A calve
Some do, most don't. It always depends on when they're bred that will coincide to when they will calve. Some cows may calve on a New Moon, some may calve when the moon is at it's first or last quarter, or some may calve in between any of these times.
Cows are not plants, they are animals, which are capable of growing in any and all seasons.
I would spell this "calf" muscle - the plural is calves, but the singular is calf (in fact, calfs is coming into common usage in agriculture.) The large muscles at the top of the calf are the gastrocmenius, the muscles that extend the foot. The soleus are the flat, broader muscles that are underneath the gastrocnemius.
Some homophones for "lessen" include lesson, lessen, and leson.
