SORIA PARRA, Manuel E et al. Superovulation with Synchronization of Follicle Wave and Naturally-Induced Estrus in Holstein Cows. Rev. prod. anim. [online]. 2017, vol.29, n.1, pp. 40-43. ISSN 2224-7920.

The objective was to evaluate the effect of superovulation (SOV) with synchronization of ovarian follicular wave (SOFW) and natural estrus (NE) on the quality of embryos obtained in Holstein cows. 20 Holstein cows were selected as donors with a body condition score: 2.75 to 3.5; aged between 40 and 60 months; normal cycles; and who have not submitted reproductive problems. The cows were randomly assigned to treatment SOFW (n = 10) and NE (n = 10) treatment. The SOFW group was synchronized with intravaginal progesterone device plus estradiol benzoate at day 0 and FSH in decreasing doses for 4 days, 2 times a day from day 4; at day 6 the implant was removed and applied prostaglandin; on day 8, they were inseminated to 6:00 a.m. and 6 pm. At NE group, FSH was applied twice daily for 4 days in decreasing doses from day 10; prostaglandin on day 12 was applied and inseminated on day 14 at 6 am and 6 pm. In both groups embryos nonsurgically seven days after the first IA recovered. The results obtained in transferable embryos were 5.7 + 0.76 and 2.8 + 0.31 (P < 0.05) SOF and CN, respectively. It is concluded that the protocol SOFW produces more transferable embryos (grade 1 and 2) that the protocol NE.
