“…Table 2 shows that all primal cuts were heavier for crossbred females than purebred ones (P<0.05), which is related to the highest slaughter and carcass weights reached by these animals. Oliveira et al (2009) and Goes et al (2012) ascertained that outstanding weights for primal cuts only occur when slaughter weights are not equal, as observed here.…”

This research aimed to compare carcasses of purebred and crossbred Nellore females reared uniquely on pasture (Brachiaria decumbens and Brachiaria brizantha cv. Marandu). Breeds assessed consisted of purebred Nellore (16) and Nellore x Santa Gertrudis crossbred (16), being 32 ± 1.5 months old. All animals were slaughtered as they reached 450 kg. Crossbred females showed higher slaughter, hot and cold carcass weights and longer lengths (P < 0.05). Conversely, purebred animals attained greater carcass yields (P < 0.05). Nonetheless, crossbred females had higher primal cut weights and plate/ flank percentage (P < 0.05). Also, non-carcass components as kidneys, liver, kidney-pelvic-heart fat showed higher weights for crossbred females (P < 0.05). Thus, regarding beef cattle reared and finished exclusively on grazing areas, crossbred females (Nellore x Santa Gertrudis) may be the most profitable ones for cattle raisers, since they produce heavier slaughtering carcasses. Notwithstanding, they might be interesting for meat industry, for yielding more in prime cuts than purebreds, even if raised at the same conditions and slaughtered at same age. Key words: Bovines. Brachiaria. Commercial cuts. Breeds. Slaughter. ResumoObjetivou-se comparar as características da carcaça de fêmeas bovinas contemporâneas de diferentes grupos genéticos criadas e terminadas exclusivamente em pastagem (Brachiaria decumbens e Brachiaria brizantha cv. Marandu). Foram utilizadas 16 da raça Nelore e 16 Nelore x Santa Gertrudis, com idade média de 32 ± 1,5 meses. Os animais foram abatidos no mesmo dia quando as fêmeas Nelore atingiram o peso aproximado de 450 kg. As fêmeas cruzadas apresentaram maiores (P < 0,05) peso de abate, de carcaça quente e resfriada e comprimento da carcaça, já as Nelore apresentaram o melhor rendimento de carcaça (P < 0,05). Os pesos de todos os cortes primários, o rendimento da ponta de agulha e os pesos dos rins, fígado, gordura perirenal-pélvica-inguinal foram maiores (P < 0,05) para as fêmeas cruzadas. Quando se utiliza sistemas de produção de bovinos criados e terminados em pastagem, o uso de fêmeas cruzadas Nelore x Santa Gertrudis é mais vantajoso para o produtor, pois apresentam carcaças mais pesadas, e para a indústria de carne, pelo maior rendimento de cortes nobres, do que fêmeas Nelore criadas nas mesmas condições e abatidas com a mesma idade.

“…They suggest that above this value, the meat should be classified as dark, firm and dry, and the rejection of this kind of meat by consumers is higher. Thus, the average value (5.76) obtained in this study was within the ideal pH range because Brazilian slaughterhouses export only beef with pH below 5.8, which is directly assessed in the longissimus dorsi muscle 24 h postmortem (Oliveira et al, 2009).…”

-The objective of this study was to evaluate the effect of different lipid sources on nutrient intake, performance, development and carcass characteristics of heifers raised in confinement. Twenty-one crossbreed heifers (Nellore × Santa Gertrudis × Braunvieh) received 600 g/kg forage composed of corn silage and 400 g/kg concentrate with a 58.0 g/kg fat content in the total diet. The following lipid sources were used: soybeans, protected fat (Megalac-E ® ) and soybean oil. The experimental design was completely randomized, with three treatments and seven replicates, and the means were compared by the Tukey test at 5%. The protected fat diet resulted in a greater intake of dry matter (8.80 kg/d) when compared with the other diets. The animals that were fed the protected fat diet had a higher average daily weight gain and slaughter weight.Feed conversion and protein efficiency rate were not influenced by lipid sources. Carcass yield was not influenced by the different diets.

“…Despite this, it is widely known that cattle breeds specifically bred for milk production have lower muscularity than beef cattle, due to the different aims and selection pressures associated with the evolution of these biotypes (Albertí et al, 2008). However, dual-purpose dairy crossbred bulls have muscularity similar to that of specialized cattle breeds, especially in relation to zebu cattle, which have lower muscularity than European breeds (Oliveira et al, 2009;Nogalski, 2013;Silva et al, 2015). The results of the present study highlight the potential of dualpurpose dairy bulls for meat production and income supplementation of dairy farms.…”

-The objective of this work was to evaluate the performance of young Nellore bulls and of young dual-purpose dairy bulls fed proportions of 'Mulato II' grass silage (400 and 100 g kg -1), in diets with high levels of concentrate, as well as to evaluate the cost of this feed. Sixteen young Nellore bulls and 16 young dairy crossbred bulls were used, with initial average weight of 380.69±10.45 and 376.94±17.16 kg, respectively, and average initial age of 24 months. A completely randomized experimental design was carried out in a 2x2 factorial arrangement. The highest silage proportion caused a 13% increase in dry matter intake (percentage of body weight) and a 19.7% decrease in dry matter digestibility of the diet, but it did not alter the intake of total digestible nutrients, nor the average daily gain or carcass characteristics. Nutrient intake and digestibility, average daily gain, and carcass characteristics (except conformation) did not change due to the genetic group of animals. Feed conversion was 18.3% better in young dairy bulls. In diets with high levels of concentrate, the proportion of 400 g kg -1 of 'Mulato II' grass silage, in comparison with that of 100 g kg -1, does not affect the productive performance, nor the main carcass characteristics of economic interest of confined young bulls, but reduces feeding costs.
