Quantification of Proceptive and Receptive Behaviors

It may be important to determine the degree of proceptivity or receptivity of a given female, especially when looking at interactions between individuals.

• Ex. quantification of lordosis behavior

  • strength of lordotic posture
  • frequency of lordosis
  • duration of lordosis

• lordosis quotient is calculated as a measure of a female’s receptivity

  • [# lordotic postures by female]/[10 mounts by male] X 100 = LQ
  • if a female shows 5 lordotic postures to 10 mounts by male, then LQ=50; this would be considered a moderately receptive female.
