This study assessed in dairy goats the effect of hormonal induction treatments varying only 12 h in progestogen device permanence on estrus synchrony and fertility. In both Experiments, goats received 60 mg of medroxyprogesterone acetate (MAP) intravaginal devices for 6 (G6) or 6.5 d (G6.5), and 200 IU of eCG i.m. and 30 ?g of d?cloprostenol were i.m. applied at 24 h or 36 h before device removal, respectively. In Experiment 1 (n = 24), data related to sexual behavior and ovarian ultrasonography were recorded and, in Experiment 2, (n = 83) fertility was assessed after Flexible Time Artificial Insemination (FxTAI). In conclusion, increasing the time of intravaginal device permanence from 6 to 6.5 d resulted in greater estrus synchrony, but lower fertility in dairy goats subjected to estrus induction treatment at the non?breeding season. The G6 treatment resulted in high conception rate and can be recommended to support FxTAI programs in dairy goats in the non?breeding season. |

This publication presents and evaluates two methods for ex-ante analysis of the optimum number of recipient females in embryo transfer programs. The first method is determinist, based on algebraic deduction, while the second is based on stochastic simulation using a Monte Carlo method for generating the number of embryos in each collection. The results show that the deterministic method sustainability overestimate the biologic efficiency of the embryo transfer program and underestimate, consequently, the cost per pregnancy (up to 9,1%). The superiority of the stochastic simulations was more pronounced when considering high variability in the number of embrios produced, reduced number of donnors ana low cost per recipient. |
