It is difficult to produce milk or meat from average hay unless it is soaked
in water-diluted molasses, or -
� The quality is exceptional as when containing mostly leaf with few
stems and at least 30% legumes.
� It is made from perennial ryegrass or endophyte-free tall fescue and
clover no more than 3,000 kg dry matter/ha or lb/acre which is about 25 cm
(10 inches) high, and cut with a lacerator with a hay chute and haybar*
after at least four hours of sunshine, then turned each time the top is
drier than the bottom. The last turnings should put it into windrows. This
halves drying time which improves the feed value and palatability compared
with cutterbar or disc-mown hay. Cows relish a certain amount of lacerated
hay, but always need some greens.
*A haybar of 5 cm inside diameter pipe is bolted to the bottom front of a
heavy flail type lacerator forage harvestor so it bends the pasture over to
5 cm from ground level so it gets cut off at that height and is dragged
around the haybar to lacerate it, but is not cut into shorter lengths. The
lacerator leaves the hay spread out for fast drying. Turn it as soon as it
is drier on top than underneath. A haybar reduces the power requirements so
a mowing tractor can travel about 50% faster. This system makes full length
hay that packs more tightly in bales. Baler pressure adjustments may have to
be loosened. Animals like it so much that they turn up their noses at other
hay. If you have both, feed the other hay until it is all finished. If you
feed poor quality hay then good quality hay each day, in two days animals
will learn to wait for the good.
25 cm (10 inch ) high grass and clover hay lacerated pre-flowering and baled
within 36 hours has a feed value almost as good as grain and more minerals.
Good quality hay can reduce the requirement for grain or concentrates and
give healthier animals than those fed too much grain, even with over-mature
hay or with too much very short (< 15 cm) immature pasture. Good hay is also
valuable for rearing calves to build their rumen.
As pasture grows in height above 25 cm (10 inches) it decreases in feed
value. Add to this taking longer to dry so it loses feed value and the net
animal production per hectare or acre cut doesn�t increase, in fact can
decrease if they eat less of a poorer quality feed.
When invited to Cornell University in 1982 they were making hay from 90 cm
(three feet) high mainly orchard grass with no clover at that height, so I
pointed out to them that it was �bedding� and a reason they had to feed so
much grain to get animal production. The crude protein of lacerated 25 cm
tall hay can be double that of 90 cm clover-less hay which costs twice as
much per kg of protein.
If you have both, feed the other hay until it is all finished. If you feed
poor quality hay then good quality hay each day, in two days animals will
learn to wait for the good.
