The Huron Expositor, 1988-05-25, Page 19Feed management changes prevent
Pastured dairy cattle need the same
nutrients they receive in a stored feeding
program. The changes in forage quality
often make it necessary to make.changes in
the grain ration. For many dairymen, the
sudden introduction of lush palatable young
grasses also results in serious problems
with low fat test, reduced grain intake, and
lower milk production.
Preventing these problems usually means
changes in feed management, and making
sure the ration stays as balanced as possi-
ble. The dry matter of voting grasses may
contain.as much as 15 to 16 per cent protein
and 60 to 64 per cent T.D.N., but the high
moisture .content means that cows would
have to eat more than 100 kg. of pasture to
reach the same dry matter intake as from 14
kg. of hay. Many cows will actually con-
sume these amounts, but will refuse grain,
lose weight, and soon drop in milk produc-
tion. Changing of pasture gradually, by
feeding 1 to 2 kg. of hay before turning cows
out and locking them in the yard 2 to 3 hours
before milking, should help to encourage
normal grain consumption. The hours on
pasture can be gradually increased over 2 to
3 weeks as cows adjust to the new feeding
program.
Low fat test problems associated with spr-
ing pasture are caused by two factors. Low
fibre intake from this very lush, immature
forage results in less cud chewing and
reduces the amounts of buffering saliva pro-
duced by the cow. The resulting increase in
rumen acidity causes a change in the rumen
microbes which leads to a lower fat test and
more digestive upsets. Rapidly growing
grasses are also very high in potassium
which reduces the availability of
magnesium, a mineral which is essential for
butterfat production. Because of these two
considerations, it may be helpful to add up
to 10 kg. of sodium bicarbonate and up to 5
kg. of magnesium oxide per tonne of grain
ration or equivalent of commercial buffers
to all grain fed during the first 4 and 5 weeks
of the pasture season.
The quality of pasture torage cnanges
quite dramatically over the summer. Grass
pastures which are 15 to 16 per cent protein
and 60 to 64 per cent T.D.N. in spring will
decrease to 10 to 12 per cent protein and 55
per cent T.D.N. by late June under good
rotational grazing.lf older grasses are
allowed to go to seed, this forage may be as
low as 7 to 8 per cent protein and 50 per cent
T.D.N. on a dry matter basis. Where
legumes make up a major part of the
forage, changes will be less dramatic with
protein declining from about 17 to 12 per
cent and T.D.N. from 62 to 55 per cent under
good pasture management.
The grain ration should be reformulated
in spring and again in late June to reflect
these changes in forage quality. Some sug-
gested grain mixes for cows on pasture are
provided on the following page.
Later in the summer, particularly during
perm.. of tent dry weather, both the quality
and quantity of pasture will be surprisingly
poor. Because of this, It is reconunended
that pastured cows be supplemented with 1
to 2 kg. of bay per day on an ongoing basis.
When cows clean un this hav ouickly it is a
sign that pasture is not providing the need-
ed nutrients, and the feeding of extra hay or
silage is required.
It should also be noted that trials in
Wisconsin comparing various methods of
harvesting forage crops show that the same
hectare of forage will result in a consump-
tion by cows of 1.9 tonnes of dry matter per
problems
year from continuous grazing, 3.8 tonnes
from pasture rotation, 4.8 tonnes from strip
grazing, 6.9 tonnes from green chopping or,
8 tonnes from harvesting at the ideal stage
of maturity and feeding from storage. In
view of this, pasture may not be an
economical use for high priced land. Never-
theless, it remains a convenient and
economical way to feed cattle on marginal
land during the summer months. With good
pasture management and the required ad-
justments in the grain ration, it will be
possible to maintain high production with a
pasture Program.

- Cows producing over 25 kg. of milk/day re-
quire 1 to 3 kg. of soybean meal topdressed
daily according to production, on the spring
rations only.
- Grain feeding levels on summer rations
should be 20 per cent higher to adjust for
lower T.D.N. in forage.
- When commercial protein supplements are
used salt and mineral recommendations
should be altered according to amounts sup-
plied by the supplement.
Farmers to be questionned in farm survey
How many acres are seeded to wheat or
corn this year? Are hog numbers on farms
continuing to increase? How have farm
operating costs changed since the previous
year?
The answers to these and similar ques-
tions will be provided by Statistics Canada's
annual National Farm Survey. This year the
survey will be conducted between May 26
and July 12. Approximately 44,000 farms
will be contacted by mail, telephone or per-
sonal interview.
The survey will be carried out in two
stages; some farmers will be contacted in
late May and early June so estimates of
crop acreage can be published soon after
seeding is completed. Later in June and in
early July interviewers will be contacting
farmers to get livestock numbers and farm
expense information.

Data derived from this survey are used
extensively .by individuals and organiza-
tions associated with agriculture at the pro-
vincial and national levels. Formers use the
aggregated data directly to make produc-
tion and marketing decisions. The federal
and provincial departments of agriculture
use the data for market analysis and
agricultural outlook reports which are then
provided to farmers through agricultural
organizations and the farm media.
Governments use the information to
negotiate international sales and trade
agreements and to 'assess the need for
agriculture policies and programs at both
the national and regional levels.
Only about 15 per cent of the farms in
Canada are surveyed. However, the co-
operation of each farmer is essential to ob-
tain good estimates for the total agricultural
sector.
