Ovulation rate, number of lambs per lambing and embryo mortality in DLS and Finnish Landrace sheep and seven of their crosses



Ovulation rate, number of lambs per lambing and embryo mortality in DLS and Finnish Landrace sheep and seven of their crosses



Bulletin, Agriculture Canada (10): 32-34



Data on DLS (Dorset X (Leicester X Suffolk)) sheep, DLS crossbreds with 1/8 to 7/8 Finnish Landrace (FL) inheritance and FL sheep were analysed. Ovulation rate ranged from 1.69 for DLS sheep to 3.53 for FL sheep, and number of lambs born per ewe from 1.56 for DLS sheep to 2.54 for FL sheep. The DLS X FL sheep had higher heterosis than any other crossbred for ovulation rate and number of lambs born per ewe.
