Breeding and Reproduction of the Irish Dexter
Breeders are encouraged to establish a pure bred program in order to perpetuate this rare breed of cattle. In order for any animal to be registered with the American Dexter Cattle Association, both parents must be from registered Dexter stock. Crossbred cattle are not eligible for registration.
Irish Dexters are known for their ease of calving and their mothering instincts. Breeding longevity is very good. Many cows are calving as late as age 14 to 18 years. However, consideration should be given to the lower levels of colostrum in older cows, as with any breed, and adjust the timing of vaccinations as needed. Dexter heifers can be bred at 14 months so that the calf is born as the heifer turns two years of age. The ideal time for breeding depends on local climate. In a moderate climate, April is probably the ideal month, due to the longevity of nutrition available from summer and winter grass forages for the pregnant heifer or cow. As with other cattle breeds, a heifer will be more productive throughout her breeding life if she is first bred young.
A Dexter bull may be bred to another breed to produce a quality cross for commercial purposes. In fact, a first time heifer of another breed is often bred to a Dexter bull to help in ease of calving by producing a smaller offspring.
