     605. Dried distillers' grains.—Dried distillers' grains, which are about as bulky as wheat bran, are extensively employed for feeding dairy cattle. Lindsey of the Massachusetts Station⁵⁶ compared this concentrate with gluten feed in trials with 6 cows, covering 2 alternate periods of 4 weeks each. The following table shows the concentrate allowance fed during each period, the roughage thruout the trial consisting of 10.7 lbs. bluegrass hay and 10.7 lbs. rowen hay per head daily: […] [table of yields] […] The ration containing dried distillers' grains produced 6 per ct. more milk than that containing the gluten feed. Hills⁵⁷ of the Vermont Station similarly found that dried distillers' grains produced 5 per ct. more product than dried brewers' grains. A mixture of 1 part wheat bran and 2 parts dried distillers' grains produced 4 per ct. more milk and fat than did dried distillers' grains alone. Dried distillers' grains produced one-eighth more milk and one-sixth more fat than a mixture of equal parts of corn meal and bran. Dried distillers' grains and cottonseed meal proved equally efficient. Dried distillers' rye grains made less milk and butter than did the alcohol grains. Armsby and Risser of the Pennsylvania Station⁵⁸ found that the substitution of dried distillers' grains for an equal weight of a mixture of 3 lbs. of cottonseed meal and 2.5 lbs. of corn meal caused a slight increase in the milk yield. The butter from the distillers'-grains ration was not quite as high in quality as that from the cottonseed meal ration. On the other hand, Billings of the New Jersey Station⁵⁹ reports that the butter from cows fed dried distillers' grains was firm, of good flavor and texture, and very marketable. (282) Hooper of the Kentucky Station⁶⁰ states that some cows must become accustomed to the slightly sour smell and taste of dried distillers' grains before they will eat large allowances. While some cows would readily consume 4 lbs. per head daily when mixed with corn meal, it was necessary to mix the grains with silage to get others to consume them at all.
