Effect of Different Feed Supplements on Growth Performance of Broiler Chickens

Thesis Abstract

Abstract
The poultry industry is constantly seeking ways to improve growth performance and overall health of broiler chickens to meet the increasing demand for poultry products. This study aimed to investigate the effect of different feed supplements on the growth performance of broiler chickens. The research was conducted over a period of 12 weeks, during which broiler chickens were fed with various feed supplements including probiotics, prebiotics, organic acids, enzymes, and herbal extracts. The growth performance parameters assessed included body weight gain, feed intake, feed conversion ratio, and mortality rate. The introduction section provides a background to the study, highlighting the importance of optimizing feed formulations to enhance broiler growth performance. The problem statement identifies the gaps in existing research regarding the use of different feed supplements in broiler diets. The objectives of the study were to evaluate the impact of various feed supplements on growth performance and to determine the most effective supplementation strategy. Limitations of the study, scope of research, significance of findings, and definitions of key terms are also discussed in the introduction chapter. The literature review chapter presents a comprehensive analysis of previous studies related to feed supplementation in broiler diets. Ten key themes were identified, including the role of probiotics in gut health, the impact of prebiotics on nutrient absorption, the effectiveness of organic acids as growth promoters, and the potential benefits of herbal extracts in improving immunity. The review of literature provided a theoretical framework for the current study and highlighted the gaps in existing knowledge. The research methodology chapter outlines the experimental design, sample size calculation, data collection methods, and statistical analysis techniques used in the study. Eight key contents were discussed, including the selection of broiler chickens, formulation of experimental diets, measurement of growth performance parameters, and data analysis procedures. The methodology chapter ensured the rigor and validity of the research findings. The discussion of findings chapter presents a detailed analysis of the results obtained from the study. The impact of different feed supplements on growth performance parameters was evaluated, and significant differences among treatment groups were identified. The discussion also explores the mechanisms through which feed supplements exert their effects on broiler chickens and provides insights into optimal supplementation strategies. In conclusion, this study provides valuable insights into the effect of different feed supplements on the growth performance of broiler chickens. The findings suggest that certain supplements can significantly improve body weight gain, feed efficiency, and overall health of broilers. The implications of these results for the poultry industry are discussed, highlighting the potential benefits of optimizing feed formulations to enhance broiler productivity and profitability.
