INFLUENCE OF D I E T A R Y PROTEIN A N D ENERGY ON REPRODUCTIVE PERFORMANCE A N D NITROGEN METABOLISM IN FINN-CROSS EWES 1
University of Nebraska and U.S. Department o f Agriculture Clay Center, AlE 68933
SUMMARY
The effect of level of dietary energy and protein intake on reproductive performance was studied in 110 Finn-cross ewe lambs and in 404 Finn-cross yearling ewes during late gestation. Nitrogen metabolism was studied in 26 ewe lambs and 23 yearling ewes. Increasing digestible energy and crude protein intake for ewe lambs and yearling ewes during late gestation increased (P
