The best quality and best fit calf and goat cover you can find!

Calves are born with only 3% body fat and a high surface area to body weight ratio. Under 3 weeks of age they should be fed extra milk to counteract the energy they lose through maintaining body temperature when exposed to temperatures less the 15°C (lower critical temperature).  By using the a long-lasting Thermoo calf cover your calf can divert available energy to more effective needs such as feeding, building immunity, and growth. 

It has been proven that below 10 degrees Celsius (50 degrees Fahrenheit) ambient temperature, the rate of colostral antibody absorption in newborns decreases (Olsen et al, 1981). By maintaining calf warmth you can ensure that your calves receive maximum benefit from the colostrum you have carefully supplied.

At 10°C the calf requires and extra 0.5 L milk per day, at 5°C an extra litre and at 0°C an extra 1.5 litres.

The Thermoo calf jacket has been specially designed for calves and has unique features making it highly practical and long-lasting.
