Replacement of wheat bran with spineless cactus in sugarcane-based diets for st...
Conceição,Maria Gabriela da; Ferreira,Marcelo de Andrade; Campos,José Maurício de Souza; Silva,Janaina de Lima; Detmann,EdenioABSTRACT The effect of replacing wheat bran with spineless cactus (0, 25, 50, 75, and 100%) in sugar cane-based diets on the intake of nutrients, feeding behavior, and rumen digestibility of steers was assessed using digested samples collected from the omasum. Five crossbred steers (1/2 Holstein-Zebu) were fitted with cannulas in the rumen and then assigned to a 5 × 5 Latin square design. Samples of omasal dige...
Evaluation of acid digestion techniques to estimate chromium contents in cattle...
Rocha,Gabriel Cipriano; Palma,Malber Nathan Nobre; Detmann,Edenio; Valadares Filho,Sebastião de CamposThe objective of this work was to evaluate the accuracy of digestion techniques using nitric and perchloric acid at the ratios of 2:1, 3:1, and 4:1 v v-1, in one- or two-step digestion, to estimate chromium contents in cattle feces, using sodium molybdate as a catalyst. Fecal standards containing known chromium contents (0, 2, 4, 6, 8, and 10 g kg-1) were produced from feces of five animals. The chromium conten...
Protein contamination on Klason lignin contents in tropical grasses and legumes
Detmann,Edenio; Franco,Marcia de Oliveira; Gomes,Daiany Íris; Barbosa,Marcília Medrado; Valadares Filho,Sebastião de CamposThe objective of this work was to evaluate the extent of protein contamination on Klason lignin (KL) in tropical grasses and legumes, and to propose an equation to estimate the protein-free content of Klason lignin (KLp). Five grass (30 samples) and 12 legume species (31 samples) were evaluated. Legumes had higher KL contents. Protein contamination was significant in both grasses and legumes, but greater in leg...
Nutritional performance of cattle grazing on low-quality tropical forage supple...
Lazzarini,Ísis; Detmann,Edenio; Paulino,Mário Fonseca; Valadares Filho,Sebastião de Campos; Valadares,Rilene Ferreira Diniz; Oliveira,Fabrício AlbaniThe objective of this work was to evaluate the effects of protein and/or starch supplementation on the nutritional performance of cattle grazing on low-quality tropical forage. Five crossbred steers (Holstein × Gyr) with an average body weight (BW) of 397 kg that were fitted with ruminal and abomasal cannulae were used. The animals were kept in individual signal-grass (Bracharia decumbens) paddocks. Five treatm...
Uso de técnicas de regressão na avaliação, em bovinos de corte, da eficiência d...
Detmann,Edenio; Valadares Filho,Sebastião de Campos; Gionbelli,Mateus Pies; Paulino,Pedro Veiga Rodrigues; Paulino,Mário FonsecaObjetivou-se neste estudo propor e discutir um método de avaliação comparativa da eficiência de conversão do alimento em produto entre dois grupos experimentais de bovinos de corte baseado na utilização de técnicas de regressão. Os procedimentos matemáticos e estatísticos foram desenvolvidos a partir de banco de dados formado pela mensuração do consumo de matéria seca e do ganho médio diário em 380 bovinos zebu...
Evaluation of whey fermented by Enterococcus faecium in consortium with Veilone...
Oliveira,Juliana Silva de; Queiroz,Augusto César de; Mantovani,Hilário Cuquetto; Bayão,Geraldo Fábio Viana; Detmann,Edenio; Santos,Edson MauroThe objective of this study was to evaluate the whey fermented by Enterococcus faecium in consortium with Veilonella parvula on the in vitro growth of ruminal bacteria and as a supplement in the cattle diet. In the in vitro experiment, a randomized design, with the following combinations was used: ruminal bacteria; ruminal bacteria and inactive whey; ruminal bacteria and active whey; and active whey. In the in ...
Evaluation of sodium sulfite and protein correction in analyses of fibrous comp...
Gomes,Daiany Íris; Detmann,Edenio; Valadares Filho,Sebastião de Campos; Mezzomo,Rafael; Souza,Natália Krish de Paiva; Queiroz,Augusto César deThe objective of this study was to evaluate the contents of fibrous compounds in tropical grasses and legumes according to utilization of sodium sulfite in the neutral detergent solution or using a procedure for contaminant protein correction. Samples of ten grasses and ten legumes were used. The contents of neutral detergent fiber were decreased when sodium sulfite was used; however, more prominent reductions ...
Evaluation of mathematical models to describe growth of grazing young bulls
Fernandes,Henrique Jorge; Tedeschi,Luis Orlindo; Paulino,Mário Fonseca; Detmann,Edenio; Paiva,Luisa Melville; Valadares Filho,Sebastião de CamposThe objective of this study was to evaluate the use of different mathematical models to describe growth of grazing beef cattle. Data of 20 Nellore bulls with initial weight of 129±28.1 kg and final weight of 405±62.0 kg were used. The animals were randomly divided into four plots and placed on B. decumbens Stapf pastures. Three plots received concentrate supplement with different protein profiles and the fourth...
Avaliação nutricional, durante a amamentação, de tourinhos em pastejo recebendo...
Fernandes,Henrique Jorge; Paulino,Mário Fonseca; Detmann,Edenio; Valadares Filho,Sebastião de Campos; Silva,Aline Gomes da; Porto,Marlos OliveiraO objetivo neste estudo foi avaliar as condições nutricionais de tourinhos em aleitamento, a pasto, recebendo suplementação com concentrados proteicos durante a época de transição águas-seca. Foram utilizados 52 bezerros mestiços com idade média inicial de 130 dias. Os animais foram distribuídos em quatro lotes, alojados em piquetes de Brachiaria decumbens Stapf junto com suas mães, onde receberam uma das quatr...
In vitro and in situ activity of carboxymethyl cellulase and glutamate dehydrog...
Carvalho,Isabela Pena Carvalho de; Detmann,Edenio; Paulino,Mário Fonseca; Mantovani,Hilário Cuquetto; Valadares Filho,Sebastião de CamposTwo experiments were carried out to evaluate the effect of supplementation with different nitrogenous compounds on the activities of carboxymethil cellulase (CMCase) and glutamate dehydrogenase (GDH). In the first experiment, four treatments were evaluated in vitro: cellulose, cellulose with casein, cellulose with urea, and cellulose with casamino acids. After 6, 12 and 24 hours of incubation, CMCase and GDH ac...
