A.S. Series 78-19
The entire aspen tree (except roots) fiber was used successfully as a major component of wintering rations for pregnant stock cows. It was necessary to correct aspen for deficiencies in protein, phosphorus and vitamin A. The stock cows were only in fair to good condition going into the winter feeding period, and their condition remained fairly constant for all feeding groups with normal or below normal animal death losses. Normal, healthy calves were produced in all feeding groups as indicated by birth and weaning weights. Conception was not affected by feed type, although more open cows were present in the hay-fed group.
