Shearing contributes to the overall health of the sheep

Drier environment. Wool holds considerable moisture, with a full fleece capable of absorbing a lot of water under humid climates, even when sheep are housed indoors. This moisture holding capacity of wool creates a microclimate close to the lamb that is relatively damp, thus creating a prime environment for hosting pathogens and allowing them to proliferate. Both the relative humidity of the barn and the microclimate near the lamb are drier when ewes are shorn, creating a healthier environment that is less conducive to pathogen growth
