Feed Bunk Management

The bunk tells you more about your cattle than almost any other spot on the place. Learning to read it, and to feed on a steady routine, prevents digestive trouble and wasted feed.

Key points

Feed at the same time every day and check what is left.
Give every animal room to eat and sort groups by size.
Clean out spoiled feed and change rations gradually.
Watch behavior and call the vet for sick animals.

Why bunk management matters

Cattle are creatures of habit. When feed shows up at the same time in the same amount, they eat in a steady pattern and their rumens stay settled. When feeding is erratic, they gorge after a long wait or pick through the ration, and digestive upsets follow.

Good bunk management means delivering the right feed, in the right amount, at a regular time, and then checking what is left. It takes a few minutes a day and pays back in healthier cattle and less waste.

Keep notes for a few weeks on what cattle leave and when. Patterns appear quickly, and they tell you whether the problem is the feed, the schedule or the cattle themselves.

Bunk space and access

Every animal needs a place to eat, and the shy or small ones need it most. Crowded bunks let boss cattle push others away, which leads to uneven intake and uneven growth. Ask your extension office or nutritionist what space per head suits your class of cattle and your feeding style.

Keep the approach to the bunk free of mud, ice and obstacles. Make sure the bunk surface is clean and sound, with no sharp edges or loose boards, and keep the area drained so cattle are not standing in a mess.

Reading the bunk

Reading the bunk means looking at what is left before you feed again. Some operators use a scoring system, giving a number to the amount of feed remaining in the bunk each morning. Ask your nutritionist to show you a method that fits your setup, then use it the same way every day.

Empty bunks and heavy leftovers both tell a story. A bunk licked clean may mean cattle are hungry or underfed. Feed piling up may mean they are off feed, the ration changed, the weather turned or someone is sick. Pay attention to trends, not just a single morning.

Make sure the person reading the bunk is the same each day if possible. Consistent eyes catch small changes before they become problems, and a short written note passes the information to whoever feeds next.

Cleaning and feed freshness

Old, wet or moldy feed in the bunk can put cattle off their feed and cause digestive trouble. Clean out leftovers regularly, especially in warm or wet weather, and do not shovel spoiled feed back into the ration. Keep records of when and how much you remove.

Store feed so it stays dry and clean. Cover commodities, protect silage and baleage, and keep rodents and birds away. Dusty or heated feed should be checked with your nutritionist before feeding.

Water troughs near the bunk need the same attention. Dirty water cuts intake as surely as spoiled feed does.

Changing rations and feeding amounts

Cattle need time to adjust when feed changes. Increase amounts and change ingredients gradually, following a plan from your nutritionist. Sudden changes can cause digestive upset, including acidosis in cattle on higher-grain rations.

Do not try to make up for a missed feeding by putting out a giant load. Return to the schedule and consult your nutritionist if you are unsure how to restart.

Mixing order and mixing time affect how even the ration is. Ask your nutritionist how to load and mix your equipment, and watch for cattle that sort out the fine parts and leave the rest.

Watching animal behavior and health

Watch cattle at feeding time. Some will rush the bunk, some will stand back, and some will not come at all. The ones that stay away deserve a closer look. Signs such as dull eyes, droopy ears, loose manure, drooling or a hollow flank can point to sickness.

Call your veterinarian if you see sick animals, and do not treat on your own. Any treated animal has a withdrawal time for meat set by the label or your vet, and following it exactly protects the beef supply. Keep treatment records.

Weather matters as well. Cattle eat differently in heat, cold, wind and mud, and a good manager adjusts amounts and timing in line with advice rather than sticking to a fixed number.

Common mistakes and safety

Common mistakes include irregular feeding times, overcrowded bunks, ignoring leftovers, and changing rations too fast. Another is failing to calibrate scales and mixers, so the amount delivered is not the amount you think.

Safety matters at the bunk. Feed trucks, tractors and loaders are dangerous, and cattle can crowd or bolt. Follow manufacturer, OSHA and extension guidance, keep children out of feeding areas and stay alert around moving equipment.

Calibrate scales and mixers regularly
Keep visitors and children away from equipment
Use the same feeding routine every day

When to get help: Ask your nutritionist or extension specialist to help you set up bunk scoring and a feeding schedule, and call your veterinarian about cattle that stand off feed or look sick.
