The feasibility of selection for protein efficiency indices (PEI = grams body weight gain per protein consumed) in the early generations of a breeding program was studied with selected winter triticale (✕ Triticosecale Wittmack) lines. Weanling vole ( Microtus pennsylvanicus ) bioassays of seed from F 3 plants along with several F 4 plant selections from each F 3 indicated that selection for protein efficiency indices was practical as early as the F 3 generation. The evacuation period used to simulate beginning caecal weight reduced PEI values appreciably; however, only minor changes in ranking were found. Caecal accumulation had little effect other than increasing cereal protein efficiency indices without negating the nutritional comparisons among the early generation triticale lines tested.
