“…In this context, millet grain can be utilized at times when corn prices are on the rise, replacing it totally or partially in the cattle diet. This strategy in diet formulation allows for reduction in feed cost in the feedlot while maintaining animal performance and carcass characteristics similar to those obtained with the corn grain diet ALENCAR et al, 2015).…”

Assessment of carcass and meat characteristics of Nellore young bulls finished in feedlot with crude glycerin levels (0, 60, 120, and 240 g kg -1 dry matter) in millet-based diets. Twenty-eight young bulls with mean age of 18 months and average weight of 357 ± 23.56 kg were used. The animals were distributed in a completely randomized design with four treatments and seven replicates. It was observed that the physical composition and edible portion of the carcass were not affected by crude glycerin levels in the diets. However, the increased dietary crude glycerin level raised the weights of the forequarters (kg and % of cold carcass weight), but not that of the pistol cut and short ribs. Among the commercial cuts prepared to marketing of the pistol cut, only the weight of the rump cap (% cold carcass weight) was changed, decreasing linearly with increasing dietary crude glycerin levels. Additionally, meat characteristics remained unaltered by the increased levels of crude glycerin. It was concluded that inclusion of up to 240 g kg -1 of crude glycerin in millet grain-based diets for Nellore young bulls finished in feedlot does not alter the main carcass and meat characteristics or affect their economic value.

ResumoO objetivo do presente estudo foi avaliar as características de carcaça e carne de tourinhos Nelore terminados em confinamento com níveis de glicerina bruta (0, 60, 120 e 240 g kg -1 da matéria seca) em dietas a base de grão de milheto. Vinte e oito tourinhos com idade média de 18 meses e peso corporal médio de 357 ± 23,56 kg foram utilizados. O delineamento experimental utilizado foi o inteiramente casualizado com quatro tratamentos e sete repetições. A composição física e a porção comestível da carcaça não foram alteradas pelos níveis de glicerina bruta da deita. A elevação do nível de glicerina bruta das dietas elevou o peso (kg e % do peso de carcaça fria) do dianteiro, mas não alterou os pesos (kg e % do peso de carcaça fria) do traseiro especial e da ponta de agulha. Dentre os cortes comerciais preparados para comercialização do traseiro especial apenas o peso da picanha (% peso de carcaça fria) foi alterado com o avanço do nível de glicerina bruta das dietas, diminuindo linearmente. As características da carne não foram alteradas pelo aumento do nível de glicerina bruta das deitas. A inclusão de até 240 g kg -1 de glicerina bruta em dietas a base de grão de milheto não altera as principais características de carcaça e carne com importância econômica. Palavras-chave: Cor.

“…In this study, the lack of variations in DM intake with inclusion of BMB might be associated with the inclusion levels of this byproduct that ranged from 7.7 to 11.18% and from 16.43 to 23.81% in the diets with high and low proportions of sugarcane, respectively. Changes in DM intake with the inclusion of BMB in the cattle diets were found when the levels of this byproduct reached values higher than 25% of the diet dry matter (Cruz et al, 2014;Alencar et al, 2015). The high indigestible fiber content and low passage rate of sugarcane may have contributed to the obtained results, altering the transit of BMB through the reticulorumen (reducing its output) due to fiber entanglement.…”

“…As for the animal response to BMB inclusion in diets, the literature (Silva et al, 2012;Cruz et al, 2014;Santana et al, 2015) shows that when inclusion levels are low to moderate (226.8 to 422.4 g/kg of the diet DM), no changes in animal performance are observed, reflecting the similar energy intake. Nevertheless, Miotto et al (2013) and Alencar et al (2015) showed that the average daily gain of feedlot cattle began to show a significant decline as the inclusion of BMB approached 500 g/kg of diet dry matter, after which the energy intake did not support the maintenance of animal performance.…”

“…Research carried out with this byproduct in ruminant has focused mainly on inclusion levels replacing corn grain in diets (Miotto et al, 2012;Silva et al, 2012) and recently evolved to the assessment of this feed replacing corn in diets with different levels of concentrate (Cruz et al, 2014) and/or associated with the processing of corn grain (Santana et al, 2015). Recently, because of the good results when used in moderate dietary inclusion levels, this byproduct has been evaluated in association with other feedstuffs, e.g., pearl millet (Alencar et al, 2015). Overall, results from these studies have shown that, at moderate levels in diets, BMB provides similar animal performance and carcass traits in relation to corn, lowering the feed cost (Cruz et al, 2014(Cruz et al, , 2015Alencar et al, 2016).…”

The objective of this study was to evaluate the production performance of feedlot cattle fed diets containing chopped sugarcane ratios (580 or 380 g/kg of diet dry matter) as roughage and levels of inclusion of babassu mesocarp bran (BMB; 420 to 620 g/kg of concentrate dry matter). Twenty-four young Nellore bulls with 321±23 kg initial body weight, at 22 months of age, were used in a completely randomized experimental design with treatments in a 2 × 2 factorial arrangement and six replicates. Dry matter intake (21.71 g/kg of body weight), average daily gain (1.46 kg/day), and cold carcass weight (232.59 kg) were not changed by proportion of sugarcane or BMB level. The proportions of sugarcane and BMB levels did not change the apparent digestibility of the diets, except the digestibility of neutral detergent fiber, which was lower in the diet associating the lowest levels of sugarcane and BMB. Increasing proportions of sugarcane reduced subcutaneous fat thickness from 2.89 to 1.91 mm. Carcass commercial primal cuts were not affected by variation factors. Inclusion of babassu mesocarp bran enables the use of larger proportions of sugarcane as a result of the increased digestibility of the fiber fraction of feedlot cattle diets without changing the performance and main carcass traits of these animals.

“…Among feedstuffs to substitute corn grain at times when this commodity is found at high prices, millet grain and babassu mesocarp bran are noteworthy alternatives. The use of these feedstuffs in cattle diets has allowed the reduction of feed costs, with animal performance and carcass characteristics remaining similar to those obtained with corn grain (CRUZ et al, 2014(CRUZ et al, , 2015ALENCAR et al, 2015).…”

Assessment of carcass and meat characteristics of Holstein-Zebu crossbred young bulls finished in feedlot with crude glycerin levels (0, 60, 120, and 240 g kg -1 dry matter) in replace of ground pearl millet grain and babassu mesocarp bran mixture-based diets. Twenty four bulls 30-month-old and initial average body weight of 390 ± 31.5 kg were used. The animals were distributed in a completely randomized design with four treatments and six replicates. The absolute weight (kg) of commercial cuts did not fit any of the tested regression models. However, the weight of the short ribs and the pistol cut were higher for animals fed with crude glycerin in relation to those fed without inclusion of this food in the diet. The proportion of the commercial cuts, however, was not changed. The increase of the crude glycerin levels linearly increased the proportion of carcass fat and reduced the muscle proportion, without changing the proportion of bone and the edible portion of the carcasses. The ratio muscle/fat reduced linearly with the advance of crude glycerin level of diets. The color of the meat, evaluated subjectively, increased linearly with the advance of crude glycerin levels of the diets, from dark red to slightly dark red. The texture, marbling, shear force, thawing loss and cooking loss were not changed by dietary levels of crude glycerin. The inclusion of up to 240 g kg -1 of crude glycerin in the diets increases the proportion of fat without changing the marketable portion of carcasses. The benefits to the meat quality refer to the improvement of color, without changing the other characteristics of economic interest. ResumoO estudo objetivou avaliar a composição física da carcaça e as características da carne de tourinhos alimentados com níveis de glicerina bruta (0, 120, 240 e 360 g kg -1 de matéria seca) em dietas a base de grão de milheto moído e farelo do mesocarpo do babaçu. Foram utilizados 24 tourinhos mestiços Holandês-Zebu com 30 meses de idade e 390 ± 31,5 kg de peso corporal médio inicial. O delineamento experimental foi o inteiramente casualizado com quatro tratamentos e seis repetições. Os pesos absolutos (kg) dos cortes comerciais não se ajustaram a nenhum dos modelos de regressão testados. Entretanto, verificouse que o peso da ponta de agulha e do traseiro especial foram maiores para os animais alimentados com glicerina bruta em relação àqueles alimentados sem inclusão deste alimento na dieta. A proporção dos cortes comerciais, no entanto, não foi alterada. A elevação do nível de glicerina bruta das dietas elevou linearmente a proporção de gordura das carcaças, reduzindo a proporção de músculo, mas não alterou a proporção de osso e a porção comestível das carcaças. A relação músculo/gordura foi reduzida linearmente com o avanço do nível de glicerina bruta das dietas. A coloração da carne, avaliada subjetivamente, aumentou linearmente com o avanço do nível de glicerina bruta das dietas, passando de vermelho escuro para vermelho levemente escuro.
