Show hard to explain reason for variation in gains it has been experimentally demonstrated that dairy dalry heifers heffers liberally fed during the winter malting making gains con above normal will make gains considerably below normal the following summer on grass why this Is so no one seems to have given a satisfactory explanation this tact fact was clearly demonstrated by the results of feeding trials reported recently by the west virginia station in four comparisons of three groups of heifers heffers one group for two pasture seasons that were self fed grain and given free access to roughage the average winter gain was lbs ibs per head whereas the same helfers gained only lbs ibs per head on pasture no grain was fed on pasture similar heifers heffers band handled fed averaged 1524 lbs ibs per head for the winter feeding periods and lbs ibs per head during the pasture season no grata grain was fed on pasture |
