Effect of time of insemination relative to ovulation on fertility with liquid and frozen boar semen.

Theriogenology

Waberski D, Weitze KF, Gleumes T, Schwarz M, Willmen T, Petzoldt R.
PMID: 16727588
Theriogenology. 1994 Oct;42(5):831-40. doi: 10.1016/0093-691x(94)90451-n.

Precise data on fertility results following peri- and postovulatory insemination in spontaneously ovulating gilts is lacking. Using transcutaneous sonography every 4 h during estrus as a tool for diagnosis of ovulation, the effects of different time intervals of insemination...
