“…Other authors have clearly demonstrated the effect of maturity of animals (different ages or categories) on the percentage of primary cuts of the carcass, especially the pistolcut, which is higher in carcasses of young animals, as demonstrated by Restle et al (2000) and Restle et al (2001), evaluating Charolais heifers and cull cows, and Ferreira et al (2009), in a study with crossbred Charolais × Nellore steers. In a comparison between males and females of similar age, Vaz et al (2010b) and Santos et al (2008) found similarities between the percentages of the forequarter and pistolcut, supporting the statements of Berg & Butterfield (1976), that differences in the development of front and rear are not evident when comparing castrated females with males of the same age.…”

“…But the forequarter of the bulls was higher (50.1 kg) than for cull cows (46.3 kg), although these categories were statistically similar (P>0.05) for pistolcut and sidecut weights. Assessing crossbred Charolais × Nellore cull cows and steers, Ferreira et al (2009) reported a higher weight of the forequarter and pistolcut for the cows, a fact related to the higher cold carcass weight (277.1 vs. 228.1 kg). Other studies show a positive relationship between the weight of commercial cuts and slaughter weight or carcass weight, both in steers Costa et al 2002;Arboitte et al, 2004) and cull cows (Kuss et al, 2005).…”

“…Evaluating the percentages of the commercial cuts of the carcass, Restle et al (2000) and Restle et al (2001) reported superiority of younger females for the percentage of saw cut in relation to the more mature ones, while Ferreira et al (2009) observed advantage of steers in relation to cull cows. and Cattelam et al (2009) observed greater percentage of fat and lower percentage of muscle in cull cows than in steers carcasses, while Vaz et al (2010a) reported similarity in muscle: bone and muscle+fat:bone relation by comparing young steers with heifers.…”

-The objective of the experiment was to study the carcass physical composition and meat qualitative characteristics of different categories of Charolais cattle, feedlot finished. Nine steers (ST), ten heifers (HE), with average age of 20 months, and ten cull cows (CO) with average age of 87 months, taken from the same herd, were used. Diet contained 13% of crude protein for ST and HE and 10% for CO, with roughage:concentrate relation of 50:50, on a dry matter basis.The animals of the three categories were slaughtered with similar degree of finishing, with average subcutaneous fat thickness of 3.8 mm. HE showed carcasses with greater pistolcut percentage (52.8%) than ST (51.0%) and CO (51.4%). The carcass physical composition was similar among the categories evaluated, with 66.5; 67.0 and 67.3% of muscle, 19.1; 18.5 and 18.7% of fat, and 14.9; 15.0; and 14.6% of bone, respectively, for ST, HE and CO. The marbling score was lower for HE (4.6 points) than ST (7.1 points) and CO (6.5 points). However, when this characteristic was adjusted for 100 kg of cold carcass, the means were similar among the categories. CO showed higher cooking losses (27.8%) than ST (21.4%) and HE (23.5%). Meat color, texture, tenderness, shear force, palatability and juiciness were similar among the categories. Charolais cows have the potential for the production of carcass and meat with quality similar to steers and heifers.

“…As commented by Ferreira et al (2009), for cows to achieve similar yield to the steer greater fat deposition is necessary in the cow than in the steer carcass. The effect of fat disposition on cow carcass yield was evident in the study by Kuss et al (2005), who observed that with increased backfat thickness from 4.72 to 7.54 mm, the hot carcass yield increased significantly from 51.9 to 54.93 kg hot carcass/100kg live weight.…”

The objective of the present study was to assess the carcass and meat characteristics of cows and castrated crossbred steer from dairy breeds fed in a feedlot with different levels of crude glycerin in the diet. Twenty-four animals were used, 12 cows with 467 ± 15 kg initial bodyweight and 12 steer 347 ± 17 kg initial bodyweight. A complete randomized design in a 4 x 2 factorial arrangement (four crude glycerin levels and two animal categories) was used. The crude glycerin levels were 0, 60, 120 and 240 g/kg in dry matter diet, formulated with 800 g concentrate/kg dry matter. Including crude glycerin in the diet did not alter carcass weight and yield, backfat thickness and meat qualitative characteristics. Cows presented heavier hot carcass (279.4 versus 231.8 kg) with greater backfat thickness (3.8 versus 5.2 mm) than steer. Crude glycerin in quantities from 0 and 120 g/kg dry matter diet resulted in less muscle and greater fat participation in the cow carcass compared to the steer carcass. The cow meat was darker in coloring and had a higher degree of marbling than the steer. There was no difference for tenderness or total liquid losses during meat thawing and cooking between cows and steer. Crude glycerin can be added up to 240 g/kg diet dry matter for cows and steer from dairy breeds, because it does not decrease the quality of the carcass or the meat produced.

Foram utilizados 24 animais, sendo 12 vacas de descarte com peso corporal inicial de 467 ± 15 kg e 12 novilhos com peso corporal inicial de 347 ± 17 kg. O delineamento experimental foi o inteiramente casualizado, com os tratamentos em arranjo fatorial 4x2 (quatro níveis de glicerina bruta e duas categorias animal). Os níveis de glicerina testados foram de 0, 60, 120 e 240 g/kg de matéria seca de dietas formuladas com 800 g de concentrado/kg de matéria seca. A inclusão de glicerina bruta na dieta não alterou o peso e o rendimento de carcaça, a espessura de gordura subcutânea e as características qualitativas da carne. Vacas apresentaram carcaças quentes mais pesadas (279,4 vs. 231,8 kg) maior espessura de gordura subcutânea (13,8 vs. 5,2 mm) que novilhos. A glicerina em quantidades de 0 e 120 g/kg de matéria seca da dieta proporcionou menor participação de músculos e maior de gordura na carcaça de vacas em relação à carcaça de novilhos. A carne das vacas apresentou coloração mais escura e maior grau de marmoreio que novilhos. Não houve diferença para a maciez e nas perdas totais de líquidos durante descongelamento e cocção da carne entre vacas e novilhos. A glicerina pode ser adicionada em até 240 g/kg de matéria seca da dieta de vacas de descarte e novilhos castrados mestiços de raças de aptidão leiteira, pois não diminui a qualidade da carcaça e da car...

“…As semelhanças nas características quantitativas da carcaça podem ser atribuídas ao peso de abate semelhante dos animais, já que estas características são altamente relacionadas ao peso de abate (Arboitte et al, 2004). Ferreira et al (2009), alimentando os animais duas, três ou quatro vezes, não observaram diferença nas características da carcaça de vacas e novilhos confinados.…”

RESUMOObjetivou-se avaliar a influência de diferentes freqüências do fornecimento do volumoso e concentrado sobre as características da carcaça nas categorias vaca e novilha, terminadas em confinamento. Foram utilizadas 16 novilhas e 16 vacas, com idade média de 20 e 66 meses e peso médio inicial de 338 e 432 kg, respectivamente, provenientes de gerações avançadas do cruzamento rotativo contínuo entre as raças Charolês e Nelore. Os tratamentos representados pelas freqüências do fornecimento do volumoso (V) e do concentrado (C), foram: 2 V/C (V e C duas vezes ao dia); 1 V/C (V e C uma vez ao dia); 1 V/ 2 C (V uma vez e o C duas vezes ao dia); 1 V/3 C (V uma vez e o C três vezes ao dia). Cada fornecimento alimentar foi ofertado às categorias vaca e novilha. A dieta fornecida foi composta de 60 % de silagem de milho e 40 % de concentrado com base na matéria seca. O abate foi realizado em frigorífico comercial, seguindo as normas do estabelecimento. O delineamento experimental utilizado foi inteiramente casualizado em arranjo fatorial 4 x 2 (fornecimento x categoria). Os dados foram submetidos à análise de variância e as médias comparadas pelo teste t. Não houve interação significativa entre freqüência de fornecimento e categoria animal. A freqüência de fornecimento não promoveu alterações nas características da carcaça avaliadas (p>0,05). As vacas apresentaram maior peso de abate e de carcaça quente e fria em relação às novilhas (525,5; 291,0; 281,7 kg vs. 424,7; 236,1; 227,5 kg, respectivamente). Entretanto, as carcaças das novilhas apresentaram maior porcentagem de traseiro do que as vacas. SUMMARYThe influence of different frequencies of supply of roughage and supplement on carcass characteristics of feedlot cows and heifers was studied. Sixteen heifers and sixteen cows, with average age of 20 and 66 months and initial weight of 338 and 432 kg, respectively, from advanced generations of Charolais and Nellore continuous rotational crossbreeding were used. The treatments, representing the frequencies of the supply of roughage (V) and concentrate (C), were: 2 V/C (V and C twice a day); 1 V/C (V and C once a day); 1 V/2 C (V once a day and C twice a day); 1 V/3 C (V once a day and C three times a day). Each treatment was offered to cows and heifers. The supplied diet was composed by 60 % of corn silage and 40 % of concentrate, on dry matter basis. The slaughter was carried out in commercial refrigerated slaugher house, following
