Final answer:
The supplement mentioned in a research paper on Broiler chicks growth probably refers to their nutrition, as nutritional supplements play a significant role in the growth and health of broiler chickens.
Step-by-step explanation:
The most likely focus of the supplement mentioned in a research paper on the topic of Broiler chicks growth would be B. Broiler Chickens' Nutrition. This is because the growth of broiler chicks is heavily influenced by their nutritional intake, and research often aims to optimize feed composition to maximize growth rates while maintaining health.
Various supplements can be added to the feed to improve chick growth, such as vitamins, minerals, amino acids, and even probiotics. These supplements are designed to enhance the broilers' feed conversion ratio, which is the effectiveness with which the chickens convert feed into body weight. Studies on broiler chick growth typically involve trials comparing different feed formulations, measuring outcomes such as weight gain, feed efficiency, and overall health status.
