Two systems of watering lactating cows were compared at the Experiment Station Remehue in Osorno, Chile: I Water available continuously in the field, and II Water offered to the animals twice daily at the milking parlour. Milk production per day (4% FCM), percentage butterfat and liveweight gains for both treatments were 9.17 and 9.35 Kg; 3.89 and 3.90; and 0.122 and 0.110 Kg, respectively. All these differences were not statistically significant.
The experiment was carried out during the summer. A sward consisting of ryegrass, cocksfoot and white clover was used, and the stocking rate was 1.6 cows per hectare. Treatment II involves an important saving in infrastructure for milk production.
