“…This leads us to believe that low levels (<480 g) of BMB in pearl millet-based diets do not affect the productive performance of feedlot dairy steers. It should be noted that the results obtained in this study were discordant with those reported in the literature (Silva et al, 2012;Cruz et al, 2014;2015a,b). However, it should be clarified that the aforementioned studies were conducted using BMB in corn-based diets instead of pearl millet, used in this study.…”

“…Contributing to this hypothesis, it appears that the NDF intake (12.21 and 11.90 g kg -1 body weight, respectively) at the inclusion levels of 360 and 480 g of BMB exceeds the value (11 g kg -1 body weight) considered the threshold for the occurrence of the intake restriction by the physical limitation of reticulorumen proposed by Mertens (1994). Silva et al (2012) evaluated 0, 20, 40, and 60% of BMB in the concentrate of diets with 44% of mombasa grass silage for Nellore males and Cruz et al (2014) evaluated 0 and 35% of BMB in concentrate fraction of diets with different proportions of concentrate (65 and 71%) for Nellore young bulls and observed a linear increase in DM intake. In these studies, however, the NDF intake was not limiting (<11 g kg −1 body weight) in any of the inclusion levels of the by-product.…”

“…The cost of traditional concentrates based on corn and soybean meal can represent up to 45% of the production cost, varying significantly with the level of concentrate in the diet (Missio et al, 2009). Cruz et al (2014) demonstrated that diets in which the concentrate proportion exceeds the forage, source, amount and commercial value of foods are more important in shaping the cost of production than the manipulation of the amount of forage/concentrate in the diet. This demonstrates the importance of using lower-cost feedstuffs.…”

“…The babassu fruit is used mainly for production of flour and oil for human consumption. The babassu mesocarp bran (BMB) is produced from the mesocarp (23% of the fruit) of babassu and can replace the corn grain without affecting animal performance, but it lowers the feed cost (Silva et al, 2012;Cruz et al, 2014).…”

-The objective of this study was to evaluate the feeding behavior and feedlot productive performance of dairy-origin steers fed for 84 days ground pearl millet grain-based diets with 0, 120, 240, 360, and 480 g kg -1 of babassu mesocarp bran (BMB) and a standard diet based on ground corn. Thirty Holstein-Zebu steers with average initial body weight of 371.02±27 kg were used. The experimental design was completely randomized, with five replications. Dry matter intake showed better fit with the quadratic regression equation with the inclusion of BMB, reaching a maximum value in diets with 360 g of this by-product. There was no difference for dry matter intake between pearl millet-and corn-based diets. There was no difference in total digestible nutrients intake between diets. The digestibility coefficient of organic matter decreased linearly with the increase in the dietary level of BMB. The digestibility coefficient of organic matter was not different between corn and millet diets. There was no difference in feeding time between diets. Total requirement of metabolizable energy increased linearly with inclusion of BMB. However, total requirements of metabolizable energy did not differ between the corn-and pearl millet-based diets. Average daily gain decreased linearly with the increase in BMB, with adjustment forced by the sharp decline of this variable in diets with 480 g of BMB. There was no difference in average daily gain between corn-and pearl millet-based diets. The inclusion of levels above 360 g of babassu mesocarp bran in pearl millet-based diets reduces the supply of metabolizable energy and the productive performance of feedlot dairy steers.

“…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. A textura, o marmoreio, a força ao cisalha...

Production responses in young bulls fed glycerin as a replacement for concentrates in feedlot diets

We assessed the productive performance, blood parameters, and carcass characteristics of young crossbreed dairy bulls kept in feedlots and fed with diets containing 0, 60, 120, and 240 g/kg of crude glycerin, replacing a mixture of ground pearl millet grain (50%) and babassu mesocarp bran (50%). Twenty-four bulls with an average age of 24 months and an average initial weight of 390 ± 31.5 kg were used. The experimental design was completely randomised with six replications. Dry matter and digestible energy intake were not influenced by diets. Feed conversion linearly decreased with increasing glycerin levels. The increase in the levels of glycerin resulted in a linear increase in blood glucose and in average daily weight gain. Carcass weight was not affected, but trimming fat increased and carcass yield decreased linearly, with increasing glycerin levels. The addition of crude glycerin at levels up to 240 g/kg of dry matter to diets containing babassu mesocarp bran and ground pearl millet grain increased the performance of young feedlot bulls, and improved feed efficiency and carcass subcutaneous fat thickness.
