Goats are primarily raised in marginal, arid, and semi-arid production systems exhibit a seasonal reproductive pattern. Extending their season would enhance food security improve the economic viability of goat production. Therefore, objective this study was to assess effects SeVE supplementation during anestrus on ovarian activity anestrous goats subjected an estrus synchronization protocol. The response variables included induction (EI), ovulatory rate (OR), corpus luteum diameter (CLD), left right ovary diameters (LOD ROD), embryo implantation (EMBRYO), pregnancy rates (PREG). Adult, anestrous, crossbred dairy (n = 32) from northern Mexico (i.e., Comarca Lagunera, 26° N) were randomly assigned two homogeneous groups based age, live weight (LW), body condition score (BCS): (1) supplemented group (SeVE; n 16), received 5 mg selenium plus 350 IU vitamin E, (2) control (CONT; physiological saline. Estrus induced using combination progesterone (P4, 20 mg), equine chorionic gonadotropin (eCG, 400 IU), exposure male effect. While no differences (p > 0.05) observed between for LW BCS, EI, OR, EMBRYO, PREG higher < than CONT group. No CLD, LOD, or ROD. Thus, SeVE-targeted improved outcomes without affecting structure size non-dimensional action), suggesting that precision strategy certainly enhances efficiency. This possibly related selenium-induced increases P4 synthesis, antioxidant follicular development correlate with endometrial development, conceptus survival, growth, maintenance. Such improvements could contribute sustainability marginal regions Mexico, supporting increasing returns producers families.
