The use of feed raw materials from corn and rice planted in soil mixed with flue-gas desulfurization gypsum in broiler diet

Abstract

The study on the effect of feed raw materials from corn and rice planted in soil mixed with flue-gas desulfurization gypsum in broiler diet, was conducted in 144 male newly hatched broiler chicks with the group T-test separated into 2 experimental groups, 6 replicates of 12 chicks.Group 1, the chickens were fed a control diet without feed raw materials from corn and rice planting in soil mixed with flue-gas desulfurization gypsum (Control). Group 2, the chicks were fed diets containing feed raw materials from corn and rice planting in soil mixed with flue-gas desulfurization gypsum (Gypsum). The experimental period was 5 weeks. The nutrient compositions of corn, broken rice and rice bran were analyzed. The growth performance, carcass and meat quality, heavy metal residues in breast meat and blood chemistry were observed. The results showed that the protein content in the corn and broken rice was lower than that of the general corn meal and broken rice, and the protein content in the rice bran was not different from that of the general rice bran. The growth performance, carcass quality, meat quality and blood chemistry showed no significant difference (P>0.05). The heavy metal residues in breast meat were not found in both groups. Therefore, corn and rice planted in soil mixed with flue-gas desulfurization gypsum can be considered safe and viable sources of raw materials for animal feed.
