Thesis Abstract

Abstract
The assessment of weight gain between indigenous and exotic breeds of broiler chickens is crucial in understanding the performance and potential economic returns associated with different genetic strains. This study aimed to compare the growth and weight gain characteristics of indigenous and exotic broiler breeds under similar management conditions. A total of 200 broiler chickens, comprising 100 indigenous breed and 100 exotic breed, were used in the experiment. The birds were raised in a controlled environment with similar feed, water, and management practices provided to both groups. The results indicated significant differences in weight gain between the indigenous and exotic broiler breeds throughout the growth period. The exotic breed demonstrated faster weight gain compared to the indigenous breed from the early stages of growth. At the end of the study period, the exotic broilers had a significantly higher average body weight compared to the indigenous broilers. This difference in weight gain can be attributed to genetic factors influencing growth rates and feed conversion efficiency in the two breeds. Furthermore, feed conversion ratio (FCR) was evaluated to determine the efficiency of feed utilization by the two breeds. The exotic broilers exhibited a lower FCR compared to the indigenous broilers, indicating better feed efficiency in converting feed into body weight. This finding is consistent with the observed higher weight gain in the exotic breed and highlights the economic advantage of using exotic breeds for commercial broiler production. In conclusion, this study provides valuable insights into the weight gain differences between indigenous and exotic broiler breeds. The results suggest that exotic breeds have superior growth performance and feed efficiency compared to indigenous breeds under similar management conditions. These findings have implications for poultry farmers and breeders in selecting suitable genetic strains for broiler production based on growth characteristics and economic considerations. Further research is recommended to explore the underlying genetic mechanisms influencing weight gain in different broiler breeds and to optimize breeding strategies for enhanced performance and profitability in the poultry industry.
