Dr. Wolf gives an illustration of the standard for a milch cow, by
saying that 30 lbs. of young clover hay will keep a cow in good milk;
and that this contains of dry organic substance, 23 lbs., of which is
digestible--albuminoids 3.21, carbohydrates 11.28, and fat 0.63. This
is .71 lb. albuminoids more, and .22 lb. of carbohydrates less, with
.13 lb. of fat more, than the standard. Then he takes the richest and
best meadow hay, of which 30 lbs. contains of organic substance 23.2
lbs., having digestible--albuminoids 2.49 lbs., carbohydrates 12.75
lbs., and fat 42 lb. This is almost exactly the feeding standard.
As will have been seen by what has preceded, the German standard ration
for a milch cow is 24 lbs. of dry organic substance, containing 2.50
lbs. nitrogenous food, and 12.90 lbs. of carbonaceous food. To secure
this, Dr. Wolff recommends for every 1,000 lbs. of live weight:
12 lbs. average meadow hay.
6 " oat straw.
20 " mangolds.
25 " brewers' grain.
2 " cotton seed cake.
