Bison are seasonal producers (unlike cattle and sheep which can breed any month of the year) and go into a breeding season, called rutting, in mid-summer that usually ends around August. Any cows that do not get pregnant but are in good body condition can remain fertile into the early fall, so that sometimes we get calves born the following fall instead of spring like normal. Spring is nature's regular cycle for calves to be born as that is when the grass is plentiful for cows to produce milk. Bison are much like deer and elk in their natural breeding and feeding cycles. Bison produce a small quantity of milk that is very thick, rich and sticky compared with cattle milk. It is impossible to milk bison due to the danger and stress on the cow and the quantity of milk produced makes this uneconomical to even consider. Buffalo mozzarella is made from water buffalo, but not bison.
Big Horn Bison is currently growing our herds. For this reason, our herds are not up for auction at this time. Bison take longer to get to market. Big Horn Bison anticipates two to three years before our bison herds are large enough to legally and ethically disperse.
