Welcome to KDK Longhorns!

We are a family-owned, central Texas Longhorn breeder. Our goal is to develop a reputation as a high-quality breeder who is a fine steward of the Longhorn breed - who both promotes and preserves this historic breed. We breed for the complete longhorn - one whose horn length, base, and body are well balanced. It is extremely important to us to raise longhorns that are gentle, beautiful, happy, and healthy. We have an environment that is a natural one for a Texas Longhorn - they have free range over large acreage to forage on a wide variety of plants and grasses. We spend a lot of time around our herd so that they are used to people, dogs, and vehicles. While the breed is naturally gentle, we find that the more time we spend with them, the easier they are to work and for our visitors to view them up close. Our herd can be easily penned and are content to have our five dogs in close proximity. We take herd health very seriously - all our cattle are regularly dewormed, have access to mineral tubs at all times, and are up to date on vaccinations.
We have assembled our herd from various elite breeders, by purchasing cattle at prominent Longhorn auctions in the Texas/Oklahoma area, and visiting ranches to make private treaty purchases. After spending several years building our herd, we are finally able to offer some of our cattle for sale. We offer a range of price points and are happy to help new breeders. We price our cattle based on pedigree, horn length, color, and body. Prices are subject to change without notice based on the market, inventory, and new horn measurements. Please take a few minutes to browse our animals. We hope you enjoy them as much as we do!

We welcome new and experienced breeders to visit our ranch in Llano Texas, see our herd, and talk Longhorns!
