Silage and milk production comparisons between hays of different digestibilities as silage supplements



Silage and milk production comparisons between hays of different digestibilities as silage supplements



Grass and Forage Science 37(2): 129-138



In 3 separate feeding experiments using a total of 30 individually-housed Ayrshire cows, 3 silages made from perennial ryegrass were given ad lib together with supplements of 4 different hays in the long form. The in vitro D [digestibility]-values of the silages ranged from 0.598-0.683 and the hays from 0,580-0.700. The daily intake of hay DM [dry matter] varied from 0.8-4.1 kg/cow and was given either without or with a daily maximum of 2.4 kg concentrate DM containing 379-527 g CP [crude protein]/kg DM. On average, 1 kg hay DM decreased silage intake by 0.84 kg DM with a range of 0.61-1.00 kg. The hay supplements had only small and non-significant effects on total DM intake, milk yield and milk composition but increased the daily intake of drinking water. In 3 behavioral studies, the eating and ruminating times expressed as min per kg DM did not differ significantly between the various supplement treatments. Hay has only a marginal value as a supplement for grass silage, although the hay could serve as a useful buffer feed if the amount of silage was limited.
