Effect of Tankage on The Flavor of Milk

South Dakota State College, Brookings

ABSTRACT

Tankage is not ordinarily fed to dairy cows but during the 1934–35 feeding season many dairymen fed it as a protein supplement because of its relatively low price. We became interested in and organized a trial to determine the effect of tankage on the flavor of milk.

We experienced difficulty in getting the cows to eat tankage. Some cows refused their grain when as little as a tablespoonful of tankage was mixed with eight to ten pounds of the concentrate mixture. We selected four cows from 32 which would eat the tankage in large quantities when mixed with the concentrate part of the ration. In the group of four cows was one Jersey, one Ayrshire, one Holstein and one cross-bred cow. All had sound udders free from garget. The cows were in approximately the same stage of lactation.

The cows were on the regular herd ration consisting of four parts of oats, four parts of barley, three parts of bran, and two parts of oil meal.
