Adding sand to the compound feed can increase the weight of the broiler because the use of such feed to feed the chicken can increase the amount of sand in the stomach and increase the feed utilization. According to experiments, 8% of sand is added to the broiler compound feed, and each chicken can gain 325 grams. The experiment also showed that when 7% of the sand was added to the broiler compound feed, the broiler gained weight significantly. If 9% of the sand was added, the chicken not only did not gain weight, but also caused the weight to fall. Therefore, adding 8% of sand to the broiler compound feed is the best ratio for broiler weight gain.
