Predicting beef carcass cutability.
Analyses were conducted to develop and test the efficacy of beef carcass cutability prediction equations. Data from 1,602 calf-fed steer carcasses (Germplasm Utilization Project; GPU) were used to develop the equations and an additional 1,160 calf-fed steer carcasses (Germplasm Evaluation Project; GPE) were used to validate the equations. In both experimental groups, USDA yield grade ranged fro...
متن کاملPrediction of Percent Retail Product, Retail Product Weight and Hot Carcass Weight From Serially Measured Live Animal Traits
A total of 1,072 observations collected over a six-year period were used to develop prediction models for retail product (percentage and weight) and hot carcass weight from live cattle measures. Independent variables used were: ultrasound fat thickness (UFAT), ultrasound longissimus muscle Area (ULMA), age, hip height (HT), live weight (WT), ultrasound-predicted percent Intramuscular fat (UIMF)...
متن کاملBeef Carcass Appraisal
Carcass assessment in Australia, and probably in most beef producing countries of the world, has been, and still is, in the hands of a relatively few specialists actively engaged in the meat industry. These specialists from long experience determine reasonably quickly and accurately by eye the desirable and undesirable features of a carcass. In competitions a point score system has been applied...

متن کاملPrediction of retail beef yield and fat content from live animal and carcass measurements in Nellore cattle.
Data from 156 Nellore males were used to develop equations for the prediction of retail beef yield and carcass fat content, expressed as kilograms and as a percentage, from live animal and carcass measurements. Longissimus muscle area and backfat and rump fat thickness were measured by ultrasound up to 5 d before slaughter and fasted live weight was determined 1 d before slaughter. The same tra...
