Comparative Analyses of Beef Quality of Commercial Cattles
摘要
Abstract
In order to analyze the beef quality of commercial catties, 108 commercial catties were selected randomly to compare their meat quality. Acording to cattle's weights, 108 catties were arranged to four groups with 401 kg below, 40l~500 kg, 501~600 kg, 601 kg above. Comparative analysis found that although carcass weight of four groups showed significant difference (P< 0. 01), no significant difference existed in dressing percentage(P>0. 05); the beef color were deeper and the fat color were more whiter and shearing force were smaller (P> 0. 05) with age and weight increase. There was no significant marbling trend (P>0. 05) in different weight groups. Backfat thickness were thicker with the weight increase between two groups(401 kg below and 501~600 kg) (P<0. 05). The greater the catties weight, the eye-muscle area were larger and there were significant difference between 401 kg below and other groups(P< 0. 01). The greater the weight,the more split meat weight(P<0. 01). The results showed that the commercial catties' weight were heavier , the beef quality were better.关键词
