Abstract
Two purified diets were compared for growth of lambs. Diet 25p contained primarily casein as the source of nitrogen and diet 27v contained primarily urea. Although the average gain and feed efficiency were higher for diet 25p, differences were not statistically significant. Diet 25p was also shown to sustain normal reproduction of ewes. From results of the present report and previous studies, the thesis is developed that 5% alfalfa in the casein-containing purified diets we have developed furnishes a factor(s) required for reproduction of ewes but not for growth of lambs.Keywords
