Breeding
Ken started calving on 29th July and finished on 6th September, which gave him a calving spread of 5.5 weeks. 67 calves are alive on the farm at present and there were no sets of twins. Four calves died at birth/just after due to weak calves, one early arrival and another getting stuck at the hips. One cow is suspected of killing a calf. Another calf had an internal issue and passed away after veterinary treatment. This left Ken with 6 dead calves and an overall mortality rate of 8%.
Breeding will be starting on 26th October and will continue for 6 weeks until around 7th December. Ken has picked AI bulls to suit his breeding females, i.e. the heifers to calve at 24 months will be bred to easy calving Angus bulls such as AA4089 and ZEP, the high Eurostar, milky and docile cows will be bred to maternal bulls like SI4147, SI2152, AU4460, AU6918, LM4302 and LM2190and the rest of the cows will be bred to terminal bulls like AA4087, ZFL, AA4303, AA4840, LM4302, LM2190. Any cows/heifers that repeat will get short gestation bulls to help keep his calving spread tight. They will be housed for breeding as Ken finds it easier for heat detection and for serving cows that way.
Ten cows were selected for culling already that have lost calves, had mastitis, age and temperament. That will leave about 63 cows for breeding. Allowing for 90% going in calf, there will be 56/57 cows. 15 heifers are suitable for breeding and assuming that 13 of these will hold in calf, there should be around 70 cows in calf at the end of the breeding season. Due to an extra 2 cows losing calves, Ken has picked 5 extra heifers to breed to keep his numbers up.
The heifers selected are over €120 on the Eurostar index (herd average is €116), were over 320kg on 15th June (to gain 100kg by early October and be a minimum of 420kg in early October). They are preferably genotyped and preferably have >5kg milk with a negative calving interval. They will be bred to an easy calving Angus bull so that the calves will be polled. AA4089 will be used on some of these. He is 3.9% for heifer calving difficulty with 99% reliability. Carcass weight is okay at 8.7kg and he has a carcass conformation of 0.79. His replacement figures are good as well so good performing heifer calves could make potential replacements. The remainder will be bred to ZEP who is 3.5% for heifer calving difficulty at 97% reliability, has a carcass weight of 6.1kg and a carcass conformation of 1.02. His heifers would also make potential replacements.
