Optimal sward height for production in twin and triplet ewes

摘要：

Low birthweight lambs are associated with lower survival rates and lower weaning weights thereby limiting potential returns to sheep farmers.The nutritional requirements for both singleton‐ and twin‐bearing ewes are well established and Morris et al.(2004) identified 4 cm as the optimal sward height for single‐ and twin‐bearing/rearing ewes under continuous grazing systems.However, the feeding requirements of triplet bearing/rearing ewes under pastoral grazing conditions have only recently been researched in New Zealand.
