Resumo
The direct determination of carcass and empty body composition as experimental routine, despite being the most accurate method, is time consuming, laborious and expensive. Therefore, indirect methods have been developed to estimate on quick, simple, economical and reliable ways for the compositions of carcass and empty body of beef cattle. This study aimed to obtain the correlations among the compositions of 9-10-11th ribs, carcass and empty body for protein, fat, ashes and water contents, expressed in percentage and kilograms, in young Nellore bulls. Sixty-seven non-castrated Nellore bulls were randomly selected for confining period in two consecutive years (2008 and 2009) and were confined in individual pens for approximately 100 days, until they reached a subcutaneous fat thickness of 4 mm over the Longissimus muscle. They were slaughtered at an average age of 540 days and body weight of 398 kg. Chemical analysis of the 9-10-11th ribs, carcass and empty body were carried for protein, fat, ashes and water. The 9-10-11th ribs cut was obtained according to Hankins and Howe (1946). Carcass composition was obtained after grinding, homogenizing, sampling, analyzing and combining edible portions and bones. Empty body composition was obtained after grinding, homogenizing, sampling, analyzing, and combining blood, hide, head + feet, viscera, and carcass.
