Effects of different feed additives on growth performance and health of broiler chickens

Thesis Abstract

Abstract
The poultry industry plays a critical role in meeting the global demand for high-quality protein sources. In this context, the growth performance and health of broiler chickens are of utmost importance to ensure sustainable production practices. This study aimed to investigate the effects of different feed additives on the growth performance and health of broiler chickens. The research was guided by the following objectives to assess the impact of various feed additives on the growth performance of broiler chickens, to evaluate the effects of feed additives on the health status of broiler chickens, and to determine the optimal combination of feed additives for maximizing growth and health outcomes in broiler chickens. A comprehensive literature review was conducted to explore existing knowledge on feed additives and their potential effects on broiler chicken production. The review highlighted the importance of nutrition in poultry health and performance, emphasizing the role of additives such as probiotics, prebiotics, enzymes, and organic acids in improving growth and immunity in broiler chickens. The research methodology involved the design and implementation of a controlled feeding trial with different groups of broiler chickens receiving varying feed additive treatments. Key parameters such as body weight gain, feed conversion ratio, mortality rate, and immune responses were measured to assess the impact of feed additives on growth performance and health outcomes. The findings of the study revealed significant differences in growth performance and health indicators among the different treatment groups. Certain feed additives demonstrated positive effects on body weight gain, feed efficiency, and immune responses, indicating their potential as growth promoters and health enhancers for broiler chickens. The discussion of the results provided insights into the mechanisms underlying the effects of feed additives on broiler chicken physiology and metabolism. Factors such as gut health, nutrient utilization, and immune function were identified as key determinants of growth performance and health in broiler chickens, highlighting the importance of targeted nutritional strategies in poultry production. In conclusion, this study contributes valuable information to the field of animal science by elucidating the effects of different feed additives on the growth performance and health of broiler chickens. The findings have practical implications for poultry producers seeking to optimize feed formulations and enhance the overall productivity and well-being of broiler chicken populations. Further research is warranted to explore additional feed additive combinations and dosages for maximizing the growth and health outcomes of broiler chickens in diverse production settings.
