Silagem de cana-de-açúcar: revisão de literatura

Abstract

With the growing increase in Brazilian livestock, in which the grazing system is still predominant, there are some problems due to the productive seasonality of pastures. With this, alternatives are increasingly sought for fodder for animal supplementation, because these are the main source of food for ruminants. Sugarcane has been used as a source of feed due to its high dry matter productivity, as well as the ease of planting, and its maturation phase occurs respectively in the months of scarcity of other forages. Silage production involves several factors, such as: choosing the right forage, cultivating the forage, cutting the forage at the right time, chopping the plants to the right size, as well as good compacting and sealing the silo. When properly performed, ensiling controls microbial activity by forming an anaerobic environment through the natural fermentation of sugars by lactic acid bacteria present in the crop. For sugarcane silage, the use of additives may be necessary in order to reduce quantitative and qualitative losses during the fermentation process and in the postopening period. mong the main additives used in the production of sugarcane silage we can highlight moisture absorbents, microbiological inoculants and chemical additives. In animal feed, sugar cane in natura, or its silage, can be used as a source of volume in the diet. The use of sugarcane by-products shows a great advance towards the sustainability of animal production systems. The present study aims to carry out a review on the use of sugarcane in the production of silage and animal feed.
