Unshaven animals often get too hot in the young cattle shed. Young stock, heifers and calves have a long and very dense winter coat. They don't need that coat in the young cattle shed. The winter coat makes them sweat very quickly.
In summer we regularly see an inflammation of the eyelids and/or the cornea in young stock and cows (but also in small ruminants). This condition is called “Pinkeye”. It is usually caused by a bacterium (mainly Moraxella bovis). The infection pressure varies greatly from region to region.
Cattle can tolerate the cold well, but the heat badly.
Heat stress occurs when an animal is no longer able to regulate its body temperature due to high temperatures and humidity.
Cattle like temperatures between -10 ° C and + 18 ° C. Higher than + 18 ° C is too warm.
