Active Natural Service Herd Sires . . .
The following herd sires are currently in active use at Gibbs Farms as natural service herd sires. They may be found in a partners herd breeding cows in the spring or in collection at a bull stud during the off-season, but each can be found working in the pastures at Gibbs Farms in December and January. A Gibbs Farms herd sire is expected to work for a living, many of them traveling half way across the country twice a year, naturally servicing cows in fall and spring breeding programs as well as spending time in a bull stud building a bank of frozen semen in between their active pasture breeding jobs. Semen is available on most of these sires, either directly from Gibbs Farms or through one of the major bull studs.
