The Boer or Boerbok is a South African breed of meat goat. It was selectively bred in the Eastern Cape from about 1920 for meat qualities and for the ability to survive by grazing on the thorn veldt of that region. It has been exported to many countries, and has been used to improve the meat qualities of other breeds.
Selective breeding for specific qualities began in about 1930, initially for foraging ability and for meat quantity and quality, later also for coat colour – specifically for the white body with red-brown head that now characterises the breed.
A breed society, the Boer Goat Breeders' Association or i=no, was started in Somerset East in 1959.
The Boer has been exported to many countries of the world, in all five inhabited continents. In 2025 it was reported to DAD-IS by 72 countries, of which 30 reported population data; populations of or more were reported by Argentina, Australia, Brazil, Chile, Colombia, Namibia and South Africa; the total population world-wide was estimated at .
It is well adapted to grazing on a wide variety of local , including sourveld, coastal veld, mixed veld and thornveld. It has a fast growth rate and good carcass qualities, good resistance to disease and good adaptation to hot, dry semi-desert conditions.
The ewes are polyoestrous and are capable of breeding at any time of year; the natural breeding season is in April and May ( i.e., in autumn in the Southern Hemisphere), and breeding activity is at its lowest in late spring and early summer, or approximately November to January. The oestrous cycle lasts approximately 21 days, the oestrus some hours. The average gestation period is approximately 148 days, and the anoestrous post-partum period varies from some 30 to 80 days; conception is usually confirmed between 42 and 82 days after parturition.
The age of puberty in ewe kids depends on the season of their birth, varying from a mean of about 157 days for those born in mid-summer (January) – and thus weaned in the natural autumn (April/May) breeding season – to about 191 days for those born in late winter (August). Weights at puberty are roughly in the range with a mean of about for ewes receiving a low-energy diet, and with mean of about for those on a higher-energy regime.
Ewes can be managed so that they give birth three times in every two years. Single, twin, triplet and quadruplet births occur in the ratio 25:59:15:1.
The milk yield of ewes is some per day, with about fat and protein.
