| Summary: | -. I 1) compared with the association of LMACWT with WT and .83) than were corresponding ratios of longissimus area per (r = -.23 to .09) than corresponding LMACWT ratios (r = -.28 45.4kg of live weight(LMACWT)(r=.50 to .66). K ratios were and .83, respectively). K ratios had significantly lower and used to calculate ratios of ULMA and WT that have greater appropriate measure of evaluating ULMA data in purebred at yearling and at a post-yearling time period. Principles breeding programs where carcass traits are included as part bulls for the purpose of validating the results in phase 1. K calculate non-linear ratios (K) of ULMA to WT using the Correlations between K ratios and WT were at least 50% less correlations with WT (r = -. 17) and yearling age (YAGE) (r = correlations with WT and YAGE (r = -. 0 1 and -. 0 8, corresponding linear ratios and may provide a more data were collected at weaning, during a 140 day gain test, formula K = ULMA / WT.6869 for each ultrasound test interval. In Phase 1, growth performance and serial ultrasound data independence from the effects of weight and age than K ratios were more highly correlated with ULMA (r = .79 to linear regression of ULMA on WT yielded a growth coefficient logarithmic transformation of the pooled serial data, the not highly correlated with age (r = -. I 1 to .23). of the allometric equation were used and following of the selection process. ratios were highly correlated with LMACWT and ULMA (r = .97 respectively) and a high correlation (r = .9 1) with ULMA. Results indicated that allometric equations can be developed to -.46).In Phase 11, growth performance and yearling ultrasound data were collected and analyzed on 1,831 Brangus using a growth coefficient of .50 resulted in lower value of .6869. The coefficient value .6869 was used to were collected and analyzed on 194 Brangus bulls. Ultrasound YAGE (r = -.43 and .26, respectively). K ratios calculated |
