“…Smaller losses were observed by Silva et al (2008), who gave sugar cane based diets for confined bovines and found average losses of 1.91% during carcass cooling, with fat cover of 2.64 mm, whereas Fernandes et al (2007) and Brondani et al (2006) obtained averages of 2.11 and 2.40 mm for fat thickness on the carcass. However, those results are considered to be low for market requirement for carcass quality.…”

-It was evaluated intake, total apparent digestibility, performance and feeding behavior of bovine fed diets constituted of corn silage, crushed sugar cane given fresh or crushed and given 72 hours after storage, ensilaged sugar cane with or without 1% of calcium oxide and concentrate at the proportion of 1% of the body weight. It was used 35 bovines, distributed in a random block design, with 5 treatments and 6 repetitions. The animals were housed in collective stalls with troughs individualized by electronic gates. The animals fed diet with corn silage presented greater intake of all nutrients and greater total digestibility of dry matter, organic matter, neutral detergent fiber and total digestible nutrients, as well as greater weight gain and subcutaneous fat thickness. Animals fed diet with fresh sugar cane presented greater nutrient intake as well as better dry matter digestibility, ether extract and TDN content and a superior performance in relation to animals fed ensilaged sugar cane diets. Animals fed silage of sugar cane with calcium oxide presented greater digestibility of organic matter, NFC and content of TDN but they did not differ on performance in relation to the use of silage of sugar cane without calcium oxide. Intake and performance of animals did not change with or without storage of sugar cane. It was concluded that animals fed diets with corn silage present performances superior to the ones which are fed sugar cane based diets, and animals fed fresh sugar diet are superior to the animals fed diets with sugar cane silage.Key Words: bovine, carcass, digestibility, electronic gates, feedlot, weight gain Consumo e desempenho de bovinos confinados com dietas à base de cana-de-açúcar fresca ou ensilada e silagem de milho RESUMO -Avaliaram-se o consumo, digestibilidade aparente total, desempenho e comportamento alimentar de bovinos alimentados com dietas constituídas de silagem de milho, cana-de-açúcar triturada e fornecida in natura ou triturada e fornecida após 72 horas de armazenamento, cana-de-açúcar ensilada sem ou com 1% de cal e concentrado fixado em 1% do peso corporal. Utilizaram-se 35 bovinos, distribuídos em delineamento com blocos casualizados, com 5 tratamentos e 6 repetições. Os animais foram alojados em baias coletivas com cochos individualizados por portões eletrônicos. Os animais alimentados com dieta contendo silagem de milho apresentaram maior consumo de todos os nutrientes e digestibilidade total da matéria seca, matéria orgânica, fibra em detergente neutro e teor de nutrientes digestíveis totais, assim como maior ganho de peso e espessura de gordura

RESUMO -O objetivo neste trabalho foi avaliar as características químicas e a composição em ácidos graxos do contrafilé (músculo Longissimus) de tourinhos, novilhos e novilhas da raça Canchim. Os animais foram terminados em confinamento com duas dietas experimentais, uma com silagem de milho e concentrado e outra com cana-de-açúcar e concentrado contendo grãos de girassol. Os teores de umidade, proteína e minerais no músculo não diferiram entre as dietas e as condições sexuais dos animais. A carne de novilhos terminados com a dieta com grãos de girassol apresentou maior teor de lipídios (3,31%) em comparação à dos animais de outras categorias. Os animais que receberam a dieta com grãos de girassol apresentaram maiores concentrações de ácido linoléico conjugado (18:2 cis9, trans-11) (0,73%) e ácidos graxos poliinsaturados (8,12%) no músculo, e também relações mais elevadas de ácidos graxos insaturados:saturados (0,93) e ácidos graxos poliinsaturados:saturados (0,16) em comparação àqueles que receberam a dieta convencional, à base de silagem de milho (0,34%; 6,31%; 0,86; e 0,11, respectivamente). A composição em ácidos graxos da carne de bovinos pode ser melhorada com a utilização de cana-de-açúcar e grãos de girassol na dieta dos animais terminados em confinamento.Palavras-chave: ácidos graxos insaturados, ácidos graxos saturados, ácido linoléico conjugado Chemical traits and fatty acids composition of beef from young bulls, steers and heifers fed corn silage and concentrate or sugarcane and concentrate with sunflower grains ABSTRACT -The objective in this work was to evaluate the chemical characteristics and the fatty acids composition of beef loin (Longissimus muscle) of young bulls, steers and heifers of Canchim breed. The animals were finished in feedlot system and fed two experimental diets, one with corn silage and concentrate (SIL) and the other with sugar cane, as exclusive roughage, and concentrate containing sunflower grains (CNA). Differences were not detected in relation to moisture, protein and mineral contents between diets or sexual categories. The meat from steers that received the CNA diet had higher lipid content (3.31%) in relation to meat from young bulls and heifers receiving the same diet. The meat from animals that received the CNA diet had higher concentrations of conjugated linoleic acid (18:2 cis-9, trans-11) and polyunsaturated fatty acids, and showed higher unsaturated fatty acids:saturated fatty acids and polyunsaturated fatty acids:saturated fatty acids ratios than those of animals fed with SIL diet; respectively 0.73 and 0.34%; 8.12 and 6.31%; 0.93 and 0.86; 0.16 and 0.11. The fatty acids composition in meat from beef cattle can be improved with the utilization of sugar cane and sunflower grains in the finishing diet.Key Words: conjugated linoleic acid, saturated fatty acids, unsaturated fatty acids IntroduçãoAtualmente, a pesquisa tem evoluído em investigações para melhorar a qualidade da carne bovina, conquistar o consumidor e ampliar a competição com as carnes de aves e suínos.

“…The nutritional requirements for maintenance increase because it is a characteristic associated with body weight; furthermore, adipose tissue requires 2.5 times more nutrition. Fernandes et al (2007) fed Canchim heifers in confinement with two different diets. One diet was composed of sugar cane and sunflower seed, and the other diet was based on corn silage and soybean meal.…”

“…The experimental diets were formulated to provide a dry matter (DM) intake of 23.0 g/kg of body weight and gain of 1.20 kg/d, which was obtained by the RLM Software ® / ESALQ-USP (1999) according to the CNCPS system developed by Fox et al (1992).…”

-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.
