The objective of the present research was to evaluate performance, digestibility and consumption of cattle receiving diets based on in natura or hydrolyzed sugar cane, with two concentrations of calcium hydroxide. Eighteen Nelore steers with approximately 390 kg of body weight were distributed in a randomized block design, based on live weight. Animals received complete diets containing 70% roughage (sugar cane in natura, and hydrolyzed treated with calcium hydroxide at 0.5% or 0.9%), and 30% concentrate. Diets were formulated to […]

The objective of this work was to evaluate the effect of whitewash addition and the times after application on aerobic stability and growth of microorganisms (fungi and yeasts) in fresh sugarcane. It was used a completely randomized experimental design, with four replications. Aerobic stability (temperature) and the concentrations of yeast and fungus and pH were evaluated in a split-splot scheme with five doses of whitewash (0; 0.5; 1.0; 1.5 and 2.0%) and five times after treatment (0, 24, 48, 72 […]

Four crossbred bovines (Zebu x Holstein) fed in nature, hydrolyzed, hydrolyzed sugar cane hay and silage as roughage sources constituting 70% of the diets were used to study the effect of alkali treatment of sugar cane (1.5% of NaOH at 50%) on dietary total digestibility and dry matter intake and rate of passage of sugar canes. The fiber was the most influenced fraction by the alkali treatment and increased at least by 45% of digestibility. The increases of 25.0 and […]
