It was determined that Folltropin produced the highest number of total embryos, with 144 embryos in this trial, unlike Cebiotropin, which generated 78 embryos, which represents 54% of what Folltropin produced. When analyzing the quality of the embryos in percentage terms, Cebiotropin generated more embryos in grade one quality (95%), unlike Folltropin, which lacked 1.25% to match this value. The effectiveness allows to appreciate that Cebiotropin obtained an average of 59 % in the three collections carried out in the four donor cows; Being surpassed by Folltropin that reached 81% in these same conditions and for this variable. It is concluded that; folltropin presented greater effectiveness in terms of the production of structures, and this difference is also preserved in the number of embryos; The greatest cost benefit was obtained when using Folltropin within the superovulation protocols since the one obtained was almost double compared to its competition, this being due in the first instance to the number of embryos produced. |
