“…Retail beef cut percentage is a major economical interest especially to beef salers. Prediction of retail beef yield or the ratio with respect to carcass weight costs high and cannot be made accuarately because it should be made after partition process of beef carcasses and because it varies by cutting process especially trimming of fat (Abraham et al, 1980;Murphey et al, 1983;Schackleford et al, 1995). Therefore, effective prediction should be made at the time of carcass evaluation that has to make carcasses to have merchandizable value.…”

Two sets of data on carcass traits and beef cut parameters were used to investigate the relationships between carcass and beef cut measurements, which can be used to make predictions of retail cut percentages. One set had a total of 1,141 measurements of Hanwoo cattle of three different sex origins, which were slaughtered in an abattoir located at the National Institute of Animal Science, RDA, Korea from 1996 to 2008. To develop prediction models for retail cut percentage with higher accuracies than the current model, another set consisting of a total of 13,389 records of carcass and beef cut traits were collected from 30 abattoirs and butcheries in Korea from 2008 to 2009. Bulls yielded heavier and leaner carcasses than steers. High correlation coefficients were estimated between amount of body fat and percent retail cut (-0.82) as well as between back fat thickness (BF) and percent retail cut (-0.62). The amount of retail cut, however, was highly correlated with body weight before slaughter (BW, 0.95) or with cold carcass weight (CWT, 0.94). Relationships between percent retail cut and measurable beef yield traits, BF, loin eye area (LEA) or CWT varied by sex class, which must be considered for development of a prediction model with high accuracy. Models of data for all breeds and sexes fit the effects of breed, sex, and interaction of abattoir by butchers, whereas models of data for each breed and sex fit the effect of interaction of abattoir by butcher only. Due to possible future changes in back fat control, we performed a log transformation of BF. Our new models fit better than the currently used model.

“…También se observó una variación moderada de la CONFORMACION (33,99%), pero, el resto de los rasgos de la canal presentó coeficientes de variación menores que 15%. La escasa variación de las medidas corporales (longitudes y áreas) y la amplia variación de los indicadores de grasa corporal han sido reportadas por otros autores (Abraham et al, 1980;Huerta-Leidenz & Morón, 1996;Huerta et al, 1997;Atencio 2001) para búfalos y bovinos.…”

“…Las experiencias en el desarrollo de ecuaciones predictivas del rendimiento en cortes, basadas en técnicas de regresión múltiple, para clasificar por rendimiento carnicero, se han reportado en Estados Unidos (Abraham et al, 1980;Shackelford et al, 1995), Australia (Hopkins & Roberts, 1995), Europa (Muldowney et al, 2001), Asia (Lee et al, 2005), Latinoamérica (Jardim et al, 1991;Amador-Gómez & Palacios-Gómez, 1994;Atencio, 2001;Schindler et al, 2004). Sin embargo, estas experiencias también han servido para demostrar que las ecuaciones obtenidas para un determinado grupo comercial de ganado vacuno, muchas veces no son extrapolables a otras regiones con animales en diferentes condiciones tanto intrínsecas como ambientales.…”

Los objetivos de este estudio fueron determinar la asociación entre rasgos de la canal y el rendimiento en cortes (RCD), rendimiento en hueso y recortes de grasa en búfalos de agua, y desarrollar ecuaciones predictivas para cada variable mencionada. Se utilizaron 48 búfalos de agua (24 castrados y 24 enteros), sacrificados a los 17, 19 y 24 meses de edad con mestizaje de razas Murrah y Mediterránea. Se evaluaron las variables de la canal y del rendimiento en cortes. Se realizaron: pruebas descriptivas, análisis de correlación, residuos y de regresión lineal múltiple. En los castrados, el acabado de grasa y la circunferencia del muslo explicaron la mayor variación en RCD. El espesor de grasa y el porcentaje de grasa renal fueron las variables mayormente asociadas con el rendimiento en hueso. En los enteros, el acabado de grasa y la longitud de la canal explicaron la mayor variación en RCD. El recorte de grasa se asoció más con acabado de grasa, y el rendimiento en hueso se asoció con la conformación. Las ecuaciones obtenidas lograron explicar más del 50% de la variación del RCD. Las ecuaciones para recorte de grasa y rendimiento en hueso tuvieron mayor fuerza predictiva.

“…Heavier carcasses are usually fatter and Koch & Dikeman (1977) noted that the changing proportion of wholesale cuts in carcasses is more likely to result from differences in relative amount and distribution of fat than from differences in muscle and bone. Abraham et al ( 1976) stated that "there is probably unanimous agreement among research workers that some measure of external fatness is the most important single factor affecting the yield of retail cuts from beef carcasses". Butterfield (1965) noted that the amount of fat is of major importance in its effect on the yield of trimmed saleable meat and Table 7 Percentage values of primal cuts and manufacturing meat in Japanese export carcases.…”

Taurindicus cattle from Queensland supply 40% of the Japanese grass-fed, chilled beef trade and much of Queensland's domestic market. Regression analyses of commercially important carcass characteristics and anatomical components on side weight and rump Ps fat thickness were used to assess the economic value of 24 Hereford (H), 23 Brahman (B), and 22 Brahman × Hereford (BH) steers fed on pasture or lucerne hay for the Australian and Japanese markets. For the Australian domestic trade, when compared at 5 mm fat thickness, B and BH had a significantly greater percentage of total primal cuts than H, and B had a significantly greater percentage of saleable beef yield than H. BH carcasses had a significantly greater weight of saleable beef yield, side muscle, and were more valuable ($A318) than B ($A280) and H ($A267). When estimates were made at 100 kg side weight, B had a significantly greater weight A98063 Received 4 December 1998; accepted 8 June 1999of saleable beef yield and side muscle than H. BH had a significantly greater economic value ($A268) than H ($A260) and B ($A231). In the heavier carcasses suitable for Japan, at 14 mm fat thickness, BH had a significantly greater percentage of total primal cuts and saleable beef yield than H and B. BH ($A441) and B ($A436) were more valuable than H ($A383). At 165 kg side weight, BH were significantly heavier than the other two genotypes (P < 0.01) in saleable beef yield and side muscle, significantly lighter in side fat (P < 0.01) and significantly more valuable ($A448) than H ($A434) and B ($A395). Taurindicus steers were more profitable for both markets than H or B steers, whether compared at fat thicknesses or side weights.
