Abstract PS115.c2016  cPoster.  aThe availability of shade during daily grazing time can modify the secretion of progesterone without effect on age of puberty in female West African lambs under tropical conditions. Future researches related to the potential impact of the high levels of progesterone in not luteal origin in tropical sheep are needed.  aBrazil  aMeasurement  aProgesterone  aReproductive performance  aSheep  aCordeiro  aEficiência reprodutiva  aHormônio animal  aOvino  aProgesterona  aSombreamento  aShading  aTropical zones1 aPIGLIACAMPO, A.1 aDRESCHER, K.1 aFONSECA, J.
