“…The study by Tuitoek 7 found that altering dietary protein concentrations between 10-14% CP affected egg weight while Cho 8 reported no increase in egg weight in commercial layers offered diets with protein between 15% and 19.5% CP. Gous 9 reported that the effect of altering the dietary amino acid concentrations was more severe on egg production than on egg weight.…”

The present study was conducted on growth and laying performance of indigenous chicken fed ration with different crude protein at Bunda campus students` farm. Nutrition remains one of the challenges that indigenous chickens experience under smallholder management system. The birds are dependent on scavenging feed resources which is associated with inadequate nutrition and chickens sometimes are supplemented with maize bran and left over's depending on the availability. Little has been done to determine the nutrition requirements of indigenous chickens. Therefore, the objective of this study was to evaluate effects of different protein levels on growth and laying performance of IC specifically to determine optimal protein requirement of indigenous chickens and assessing the growth and laying performance of the indigenous chicken. The study used repeated measure design where 7 day old chickens weighing 590±73g were randomly allocated to diets containing different levels of proteins and each pen contained 13 chicks each. The diets were fed to the chicks at ad lib and the amount given increased with the increase in the growth of the chickens. Water was also provided at ad lib. The collected data were analyzed using mixed model of SAS 2010. Significance was declared at P<0.05 and means were separated using PDFF option of SAS software. In addition, SPSS software was used to compare the means. The results from the study have shown that there was an increase (P<0.05) in live weight in the chickens fed 180g/kg CP compared to those fed 170 and 190g/ kg CP. laying percentage was high in chicken fed 18g/kg CP and Egg weight with increasing from 35.93-43.18 with decrease in protein levels (P<0.05). The diet that contained 17g/kg had the highest egg weight compared to the other two diets.
