Data from 2, 056 inseminations of 902 Red Danish heifers were used to study the relationship between service interval and interval from first service to conception, number of services per conception and butterfat yield. Analysis of the data indicated that there was no biological relationship between the butterfat yield and the number of services required per conception.
