Not every farmer or dairyman can qualify as an expert judge of cows, but every herd owner can pick high and profitable producers by sticking to certain principles. It’s a matter of pedigree, production and type or form. But only an estimated one out of every 20 dairy cows is purebred and registered, with a pedigree. The number of cows on which there are production records is only slightly larger than that. Hence most dairymen and farmers choose a cow on looks alone, that is, on her type and form at certain key points of the body.
