Extract

Four cows, all giving milk low in solids-not-fat, were used for the experiment:

1. The change from winter rations to pasture produced a decided increase in the solids-not-fat percentage and milk yield.

2. Well-balanced rations fed to the cows during two lactations showed a small rise in the milk yield and solids-not-fat during the second lactation, but did not increase the solids-not-fat to above the 8·50 per cent, limit.

3. Feeding a high protein ration of albuminoid ratio 1:2·76 produced no change in milk yield or casein, decreased the solids-not-fat and lactose, and increased the total milk nitrogen and albumin and globulin nitrogen.

4. Feeding a high carbohydrate ration of albuminoid ratio 1:9·90 did not affect milk yield, fat or ash, but decreased slightly the solids-not-fat.
