Chondrodysplasia Genetics in Mini Highland Cattle

Understanding the genetics of small stature is essential for any buyer or breeder. At MHC PTY LTD, we test 100% of our cattle for Chondrodysplasia (the dwarfism gene) and publish clear results on every animal's record.

✓ Tested Non-Carrier (Negative)True Natural Proportions

Naturally Small Miniature Genetics

Non-carrier cattle do NOT possess the chondrodysplasia gene. Their miniature height (34" to 42") has been achieved entirely through selective breeding over successive generations—mating small, sound bulls to small, sound cows.

100% Safe to Breed with Any Bull or Cow

Standard Leg-to-Body Skeletal Proportions

Zero Risk of Bulldog Calves in Any Pairing

Ideal For: Commercial and stud breeders planning to produce calves without requiring genetic pairing restrictions.

⚡ Chondro+ (Heterozygous Carrier)Ultra-Compact Legs

The Chondrodysplasia Gene (Dwarfism)

Chondro+ cattle carry one copy of the BD1 or BD2 gene. This produces exceptionally short legs, a wide head, and a deep body, often standing between 32" and 36" at maturity. They live normal, healthy, happy lives as companions or controlled breeders.

NEVER Breed Chondro+ to Another Chondro+ (25% Lethal Risk)

100% Safe when bred to a Tested Non-Carrier

Outstanding Paddock Pets & Lawn Mowers

Breeding Rule: If you purchase a Chondro+ heifer or cow, you must ONLY mate her to a certified Non-Carrier bull. We provide full DNA certificates at handover.
