In San Javier, Bolivia, with a system of dairy ranching where cows are Bilked once per day while raising a calf, it was shown that the grazing of a forage reserve of the legumes Macrotyloma axillare cv Archer and Glycine wightii cvTinaroo raised milk production by 11-20Z. The leguminous protein reserve also consistently increased the butterfat content of the milk by an average of 0.4 percentage points. It was calculated that coring the 5 aunties of the dry season from April to August' one hectare of reserved legume pasture in conjunction with 3 hectares of grass could provide about 50% more grazing than 4 hectares of unimproved grass. Suitable dry season stocking rates for good levels of production without problems of overgrazing are about 1.2 and 0.8 cows per hectare respectively for the protein reserve system and the unimproved traditional pasture
