Rams were introduced to the ewes on the 30th of September. As a synchronised breeding program was in place, a ewe to ram ratio of 8:1 was used to ensure maximum conception rates. One Texel ram was left with the ewes to pick up on any repeat breeders. Ewes were scanned on the 14th of December with an overall litter size of 1.85 lambs per ewe. Meal feeding will commence 8 weeks pre-lambing with ewes being grouped according to litter size.
