|Description:||Animal preparation prior to artificial insemination (AI) in goats usually involves a combination of intravaginal devices containing progesterone/progestagens plus PGF2?? analogues and gonadotropins, being eCG the most used. The use of intravaginal devices soaked in synthetic progesterone analogues requires milk discard for 60 days. Progesterone soaked intravaginal devices, as synthetic ones, are associated with more animal handling and discomfort. In addition, it leads to environmental impacts because it generates more residues. On the other hand, eCG has presented continuous restriction due to animal welfare issues associated with its production (Vilanova et al., Animals, 9:1053, 2019) and it has been substituted by hCG for this purpose. This study tested the efficiency of estrus induction by light program followed by estrus synchronization protocol with two doses of cloprostenol 7.5 days apart and gonadotropins to provide suitable condition able to support fixed time AI (FTAI) during the non?breeding season in dairy goats.|
