Week ending farm notes

04 December

·        Cover has increased this week to 2369kgDM/ha with the whole farm growing 69kgDM/ha/day.  Cows have grazed 3.7ha/day this is equivalent to a 40 day round of the whole farm or 37day round of the paddocks held in the grazing round for the last week (137 ha). The large change in rotation occurred as we grazed off the very long silage paddocks. In the coming days we will return to approximately a 30-34 day round of the 137Ha in grass at approx. 4.5-4.0Ha/day.

·        With 70mm of rain in the second half of the week an increase in growth has occurred over last week, however the biggest change in cover comes from the small area of the farm grazed. 

·        The feed wedge  gives hints of a surplus several weeks out but we are considering the option to defer graze several of the silage paddocks (just eaten this week) for standing hay to manage this if necessary.  Brassica crops are looking fantastic after their drink of rain.

·       Milkers have been producing an average of 1.52 kgMS/cow this week ranging from 1.56kg/cow to 1.48kg/cow.  With the heat and the slightly poorer quality grass in the silage paddocks being the biggest influencer of production.  Cows frequently chose to cease grazing and seek shade in the hot weather that occurred – the visible effects of heat stress are difficult to miss at the moment.

·       Cows have been allocated 18kg of pasture this week though disappearance is closer to 17kg/cow/day as most of this week’s pasture was in very long silage paddocks.  Residuals in these paddocks was longer than target with a lot of stem left behind, however the tops of all seed/stem has been eaten and all available leaf well foraged. The regrowth is rapid and leafy from the base of the plant and we believe the remnant stem will be manageable by grazing early in the coming round and mown as a last resort.  PKE supplementation did not start in the past week, but will be introduced this week and cows will be offered 17kg of pasture/day
