However there are encouraging signs that the daily weather is changing......at long last!
Winter Damage to Pastures.
Most dairyfarm pastures have been damaged this winter by the extended cold & freezing temperatures. Cows appear to be grazing these fields really well despite the damaged plant tissue.
The big question is what damage has actually occurred?
There is a difference between winter damage & winter kill. Winter kill is where the meristem or growing point is killed by the freezing temperatures (ice rather than snow). The meristem or crown in ryegrass is very close to the ground & undamaged by grazing down to 1500 residual. It appears that this winter we have had pasture plant tissue damage & very little winter kill where the meristem has died. Most of the lower fertility grasses eg annual meadow grasses have been damaged & may explain why grazed pastures look so open. So very few ryegrass tillers have been lost.(Scott Laidlaw at AFBI Crossnacreevy agrees)
Once growth starts new tillers will be initiated..this is already happening. If we continue to get frosts this may effect the flowering of ryegrasses. Since 1997 at Aberystwyth Alan Lovatt tells me that the number of days to flowering have been reducing as we have had warm springs. So continued cold temperatures may possibly delay heading of ryegrasses.
Too early to say if pastures need additional ryegrasses....maybe clover will fill the gaps left by the killing off of the meadow grasses.
There is a marked difference on most farms between pasture that has been grazed & those fields still to be grazed. All the growth is happening on grazed pasture whereas the ungrazed pasture is still going backwards.
It is critical that cows don't go short of feed & lose body Condition Score in the month prior to mating. Most farms are faced with buying feed even though grazing conditions have been excellent. Many silage clamps are virtually empty. Time to Measure Pastures.
Ben, Sam, Michael & George from the DMS course for Herdsmen were out this week at Reaseheath College practising with the pasture platemeter. It's time everyone got out & measured pasture. Make sure new staff are using the platemeter correctly & that everyone on the team understands the Pasture Wedge Graphs. If you dont have them on your computer email me email@example.com
