The influence of liveweight on wool production and reproduction in high country flocks

摘要

Liveweight, fleece weight, and barrenness, and their inter-relationships, have been studied in four high country flocks#x2014;two flocks with Merinos and two with halfbreds. Within flocks barrenness decreased with increasing liveweight, on average by 3#x2013;4 for each 10 lb increase. Fleece weight within flocks increased by 8.2 for each 10 lb increase in liveweight. Fleece weight differences at the two-tooth stage are maintained very strongly in subsequent years.
