Department of Dairy Husbandry
It shall be the purpose of this bulletin to present data which will answer the question as to the advisability of using as foundation stock the animals already on the average farm, and also to indicate the increase in production of the progeny of good purebred sires, assuming that the cows are fed properly. The data will furthermore throw some light on the question whether a farmer should raise his own cows or buy them. If as good cows can be raised in a comparatively short time, it seems rather hazardous for the average prospective dairyman to risk buying cows because of the danger of introducing disease into the herd. The dairy business, like any other, requires experience to learn and in too many instances this is obtained at the expense of high priced dairy animals. Often the results are discouraging and the entire blame is put on the dairy cow. This may lead to the discontinuance of the dairy and discourage others who contemplate entering the field. It is paramount that dairymen should understand and practice the best methods in feeding and management in order to meet with success. It matters not how well bred an animal is, or how great her tendency for high production, she must be fed a ration which furnishes sufficient nutrients if she is to produce at her maximum, or even produce milk efficiently.
