The Yield and Composition of Milk from Aberdeen-Angus Cows

Cows of the specialized beef breeds are seldom tested for milk production and consequently very little is known about the actual milk yield and: its variation within these breeds. A search through the literature for data on the yield and composition of milk from purebred Aberdeen-Angus cows has given very meager resulis. Gowen (5, One cow produced in one year 2,852 pounds of milk, and two others produeed in .eight months 1,065.9 pounds of milk with 4.40 per cent of butterfat, and 1,569.3 pounds milk with 6.66 per cent butterfat, respectively. The average percentage of butterfat for the Aberdeen-Angus cows of the Maine experimental herd is said to be 4.4, with considerable range on either side of this point.
