Effect of regrowth interval and a microbial inoculant on the fermentation profi...
Pereira, O. G.; Garcia, R.; Silva, T. C.; Oliveira, J. S.; Ferreira, C. L. L. F.; Santos, E. M.The objectives of this study were to characterize and quantify the microbial populations in guinea grass (Panicum maximum Jacq. cultivar Mombasa) harvested at different regrowth intervals (35, 45, 55, and 65 d). The chemical composition and fermentation profile of silages (after 60 d) with or without the addition of a microbial inoculant were also analyzed. Before ensiling, samples of the plants were used for t...
Does sugar cane ensiled with calcium oxide affect intake, digestibility, perfor...
Chizzotti, F. H. M.; Pereira, O. G.; Valadares Filho, S. C.; Chizzotti, M. L.; Rodrigues, R. T. S.; Tedeschi, L. O.; Silva, T. C.Two trials were conducted to evaluate how calcium oxide (CaO) as an additive in sugar cane silage affects animal performance and diet digestibility. Experiment 1 included 35 crossbred steers (Holstein × Nellore) with an average body weight (BW) of 350 ± 18.3 kg, which were distributed across a randomized block design with five treatments and seven replicates. The five treatments consisted of sugar cane ensiled ...

Pereira, O. G.; Valadares Filho, S. C.; Leão, M. I.; Pereira, D. H.; Tedeschi, L. O.; Chizzotti, F. H. M.; Chizzotti, M. L.Realizou-se um estudo com quatro novilhos cruzados Holandês x Nelore (225±22kg de peso vivo), canulados no rúmen e abomaso, distribuídos em quadrado latino 4 x 4 para avaliar o efeito de diferentes proporções de silagem de Braquiária brizantha e silagem de sorgo sobre o consumo e a digestibilidade dos nutrientes no trato digestório total e parcial, sobre os parâmetros ruminais e sobre a eficiência microbiana. A...
Utilization of castor bean meal treated with calcium hydroxide, fed wet or dry,...
Gionbelli, T. R. S.; Veloso, C. M.; Gionbelli, M. P.; Novais, M. A. S.; Silva, A. L.; Espechit, C. J. B.; Campos, J. M. S.; Valadares Filho, S. C.Effects of replacement of soybean meal by wet or dry castor bean meal (CM) in diets of feedlot lambs on animal performance, carcass traits, intake, digestibility and hepatic function were assessed. Thirty-five mixed-breed woolless lambs averaging 20±0.26 kg body weight were randomly assigned into five treatments in a 2×2+1 factorial design with 7 animals per treatment. Control animals were fed a diet containing...
Intake and ruminal digestion determined using omasal and reticular digesta samp...
Mariz, L. D. S.; Valadares Filho, S. C.; Detmann, E.; Pereira, O. G.; Pereira, L. G. R.; Marcondes, M. I.; Santos, S. A.; Villadiego, F. A. C.Sugar cane is widely used in an in natura forage in tropical countries, but the adoption of silage methods facilitates the preservation of its nutritional value and improves the logistics of its use. To explain differences in performance using alternative forages, it is important to conduct studies that evaluate the various digestion sites for the nutrients provided in diets. However, considering that the colle...
Digestibility and microbial efficiency in steers fed diets based on corn silage...
Chizzotti, F. H. M.; Pereira, O. G.; Valadares Filho, S. C.; Leão, M. I.; Ribeiro, K. G.Avaliou-se, em um esquema fatorial 2x2, o efeito de silagem de milho de diferentes híbridos e da porcentagem de concentrado (25 ou 50%) sobre o consumo e a digestibilidade de nutrientes, os parâmetros ruminais e a síntese de proteína microbiana em bovinos. Utilizaram-se quatro novilhos cruzados (HxZ) - (512±25kg) -, fistulados no rúmen e no abomaso, os quais foram distribuídos em um quadrado latino 4x4. Os trat...

Silva, L. D. da; Pereira, O. G.; Valadares Filho, S. C.; Ribeiro, K. G.; Valadares, R. F. D.; Silva, T. C.; Santos, S. A.The effects of dietary substitution of soybean meal (SBM) with ethanol-treated jatropha kernel cake with seed shells (TJC) on nutrient intake and digestibility, nitrogen balance, pH, rumen ammonia nitrogen (NH3–N), serum levels of alanine aminotransferase (ALT, EC 2.6.1.2) and aspartate aminotransferase (AST, EC 2.6.1.1), and ruminal degradation kinetics of SBM and TJC crude protein (CP) in Holstein heifers wer...

Pereira, O. G.; Chizzotti, F. H. M.; Valadares Filho, S. C.; Tedeschi, L. O.; Ribeiro, K. G.; Pereira, D. H.Avaliaram-se, em esquema factorial 2x2, o efeito das silagens de dois híbridos de milho (A: Agromen - AGN35-A42; B:Bayer - A3663) e dois níveis de concentrado (25 e 50%) sobre o desempenho animal. Para avaliar o consumo, a digestibilidade e o desempenho animal, utilizaram-se 24 novilhos cruzados, Holandês x Zebu, com média de peso de 335±30kg, distribuídos em seis blocos ao acaso. Os tratamentos consistiram em ...
Effects of lactic acid bacteria with bacteriocinogenic potential on the ferment...
Silva, V. P.; Pereira, O. G.; Leandro, E. S.; Silva, T. C. Da; Ribeiro, K. G.; Mantovani, H. C.; Santos, S. A.The fermentation profile, chemical composition, and microbial populations of alfalfa silages treated with microbial inoculants (MI) at different fermentation periods (T) were evaluated in tropical conditions. A 4 × 6 factorial arrangement was used in a randomized design with 3 replicates. Fresh alfalfa was treated with (1) no treatment (CTRL), (2) commercial inoculant (CIN), (3) Pediococcus acidilactici (strain...

Ribeiro, K. G.; Valadares Filho, S. C; Pereira, O. G.; Rennó, L.N.; Santos, R. S.; Villela, S. D. J; Silva, J. L.Two experiments were conducted to evaluate the effects of diets containing two levels of crude protein (CP) and concentrates on the intake, total nutrient digestibility, nitrogen balance (NB), microbial efficiency, and performance of lambs. The diets consisted of 10% or 14.25% CP and 40% or 60% concentrate, with corn silage as the forage. In the digestibility assay, four intact male F1 Santa Ines×Texel lambs, w...
