Vinasse is known as the main source of pollution in the ethanol production industry. Vinasse can be used as a proper ingredient in ruminant nutrition. Due to increased environmental concerns and economic points of view, management of the food processing by-products such as being used as an animal feed alternative has got increased tendency. Using by-products obtained from crops and food leftovers in farm animals feeding may reduce the harmful effects of food industry by-products and improve their profitability and added-value. This is an efficient method to improve the quality of a feed ingredient, which has low quality, to an approximately equal extent to the quality of some high-quality foods such as meat and milk. It will alleviate the livestock feed dependence on the feed ingredients that can be used for human consumption. Vinasse contains high amounts of salts, yeast, and organic matter remarkably crude protein. It has brown color and an acidic pH ranging from 4 to 5. The high content of vinasse protein, which consists of non-essential amino acids, has high digestibility that could improve the animal's performance. Probiotic properties and yeast found in vinasse could prevent the replacement of pathogenic micro-organisms in the intestine and maintain the intestinal microflora in a normal and balanced condition. The high content of organic acids (including oxalate, lactate, acetate, and malate) and sorbitol caused an improvement in ruminant performance which in turn increases the digestion and utilization of nutrients, Vit D synthesis, Vit C absorption, and other minerals. Thus, the feed metabolism would be facilitated.
