Abstract

Pasture and animal responses of Florakirk swards were evaluated at four “steady state” conditions (sward surface heights (SSH) of 5, 10, 15 and 20 cm), established by sheep under continuous stocking and variable stocking rate from August/98 until April/99. SSH were allocated to experimental units according to a complete randomized block design with four replications. The responses evaluated were herbage nutritive value (crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and lignin), ‘in vitro’ organic matter digestibility (IVOMD), morphological composition of the herbage as grazed and of the sward, herbage accumulation rate and animal performance live (weight gain per animal and per area). The CP content varied from 16 to 24% and IVOMD from 70 to 80%. Herbage accumulation rates as well as animal performance were higher in summer than spring due to a higher availability of growth factors.
