Research trials at North Dakota State University indicate young calves may benefit from wearing a wool-polyester blend blanket during cold winter months.

During the trial period, calves wore either a wool-polyester blanket from birth to three or four weeks of age or did not wear a blanket. Blanketed calves gained an average of 0.22 more pounds per day and were less sick than calves not wearing the blankets.

The results indicate calf blankets may be most beneficial for use on calves that are less than four weeks old during the coldest winter months.
