The timing of almost everything in commercial sheep and cattle enterprises is determined by the seasons and matching feed demand with feed supply. The most important decision of any breeding operation is when to calve or lamb. This then determines when to join females to sires for mating and will influence when the progeny is ready to be sold. The right timing will vary from region to region based on pasture growth patterns through the year due to temperature and rainfall. The AuctionsPlus Insights team has analysed throughput data for certain commercial cattle categories on AuctionsPlus to highlight the influence of seasonality on supply.
