Effects of Dietary Supplementation of Arginine on Growth Performance of Broiler Chickens

Abstract

The purpose of this research added arginine to increase the growth of broiler chickens in Nangarhar University, Agriculture research farm in Afghanistan, study discovered Over 96 one-day broiler chickens in 42 days based on the record of their daily behaviors, Hence, record of the chickens have divided into Four groups, each group being divided into three replications. Each replication of each group consisted of eight chickens, the first group was control and the other three were treatment groups, such as, in T1 group (0.1%) on the arginine Dose given, the second T2 group 0.2% arginine was added to the Dose, and T3 group added arginine (0.3%) through the factor of FCR such as Weight gain, feed intake. Nevertheless, by statistical analysis, that Null hypothesis is fail to rejected, p-value is greater than 0.05 means there is no significant change amongst with the experimental groups in the first three weeks and also in the control group as well as at the fourth, fifth, and sixth weeks, P value is less than 0.05, hence Null hypothesis is rejected (Type 1error), there is a significant difference between the treatment groups and the control group. Furthermore, all group feed conversion ratio (H0) is rejected. Study emphasized that’s adding 0.3 per cent of arginine to daily diet chickens increase weight by less consumed feed as well reduce of mortality rate. According to this study, it is recommended that 0.3% arginine should be added to the chicken diet after the third week, to gain more weight by consuming a small amount of diet.
