A Study of the Relation Between Feed Consumption and Milk Secretion

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

ABSTRACT

While many yearly milk production records are available which permit the study of the normal course of milk secretion during the lactation period, records of feed consumption during the course of the lactation period are very limited in number. Studies showing the relation between total feed consumption and total milk production are the basis of the modern feeding standards for dairy cattle, but the relation between feed consumption and milk secretion during the course of the lactation period has not been determined.

Study (1) of the characteristics of the yearly milk secretion curves of the various breeds of dairy cattle and a number of groups of cows within certain breeds indicate that under favorable conditions of feeding and management the factors controlling the rate of increase in milk secretion during the early part of the lactation period and the rate of decline following the period of maximum production appear to be inherited characteristics governing the mechanism of milk secretion.
