摘要
以白来航蛋鸡和爱拔益加肉鸡为研究对象,研究了蛋鸡与肉鸡小肠早期生长发育规律的差异。在相同条件下以同一饲料饲喂两种鸡公雏,在出雏当天以及出雏后1、3、7、14和28日龄分批屠宰测定,测量小肠总长度及总重量,并保留空肠中段样本,制作小肠显微切片,对两个品种仔鸡的小肠早期发育的几个主要指标进行测量,并运用线形回归的方法将所得的数据进行分析比较。使用正大521蛋小鸡饲料饲喂的白来航蛋仔鸡和爱拔益加肉仔鸡,其肠道的各项指标均呈增长趋势,且爱拔益加肉仔鸡小肠的增重增长生长发育较白来航蛋鸡快。
To study the pattern of the early growth and development of layer and broiler,small intestinal developmental morphology of two commercial breeds： White Leghorn layer and Arbor Acres broiler were measured from day of hatch to 28 days.Chickens were fed with the same feeds under the same condition.At day of hatch,day 1,3,7,14 and 28,birds were sampled,the intestine growth traits were measured and the intestine samples were stored for slides.Some intestine traits were measured with microscope by using image software.The results showed that the weight,length,perimeter of the small intestine,intestinal villus length,and intestinal recesses depth of two breeds increased with days of age,and the growth rate of AA broiler was faster than that of White Leghorn layer.The difference in intestinal growth and development between layers and broilers was analyzed in this study,and the results can be used for future research.
