“…Slaughter weight was also lower in this treatment, which can be explained by the lower age. Cattle performances in natural grassland and improved-natural grassland were similar to those obtained by Castilhos et al (2007) and Ferreira et al (2011), who studied similar finishing systems. Ultrasound analysis reflected the growth pace obtained with the treatments.…”

-The present study was conducted to assess carcass features, physicochemical and sensory parameters of meat from steers finished on three types of pastures: natural pasture; natural pasture improved, fertilized and oversown with winter species; and annual summer grassland. The experiment was conducted from December 14, 2009 to November 30, 2010, with treatments distributed in a completely randomized design with a different number of replicates. Animals were used as experimental units. Experimental animals were Aberdeen Angus steers with twenty months of initial age and 354±27.4 kg of live weight, on average. The highest average daily gains were obtained for the annual summer grassland.There was no effect of treatments on carcass conformation. The highest carcass yield was obtained on the improved natural pasture. Forequarter yield, side cut yield and longissimus muscle area were similar between the pastures. Moisture and total lipids were not affected by the pasture. Thawing and cooking losses were higher in improved natural pasture and lower in sorghum pasture. Regardless of the treatment, the meat had luminosity ranging from intermediate to dark, high in red, high in yellow, and considered within the normal range for beef. Meat of higher shear force was found in natural pasture, and lower shear force was observed in meat from annual summer grassland. Average live weight daily gain explained 18% of the shear force. Sensory evaluation by duo-trio test showed differences between samples from distinct pastures in flavor.All the studied systems allow for desirable characteristics in carcass and meat.

“…In contrast to our results, Lage et al (2012) found that in a feedlot with two different levels of concentrate in the diet, animals did not show significantly different Longissimus muscle area based on nutritional plan. Moreover, Ferreira et al (2011) and Devincenzi et al (2012) found no significant differences in Longissimus muscle area in animals raised under conditions (A1 vs. A2 environment) similar to this study. We suggest that our results may be influenced by a negative gain imposed by the A2 environment in relation to the ADG in the A1 environment.…”

We analyzed average daily gain from weaning to yearling (ADG), yearling weight (YW), rib eye area, and subcutaneous fat thickness of 91 Angus, Hereford, Caracu, and Nellore cattle, and their crosses. The animals were split into two grazing groups: improved natural grassland (n = 47) and natural grassland (n = 44). The environment was found to influence all traits, and the highest measures of performance were observed in improved natural grassland. The genetic group x environment interaction was verified only for ADG and YW (P < 0.05). We found the best performance trait averages for crossbreeds of Bos taurus and Bos indicus. In addition, we found genetic x environment interaction effects in growing traits and Longissimus muscle area between the evaluated genotype groups. Finally, we found that between the evaluated genotype groups, subcutaneous adipose fat was not influenced by the environment. Key words: Beef cattle. Carcass. Crossbreeding. Environment effect. Genotype. Weaning. ResumoForam analisadas as características de ganho de peso médio diário da desmama ao sobreano (GMD), peso ao sobreano (PS), área do músculo longissimus (AOLUS) e espessura de gordura subcutânea por ultrassom (EGSUS) de 91 animais das raças Angus, Hereford, Caracu e Nelore e seus cruzamentos. Destes, 47 animais foram manejados em pastagem natural melhorada e 44 animais em campo natural do Bioma Pampa. Todas as características foram influenciadas pelo ambiente, sendo que os melhores desempenhos foram observados no ambiente constituído pela pastagem natural melhorada. A interação grupo genético x ambiente foi verificada no GMD e no PS (P < 0,05). As maiores médias das características analisadas pertenceram a produtos do cruzamento entre Bos taurus e Bos indicus. Houve efeito da interação genótipo x ambiente nas características de crescimento e de área do músculo longissimus entre os grupos genéticos avaliados (P < 0,05). A deposição de tecido adiposo subcutâneo não foi influenciada pelo ambiente de criação entre os grupos genéticos estudados. Palavras-chave: Cruzamentos. Efeito ambiental. Genótipo. Pastagem.

“…Conforme relatado por Santos et al (2008), carcaças com melhor conformação são preferidas pelos frigoríficos e açougues, pois estão associadas à maior hipertrofia muscular e maior rendimento de carne na desossa. Ferreira et al (2011) também não encontraram diferenças entre grupos genéticos de novilhos abatidos aos 25 meses em um mesmo tratamento, quanto às características de carcaça, possivelmente, por esses ainda estarem em fase de crescimento. Esses autores catalogaram resultados baixís-simos (subcôncavo) para conformação de carcaça, enquanto que no presente estudo os resultados para o mesmo quesito foram razoáveis (retilíneas), demonstrando superioridade genética e/ou melhores condições de manejo.…”

RESUMO:A pecuária de corte brasileira tem sido marcada por intensas transformações, resultantes da aplicação de técnicas modernas de produção, da utilização dos cruzamentos entre raças, e das exigências do mercado consumidor. O desempenho do período pré-desmama é importante por se tratar do primeiro resultado de produtividade animal e a classificação e tipificação das carcaças possibilitam enquadrá-las em diferentes classes e, assim, direcioná-las a diferentes mercados. O objetivo deste trabalho foi comparar o desempenho pré-desmama e características de carcaças entre dois grupos genéticos: Nelore (NE), e ½ sangue Angus-Nelore (F1), os quais foram abatidos sem castração e suplementados a pasto do nascimento ao abate. Foram tomados, ao acaso, 36 animais sendo 18 machos da raça Nelore (NE) e 18 machos oriundos do cruzamento industrial entre Nelore e Angus, machos (F1), sendo todos submetidos ao mesmo manejo e abatidos sem castração, com idade aproximada de 20 meses. Durante o processo de abate, as carcaças foram classificadas e tipificadas. O grupo F1 foi superior ao grupo NE com diferença significativa referente ao peso ao nascer (p=0,0046), peso ajustado aos 205 dias (p=0,0002), peso ao desmame (p=0,0005), ganho de peso diário entre o nascimento e os 205 dias (p=0,001). Quanto às características de carcaças não houve diferença estatística entre os grupos (p>0,05), sendo que, ambos atingiram a exigência frigorífica para espessura de gordura. Observou-se uma superioridade nos animais F1 quanto ao desempenho pré-desmama, e nota-se a possibilidade de terminar animais inteiros a pasto, com acabamento de carcaça mínimo, desde que bem alimentados. PALAVRAS-CHAVE: Abate. Cruzamento industrial. Desempenho pré-desmama. Machos não castrados. Produtividade. WEIGHT GAIN AND CARCASS CHARACTERISTICS OF NELLORE AND CROSSBREED ANGUS-NELLORECATTLE ON GRAZING SUPPLEMENTATION SCHEME ABSTRACT: The Brazilian beef cattle industry has been marked by dramatic changes resulting from the application of modern production techniques, use of crossbreeding and consumer market requirements. The performance of the pre-weaning period is important because it is the first result of animal productivity, and the evaluation and classification of carcasses enable their categorization into different classes, and thus, their directing to different markets. The objective of this study was to compare the pre-weaning performance and carcass traits between two genetic groups: Nellore (NE) and Angus-Nellore crossbreed (F1), which were slaughtered without castration, receiving grazing supplementation from birth to slaughter. Thirty-six animals were randomly selected, 18 Nelore (NE) and 18 Angus-Nellore crossbreed (F1) animals, all males, submitted to the same management system and slaughtered without castration, with approximate age of 20 months. During the slaughtering process, carcasses were classified and typified. The F1 group was superior to the NE group with significant differences related to birth weight (p = 0.0046), weight adjusted to 205 days (p = 0...
