Genetic and phenotypic relationships between gestation length, litter size and litter birth weight in Yankasa sheep



Genetic and phenotypic relationships between gestation length, litter size and litter birth weight in Yankasa sheep



Animal Reproduction Science 34(2): 111-118



Data on 834 lambings collected during an 8-year period were analysed. Litter size, year of birth and litter weight at birth significantly affected gestation length, while the effects of parity, season of birth and sex of lamb were not significant. Ewes carrying single lambs had a gestation length longer by 1 day than those carrying twin lambs (151.9 vs. 150.9 days).
