It is acknowledged that good pasture growth can be attributed to good management, but there are also are number of factors to be taken into consideration that are beyond the control of the farmer. These main factors include rainfall and temperature. Ensuring that the entire dietary requirements of the cow are met is paramount to optimising milk production and hence, profitability. Therefore, it is vital that dairy farmers become increasingly proactive in minimising the uncertainties in pasture growth and availability and become more focused on producing forages that can be preserved and utilised when pasture is.
