验组皮质醇出现下降趋势,但结果不显著(P>0.05)。由试验结果可知,蛋氨酸铬在日粮中添加剂量为200μg/kg时对提高生长猪的生长性能是最有利的。

摘  要：
This experiment was conducted to study the effects of different chromium methionine levelson growth performance,apparent digestibility,serum biochemical indicators of growing pigs.A total of96 growing pigs with similar weight(± 40 kg) were divided into 4 groups randomly.There were 4groups' diets containing 0,200,300,400 μg/kg chromium methionine respectively.The result showed:1 growth performance: 200 μg/kg group got more average daily gain,12.37% higher than the controlgroup(P<0.05),F/G was the lowest,4.13% lower that the control group(P<0.05).2 feed digestibility:200 μg/kg group's digestibility was higher than the control group on energy,crude protein,and crudefats,without reaching the significant level(P>0.05).3 serum biochemical indicators:compared with thecontrol group,200,300,400 μg/kg chromium methionine intake increased the TP and globulin ofgrowing pigs.The TP concentration of 200 μg/kg group was significantly higher than the control groupand the globulin concentration of 300 μg/kg group were significantly higher than the control group par-ticularly.The blood sugar level significantly decreased in 300 μg/kg group compared with controlgroup.200 μg/kg group did it well in cholesterollevel and Ig G level decreasing and reached a sig-nificant level(P<0.05) compared with controlgroup.In summary,it was concluded that chromi-um methionine had best effect on growth performance of growing pigs when the addition of 200 μg/kg in diet.
