In South Dakota, research by a South Dakota State University dairy science PhD student shows the energy value of the ethanol co-product distillers grains (DDGS) in dairy feed. Sanjeewa Ranathunga was recognized for his research at the recent annual meeting of the Midwest American Dairy Science Association meetings by receiving the Young Dairy Scholars Award.
Ranathunga’s research revealed that DDGS can be used as an effective energy source to replace high priced corn, thus decreasing feed costs. According to income over feed cost analysis, an economic advantage of $1.42 per cow per day was observed when feeding the 21 percent DDGS diet compared to 0 percent DDGS.
