Conteúdo: 	The aim of this study was to evaluate the impact of increased shadow supply in integrated crop-livestock-forest systems onin vitro embryonic development and physiological parameters related to stress response in Nellore heifers (Bos indicus). For thestudy, animals (n= 16) were randomly divided into two groups and kept in areas with different afforestation systems, theintegrated crop-livestock-forest (ICLF) and the integrated crop-livestock (ICL) system. The microclimate of the ICLF systemprovided better comfort conditions than ICL. No differences of respiratory rate, rectal temperature, cortisol, T3, T4, oocytequality, and cleavage rate between the systems were verified. A higher blastocyst rate was observed in the ICLF (p<0.05).Theresults demonstrate that Nellore heifers managed in ICLF during summer in Midwest of Brazil showed higher production ofin vitro embryos, without typical changes in its physiological parameters. The results observed in the present study indicate thatzebu females are able to respond satisfactorily to the intense heat conditions; however, we believe that the long period to whichthese animals are exposed to these conditions interferes in the oocyte competence and embryo development.
