摘要
使用发酵和提取两种不同工艺加工的杜仲产品作为饲料添加剂,探究其对雏鸡增重、免疫球蛋白及生化指标的影响。选择2日龄、健康和体重相近的海兰白雏鸡90只,随机分为3组,每组30只,分别为对照组(饲喂基础饲料)、精粉组(饲喂基础日粮+0.6%杜仲叶发酵物)、提取物组(饲喂基础日粮+1%杜仲叶提取物),进行2个月的饲喂试验。结果表明,精粉组鸡的平均体重显著高于提取物组与对照组(P<0.05);精粉组与提取物组的血清总蛋白、球蛋白与甘油三酯指标结果均高于对照组;精粉组和提取物组的氨基酸总量与鲜味氨基酸含量均显著高于对照组(P<0.05);精粉组与提取物组鸡的血清球蛋白含量高于对照组。通过将两种不同的杜仲产品作为饲料添加剂饲喂幼龄鸡,发现杜仲叶发酵物与提取物相比,有更强地促进幼龄鸡的增重、改善肉品质和提高免疫球蛋白的功效。
In this experiment,two different products-fermentation and extraction of Eucommia ulmoides were used as feed additives to explore the effects on the growth performance,immunity and meat quality of chicks.90 chicks of two months old which are healthy and have similar weights were selected and divided into three groups which are control group(basic feed)and purified powder group(basic diet+0.6%Eucommia leaf fermentation),extraction group(basic diet+1%Eucommia leaf extraction)respectively,and groups are fed for two months.The results showed that the average body weight of chicks in purified powder group was significantly higher than that in extraction group and control group(P<0.05);Similarly,three indexes of total protein,globulin and triglyceride in extraction group and purified powder group were higher than that in control group;the total amount of amino acids and umami amino acid content of extraction group and purified powder group were remarkably higher than those of control group(P<0.05);the serum globulin content of the chicks in extraction group and purified powder group was higher than that of control group.In conclusion,after feeding with two different Eucommia products,It was found that the fermented product of Eucommia leaves has better effect of promoting the growth of young chicks,improving meat quality and immunity compared with the extracted product.
