Random thoughts #??

Hi there. This post is just about me and the weird thing I'm curious of:

What will happen if sheep is not sheared? 
Will they feel hot in summer? 

Just in case there's someone out there who is as concern as I am with the sheep's comfort, here's the answer: 

Heat tolerance

Some livestock (and people) tolerate heat better than others.  Sheep and goats tend to be less susceptible to heat stress than swine, cattle, llamas, and alpacas. Hair sheep usually tolerate heat better than wooled sheep.  This is why they are often used for training and trialing herding dogs. Fat-tailed sheep are also more heat tolerant. The European sheep breeds are usually the least heat-adaptive because they tend to have shorter bodies and legs, short, thick ears, tight skin, and dense fleeces.

Goats tend to tolerate heat better than sheep.  Goats with loose skin and floppy ears may be more heat tolerant than other goats. Angora goats have a decreased ability to respond to heat stress as compared to sheep and other breeds of goats.

Dark-colored animals are more susceptible to heat stress, while light-colored animals may be prone to sunburn. Females usually handle heat better than males. The heat is especially hard on fat animals. Horned animals dissipate heat better than polled (or disbudded) animals.

Young animals are more susceptible to heat stress than older animals, though the geriatric animal is also very vulnerable.  In fact, any animal with a poor nutritional status or compromised immunity will be more susceptible to environmental extremes.

Wool

Wool protects sheep from extreme heat as well as extreme cold.  A thick fleece is mostly immune to temperature changes due to its insulating properties.  According to research, sheep with a one-inch fleece are more comfortable than sheep with less wool, as wool fibers dissipate heat more rapidly.

Woolly and hairy animals should be sheared prior to the onset of hot weather. Spring shearing allows sheep to have adequate wool growth to keep them cool in the summer (and avoid sunburning) and a full wool coat in the winter to keep them warm. Sheep and goats should not be sheared in extreme heat.

Shearing lambs will improve their growth performance (and welfare) during the summer months, if temperatures and humidity are elevated.

Apparently, some of them do.
Cheers! :)
