CONTROL DE LA ONDA FOLICULAR(1) El control de la onda folicular es una parte esencial para lograr una sincronizacin precisa en combinacin con una buena fertilidad.

(2) Normalmente comprende induccin de la ovulacin, atresia folicular o luteinizacin folicular. Resultando en la emergencia de una nueva onda folicular. (3) La onda ocurre: 1 da luego de usar GnRH, 3 das luego de usar 5 mg de 17- Beta B, 4 das luego de 1mg BE y 5/6 das luego del CPE y del valerato de estradiol.

RE-SINCRONIZACIN:EL ENFOQUE DE LA RE-SINCRONIZACIN ES PARA:

AUMENTAR % DE INSEMINACIN, ENTRE VACAS QUE NO CONCIBEN A LA 1RA IA y MEJORAR LA DETECCIN DE CELOS

SIMPLIFICA TIEMPOS DE DE INSEMINACION

PERMITE RE-TRATAMIENTO DE LAS VACAS EN ANESTRO

PERMITE UN TEMPRANO DIAGNSTICO DE PREEZ EN ANIMALES NO RETORNADOS A LA 1RA IA

EL XITO DE LA RE-SINCRONIZACIN SE REFLEJA POR SIMILARES % DE NO RETORNO y SU CONCEPCIN

RE-SINCRONIZACIN:

LA PROGESTERONA NO ESTIMULA MUCHO LOS ANIMALES NO CCLICOS PERO CONCENTRA EL RETORNO AL SERVICIO
