“…Diet differences in ADG between Simmental are supported by findings with Charolais and Chianina crossbreds (Prior et al 1977) fed 2.91 or 3.06 Mcal kg -1 ME diets, but are contrary to similar ADGs in large frame steers fed 3.05 or 2.88 Mcal kg -1 ME diets . Hereford consumed more (P = 0.002) DM (g per BW 0.075 basis) than Simmental in the growing phase.…”

“…Ration formulation for commercial beef cattle production will be influenced by the specific breed type being fed. Breed differences in the ability to fatten will result in large breed differences in days to market when cattle are fed to a common compositional endpoint (Prior et al 1977;Vanderwert et al 1985). However, scientific studies often use common nutritional regimens across breeds to prevent confounding.…”

“…The effect of dietary energy content on beef quality has been evaluated with several studies in the past (Arthaud et al 1977;Prior et al 1977;Dikeman et al 1986).

This latter study fed the large type cattle such that their finish exceeded the maximum requirement for the current Canadian yield grade 1 finish while palatability attributes were not directly compared between "small" and "large" cattle types.…”

. 1998. Effects of breed and dietary energy content within breed on growth performance, carcass and chemical composition and beef quality in Hereford and Simmental steers. Can. J. Anim. Sci. 78: 533-541. Forty-eight Hereford and 60 Simmental steers were used to evaluate breed differences as affected by dietary energy content on growth performance, carcass and chemical composition, and beef quality. Diets were based on corn silage, alfalfa haylage, whole corn, and SBM and were formulated to provide 2.52 to 2.81 Mcal kg -1 ME and 11.7 to 12.6% protein in the growing phase and 2.69 to 2.86 Mcal kg -1 ME and 9.7 to 10.4% protein in the finishing phase. Low-and high-energy diets were formulated for each breed with the high-energy diet for Hereford serving as the low-energy diet for Simmental. Steers were slaughtered after attaining 8 to 10 mm backfat determined by ultrasound. Higher energy diets increased (P < 0.09) average daily gain (ADG) and feed efficiency within both breeds. Hereford gained more rapidly (P = 0.074) and were more (P = 0.001) efficient in converting feed to gain than Simmental. High-energy diets decreased (P = 0.001) days on feed for both breeds and increased (P = 0.001) carcass weights for Simmental. Otherwise, carcass and chemical composition were generally unaffected by dietary energy content. Simmental were heavier (P = 0.001) and leaner (P = 0.001) than Hereford while marbling classification and intramuscular fat content were similar (P > 0.10) between breeds. While shear force decreased (P = 0.043) feeding the low-energy diet to Simmental, other shear and palatability attributes were unaffected by dietary energy content or breed. Altering dietary energy content for Hereford and Simmental influenced growth performance without affecting carcass and chemical composition and beef quality. Simmental ont été utilisés pour évaluer les différences raciales quant à l'influence du contenu énergétique de l'aliment sur les performances de croissance, sur la composition de carcasse et la composition chimique et sur la qualité de la viande. Les aliments étaient faits d'ensilage de maïs, d'ensilage de luzerne mi-fané, de maïs-grain entier et de tourteau de soja, formulés de façon à fournir de 2,52 à 2,81 Mcal kg -1 de EM et de 11,7 à 12,6 % de protéines dans la phase de croissance et de 2,69 à 2,86 Mcal kg -1 EM et de 9,7 à 10,4 % de protéine dans la phase de finition. Chaque race était exposée à un régime à haute et un à basse teneur énergétique, le régime à haute teneur utilisé pour les Hereford servant de régime à basse teneur pour les Simmental. Les bouvillons étaient abattus lorsque l'épaisseur du gras de couverture, mesurée aux ultrasons, était de 8 à 10 mm. Dans chaque race, les aliments à fort contenu énergétique donnaient lieu à un accroissement (P < 0,09) du GMQ et de l'efficacité alimentaire. Les Hereford grandissaient plus rapidement (P = 0,74) et valorisaient mieux (P = 0,01) leurs aliments que les Simmental. En outre, la durée de l'engraissement était plus courte (P = 0,001) chez les deux rac...

This research aimed to investigate the effects of dietary energy concentration (combined net energy, Nemf) on growth performance and meat quality of yaks raised by barn feeding. In all, 30 male yaks (3‐year old and 114.57 ± 21.56 kg of body weight) were allocated to one of three isonitrogenous dietary treatments that had different Nemf concentrations (low 3.72 MJ/kg, middle 4.52 MJ/kg and high 5.32 MJ/kg, respectively). The yaks were fed for 120 days. The results showed that the final weight, average daily gain, dressing percentage, backfat thickness and loin muscle area were significantly improved (p < .05) with the increase in dietary energy concentration. However, an opposite trend of feed:gain ratio, cooking loss, driage, shear force and moisture content was found. A significant improvement (p < .05) of intramuscular fat content was observed in the high‐energy group. Additionally, the proportion of polyunsaturated fatty acid was increased (p < .05) at the expense of the saturated fatty acids. The mRNA expressions of lipogenic genes fatty acid synthase, acetyl‐CoA carboxylase, sterol regulatory element‐binding protein 1, stearoyl‐CoA desaturase, peroxisome proliferator‐activated receptor γ, lipoprotein lipase and heart fatty acid‐binding proteins increased (p < .05) in a dose‐dependent manner. However, the mRNA expressions of lipolytic genes carnitine palmitoyltransferase‐1 and hormone‐sensitive lipase correspondingly decreased (p < .05) with increased dietary energy level. In summary, the growth performance, meat production and meat quality improvement of finishing yaks can be achieved by increasing the dietary energy concentration. The intramuscular fat accumulation of yaks was achieved through up‐regulation of intramuscular lipogenic gene expression as well as fatty acid transport gene expression and down‐regulation of lipolytic gene expression by promoting dietary energy concentration.
