摘要: Abstract This study compared ewe and lamb performance in twin‐ triplet‐bearing/rearing ewes offered varying sward heights from day 64 (P64) of pregnancy until weaning at 87 (L87) lactation. Ninety‐six 90 triplet‐bearing Romney were randomly assigned on P64 to four replicated height treatments (2, 4, 6, 8 cm height). Within 24–36 h parturition (L1) the reassigned two (4 cm) L87. Ewes grazing 2 during significantly (P < 0.01) lighter P99 P132 L1 than 6 or swards. These also had lower dry matter intakes, condition scores, ultrasonic backfat depths. Litter size no effect intake, liveweight score throughout 0.05) intakes treatment...
