A.S. Series 67-23
Plane of nutrition of the ewe before lambing and during early lactation is an important factor influencing lamb mortality. Previous studies at Antelope Range showed the importance of winter supplementation in lambing percentage and lamb survival and the importance of summer grazing rate on lambing percentage and weaning weight (Gartner, Lewis and Trevillyan, 1965). The intensity of grazing studies have been continued. From 1964 through 1966 a self-fed pelleted ration was compared with hand-fed prarie hay from lambing until being placed on summer pasture. Results of the year 1964 have been reported (Lewis, Gartner and Trevillyan, 1965).
