Learn what Kunekune wattles (piri piri) are, how breed standards treat them, and why wattles alone do not prove purity or a specific function.

Kunekune wattles are one of the breed's most recognizable traits. They are fleshy appendages that hang from the lower jaw and are also called tassels or piri piri. Current registry standards treat wattles as a conformation/breed characteristic—not as proof by themselves that a pig is purebred. [1]

What Are Kunekune Wattles?

AKKPS terminology defines wattles, tassels, and piri piri as the fleshy appendages hanging from the lower jaw of many Kunekunes. A pig may have two, one, or no wattles. The AKKPS breed standard lists two well-formed, well-attached wattles as the desirable standard. [1] [2]

Do Wattles Have a Proven Function?

Current Kunekune breed standards describe wattles as a physical breed trait but do not assign a proven communication or temperature-regulation function to them. Claims that wattles serve those functions should therefore be treated as unproven rather than established facts.

Do Wattles Prove a Kunekune Is Purebred?

No. Wattles are useful when evaluating breed type, but wattles alone cannot establish ancestry. Pedigree records and the registration rules of the relevant registry are what document parentage. Registry policies also differ: AKKPS describes two wattles as desirable in its breed standard, while IKHR requires two obvious wattles at birth for official registration of pigs born after July 1, 2020. [2] [3]

How Are Wattles Inherited?

For practical breeding purposes, Kunekune wattles are generally treated as a dominant inherited trait. AKKPS explains the simple model this way: a wattled pig can carry either two copies of the dominant wattle allele or one dominant and one recessive allele, while an unwattled pig is expected to carry two recessive copies. That means two unwattled parents should produce unwattled offspring, while a wattled parent can produce either wattled or unwattled piglets depending on the genotype of both parents. [6]

The familiar Punnett-square probabilities are useful as litter-level expectations, not guarantees for a particular litter. For example, a heterozygous wattled pig bred to an unwattled pig is expected to produce about 50% wattled and 50% unwattled offspring over many births; two heterozygous wattled parents are expected to produce about 75% wattled and 25% unwattled offspring. Actual small litters can vary considerably from those percentages simply by chance. [6]

There is also molecular research specifically involving Kunekunes. A 2019 study presented at the European Symposium of Porcine Health Management examined 40 Kunekunes and additional Casertana pigs. In the genotyped animals, researchers found a strong genome-wide association signal on pig chromosome 1 in a region containing a bone morphogenetic protein (BMP) family gene and described it as the first mapping of the likely dominant wattle locus in pigs. That is important evidence that the visible trait has a real genetic basis, but it should not be overstated: the study mapped an associated region rather than establishing a definitive causative mutation or a commercial DNA test for Kunekune wattles. [7]

For breeders, the practical lesson is straightforward: use pedigree and actual offspring records to learn whether a wattled breeding animal is likely homozygous or heterozygous, and keep wattles in perspective. They are one inherited breed characteristic—not a substitute for sound structure, health, temperament, genetic diversity, and the overall purpose of a mating.

What If a Pig Has One or No Wattles?

That does not automatically tell you whether the pig is healthy, useful, or purebred. It does affect how the pig compares with a particular breed standard and, depending on the registry, may affect eligibility for registration. Always check the current registry rules rather than relying on appearance alone. [1] [3]

Care of the Wattle Area

Wattles normally require no special routine care. During ordinary health checks, look for cuts, swelling, discharge, or injuries around the jaw and neck just as you would inspect the ears, skin, feet, and other exposed areas. Contact a veterinarian if an injury is deep, infected, or does not heal normally.

Feeding and General Care Still Matter More

Wattles are a visible breed trait, but day-to-day health depends much more on balanced nutrition, clean water, appropriate shelter, exercise, hoof care, social opportunity, and preventive veterinary care. A complete pig ration should remain the nutritional foundation; forage and produce can supplement it. [4] [5]

Bottom Line

Kunekune wattles are distinctive piri piri that form part of the breed standard. They are not a proven cooling organ, communication organ, or stand-alone test of purity. Evaluate them as one conformation trait within the larger picture of pedigree, health, structure, temperament, and registry requirements.

In my own breeding decisions, I treat wattles as one visible trait, not as a shortcut for judging the whole pig. A pair of well-formed wattles can fit the breed standard, but I still have to look at pedigree, overall structure, temperament, health, and the purpose of the breeding program before deciding whether an animal belongs in it.
