Milk production is the lowest in five years at the Macalister Demonstration Farm. The feed margin is the lowest in four years. Hectares being used, and cows being milked, are similar. Amount and type of supplements being fed is similar. So, the main reason for the lower milk and profitability is less grass being consumed, as shown by the table of calculations, and graphs. Grass is nearly always the dominant driver of milk and money.
Fertiliser application is similar to other years. The grazing rotation (possibly a bit short for now) is similar to most years. Some paddocks have been resown with crops, the crops growing well but probably not making up for the lost growing time, before and after the crop.
The problem seems to be a wet year. It saves irrigation, but wet soils lose or waste nutrient, cause more pugging and therefore weed invasion, and make grass utilisation more difficult. Good drainage is a powerful tool.
A grass residue build-up at wet/muddy grazings makes it even more difficult to get high utilisation at later grazings, a compounding problem. The cows could be forced to fix the residue, but they will graze some patches far too hard, and milk is lost in the short and long term. An unavoidable residue-build up is best fixed by topping to an even and appropriate height.
