Resumo: | The objective was to evaluate the empty body components of cull cows slaughtered at different weights. It was used 43 Purunã cull cows mean age of 68.02 ± 17.36 months. The experimental design used was the completely randomized. The slaughter weights studied were 401, 434, 461, 476 and 522 kg. Empty body weight and yield increased 65.16 g and 0.0253% for each kg increased in body weight, respectively. The increase slaughter weight promoted linear increase of the absolute amount of noncarcass components. The weight of the gastrointestinal tract increased to 9.61 g per kilogram over the weight of slaughter, not being changed by the independent variable when expressed as percentage of empty body. The absolute and relative weight of internal organs varied linearly positive and negative with increasing slaughter weight, respectively. The increase in slaughter weight resulted in a linear increase of the set of internal fat, both expressed in kg and percentage of empty body. The set of external components increased 8.6 g per kilogram of slaughter weight increase. The increase in slaughter weight above the minimum requirements by refrigerators reduces the efficiency of the production system, due to the increased proportion of non-carcass components. |

Utilizaramse 43 vacas da raça Purunã com idade média de 68,02 ± 17,36 meses. O delineamento experimental utilizado foi o inteiramente casualizado. Os pesos de abate estudados foram de 401, 434, 461, 476 e 522 kg. O peso e o rendimento de corpo vazio responderam linearmente à elevação do peso de abate, aumentando 65,16 g e 0,0253% a cada quilograma acrescida, respectivamente. O aumento do peso de abate proporcionou aumento linear da quantidade absoluta dos componentes não carcaça. O peso do trato gastrointestinal aumentou 9,61 g a cada quilograma acrescida no peso de abate, não sendo alterado pela variável independente quando expresso em percentagem do corpo vazio. O peso absoluto e peso relativo do conjunto de órgãos internos variou de forma linear positiva e negativa, respectivamente, com o avanço do peso de abate. O aumento do peso de abate proporcionou aumento linear do conjunto de gorduras internas. O conjunto de componentes externos aumentou 8,6 g a cada quilograma acrescida no peso de abate. A elevação do peso de abate, acima das exigências mínimas dos frigoríficos, prejudica a eficiência do sistema produtivo, em virtude do aumento proporcional dos componentes não carcaça.UEL2013-05-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionabomaso, couro, fígado, rúmen, trato gastrointestinalapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1105010.5433/1679-0359.2013v34n2p883Semina: Ciências Agrárias; Vol. 34 No. 2 (2013); 883-894Semina: Ciências Agrárias; v. 34 n. 2 (2013); 883-8941679-03591676-546Xreponame:Semina.
