SCIENCE OF MILK PRODUCTION

"Condenses a vast amount of scientific data into a simple and easily understood account of the cow's function as a 'milk factory.' It was produced with the cooperation of Professor Leland Peterson, nationally-known authority on dairy husbandry at the University of Minnesota, whose studies of and experiments with the milk cow form the basis of much of the film's content." "The film shows that the productive life of a cow is in four periods—dry cow, calf, growing heifer, and milk cow. The correct diet for the cow is stressed, and the importance of the milking machine is explained and demonstrated." Educational screen.
