SORIA PARRA, Manuel E et al. Antidiarrheal Effect of Anacardium occidentale L. Leaf Powder on Newborn Chicks. Rev. prod. anim. [online]. 2018, vol.30, n.2, pp.52-56. ISSN 2224-7920.

The aim of this paper was to compare the effects of two superovulation protocols: synchronization of the follicular wave (SFW), and natural estrus (NE) induction of embryos produced for transference in Holstein cows. Twenty cows were chosen as donors, with body condition (BC) of 2.75-3.5; 40-60 months old; 1-2 previous services per gestation, and without reproductive problems. Two superovulation protocols were applied: SFW and NE. SFW was not observed to produce more embryos than the NE in the blastocyst and morula stages.

Palabras clave : embryos; blastocyst; morula; superovulation.
