The objective of this study was to estimate the dehydration curve and occurrence of fungi and mycotoxins in Tifton 85 hay. The experimental design was randomized blocks in split plots with four replications and five levels of nitrogen (0, 25, 50, 75 and 100 kg ha-1) in the form of urea, two regrowth ages (28 and 35 days) and drying hay in the sun and in shed. After harvesting, the grass was sampled four times (0, 8, 23 and 32 […]

The suitable evaluation of nutritional value of forages depends on the adoption of appropriate methodologies. Forage quality is highly dependent of fermentation products, in case of silage, and the losses of soluble compounds and microorganisms activity in the case of hay. The theme “Methodological advances in evaluation of preserved forage quality” at the 44th Annual Meeting of Brazilian Society of Animal Science has as main goals to highlight the more useful and particular methodological procedures for conserved forages and additional […]

This experiment had as objective to evaluate protein fermentation of three nitrogen sources (trypticase, soybean meal and fish meal), with or without monensin or propolis extract addition. Incubations were done by using 7.2 mL of McDougall buffer, 2.0 mL of inocula, 0.2 mL of ethanolic solution with or without monensin or propolis and 84.4, 150 or 112.5 mg/10 mL of trypticase, soybean meal and fish meal, respectively, in a 3×3 factorial arranjement. The flasks were incubated anaerobically at 39ºC in […]
