title: Effect of cassava bioethanol by-product and crude palm oil in Brahman x Thai native yearling heifer cattle diets: II. Carcass characteristics and meat quality.
abstract: This experiment was conducted to determine the effects of cassava bioethanol by-product (CEP) and crude palm oil (CPO) on the carcass characteristics and meat quality of yearling heifer cattle. Eighteen crossbred Brahman × Thai heifers were randomly allotted to 2 × 3 factorial arrangement consisting of two levels of CEP (15 or 30 %, LCEP or HCEP) and 3 levels of CPO (0, 2, and 4 %). The results obtained showed that lean meat was greater (P < 0.05) in HCEP-fed cattle, but bone percentage and lean/bone ratio were less (P < 0.05) than LCEP-fed cattle. Carcass fat (P < 0.05) and fat content (P < 0.01) were significantly increased with levels of dietary CPO. Diets with 4 % CPO supplementation had better effects on redness (a*, P < 0.01) and chroma (C*, P < 0.001) values. In conclusion, up to 30 % CEP can be used to improve lean carcass and 4 % CPO can improve the redness of the meat.
