STUDY EVALUATES
HAY IN RATION
Though there has been a trend to
high -moisture feeds, many dairy farm-
ers still prefer to feed a bit of dry hay to
their cows. A trial at the University of
Guelph has evaluated the effect of add-
ing hay to a haylage high -moisture corn
ration. The hay was either long hay fed
before the grains or chopped hay mixed
with good quality alfalfa haylage.
Results indicate that adding hay did
increase production (above one kg/day
in the test), and there was no significant
difference between long and chopped
hay. The milk composition did not
change. Rumination time did increase,
as did the duration of meals and the
intensity of chewing. The response to
hay is believed to be an improved rumen
environment rather than more rumina-
tion. Feeding hay is expected to yield a
better response as the haylage quality
increases or if corn silage is fed as the
roughage.
In a related experiment, the fibre
level and roughage:concentrate level in
a haylage high -moisture corn diet was
evaluated. The roughage:concentrate
level was varied by adjusting the silage
and grain levels. As one would expect,
increasing the fibre and roughage: con-
centrate decreased milk production.
The increased fibre resulted in a signifi-
cant increase in fat test and increased
chewing, eating, and ruminating time.
At any fibre level, the introduction of
dry hay increased milk production (by
about one kg/day).
With a haylage high -moisture corn
ration, the addition of some hay did
improve production in these trials in
spite of the fact that the haylage was
replaced by a lower quality feed.0
