Abstract

Sustainability of agricultural systems through protein supplementation of low quality forages H.E. Laborde''*, M.I. Amela', M.B. Torrea', R.E. Brevedan''* & H.

Abstract In agricultural systems where land is used alternatively for wheat-soybean production and cow-calf operations, great amounts of wheat straw are available for ruminant nutrition. As a sole feed, wheat straw provokes severe body weight losses of pregnant cows during the breeding season. Whole soybean grain which is available at the farm level, could be used as a protein supplement for improving wheat straw utilization The objective of this study was to evaluate the effect of ground small seeds of soybean (GSS) and urea on average daily Hveweight gain (ADG) of heifers fed
