“…Likewise, Tarouco et al (2007) and Silva et al (2012) among others all support the primary importance of body weight in the prediction of weights of HQRTP. Similarly, Huerta-Leidenz et al (2018) found that HCW was the first variable in importance in regression models to explain HQRTP. Other traits that entered the models accounted for relatively little additional variation but improved goodness-of-fit.…”

“…Generally, carcass and ultrasound data show a similarly coefficient of determination with weight of edible cuts, however, when data were presented as a percentage basis the relationship become weaker (Dinkel et al, 1965;Tarouco et al, 2007;Silva et al, 2012;Sakamoto et al, 2014;Huerta-Leidenz et al, 2018). The authors consider unnecessary the estimate the sample size of HQRTP % because the low model fit to this trait (data not showed).…”

“…There is also interest in yield (composition) of the carcass and retail product. Despite longstanding recognition of the inadequacy of percentages as measures of composition (Weil, 1962;Miller and Weil, 1963;Dinkel et al, 1965;Sakamoto et al, 2014;Huerta-Leidenz et al, 2018), such practice has been commonplace in studies similar to this one. Here, use of regression on SBW or HCW with variation in the deviations from the regression is advocated as being indicative of differences among animals in composition.…”

“…The sample size is the main problem when carcass studies are performed, not only for research but also for the industry. Studies that have provided predictions of an amount and a yield of carcass cuts from live and ultrasound measurements perform both carcass and ultrasound data (Tait et al, 2005;Tarouco et al, 2007;Silva et al, 2012;Sakamoto et al, 2014;Huerta-Leidenz et al, 2018), however, the number of animals necessary to do the researches are high (102 to 466) and the sample size to determine the maximum model fit was not determinate.…”

“…As these experiments are equivalent in inferential power, efficient use of resources obligates the least cost paradigm. Numerous equations were identified for a large number of different end points under widely varying sets of experiments (Hedrick, 1983, Tait et al, 2005Silva et al, 2012;Sakamoto et al, 2014;Huerta-Leidenz et al, 2018).…”

Two hundred seventeen grass-finished Braford steers were assessed by ultrasonic scanning and subsequently harvested with their pistol hindquarters fabricated into boneless wholesale cuts. The Longissimus thoracis muscle area and subcutaneous fat depths were measured. The objectives of this study were: 1) to develop prediction equations for weights of the pistol hindquarter and high-value commercial cuts, and 2) to estimate sample size needed for experiments comparing pistol hindquarter retail product weight using either physically or ultrasonically measured carcass traits. Carcass measurements explained 44 % to 94 % of the variation in weights of individual cuts, whereas, measurements that were made using ultrasound explained 42 % to 90 % of the variation in the weights. Models used to predict the weight of pistol hindquarter retail product with carcass measures and ultrasound measures showed high coefficient of determination (R 2 = 0.92 and 0.97, respectively). Whether based on carcass or ultrasound measures, models used to estimate weight percentage of fat trimmed from the pistol hindquarter had lack of fit. In general, models for individual cuts weights that used traits measured with ultrasound as independent variables approached the accuracy of models using carcass traits. Thus, only slightly greater samples sizes were required to have equivalent power to detect differences in retail product weights using ultrasound measures. For experiments of equivalent power, differences in the number of animals required may be offset by avoiding costs for slaughter and fabrication.

The objective of this work was to assess the effect of genetic group and heterosis on the relationship between body weight and morphometric measurements, in purebred and crossbred animals from the second (G2) and third (G3) generations of Nellore and Charolais calves. Body weight (BW), average daily weight gain (ADG), foreleg circumference (FC), thoracic girth (TG), body length (BL), and croup height (CH) were measured at birth and at 63, 210, and 365 days of age in animals from G2 and G3. Charolais animals were superior to Nellore ones for gains BW, ADG, BL, and TG, as well as for the ratio between BW gain and CH gain; Nellore animals were superior for CH gains. Crossbred animals of both generations were superior to the purebred animals for gains of BW, BL, and CH. In G2, the predominance of Charolais genes resulted in greater gains of BW, ADG, FC, and TG. The G3 animals were superior to the purebred animals for ADG, FC, and TG. No differences were found for the ratio between gains of weight and morphometric measurements. Heterosis and complementarity are apparent for weight and body measurements of crossbred calves from rotational crossings.
