  • Another week has gone by, calving’s mostly done – the focus moves to getting ready for mating. Discussion at recent “Mating and M. bovis” workshops have focussed on using the pre-mating period to hone the teams heat detection skills so that everyone is ready for the start of mating. Early calving herds should be around a week into collecting pre-mating heat records – those calving later in July should have their herds tail-painted now and starting to record. Use one colour tail paint to start, then a second colour as cows cycle and their tail paint is removed.  At three weeks, cows with the original colour will be the non-cyclers. If less than 75% of the herd have had a recorded heat by 10 days before the planned start of mating, either heat detection methods have not been fully effective and/or there are a large number of non-cycling cows. This is the time to seek further advice and consider which options are available to improve heat detection during AB and seek vet advice on the most effective strategy to treat non-cycling cows. By the time the actual start of mating kicks off, 85% of the herd should have had a recorded heat. These are the relevant KPI’s if we want to hit the industry targets for reproductive performance. We are going to have to lift our game if reproductive performance is to be improved. The benefits are obvious and will be long term if calving can become more compact. Attention to detail will need to be the ‘catch cry’, and use of the pre-mating period to iron out any wrinkles in the approach to the mating period will pay dividends when mating starts.
