Normal Growth of the Jersey Cow

Department of Dairy Husbandry, University of Missouri, Columbia, Missouri

ABSTRACT

The normal birth weight of Jersey males and females and the normal growth of the heifers until two years of age has been determined at this station, by Eckles (1, 2). It is well known by dairymen, however, that growth continues for several years. As dairy cattle are bred to calve at approximately two years, the lactation (3) following seriously interferes with normal growth after that age. Still lactation is a normal function of the dairy cow and it is of considerable value to determine the normal growth with age of the lactating dairy cow.

For the past twenty years the American Jersey Cattle Club has required that the weights of all cows completing a Register of Merit record be reported. The object of this paper is to report the results of a study of this data based on the weights of 15680 animals at various ages throughout the entire productive life of the dairy cow.
