Utilização de grãos secos de destilaria com solúveis (DDGS) na alimentação de bovinos de corte: uma revisão de literatura

Abstract

The use of distillers dried grains with solubles (DDGS) in feeding beef cattle has been the subject of increasing interest in livestock farming. DDGS are co-products of ethanol production and have a nutritional composition rich in energy, protein and a high level of protein not degraded in the rumen, making them an attractive source of food supplementation for beef cattle. In this sense, the objective of this literature review is to evaluate the effects of using distillers' dried grains with solubles (DDGS) in the diet of beef cattle, as well as nutritional composition and its effects on productive performance. DDGS has a nutritional composition suitable for use in beef cattle, with a dry matter content of around 88.79%, crude protein 30.84%, ether extract 11.17%, neutral detergent fiber and acid around 40.06% and 12.83%, respectively. It has beneficial effects on production performance and may influence methane emissions, meat quality, concentrations of fatty acids in meat and reproductive function. However, there are some obstacles to its use.Therefore, it is critical to carefully consider the benefits and challenges associated with using DDGS in beef cattle feeding. Adopting management strategies and diet formulation need to be implemented in a way that maximizes the nutritional benefits of DDGS, while minimizing possible adverse impacts on animal health and performance.
