Beef Cattle Winter Feeding
Winter Feeding Strategy
You may be faced with feeding less feed or feed of a poorer
quality, yet your cattle still need adequate amounts of energy, protein,
minerals, vitamins and roughage. Get a handle on available feed supplies for
winter feeding-quality as well as quantity. If there isn't sufficient feed for
the numbers of animals you usually over winter, then you have to decide whether
to buy feed or reduce the number of animals over wintered.
Prioritize herd reduction. Top keeping priority should be the
pregnant brood cows. If you can get them through the winter with enough body
condition after calving to rebreed on schedule, your breeding program won't
suffer too badly. That will help you win the war even if you feel you are
currently losing the battle.
Pregnancy check the herd in the fall. Cull the opens, cull the
bad feet, udders, eyes and personalities. Cull the poor mothers. Here's where
good records will help you. You can't always eyeball a loser or remember a
problem from last spring. If there is extra feed after the main herd's needs are
met, keep the best replacement heifers. Keep the bred heifers and if there's
enough feed keep heifer calves from your best cows. Use your records.

How well cattle tolerate the winter depends on their condition
at winter's onset. Thin cattle do not have fat reserves and need as much energy
as during any normal winter. They are also more likely to have low vitamin and
mineral reserves. Watch them closely for deficiencies, particularly vitamin A
deficiency. Separate young and thin cows from the rest of the herd. Feed the
young and thin cows extra forage or grain. Mature cows that finish the grazing
season in better than average condition can withstand some feed cutbacks. You
can reduce the roughage they receive from the 10 to 20 pounds you normally would
feed daily to a minimum of four to five pounds daily, along with adequate grain.
Greater reductions of forage would interfere with normal rumen function. During
the winter feeding these cows can lose up to 120 pounds. After calving give them
extra feed so they nurse properly and return to breeding condition. Larger
weight losses may jeopardize their health or cause breeding problems.
If you have to buy feed, decide whether you need hay or can
stretch existing roughage with grain or protein supplement. Poor quality
roughages if properly supplemented to meet the animals' requirements can replace
quality hay in maintaining the pregnant beef cow.
Thin cattle require more feed to keep warm. A thin cow can
require 50 to 70 per cent more feed during a cold snap than a cow with some fat
cover. That's why it pays to have cows come into winter in good condition - they
need less feed.
Don't waste feed. Feeding on the ground can waste up to 50
percent of poor quality feed. Of all feeding gates tested, home-built
"tombstone" type feeders wasted the least feed. If you are feeding with an
electric wire keep it adjusted. Moving it a little twice daily is better than
once daily and having the animals reach too much feed.
Retain the best quality feed for young stock and nursing cows
after calving, because both milk production and growth demand extra nutrients.
Allow enough feed for nursing cows to provide twice their precalving energy and
protein needs. Save your best roughage for replacement calves, bred heifers and
cows after calving. Both milk production and growth demand extra nutrients.
Ammonization of chaff and straw increases energy and crude
protein content. If allowed free access to treated straw or chaff, cows will eat
more than they would untreated. Intake increases from about 12 - 14 pounds of
untreated to 18-22 pounds of treated. Grain required drops from 5-6 pounds per
day to about 2 pounds. Conversely, if grain is fed at 5-6 pounds per head,
intake of ammoniated material can be restricted and still maintain the animal in
good condition.
Healthy cattle use feed more efficiently. Treat for warbles
and lice in the fall. Re-treat for lice in mid winter. Make sure vitamins A, D,
and E are adequate either through the feed or injections every 60 days. Balance
rations with enough calcium, phosphorus and trace minerals, either mixed with
the feed or fed free choice. Know your feed quality and your animal's
requirements. Have your feeds analyzed. Discuss your situation with your Ag.
