Abstract

We recorded conception rates and estimated pregnancy rates following second and later timed artificial inseminations (TAIs) after hormonal resynchronization on commercial dairy farms, using the so-called G6G protocol (PGF day-0; GnRH 2, 8 days; PGF 15, 16 days, GnRH 17 days; TAI 18 days), and the...

Abstract

When a male dog is not able to ejaculate, epididymal spermatozoa can be used to artificially inseminate the bitch. In the present study, two methods to collect epididymal sperm after castration were compared, i.e. the float-up method and the aspiration method. With the float-up method, more...
