Influence of structure and composition of ryegrass and prairie grass-white clover swards on the grazed horizon and diet harvested by sheep. Effects of sward height and bulk density on bite dimensions of cattle grazing homogeneous swards. The influence of sward condition on rates of herbage growth and senescence in mixed swards under continuous stocking management. It is concluded that forb-rich swards are suitable for the preparation of high quality silages. This suggests trade-off between intake potential and other factors influencing dietary preference as sward conditions changed. The herbage from the swards was ensiled in laboratory silos and the silage quality analysed. The swards were cut four times per year. He followed this with experiments in which stocking rate was shown to have major effects on animal production from grazed swards. This management created strips for each sward type which were either immature and relatively short, or mature and relatively tall. At the time of sowing, there were marked differences in the amount of bare ground and sward height due to the fencing and cultivation treatments. On bare soil 39% of both the dung-covered and buried seeds germinated, in perennial grass swards 24-43%, and under tree canopies 10- 24% respectively. There is a clear vision of how commons should look; this is the short sward that maintains its 'green hue', which is neat and ordered. The sward type within which each animal was grazing was also recorded. Early spring defoliation patterns can condition the sward for mid-season growth by promoting leafier herbage with fewer reproductive tillers.
