    The global increase in food demand and rising costs of production forces the agricultural industry to search for cheaper and more efficient methods of food provision. A partial solution to this problem could be the use of a high-protein feed of an industrial origin in livestock nutrition, such as corn dried distillers grains with solubles (DDGS). Since DDGS is a byproduct, arising as a result of bioethanol production from corn, including it to ratio could be an excellent way of its natural utilization. There are indications that DDGS may favorably affect the rumen fermentation profile, inter alia, by increasing the total production of volatile fatty acids and changing the ratio between some of acids. Other reports relate to the reduction of greenhouse gases emitted by ruminants. Regarding the high calorific value of methane, the reduction of methanogenesis is an extremely beneficial phenomenon for grazers, because it allows to reduce energy losses associated with emission of fermentation gases. Due to the large heat capacity, it is believed that methane has a great influence on global warming. Therefore, another advantage of inhibiting methane production is reduced amount of gas in the atmosphere. However, the effect exerted on the fermentation following DDGS insertion into diet is not carefully examined, particularly in relation to the sheep, and the results are often conflicting. For that reason, there is a need for further research, gathering knowledge and verify whether the use of DDGS in the ratio of sheep is actually the convergent goal from ecological and productive point of view.
