Milk yield of 1/4 Finnish Landrace × 3/4 Merino Precoce ewes, rearing singles and twins.
A total of 14 ewes, 7 with twins and 7 with single lambs, were stocked at 8 ewes/ha on Trifolium subterraneum cv. Dwalganap and Woogenellup/Phalaris aquatica pasture for 116 days. Average total milk yields were 242 and 180 kg for ewes with singles and twins respectively (P≤0.01). Average daily milk yields were 2.14 and 3.47 kg (P≤0.001) for ewes with singles and twins respectively for days 1-56 of lactation, after which yields from both groups were similar. Lactation curves adapted well to Wood's model, with regression coeff. of 0.939 and 0.976 (P≤0.0002).
