A line (E) of turkeys selected long term (40 generations) for increased egg production was reciprocally crossed with a commercial dam line (BD). The BD line was larger and had better conformation than the E line, but the E line laid more eggs than the BD line. Heterosis was negative and significant for BW at 8, 16, and 20 wk of age (both sexes) and at 50% production (females only). Values for heterosis ranged...
