Gene
Dexter dun is a recessive change in TYRP1, the brown gene, that dilutes black hair to dark brown or gold, so a black-based Dexter with two copies is dun. One copy has no visible effect, and red hair is not diluted. It is unrelated to the dun color of Highland and Galloway cattle, which comes from PMEL dilution.
Cattle show Dexter Dun only with two copies. One copy makes a carrier, which looks normal but can pass Dexter Dun on.
A second recessive Dexter dilution, in SLC45A2, gives chocolate on black and cream on red and can look like dun; it is not in this catalog yet.

A cow costs more right now than at any point in history. In mid-2026, plan on roughly $2,500 to $3,500 for a commercial bred beef cow, $4,000 to $6,000 for a cow-calf pair, and $3,000 to $4,400 for a good dairy cow, with registered and top-end animals selling well above those ranges. Even a weaned […]
Feed cattle forage first. Cattle are ruminants, built to turn grass and other forages into meat and milk, so the base of nearly every beef diet is grazed pasture in the growing season and conserved forage (hay, silage, or baleage) through winter. Everything else, protein and energy supplements, minerals, and grain, exists to fill the […]
A cow is pregnant about 283 days (279 to 287). Our cow gestation chart turns a breeding date into an expected calving date, with breed differences.
A calf growth chart is a dated series of actual or clearly labeled estimated weights tied to one animal ID. It can reveal a trend and guide a conversation with a veterinarian or nutrition adviser, but it cannot diagnose why growth changed. Start a cattle profile, then record each measurement consistently. The cattle breed index […]
