  1. 1 The effect of method compares pentobarbital sodium vs. mechanical cervical dislocation (MCD) vs. manual cervical dislocation (CD)
  2. 2The effect of age compares the response of pentobarbital sodium and MCD between 8 and 18 w.o. turkeys
  3. a,bIndicates differences observed within column (difference within age)
  4. c,dIndicates differences observed within a row (difference within method)
