Occurrence of Multiple Hemoglobins in Certain Breeds of Dairy Cattle¹

Depts. of Agricultural Chemistry and Dairy, Michigan State University, East Lansing

ABSTRACT

An investigation was conducted to determine whether multiple adult hemoglobins occur normally in dairy cattle. Hemoglobin preparations from 158 animals were examined by paper electrophoresis.

All the Holsteins, Brown Swiss, and Ayrshires examined possessed a single component, designated Hemoglobin A. It was concluded that the possession of Hemoglobin A alone is characteristic of Holsteins. On the other hand, a second, faster-migrating component, called Hemoglobin F, was found in the blood of 15 of 34 Guernseys and 17 of 25 Jerseys. Nineteen Guernseys and eight Jerseys had Hemoglobin A only, and two Guernseys and four Jerseys had Hemoglobin F alone. In all blood samples containing both types, the ratio of Hemoglobin A to Hemoglobin F was close to 1:1. The occurrence of Hemoglobin F in some adult dairy animals appears to be a normal, breed-specific phenomenon.
