Resumo: | Forty-one carcasses of culled cows were used, averaging eight and a half years. The main objective in the study was to establish the relationship among weight and percentage of forequarter, rib and dorsal cuts with measurements taken on the carcasses. Measurements were: warm carcass weight, conformation, covering fat thickness, leg length, carcass length, deepness, width and area of the longissimus dorsi muscle, weight and percentage of forequarter, rib and dorsal cuts. Main regression equations were: forequarter cut weight = 1.94 + 0.16 (weight of warm carcass), with an r2 = 0.58 (P <0.01); forequarter cut percentage = 37.69 - 2.17 (deepness of longissimus muscle) + 0.72 (width of longissimus muscle), with an r2 = 0.17 (P <0.05); rib cut weight = - 0.27 + 0.06 (warm carcass weight), with an r2 = 0.50 (P <0.01); rib cut percentage = 15.62 - 0.73 (width of longissimus muscle) + 1.23 (deepness of longissimus muscle), with an r2 = 0.20 (P <0.05); dorsal weight = 0.81 + 0.24 (weight of warm carcass), with an r2 = 0.92 (P <0.01) and dorsal percentage = 5.22 + 0.62 (deepness of longissimus muscle) - 2.64 (fat thickness) + 0.01 (warm carcass weight) - 0.09 (leg length), with an r2 = 0.07 (P >0.05). The results permit to conclude: 1. Warm carcass weight is the main measurement to estimate weight of forequarter, rib and dorsal cuts. 2. These carcass measurements do not precisely estimate the percentage of cuts. |

The results permit to conclude: 1. Warm carcass weight is the main measurement to estimate weight of forequarter, rib and dorsal cuts. 2. These carcass measurements do not precisely estimate the percentage of cuts. Foram utilizadas 41 carcaças de vacas de descarte com idade média de 8.5 anos. O trabalho objetivou estabelecer relações entre pesos e percentagens dos cortes dianteiro, costilhar e serrote com medidas realizadas na carcaça. Mediram-se: peso da carcaça quente, conformação, espessura da gordura de cobertura, comprimento da perna e da carcaça, profundidade, largura e área do músculo longissimus, peso e percentagem dos cortes serrote, dianteiro e costilhar. Principais equações de regressão obtidas: peso dianteiro = 1,94 + 0,16 (peso carcaça quente), com r2 = 0,58 (P <0,01): percentagem dianteiro = 37,69 - 2,17 (profundidade do músculo longissimus) + 0,72 (largura músculo longissimus), com r2 = 0,17 (P <0,05); peso costilhar = -0,27 + 0,06 (peso carcaça quente), com r2 = 0,50 (P <0,01); percentagem costilhar = 15,62 - 0,73 (largura músculo longissimus) + 1,23 (profundidade músculo longissimus), com r2 = 0,20 (P <0,05); peso serrote = 0,81 + 0,24 (peso carcaça quente), com r2 = 0,92 (P <0,01) e percentagem serrote = 52,22 + 0,62 (profundidade músculo longissimus) - 2,64 (espessura gordura de cobertura) + 0,01 (peso carcaça quente) - 0,09 (comprimento da perna), com r2 = 0,07 (P >0,05). Conclui-se que: 1) o peso da carcaça quente é a principal medida para estimar o peso da carcaça quente é a principal medida para estimar o peso dos cortes dianteiro, costilhar e serrote. 2) As medidas de carcaça aqui realizadas não estimam com precisão a percentagem dos cortes.
