Trisha Cowley & Whitney Dollemore, Livestock Industry Development, Katherine Reproductive performance is a key profit driver in northern Australia, with plenty of room for improvement. While nutritional management is key, genetics also definitely play a major role. The Beef CRC III research program found that the heifer fertility traits, age at puberty, and time to resume cycling after calving were highly heritable in Brahmans and Tropical Composites. Furthermore, these two traits were strongly genetically correlated to lifetime reproductive performance, meaning that heifers who reached puberty at a younger age and reconceived earlier after their first calf, tended to have more calves in their lifetime. Hence by selecting superior heifers for these traits, you are also selecting those who will be superior breeders over their lifetime. Sires have the largest influence on the genetic direction of a herd, so selecting superior sires is also critical. Show them what your daddy gave you!
