HAVING enough paddock feed over the winter months can be a challenge, but do you realise how much of an impact grazing decisions have on the regrowth of your pastures?
Within three days of being nipped off by a grazing animal, a new leaf emerges from the remnant of the plant.
Most of the energy of the plant is produced through the leaves capturing sunlight and converting it into sugars for the plant to use to grow additional leaves and replenish root reserves.
If this new leaf is grazed off again before it has had a chance to grow to full length and start producing energy, the regrowing plant must utilise stored energy in the remaining stem and root material to try and push out a new leaf again.
Over time if this plant is continually grazed off as a one or two leaf plant, it simply runs out of energy and dies, resulting in a thinning of the pasture mass.
Many producers therefore utilise rotational grazing in their farm management system.
