ABSTRACT El ganado bovino sacrificado en los valles centrales de Oaxaca muestra alta diversidad debido a que procede de diferentes regiones y sistemas de producción (SP). El objetivo del estudio fue caracterizar el ganado bovino sacrificado, y para ello se evaluaron 1,375 canales, determinando raza, edad, procedencia, SP, espesor de grasa dorsal, marmoleo, conformación y peso de la canal caliente (PC). El 95 % de los animales sacrificados provinieron del trópico y de estos, el 75 % fue criado en sistema de pastoreo. Las cruzas predominantes fueron Cebú x Suizo Pardo (37 %) y Cebú x Holstein (16 %) entre los 3 y 4 años de edad. Los toros provenientes del trópico húmedo presentaron el promedio más alto de PC (309.4 kg; P<0.05). Los toros raza cebú y cruzas Cebú x criollo y Cebú x Suizo Pardo obtuvieron los mayores promedios de PC (325.8, 301.6 y 297.8 kg, respectivamente). La mayor proporción de canales con buena conformación fueron obtenidas de toros y toretes provenientes del trópico húmedo (P<0.05) y en los SP pastoreo-complemento y engorda intensiva (78.8 y 85.2 %, respectivamente). Los novillos raza Cebú criados en engorda intensiva y pastoreo-complemento obtuvieron mayores (P<0.05) espesores de grasa (5.1 y 3.5 mm). La raza tiene influencia en la composición de la canal, después de ella, el sistema de producción, la alimentación y la madurez son determinantes en el rendimiento y calidad de la canal.

    ABSTRACT: Summary In this study, carcass performance from data on 371 steers produced in a four-breed diallel crossing design was evaluated. Steers of the Angus, Hereford, Holstein and Brown Swiss breeds and all possible two-breed combinations were slaughtered at an average age of 14 mo. Based on breed effects from the analyses of variance, the dairy (Holstein and Brown Swiss) had heavier slaughter and carcass weights and less external fat than the beef (Angus and Hereford) breeds. The Brown Swiss breed had the largest longissimus muscle area, the highest estimated cutability percentage and the lowest marbling scores and quality grades of the four breeds. The Angus breed had the highest marbling scores and quality grades. The Hereford breed had the lowest estimated kidney fat percentage of the four breeds. The Holstein breed did not differ from the Hereford breed for marbling score and quality grade. Significant average heterosis was found for slaughter weight, carcass weight, longissimus muscle area, estimated kidney fat percentage, marbling score and quality grade. Beef x dairy crosses ex- hibited heterosis for marbling score and quality grade, whereas Angus x Hereford and Holstein  Brown Swiss crosses did not. The beef  dairy crosses were similar to beef steers in ability to marble and quality grade, were intermediate between beef and dairy steers in external fat deposition and were similar to dairy steers in amount of carcass produced.

    ABSTRACT: Carcass and meat traits of 422 steers differing in the ratio of Brahman (B), Sahiwal (S) or Pinzgauer (P) to Hereford (H) and(or) Angus (A) inheritance were studied. Reciprocal backcross and F2 matings produced steers with 0:100 (H x AH and H x HA, A x AH and A x HA, HA x HA and AH x AH; or H x PH, A x PA, P x PH, P x PA, PH x PH, PAx PA), 25:75 (H x BH, A x BA, H x SH, A x SA), 50:50 (BH x BH, BA x BA, SH x SH, SA x SA, SH x BA) and 75:25 (B x BH, B x BA, S x SH, S x SA) Bos indicus to Bos taurus inheritance. Increasing the percentage of Bos indicus inheritance decreased carcass weights in the Brahman crosses (P < .05) and Sahiwal crosses (P < .01). The Hereford- Angus breed cross group possessed the greatest (P < .01) adjusted fat thickness but 12th rib longissimus muscle areas similar to those of Brahman or Sahiwal crosses. In general, marbling decreased (P < .01) as the percentage ofBos indicus breeding increased; however, maturity scores were similar among all breed groups. Bos indicus breed crosses were less (P < .01) tender and were more (P < .05) variable in tenderness than Bos taurus breed crosses. As the percentage of Bos indicus inheritance increased, shear values increased (P < .01) and sensory panel tenderness scores decreased (P < .01). Decreases in tenderness were associated with less desirable (P < .01) sensory panel ease-of-fragmentation scores and, to a lesser extent, sensory panel perception of more abundant connective tissue content of meat samples. Flavor characteristics were similar among all breed groups of cattle.

    ABSTRACT: SUMMARY Two types of cattle (Angus-Hereford cross- breds, small type; and 3/4- or 7/8-Charolais and Chianina Hereford or Chianina Angus cross- breds, large type) were evaluated for their response to different dietary energy densities (2.9, 3.1, or 3.2 Mcal ME/kg dry matter) (low, LE; medium, ME; and high, HE, respectively) and three dietary levels of crude protein (LP = 10, MP = 11.5 or HP = 13% of dry matter) in a 2 x 3 x 3 factorial design. The rations consisted of the following ratios of corn silage to corn plus supplement: LE, 43:67; ME, 25:75; and HE, 11:89. Small type cattle from each treat- ment were slaughtered after 196 and 232 days on experiment (460 -+ 3 and 465 -+ 3 days of age) and large type after 232 and 308 days (464 +- 3 and 566 -+ 3 days of age). Increasing energy intake increased ADG in both types of cattle with HE>LE (P
