    Abstract: The carcass characteristics from young bulls or steers from different breed compositions of Charolais x Nellore were the objective of this study. Seventy beef males from three breeding systems: straightbreds (Charolais (Ch) and Nellore (Ne)), G1 crossbreds (1/2 Ch 1/2 Ne and 1/2 Ne 1/2 Ch) and G2 crossbreds (3/4 Ch 1/4 Ne and 3/4 Ne 1/4 Ch) were used. Thirty-five males were castrated (steers) at seven months and 35 were kept entire (young bulls). The animals were confined from 20 month to the slaughter time, at 24 months of age. No interaction was observed between breed composition and sexual condition, for any of the studied variables. The young bulls showed higher slaughter and carcass weight, forequarter and muscle percentage and conformation, while the steers showed higher fat thickness, fat, pistol cut and sidecut percentage. Among breeding systems, crossbreds animals showed higher values for slaughter weight, carcass weight, dressing percentage, carcass length, leg length, cushion thickness and arm perimeter, and the heterosis values were 16.36, 20.10, 3.08, 3.71, 4.09, 6.04 and 4.56% in G1, and, in G2, of 10.03, 11.48, 1.09, 3.02, 2.49, 6.08 and 4.56%, respectively. Comparing the Ch and Ne breeds, the first showed higher slaughter and carcass weight, while the dressing percentage and carcass fat thickness were better in Ne animals. There was no difference among 1/2 Ch 1/2 Ne and 1/2 Ne 1/2 Ch animals for any one of the studied traits.

    Abstract: The objective of the experiment was to evaluate the weight, the feed intake, the average weight gain and feed: gain ratio of culled cows, straightbreds (Charolais-C and Nellore-N) and crossbreds (½ CN and ½ NC) during the finishing phase as well as measuring the resulting heterosis. The cows were confined during 80 days, all of them fed with a 10% crude protein diet and forage: concentrate ratio of 65:35. The F1 cows were heavier at the beginning (402 vs. 362 kg) and at the end of the feedlot confinement (524 vs. 475 kg), being the heterosis of 11.05 and 10.31%, respectively. The average weight gain of the F1 cows (1.557 kg) was similar to the straightbreds (1.424 kg). The dry matter intake (DMI) in kg/animal.day (DMID) was 11.26% higher for F1 than for straightbred cows. However, when DMI was expressed in relation to the metabolic weight (DMIM) and per 100 kg of LW (DMIP), the difference decreased to 3,25 and 3,57%, respectively, and became non significant. The C cows were heavier and showed higher average daily gain (1.553 vs. 1.424 kg) than he N. The F1 ½ CN cows were heavier and more efficient in converting feed in weight gain, than the ½ NC.

    Abstract: The objective of this work was to evaluate the performance of beef calves, from birth to weaning, produced by Charolais (C), Nellore (N), CN and NC crossbred cows, kept on native pasture, supplemented with rice bran and weaned at 42 or 63 days postpartum, or non supplemented and weaned at 63 days. Cow age ranged from 3 to 12 years, being classified as: first calf, young, adult and old cows. Calves weaned at 63 days of age, whose cows were supplemented showed higher average daily weight gain (ADG) during lactation (561 vs. 457 g), were heavier at weaning (67 vs. 59.9 kg) and at 84 days (76 vs. 69,2 kg) in relation to those whose cows were not supplemented, and did not differ in weight from the last ones at 5, 7 and 12 months. Calves weaned at 42 days showed lower ADG during the first 21 days after weaning (360 vs. 482g) and were lighter at 12 months (174.4 vs. 189.4 kg) in relation to those weaned at 63 days. Crossbred calves produced by CN and NC crossbred cows were heavier at weaning then the straightbreds, not differing from the C calves at 12 months. Nellore calves were similar in weight to the C calves at weaning, but were lighter and displayed lower body condition score than the C at 5, 7 and 12 months. Calves produced by first calving cows were lighter and displayed lower body condition score than the other calves, however, not differing from the last ones at 9 and 12 months. Supplementation of cows is not justified when calf weight after 5 months is considered. Weaning calves at 42 days is not recommended because it results in lower weight at 12 months.

    Abstract: Quantitative carcass traits of cull cows from two breeding systems, straightbreds (Charolais - C and Nellore - N) and crossbreds F1 ¹/2 CN and ¹/2 NC, were evaluated. The cows were feedlot finished and fed with a 10% crude protein diet with 65% roughage, sorghum silage, and 35% concentrate. Objective and subjective measurements were taken from the cold carcasses. Charolais females showed higher slaughter weight (522.6 vs 462 kg) and cold carcass weight (255.8 vs 237.5 kg), conformation score (10.7 vs 7.76 points) and Longissimus dorsi area (64.08 vs 55.92 cm²). Whereas the Nellore were superior in dressing percentage (51.31 vs 48.93%) and subcutaneous fat thickness (8.22 vs 4.59 mm). Crossbred F1 females were superior to the straightbreds for slaughter weight (525.7 vs 492.3 kg), cold carcass weight (269.8 vs 246.6 kg), dressing percentage (51.3 vs 51.12%), conformation score (9.84 vs 9.24 points) and subcutaneous fat thickness (7.77 vs 6.40 mm), being the heterosis values 6.78, 9.41, 2.35, 6.49, and 21.40%, respectively. Crossing Charolais and Nellore resulted in cull cows with carcasses with high weight, good conformation and high degree of subcutaneous fat.

    Abstract: The objective of this experiment was to evaluate the physical carcass composition, meat quality and cholesterol content in the Longissimus dorsi muscle of 5/8 Nellore - 3/8 Charolais steers feedlot finished to reach slaughter weight (SW) of 425, 467 and 510 kg. At the beginning of feedlot, average age, weight and body condition were, respectively, 660 days, 361 kg and 2.9 points. The diet offered, with roughage:concentrate ratio of 60:40, contained 10.25% of crude protein, 72.18% of total digestible nutrients and 3.18 Mcal of digestible energy/kg of DM. The muscle ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22092s1.gif" WIDTH=11 HEIGHT=15 〉 or = 15.548+0.316SW), fat ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22092s1.gif" WIDTH=11 HEIGHT=15 〉 or = -75.971+0.290SW) and internal fat ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22092s1.gif" WIDTH=11 HEIGHT=15 〉 or = -61.955+0.178SW) of the carcass quantity increased linearly as SW increased. However, the muscle percentage declined ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22092s1.gif" WIDTH=11 HEIGHT=15 〉 or = 90.294-0.059PA), the fat percentage increased ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22092s1.gif" WIDTH=11 HEIGHT=15 〉 or = -5.320+0.060PA) and bone percentage was not alterated (14.93%) by SW. The muscle:bone (4.28) and muscle+fat:bone ratio (5.80) was not influenced by SW. The meat color (4.28 points) and texture (3.28 points) were not influenced, however, marbling increased linearly (Ÿ = -8.403+0.035SW) as the SW increased. Slaughter weight did not influence meat thawing (11.13%) and cooking losses (23.94%). The tenderness was classified between "tender and very tender" (6.77 points), palatability between "flavorful and very flavorful " (6.77 points) and juiciness between "juicy and very juicy" (6.88 points), were not influenced by SW. The Longissimus dorsi muscle showed 1.63% of ether extract and 53.12 mg of cholesterol/100 g of muscle, remaining constant with SW increase. Positive correlation of ether extract percentage in the Longissimus dorsi muscle with subcutaneous fat thickness (0.42), with marbling score (0.46) and with cholesterol content (0.60) was observed.

    Abstract: The carcass quantitative characteristics of 5/8 Nellore-3/8 Charolais steers feedlot finished to reach slaughter weight (SW) of 425, 467 and 510 kg, were studied. At the beginning of the feedlot the average age, weight and body condition were, respectively, 660 days, 361 kg and 2.9 points. The diet offered, with 60:40 roughage:concentrate relation, dry matter basis (DM), contained 10.25% crude protein and 72.18% of total digestible nutrients. The roughage was corn silage with 46.5% of grain in the DM. Cold carcass dressing percentage showed linear relation with SW ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22093s1.gif" WIDTH=11 HEIGHT=15 〉 or = 37.618 + .011Pi (initial weight) + .028SW). However, when dressing percentage was expressed in relation to empty body weight (EB), it was not influenced by SW. Subcutaneous fat thickness expressed per cold carcass ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22093s1.gif" WIDTH=11 HEIGHT=15 〉 or = -15.499 - .001Pi + .047SW), per 100 kg of cold carcass weight ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22093s1.gif" WIDTH=11 HEIGHT=15 〉 or = -1.724 - .006Pi + .013SW) and per 100 kg of EB ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22093s1.gif" WIDTH=11 HEIGHT=15 〉 or = -1.124 - .003Pi + .008SW) increased as SW increased. Longissimus dorsi area increased linearly with SW ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22093s1.gif" WIDTH=11 HEIGHT=15 〉 or = -33.472 + .120Pi + .120SW), however, when expressed per 100 kg of cold carcass weight it declined ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22093s1.gif" WIDTH=11 HEIGHT=15 〉 or = 45.173 - .023Pi - .028SW), and when expressed per 100 kg of EB, it did not show relationship with SW. The percentage of sawcut declined ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22093s1.gif" WIDTH=11 HEIGHT=15 〉 or = 63.007 - .001Pi - .026SW) while the side cut increased ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22093s1.gif" WIDTH=11 HEIGHT=15 〉 or = -3.054 + .005Pi + .030SW), as SW increased. Slaughter weight influenced positively cushion thickness ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22093s1.gif" WIDTH=11 HEIGHT=15 〉 or = 6.223 + .014Pi + .031SW), leg length ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22093s1.gif" WIDTH=11 HEIGHT=15 〉 or = 28.326 + .061Pi + .05SW) and arm perimeter ( 〈 IMG SRC="/img/revistas/rbz/v33n4/22093s1.gif" WIDTH=11 HEIGHT=15 〉 or = 9.173+ .053Pi + .017SW). Carcass conformation was not alterated by SW.
