dc.description | The article concerns seasonal variations that occur in swine semen quality. Several studies on the effect of climatological
conditions on the reproductive performance of the bull and the ram had been conducted, but there was relatively little research performed to substantiate fertility patterns in boars. A study to examine the variation in swine semen quality and to determine when the semen quality values were lowest during the breeding period was presented for the reader. Conclusions were used to resolve what effects the extreme North Dakota temperatures had upon sperm production and potential fertility in boars maintained in extremely low ambient temperature conditions. If the semen characteristics examined in this study were valid criteria of a boar’s fertilizing capacity, then under practical management conditions, a cold environment should not damage the male’s contribution to conception rate and litter size potential. | |
