The effect of variation in the rate of stocking on the per animal and per acre performance of grazing animals on pasture has been examined. From this exmination a theory has been developed which attempts to explain, in the instantaneous context, the relationships which exist. In general, for a given sward-animal system the theory indicates the following:
1. As stocking rate is indicated gain per animal is constant at a maximum until the rate of stocking is such that the total forage consumed is equal to the total forage available. Beyond this point gain per animal is inversely related to stocking rate. As the rate of stocking continues to increase a point is eventually reached at which the animals neither gain nor lose weight. Further increases in the stocking rate beyond this point result in a loss in weight which is inversely related to stocking rate.
2. As the rate of stocking is increased there is a linear increase in gain per acre until a
maximum is reached at the point at which the total forage consumed is equal to the total
forage available. Beyond this point further increases in the stocking rate result in a linear decrease in gain per acre.
A feeding expereriment was conducted using rats offered measured amounts of a standard laboratory ration. The results of this experiment show that the theory is adequate for many purposes. |
