Extract

Feeding straw as the only roughage to housed ewes during the winter is gaining in popularity. This practice requires new grazing techniques because silage aftermaths might not be available in the summer to reduce stocking rates as grazing demands increase. It has been shown that set stocking ewes at either 22 or 30 ewes/ha and feeding a creep feed to the lambs ensured that all lambs were sold by August and gross margins/ha were increased (Brown, 1986). However, at these high stocking rates coccidiosis was a problem.

222 Mule ewes with their Suffolk or Polled Dorset cross lambs were divided into 6 similar groups. Each group were set stocked in a 1.4 ha plot so that 31 ewes with 57 lambs grazed at 22 ewes/ha, and 43 ewes with 79 lambs grazed at 30 ewes/ha.
