Tips on winter livestock management

Rain, sleet, snow, ice, freezing temperatures—winter can be a real struggle for two- or four-legged animals. Those of us with two legs can generally put on a warmer coat or go inside to warm up with a cup of something hot, but what can livestock managers do to keep animals healthy and comfortable in winter?

Water: The necessity of a clean and reliable year-round source of water cannot be overemphasized. Novice managers often mistakenly believe that animals can meet water requirements by eating snow or licking ice. With daily water requirements varying from three gallons (sheep) to 14 gallons (cattle), one can see that livestock would need to spend every waking hour eating snow to meet their requirements. Ice and snow consumption also lowers body temperature and increases maintenance energy needs, so it should be discouraged.

 Water consumption is encouraged when water temperature is 37 degrees or above. Tank heaters may be required to ensure that water sources do not freeze. Be sure to follow manufacturers’ recommendations to prevent fires and electric shocks or electrocution of livestock. If heaters are not used, unfrozen water should be provided several times a day. Ensuring adequate water intake will encourage optimal health and performance of livestock and help prevent serious conditions such as colic and impaction.

Energy Requirements: Livestock’s maintenance nutritional requirements can increase significantly during cold weather. Requirements increase dramatically if animals become wet and/or there is appreciable wind. Lowest critical environmental temperatures (LCT) for livestock vary according to species and researchers, but 20 or 32 degrees are often used as the lowest temperature dry livestock can tolerate without additional energy demands to support normal body temperature. Some researchers state the LCT for wet animals is 60 degrees. Energy requirements for an animal with a healthy and dry winter coat increase by one percent for every degree the wind chill temperature falls below the LCT. Energy requirements for an animal with a wet coat increase by two percent for every degree drop in the wind chill temperature.

Energy can be provided through grain or additional roughage (hay). Roughage is generally preferable due to its feeding safety, lower cost and greater heat released during digestion. However, roughage is in short supply in most areas this winter, so grain (corn, barley, wheat, oats, etc.) may be more accessible and affordable. Frequent small grain feedings are safer than one large daily feeding. Grain supplementation rates will vary with species, so discuss feeding rates with your Extension agent. 

Some cold and wet weather fronts can result in predictions that livestock will need close to a 100-percent increase in energy requirements to help them maintain normal body temperature and functions, but such a large, sudden and short-term increase in energy intake is not healthy for most animals. All dietary changes, be they increases or decreases, should be made gradually. Although dietary energy increases are necessary during inclement weather, livestock will fare better if they have sufficient body condition to call upon during times of need. Blankets can be used daily or as needed to retain body heat for individual animals. This technique is most common for elderly or “hard-keeping” horses or the occasional pet goat. The portion of the blanket closest to the animal should not become wet.

Feeding: Labor availability is often a major factor in determining how and how often animals are fed in winter. With daily hand feeding, managers will have a better sense of individual animal’s health and appetite, but hand feeding is labor intensive. Feeding big bales to a group of animals once a day or even less often saves labor, but individual animal health can be overlooked. Animals fed directly on the ground will often waste 50 percent of their hay, as will animals that are fed more than they can consume at one feeding.

Whatever feeding method is employed, managers must be sure there is adequate bunk or head space so every animal has the opportunity to eat its share of the ration. Dividing animals into groups based on nutritional requirements and feeding groups appropriately will make correct feeding more likely. Pregnant immature animals are an important group to feed separately. Pregnant heifers, doelings, etc. must maintain themselves, finish growing and grow a fetus. Failing to meet their nutritional needs may result in stunted animals, poor milk production and weak or dead fetuses. Don’t overlook minerals in the winter. Keep trace mineralized salt available at all times and try to protect it from the elements. Although horses and cattle do well with salt blocks, salt crumbles are best for sheep and goats.

Shelter: Shelter is another obvious winter livestock management concern. Animals do not necessarily need or want to live in an enclosed barn every day in the winter and barns for shelter are not practical for large herds of animals such as beef cattle. As discussed above, livestock can tolerate cold weather if fed properly for it. However, protection from wind and rain will decrease energy requirements and feed costs and increase animal comfort. Three-sided sheds, hills, thickets of trees and solid or semisolid fences can all serve as adequate breaks from the prevailing winds. There must be sufficient space for all animals to benefit or overcrowding and even trampling can occur. If animals do not have enough space and variety of landscape to select a spot protected from the elements, a shelter should be provided. Shelter requirements vary between species—sheep with thick fleeces will graze and spend a great deal of time outside during poor weather, but most goats prefer to stay dry than eat.

If a structure is provided, be sure to keep the bedding dry and as clean as possible. Bedding helps insulate animals from the cold ground. However, in bedding soiled with animal wastes, ammonia fumes can build up quickly in the lower 18 inches where recumbent animals breathe; irritated respiratory lining is then very susceptible to pneumonia causing bacteria and viruses. Provide good ventilation so the air seems fresh, but do not permit drafts in the structure. Again, prevent overcrowding and make sure there is enough space for all animals.
