Health advantages of calf warmers

It’s not always possible to be born and on a warm, sunny day and it seems more often than not that the weather is at its worst when your calf arrives. A warmer provides a secure and comfortable enclosure to foster a nurturing environment and allows for the quickest possible recovery after what can be a very traumatic birthing process. Leaving its comfortable and toasty mother and being thrown directly into the often cold, wet and windy conditions, a newborn is immediately exposed to a dangerous and life-threatening environment while they are so fragile.  It can be such a dramatic shock that your animal may experience long-term health problems or even death from extreme exposure at such an early point in its life. Immediately protecting your animals from the elements is never more important than when they are in such a vulnerable state.

Heating Controls in calf warmers:

Don’t let your little ones freeze in the pasture, keep them warm for the best recovery possible.
