HAY AND SILAGE OF RED CLOVER AND DRY SUGAR BEET PULP FOR WINTER FEEDING OF DAIRY COWS
|Germán Klee G.1 y Ernesto Jahn B.2|
An experiment was carried out during two years at Human Experiment Substation Los Angeles, Chile, to determine the best form of combining the same forage (Trifolium pratense L. cv. Quiñequeli), conserved as silage or hay, with dry sugar beet pulp for winter milk production.
Milk production with treatment 1 was 22 and 30% higher (P<0.05) than with treatments 2 and 3, respectively.
During both years, dry matter intake with treatment 1 was higher (P<0.05) than with the other two treatments.
Similar mild productions were obtained with either dry sugar beet pulp or with red clover hay, when both feeds were supplemented with clover silage ad líbitum.
The edible dry matter producer per hectare when forage was harvested as hay was 19% higher than when harvested as silage.
