AB  - Short-term measurements of fasting metabolic rate (FMR) of two medium heavy 
      breeds, Rhode Island Red (RIR), Light Sussex (SS), and their reciprocal crosses, 
      were recorded between 40 and 60 weeks of age. Pure breeds differed significantly 
      in fasting metabolism corrected for body weight, feather loss, and activity. 
      During lighted hours, FMR of RIR exceeded FMR of SS hens by .8 kJ/hr. For the 
      dark period the difference was 1.5 kJ/hr. Fasting metabolic rates of reciprocal 
      crosses fell between parental means. Heterosis in egg mass output of 5 to 6% and 
      3 to 4% in feed conversion ratio, respectively, did not increase FMR of crosses. 
      Heritability estimates for FMR within stocks were moderately high (FMRD: h2S = 
      .23 to .43). An adjustment for body weight, feather loss, and activity decreased 
      heritabilities, but a genetic component in FMR still persisted (h2S = .05 to 
      .22).
