Abstract

Vaginal smears taken from 42 bitches were examined and the results were compared with serum levels of progesterone measured by RIA and ELISA. With ELISA (Hygia RPT progesterone test), it was possible to differentiate low (<3.9 ng/ml) and high progesterone levels (>4.2 ng/ml). Timing of artificial insemination or mating of the bitches using...

Abstract

Six photographs of Technovit casts of the ewe cervix are presented and discussed. The occlusive structures are designated plicae infundibulares (six) and plicae semilunares (two). Present methods of artificial insemination of ewes using a stiff catheter are unsuitable.

Abstract

Cervico-tubal contractions, resulting in the rapid transport of semen to the oviduct, were observed only during the second half of oestrus. Animals should be artificially inseminated during the latter half of oestrus, given the survival rate of spermatozoa. This is especially true for animals with...

Abstract

Three oestrous ewes were inseminated prior to ovulation with labelled, thawed spermatozoa, and were killed 20, 75 and 120 min later. At 20 min, significantly fewer spermatozoa were in the upper cervix, uterus and oviducts than at 75 and 120 min. Significantly more spermatozoa were in the oviducts...

Abstract

Fresh semen and seminal plasma, labelled with 131I, were deposited intracervically in 5 and 2 females resp. at synchronised oestrus. Ewes in each group were slaughtered 1-18 h and 2 h later resp. Radioactivity was measured in 14 sections of the genital tract. Seminal plasma was found in the cervix...

Abstract

Labelled semen was followed by gamma camera (Nuclear, Chicago) at 10- to 20-min intervals for up to 150 min from insemination. Results are illustrated and described for females inseminated at induced oestrus with fresh semen and for females inseminated at spontaneous oestrus with killed...

Abstract

Oestrus was induced in 611 gilts and 762 sows, and insemination took place twice in 1 day on display of the standing reflex in the presence of a boar. For 315 experimental gilts and 377 sows, 5 IU oxytocin were added to the semen before each insemination. In experimental gilts, the duration of ...

Abstract

A Russian instrument, the "Oestrometer-2", was used to measure the electrical resistance of the mucosa of the vaginal vestibule in 700 and 39 synchronised heifers and cows resp. Measurements were taken once or twice daily from days 3 or 4 to day 8 after the end of synchronisation treatment. Ovarian ...
