Three Holstein steers, canulated in the rumen, where were incubated nylon bags with sugarcane bagasse, were maintained in feedlot, in individual boxes, according to the following treatments: T1 – bagasse without treatment (control); T2 – bagasse treated with 2.5% Na2S; T3 – bagasse treated with 4% NH3 and T4 – bagasse treated with 2.5% Na2S + 4% NH3. Higher potential degradability was observed for the treatment with bagasse treated with NH3 and NH3 plus Na2S. Dry matter degradability ranged from […]

Sixteen ½ Holstein/Indubrasil heifers, averaging 230 kg of live weight, housed in individual boxes, were allotted to a completely randomized design, with four treatments and four replicates, according to the following treatments: T1 – bagasse without treatment (control); T2 – bagasse treated with 2.5% Na2S; T3 – bagasse treated with 4% NH3 and T4 – bagasse treated with 2.5% Na2S + 4% NH3. All treatments were based on bagasse dry matter. Sugarcane bagasse was stored for 10 months e, after […]

Sugarcane bagasse with 55% of dry matter (DM) was treated with five levels of urea (0, 2.5, 5, 7.5, and 10%) and 5% ground whole soybean as a source of urease both, on a DM basis. The material was stored in plastic bags for 97 days (8 kg/ 50 L plastic bag), and after plastic bag opening, samples were collected at three aeration period (2, 9, and 16 days). A completely randomized design with three replicates was used. There was […]

The objective of this work was to evaluate the effect of the addition of crescent levels of urea, with or without urease, on sugarcane bagasse nutritive value. The experimental design was a completely randomized design in a factorial arrangement (4 x 2) + 1 (control), with four replicates. The evaluated factors were urea levels (2.0, 4.0, 6.0 and 8.0% DM), urease levels (presence – 20% of urea fresh matter – and absence) and a control treatment (0.0% urea and without […]
