Within 10 days of feeding Soyex to my milking cows, the milk protein increased 0.2 and the fat also increased 0.2. I mix the Soyex with soybean meal, high moisture corn, corn silage, alfalfa haylage and straw. The cows like the feed and its palatability. Soyex provides a higher source of energy than soybean meal and is a great source of protein. In addition, Soyex is also very economical. I am very happy with Soyex!
