Abstract

Aprobability density function for the number of viable embryos produced after an in vitro fertilization program in Nellore donors was adjusted through data provided by the Brazilian Association of Zebu breeders. Results were based on 20,619 donors, 71,602 aspirations and the total of 509,643 embryos. The probability density function of the number of viable embryos was modeled using exponential distribution. Parameters fitting were carried out for the maximum likelihood using a non-linear gradient method. The precision level was RMSE = 0.040 and R2 = 0.98 for the representation of probability of number of viable embryos produced by Nellore donors by in vitro fertilization technique. To analyze probability density of embryo recovery (Beltrame, 2006) with in vitro fertilization adjust was used the curve comparison test through F test (Silva and Azevedo, 2002). There were no differences between the curves. These results suggest that there may be a unique and restricting factor that affects biologically the embryo production on the embryo transfer and in vitro fertilization techniques.

Key words: Data bank, donors, probability density, simulation.
