Abstract

The reproductive performance of a hyperprolific swine genetic line (DanBred) was evaluated, subject to different post-cervical artificial insemination protocols, doses with different volume/sperm concentration: Reference protocol - 40 ml, 1.5x109; Experimental protocol - 80 ml, 3x109. The beneficiation period October-December was analyzed, in three consecutive years. Fertility and prolificacy (total and live births) were evaluated. Descriptive statistics of the variables under study were determined and an analysis of variance was carried out to evaluate the effect of the protocol. The fertility rate obtained with the experimental protocol (95.41%), was higher than that of the reference protocol (82.27%/93.79%). However, there was no significant influence of the type of protocol for total or live births, observing, respectively, values of 18.77±0.26/18.70±0.22 (experimental) and 17.80±0.35/16.56±0.26 and 15.91±0.34/16.71±0.22 (reference). In view of the discrepancy in the results referred in the bibliography, the adoption of a certain protocol requires prior assessment, under the specific operating conditions.
