Reserves are lowest during the early vegetative period and highest at full maturity. Usually root reserves decrease between full bloom, and the mature seed state as tiller formation or new vegetative growth occurs. Replenishment is complete by the full bloom stage. Click to expand For alfalfa to persist the root reserves should be as close to maximum as possible when the plants are going into the winter. Reserves are used to develop heat and cold tolerance to maintain life during dormancy and to get the plants started next spring.

Once grazed off, little regrowth occurs, especially in late July and August. Click to expand In July and August horses consistently need good quality forage - the colt is getting bigger and the mare should be putting on conditioning in readiness for the collection period. Alfalfa can provide the nutrition required during this period. Grasses have lower protein and T.D.N. values when they mature than alfalfa. Meadow Brome is the newest pasture grass species available.
