Resumo: | This study aimed to evaluate the effect of slaughter weight on animal performance, carcass commercial cuts and meat characteristics of Purunã cows feedlot finished. We used 28 cull cows with 68.02±17.36 months of age slaughtered at different weights (461, 476, 434 and 522 kg). The experimental design was completely randomized with four treatments (slaughter weight) and seven replicates (animals). The dry matter intake, expressed as kg d-1 and % of body weight, presented quadratic variation with increasing slaughter weight, with the highest values observed for slaughter weight of 461 kg. The average daily gain decreased linearly, whereas the absolute weight of forequarter, short ribs, and pistol cut linearly increased by the advance of slaughter weight. In relative terms only the short ribs was changed by increase slaughter weight, increasing linearly. Between the proportions of meat cuts prepared for commercialization, linear increases were observed for the chuck and striploin. Increasing slaughter weight promoted linear increases in the scores of color, marbling and palatability, but did not alter the score of tenderness of the meat. The increase of slaughter weight of cull cows of the Purunã breed reduces animal performance, increasing the losses by trimming fat, with important benefits only for the meat palatability. |

Objetivou-se avaliar o efeito do peso de abate sobre o desempenho animal, cortes comerciais da carcaça e características da carne de vacas Purunã terminadas em confinamento. Foram utilizadas 28 vacas de descarte com 68,02±17,36 meses de idade abatidas com pesos distintos (434; 461; 476 e 522 kg). O delineamento experimental foi o inteiramente casualizado com quatro tratamentos (pesos de abate) e sete repetições (animais). O consumo de matéria seca, expresso em kg dia-1 e % do peso corporal, apresentou variação quadrática em função do avanço do peso de abate, sendo os maiores valores observados para o peso de abate de 461 kg. O ganho de peso médio diário diminuiu linearmente, enquanto que o peso absoluto do dianteiro, ponta de agulha e traseiro especial aumentou linearmente com avanço do peso de abate. Em termos relativos somente o corte ponta de agulha foi alterado pelo avanço do peso de abate, aumentando linearmente. Entre as proporções dos cortes cárneos preparados para comercialização, elevações lineares foram verificadas para o acém e contra filé. O aumento do peso de abate promoveu incrementos lineares nos escores de coloração, marmoreio e palatabilidade, mas não alterou a maciez da carne. O avanço do peso de abate de vacas de descarte da raça Purunã reduz o desempenho animal, aumentando as perdas pelo recorte de gordura, com benefícios importantes apenas para a palatabilidade da carne.
