Why do cows bunch up

Insufficient ventilation causes more damage and problems than most dairy farmers know. Bad ventilation first of all makes that cows have to invest more energy into cooling themselves down, causing heat stress.

It also creates higher infection pressure for bacteria's and viruses, leading to more hoof problems and udder infection. Furthermore lack of fresh air leads to higher concentrates of ammonia, which you can expect to be less than ideal for animals. Farmers who want to improve their barn, should first have an expert!

This is the foundation. This also includes a plan with arrangements to manage heat stress. The independent experts of Vetvice can set up these plans for you: Nico Vreeburg vreeburg vetvice. Have you ever noticed this kind of huddling behaviour in summer, for example after a new construction changed the air flow?

Can you share interventions that you made that were successful no more huddling afterwards? Please share below, together we know more!

This is one of natural habites of herbivorous animal for safety. Alway walking and standing in one group. In case of summer huddeling for cooling and in sunlight area to huddling to reduce surface area to sunlight. Also mostly closed yard sustem cow huddling at side from new fresh air coming and to see something new like vehicle, others animal crossing or other road side. Very good question. I have seen in Scandinavia - and I always find pure ventilation in those barns. Ventilation is importend.

Right now I am in the States traveling. I have seen groups of beef cattle standing very close, and I was wondering why they stand so glose. I see two reasons: Naturally the cows will protect the calves born this year- they were standing in the middle of the group, - and next they were standing on a windy place- and the way the stand they also makes shadows fore the calves.

All are well ventilated but cows huddling occur in one shed whose direction is not according to the role. A serious out break of ring worms take place in winter and spread sporadically in the same shed. Always check the label for restrictions before using any insecticide or other fly control product. Bright light by itself will not cause cattle to bunch.

Rather, light avoidance is a secondary response to other stressors. Are some areas of the barn darker than others, and are cows bunching in the darkened areas?

Do cows still bunch after sundown? Answering these questions can help determine if cattle are displaying light avoidance behavior. Implement heat abatement strategies, control flies, and limit the variability in light intensity to prevent bunching in darker areas of the barn.

If cattle bunch in darker areas during the day, closing the curtains starting from the top down or adding shade cloth blinds on the brighter side of the barn may help. It may be necessary to angle shade cloth away from the sidewall, leave a gap at the bottom, or add additional fans to ensure adequate airspeed in the barn. Adding lighting to darker areas has also worked in some situations. If cattle still bunch in darker areas after sundown, clean light fixtures and consider adding additional lighting in darker areas to ensure that artificial lighting is evenly distributed.

Careful observation of cattle behavior can point toward solutions to cattle bunching. Implementing heat abatement strategies, providing plenty of fresh air and water, controlling fly populations, and reducing variation in light intensity can help to alleviate the problem. All bunched up. A combination of factors, including heat stress and flies, can cause cows to stand in groups.

Their herding instinct leads cows to bunch together as a reaction to stress, even in hot weather. HD Notebook. Ventilate the spots where cows need it most. Hoard's Dairyman Intel. We still make mistakes. Why is that cow standing? Animal Care. The lack of air flow from being so close together will often lessen the number of insects bothering them.

Cows will huddle around a new, suspicious item that they come across. Cows will check it out and then eventually move on if it is not food or water or of some other benefit.

Cows will stand in a circle for different reasons. If they have been fed grain or hay on the ground, cows will group in a circle to eat it, so they all get their turn. They will also stand in a circle when defending against a predator, but they will be facing outward, guarding any calves in the middle. Cows like to stand together by a fence because they are either waiting on food or waiting to find a way through.

If you regularly feed them close to a fence, cows will wait by that fence for you to arrive with their dinner. When cows are in barns, they often huddle together where they find the best air flow.

They may move in a group to different areas of the barn throughout the day, as the air flow changes. Cows eat together because they are herd animals, and they like to stay near each other. When grain or hay is fed, they know there is only a certain amount, so they will come eat at the same time.

Cows do not willingly share or save food for others, so they eat hay and grain together in groups, sometimes pushing one another out of the way to get their turn.
