Quality of semen stored at +15 degrees/16 degrees C as related to fertility of artificially inseminated swine.
Linear correlations between swine semen quality and fertility (birth rate and number live born pigs) were studied. Doses of swine semen with 4 x 10(9) motile spermatozoa were used after being stored at +15 degrees/16 degrees C . However, mean or high correlations could not be found. Low correlations occurred between head-acrosome anomalies, total anomalies and birth rate. It is likely that the doses of semen with 4 x 10(9) motile spermatozoa were too concentrated for the fertility level in the swine breed employed.
