Profil endocrinien de la lapine suivant la réceptivité sexuelle

Abstract

The aim of this work is to studie the endocrine profil and the eventual effect of sexual hormones on receptivity in female rabbit. The study was carried on 24 females: 12 locale Algerian population’s and 12 I.T.ELV synthtic line’s. Each group contained 06 receptive and 06 non-receptive females. The mesure of plasmatic rates focused on FSH, LH, Progesterone and estradiol. Results show no connection between hormone’s plasmatic rates and secual receptivity since no significant difference has been recorded between these rates in receptives and non-receptives rabbits. The studied rabbits show the following endocrine profil: FSH : 1.115 ± 0.585 ng/ml à 1.157 ± 0.405 ng/ml ; LH : 0.014 ± 0.008 ng/ml et 0.015 ± 0.01 ng/ml ; Progestérone : 0.3842 ± 0.197 ng/ml à 0.6827 ± 0.254 ng/ml ; Œstradiol : 34.91 ± 15.29 pg/ml et 41.58 ± 44.08 pg/ml.
