Thermoo Calf Blanket

Calves are born with only 3% body fat and a high surface area to body weight ratio. Under 3 weeks while reliant on milk they should be fed sufficient milk to counteract the energy they lose through maintaining body temperature under the lower critical temperature of 15°C.  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.

"I have opted for cheaper calf jackets in the past and we found the Thermoo far superior in design, material, quality and warmth.  The shape and fittings are ideal for a cosy, secure fit."
