The objective of this study was to evaluate the effect of sugar cane ensilage with different Brix degrees, with or without the addition of 0.5% of calcium oxide (lime) on the chemical composition and fermentation losses of silages. A complete random design in a 9 × 2 factorial arrangement was used. Experimental silos were used, ensilage was done every 15 days with Brix measuring, and they were opened after 30 days of fermentation. As the Brix degree of the ensiled […]

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 […]

This work was developed to evaluate intake, apparent digestibility of nutrients and the effect of time (days) of total collection (two and four days) in apparent digestibility estimate in goats fed diets containing sugar cane treated with calcium oxide (CaO). Eight castrated male Saanen breed goats, at 22.6 kg average body weight and at four months of age were used, distributed in two 4 × 4 Latin squares, with four 14-day experimental periods. The diets were formulated to be isoprotein […]

Chemical treatment of roughage has been the aim of studies for a long time. However, until nowadays, many questions are arisen due to the efficiency of additives used in relation to the variation of answers, either in nutritive value of treated roughage or in performance of animals feed with diet containing such roughage. This revision will approach the main and most used products, which are anhydrous ammonia, urea, sodium hydroxide and calcium oxide. It has been noticed that ammonization (both […]

Feeding animals with agro-residues may reduce costs and environmental concerns. The agroindustrial wastes used as ruminant feeding are an alternative for ambient problems caused by it accumulation. This study aimed to evaluate chemical additives on the ensilage of residues of pupunha palm (Bactris gasipaes, Kunth) production. Experimental silos (20 L buckets) were used equipped with meters to determine gas and effluent DM losses. The experimental treatments were: control (no additives); urea (1% – wet basis) and calcium oxide (1% WB). […]

The objective of this experiment was to evaluate the susceptibility to aerobic deterioration and dry matter losses of fresh sugarcane and silages with or without chemical additives, and diets composed formulated with these bulks. The experiments were conducted in a complete randomized design with four replications, consisting of fresh or ensilaged sugarcane with calcium oxide or limestone at the level of 1% fresh matter. The aerobic stability was assessed of the bulks and diets by monitoring temperature, pH and dry […]

The objective of this study was to evaluate the effects of chemical additives on the fermentative dynamics and chemical composition of sugarcane silages. The experiment was conducted in a randomized complete design with five replications. Sugarcane was ensiled without additives or with calcium oxide and limestone (1% as-fed basis) constituing three treatments. The fermentative dynamic was analyzed based on gas losses, organic acids and ethanol production and, silages chemical composition. The calcium oxide and limestone treatments showed the lowest values […]

The objective of this trial was to evaluate the effects of chemical additives in the dry matter losses, fermentation profile, and nutritive value of sugar cane silages. The trial was carried out in a completely randomized experimental design with four replicates per treatment. The following additives were applied to the fresh forage during the ensiling: control (without additive), L. buchneri, calcium oxide and calcium carbonate,1.0 and 1.5% (wet basis) each, and calcium sulfate 1.0% (wet basis), all of them diluted […]
