Summary
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.
Resumen
El modelo clásico utilizado para analizar datos de la técnica de degradabilidad ruminal in situ fue propuesto originalmente por Thünen para el estudio de la respuesta de los cultivos a diferentes factores de producción. Con la finalidad de establecer el significado de la kd en el modelo de Thünen, se realizó un análisis matemático que indicó que esta constante representa el cociente entre la velocidad y la aceleración de la degradación ruminal. De manera similar, la constante kp representa el cociente entre la velocidad y la aceleración del pasaje ruminal.
