People who raise livestock often have questions about how to best care for their beloved animals in winter months. When readers came to us with their questions about how to best maintain animal health through the harsh winter months, we went straight to an expert: Dr John Mettler Jr, D. V.M. He has practiced as a large-animal country vet for more than 40 years in rural New York State and is the author of two animal books, and an expert in horse health. The answers below will help you decide on the proper cattle supplies, horse supplies and other winter equipment that will help you provide for your animals all winter long.

Q: A few years ago, I started keeping beef cattle, a milk cow, a few hogs, sheep and two horses on a farm in Vermont. Neighbors tell us that recent winters have been mild for this part of New England and that we're due for more normal weather with deep snow and below-zero temperatures in the coming months. Will this cause health problems, such as respiratory disease, in our livestock?  

A: If you maintained good livestock health during these past few milder New England winters, you'll do just fine when you have your animals in the snow. Still, Mother Nature shouldn't be underestimated: handling horses in the snow, proper cow care in cold weather and the necessary winter equipment are all situations worth preparing for before winter comes full force. It's important to know how to prevent weather-related winter health problems before they occur.

The two most important factors in livestock health are the effects, both internally and externally, of air and water: Both should be fresh and pure, and too much or too little of either will cause problems. All livestock suffer from the cold if they are wet. Cattle and horses, if given access to three-sided, shed-type livestock shelters open to the east or south, will stand under it during a cold rain, but will often be found outside, bedded down or feeding, on a cold clear night or day. Even with their backs covered with snow, the dry air trapped in their longhair coat insulates them from the cold (like the unmelted snow on the roof of a well-insulated house, it is an indication that the cow or horse is warm inside).

A tight but well-ventilated old cow barn that will stay above freezing if it is full of cows would not be the best place for a lone dairy cow. Perhaps you could rearrange things and keep your sheep and/or horses with her. Keep in mind that your dairy cow will get along fine in a cold, open shed (as does a beef cow), but milking at below-freezing temperatures is not particularly comfortable for the human part of the operation.

Hogs are okay in cold weather, but should be bedded heavily enough in their hog house so that they have a warm place to lie. After a really heavy snowstorm, you'll want to shovel a path from the hog house to the feed trough so that your hogs won't become snowbound.
