Abortion in Sows [PDF]

Acta Veterinaria Scandinavica, 1970
Of a total of 31,766 pregnancies 465 abortions were reported, in average 1.46 %. By comparison of the frequency of abortion at different times of the year a significantly higher percentage of abortion was found in sows inseminated during the summer months. No significant difference was found between 68 boars as to the frequency of abortion.
