| Popis: | An attempt is made to establish a relationship between herbage utilization, pasture productio8n, and animal performance per unit area. When pastures are rotationally grazed, it appears that the highest pasture yield and animal production per unit area w’ill result only if feed demand is closely matched with supply so that little stubible is left after grazing. Experimental data indicate that the aim should be to ach’ieve at least 60% single grazing utilization of the total herbage on offer as long as in so doing overgrazing does not occur. Futu’re work is likely to show the need for an even greater degree of u t i l iza t ion i f per-hectare product ion is to be maximized. Limited data suggest that overgrazing of ryegrass pastures commences when they are grazed below 2 cm, wh’ile with more upr ight grass spec ies th i s s ta r t s when defo l ia t ion *is c loser than 10 cm. |
