It has made me a bit nervous, however (worrywart mom that I am.) If cattle eat too much fresh young growth, especially alfalfa and legumes, there is a risk of bloat, a life-threatening emergency. Our pasture is probably fairly low-risk, being mostly grasses with a small amount of clover mixed in, but I still worry.
In order to ease my mind, I make sure that the cows have eaten some hay before going to the pasture (both for the fiber and to reduce their appetite.) I wait until the dew has dried and I got them an anti-bloat mineral block. They seem to be adapting to the new diet very well.
studies of cattle whorls (the little swirl of hair on the forehead where the nap of the fur changes direction, creating a cowlick) that indicate that where the whorl occurs is correlated to the temperament of the animal. Cattle with the whorl above eye level, or no whorl at all were more easily agitated and those with whorl between the eyes or below eye level tended to be calmer. Lindy's distinct whorl is right between his eyes and his calm nature follows the rule.
Actually, all of our cows' whorls are between their eyes and they are all pretty mellow. But then, they really can't have much to complain about, pampered beasts!
