Abstract
The present study focused on establishing the predictive value of two tests of
sperm resistance and functionality on the post-insemination non-return rate
artificial in pigs, in search of a useful laboratory test at the
commercial. In three farms located in the departments of Cundinamarca, Caldas and
Cauca, 14 ejaculates were obtained from different males, to carry out
laboratory analysis of a commercial dose and perform artificial insemination with the
rest of the doses produced to evaluate the presence of estrus 18 to 22 days post-insemination.
A laboratory test was developed that consisted in determining the morphology, the
Plasma and acrosomal membrane integrity by iodide labeling.
Arachis hypogaea peanut propidium and agglutinin bound to isothiocyanate
fluorescein (PI /FITC-PNA, from the English name) after hypoosmotic stress, in
search for an elite population of functionally competent spermatozoa (EFC).
