Origin and comprehensive study of Thünen´s model to analyze data from in situ rumen degradability technique

RESUMEN

The classical model utilized to analyze data from in situ rumen degradability technique was originally proposed by Thünen to study the harvests responses to different production factors. In order to settle the meaning of kd in the Thünen´s model, a mathematical analysis was realized which indicated that this constant represents the quotient between the ruminal degradation acceleration and velocity. Similarly, the kp constant represents the quotient between the ruminal passage acceleration and velocity.
