“…However, the intake of CP and NFC was lower with the palm kernel cake supplement ( P < 0.05), because of the high EE (11.18%) and low CP (13.12%) compared with soybean, sunflower and peanut cakes. Therefore, milk production (kg/day) may have been a direct reflection of DMI, one of the determinants of the performance of the animals and the starting point for the inflow of nutrients, especially the energy and protein required to meet the nutritional requirements for maintenance and production (Bezerra et al )…”

This study compared the productive and nutritional parameters of milk from crossbred lactating cows managed on Panicum maximum Jacq. cv. Tanzania and with a diet supplemented with different pressed oilseed cakes. The supplements used were as follows: peanut cake, sunflower cake and palm kernel cake for replacement of soybean meal. Sixteen cows with an average weight of 544 ± 57 kg and producing 8 ± 1.4 L of milk per day were used in this study. The animals were randomly assigned to the treatments according to a Latin square design repeated over time, with four treatments, 16 animals and four experimental periods. Supplementation of the diet with peanut cake, sunflower cake and palm kernel cake compared with soybean meal in the diet of cows did not affect the average daily production or composition of the milk. The palm kernel cake promoted an increase in lauric fatty acids (C ) and palmitoleic acids (C ) (5.02 and 1.65%, respectively) compared with peanut cake and sunflower cake (4.13 and 4.01%, respectively). The levels of oleic fatty acids (C ) were higher for the sunflower cake and palm kernel cake supplements (26.01 and 25.01%, respectively) compared with peanut cake (23.11%). The replacement of soybean meal with sunflower cake and palm kernel cake improved the nutritional quality of the milk, with lower concentrations of saturated fatty acids and higher concentrations of unsaturated fatty acids, without compromising the production or nutritional composition of the milk. © 2015 Japanese Society of Animal Science.

“…The farmer can, for example, opt to obtain production rates and carcasses with different characteristics depending on the sex of the animals [5–7]. In tropical semi-arid regions, animals can be submitted naturally to periods of feed restriction (FR) due to feed supply variations or due to feed management planning, which is commonly used to save resources and reduce costs [8, 9]. Under these conditions, it may be assumed that in addition to lower performance, meat products may have different chemical and physical characteristics if the animals are sold [10, 11].…”

BackgroundAn experiment was conducted to evaluate the effects of feed restriction (FR) and sex on the quantitative and qualitative carcass traits of Morada Nova lambs. Thirty-five animals with an initial body weight of 14.5 ± 0.89 kg and age of 120 d were used in a completely randomized study with a 3 × 3 factorial scheme consisting of three sexes (11 entire males, 12 castrated males and 12 females) and three levels of feeding (ad libitum – AL and 30% and 60% FR).ResultsEntire males presented greater hot and cold carcass weights (P < 0.05), followed by castrated males and females. However, the hot carcass yield was higher for females and castrated males than for entire males. Luminosity values were influenced (P < 0.05) by sex, with entire males presenting higher values than castrated males and females. Females showed higher (P < 0.05) concentrations of linoleic acid and arachidonic acid in the meat of the longissimus thoracis muscle. The meat of animals submitted to AL intake and 30% FR showed similar (P > 0.05) concentrations, and the concentrations of palmitic acid, palmitoleic acid, stearic acid, oleic acid and conjugated linoleic acid were higher (P < 0.05) than those of animals with 60% FR. The meat of females had a higher ω6/ω3 ratio and lower h/H ratio, and females had greater levels of feeding. The meat of animals on the 60% FR diet had a greater ω6/ω3 ratio, lower h/H ratio and lower concentration of desirable fatty acids in addition to a greater atherogenicity index (AI) and thrombogenicity index (TI).ConclusionLambs of different sexes had carcasses with different quantitative traits without total influence on the chemical and physical meat characteristics. The lipid profile of the meat was less favorable to consumer health when the animals were female or submitted to 60% feed restriction.

“…Cuando se compara la eficiencia en el crecimiento animal como efecto de la suplementación, los animales con raciones más concentradas en nutrientes mejoran su desempeño (Avilés et al, 2015). Estas diferencias en la suplementación implican que, las dietas más enriquecidas en nutrientes mejoren la ganancia diaria de peso, porque se suple más energía metabolizable y proteína que un sistema de alimentación a base de forraje (Bezerra et al, 2013;Pinto et al, 2015;Pouzo et al, 2015).…”

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.
