“…From the results presented in this paper, it can be also concluded that the strategic use of crossbreds between Local Yellow×Red Sindhi and imported breeds such as LS, DS, and RS will help meet the significantly increased beef meat demand in the DakLak Province. This interpretation is consistent with earlier reports on the positive effects of crossbred cattle on growth and carcass performance [24], and better meat quality [25] in South Asia. However, as noted earlier, it should not obscure the breeding value of the native cattle in Vietnam for quantitative genetic and genomic research aimed at reducing methane emissions and other desirable productive traits.…”

ObjectiveThis study was aimed at evaluating effects of cattle breed resources and alternative mixed-feeding practices on meat productivity and emission intensities from household farming systems (HFS) in Daklak Province, Vietnam.MethodsRecords from Local Yellow×Red Sindhi (Bos indicus; Lai Sind) and 1/2 Limousin, 1/2 Drought Master, and 1/2 Red Angus cattle during the growth (0 to 21 months) and fattening (22 to 25 months) periods were used to better understand variations on meat productivity and enteric methane emissions. Parameters were determined by the ruminant model. Four scenarios were developed: (HFS1) grazing from birth to slaughter on native grasses for approximately 10 h plus 1.5 kg dry matter/d (0.8% live weight [LW]) of a mixture of guinea grass (19%), cassava (43%) powder, cotton (23%) seed, and rice (15%) straw; (HFS2) growth period fed with elephant grass (1% of LW) plus supplementation (1.5% of LW) of rice bran (36%), maize (33%), and cassava (31%) meals; and HFS3 and HFS4 computed elephant grass, but concentrate supplementation reaching 2% and 1% of LW, respectively.ResultsResults show that compared to HFS1, emissions (72.3±0.96 kg CH4/animal/life; least squares means± standard error of the mean) were 15%, 6%, and 23% lower (p<0.01) for the HFS2, HFS3, and HFS4, respectively. The predicted methane efficiencies (CO2eq) per kg of LW at slaughter (4.3±0.15), carcass weight (8.8±0.25 kg) and kg of edible protein (44.1±1.29) were also lower (p<0.05) in the HFS4. In particular, irrespective of the HSF, feed supply and ratio changes had a more positive impact on emission intensities when crossbred 1/2 Red Angus cattle were fed than in their crossbred counterparts.ConclusionModest improvements on feeding practices and integrated modelling frameworks may offer potential trade-offs to respond to climate change in Vietnam.

“…Cattle breeds have a striking effect on meat and fat color, muscle structure and meat physiology (Waritthitham et al, 2010; Xie et al, 2012), as well as their product (milk). Because of genetic background, milk from different cattle breeds holds distinct composition profiles (Poulsen et al, 2012).…”

Cattle breeds have a striking effect on milk, including milk composition and technological characteristics. This study aims to compare milk composition, acidification activity, viscosity, milk dispersion system stability and casein molecular weight among three buffalo breeds in China. The technological characteristics of milk produced by three cattle breeds of river buffalo (Murrah), crossbreed 1st generation (F1), crossbreed multiple generation (FH, H≥3) buffaloes were investigated. Cattle breeds showed evident effect on milk protein, fat and total solids content, but little effect on most of buffalo casein molecular weight. Milk fat, protein content and the viscosity of buffalo milk from river buffalo were lower than those of F1 and FH, so was the buffer capacity. The viscosity was negatively correlated to temperature and concentration. Results of stability coefficient showed that milk dispersion system had the best dynamic stability characteristics under pH 6.6 and 6 times dilution, while zeta potential of Murrah milk was slightly higher than that of hybrid offspring (F1, FH). SDS-PAGE results showed that buffalo αs-casein had a slightly faster mobility than standard αs-casein; while buffalo β-casein showed a slightly slower mobility than standard β-casein. There is no clear differences in molecular weight of αs-, β-, and κ-casein among Murrah, F1 and FH.

“…La tendencia observada a una mayor ganancia diaria en los animales Charolais con respecto a los Brahman, fue descrita y confirmada por varios autores en un sistema de producción convencional, similar al del presente estudio (Tumwasorn et al, 1982;Keane y Allen, 1998). Otros autores han indicado que conforme se incrementa proporcionalmente la composición genotípica de genes Brahman*Charolais, se presentan mejores ganancias de peso vivo (Waritthitham et al, 2010). No hubo diferencias en la ganancia diaria de peso entre los diferentes genotipos, pero otros autores, han reportado mayores ganancias de peso en animales Charolais que en Brahman (Cooke et al, 2004).…”

“…En este estudio, el contenido de grasa perirenal observado en los bovinos Charolais fue mayor que en los Brahman y F 1 Bra*Cha, pero el rendimiento en canal fue mayor en los animales Brahman y F 1 Bra*Cha con respecto a los Charolais, lo que coincide con trabajos similares donde se discute que las diferencias observadas en el rendimiento en canal se pueden explicar por los contenidos de grasa perirrenal, y el grado de desarrollo muscular (Barton y Pleasants, 1997;Muir et al, 2000;Purchas y Morris, 2007). Resultados contrarios a los de este trabajo con respecto a las razas Brahman y Charolais fueron reportados por Waritthitham et al (2010), quienes indicaron que los animales Cebú presentaron menor rendimiento en canal que los europeos. Al analizar el efecto de la suplementación sobre el rendimiento en canal en condiciones de alimentación intensiva y en animales de raza simmental, se encontraron valores menores (57,1%) a los reportados en este trabajo (Sami et al, 2004).…”

“…Las diferencias observadas en los cortes de primera y segunda calidad, estuvieron determinadas por un efecto de los grupos genotípicos que podría explicarse por una heterosis favorecedora para los animales cruzados F 1 Bra*Cha en general. En animales Brahman y Charolais, Waritthitham et al (2010) encontraron que los porcentajes de cortes primarios no cambiaron al aumentar el peso de la canal.…”

Para más información escríbanos a pccmca@ucr.ac.cr ResumenLos sistemas actuales de producción de carne bovina deben ser competitivos y estar orientados hacia la calidad cárnica como concepto de comercialización. El objetivo de este trabajo fue evaluar el componente genético y la suplementación en la fase final de novillos en pastoreo, sobre el crecimiento, composición de la canal y rendimiento cárnico. El periodo de evaluación fue de 126 días durante el año 2013, en la finca "La Vega" ubicada en el Cantón de San Carlos, Alajuela, Costa Rica. Se evaluó: en ganancia diaria de peso, espesor de grasa dorsal, marmoleo, profundidad de músculo, peso en pie, merma de transporte de finca a planta, peso canal caliente, rendimiento pie a canal, conformación muscular, grasa perirenal, diámetro de la pierna, longitud de la canal, área del ojo del lomo, grosor de grasa dorsal, pH y temperatura de la canal (2 y 24 h), merma de peso de canal caliente a canal fría. El componente genotípico de los bovinos incidió sobre las características de canal, así como el tipo de suplementación ofrecida. Los animales cruzados Brahman*Charolais (F1), presentaron mejor desempeño que los Brahman y/o Charolais, en características como profundidad de músculo y rendimiento en cortes cárnicos como lomito, posta de cuarto y punta de solomo. La suplementación ofrecida y el componente genotípico no influyeron en el rendimiento de carne vendible.Palabras clave: ganado de carne, canal animal, carne de res, calidad de la carne. AbstractThe current systems of beef production must be competitive and oriented towards meat quality as a marketing concept. The objective of this investigation was to evaluate on grazing steers the effect of the genotype and nutritional supplementation finishing on growth, carcass composition, and cutability performance. The evaluation period was of 126 days during 2013. The research was conducted at the "La Vega farm" located in San Carlos, Alajuela, Costa Rica. In the investigation an analysis of production characteristics was performed, and the following were determined: daily weight gain, backfat, marbling, muscle depth, packing plant live weight, weight loss from farm to abbatoir, hot carcass weight, dressing %, muscle conformation, round circumference, carcass lenght, rib eye area, backfat, marbling, pH and temperature at 24 h and chill shrinkage.
