For vaginal AI a simple plastic catheter of proper length may be used, to which a plastic disposable syringe containing the semen is attached. However, there are key considerations when performing artificial insemination. The estrus period lasts until three days after the birth of a baby. If in the AI with fresh semen the success of the procedure is strongly related to the quality of semen used and the moment for AI (Table 9), when using chilled semen both the quality of semen and the site of semen deposition are important factors for success, whilst in the AI with frozen semen, the intra-uterine semen deposition is critical (Table 10). Results obtained by Linde-Forsberg et al. Further evaluation of the vaginal cells is no longer necessary.

After ovulation, the progesterone levels rapidly rise and can be anywhere between 15 to 90 ng/ml. Artificial insemination; Bitch; Breeding management; Norwegian catheter; TCI; Transcervical.

To reiterate, for dogs, bleeding is the beginning, not the end, of their fertile stage, so if she mates within the first 9 days and bleeds lightly afterward, it does not necessarily mean that there is a problem. Artificial insemination is the collection of semen from the male and the subsequent insertion of the collected semen into the female. Schematic representation of the major morphological changes of the predominant epithelial cell in the vaginal cytology during the dog estrous cycle. The penis and collecting cone are firmly held in place with the collectors hands, stimulating the constriction of the female during a normal breeding.

It is necessary to palpate the end of the catheter and the cervix through the abdominal wall. Furthermore, a tendency exists to increase the demands for the use of frozen/thawed semen over fresh semen AI, as part of breeding tools for genetic improvement. Evaluation of sperm morphology should be completed microscopically using oil immersion, using an objective of x100 or x 125. For example, if the test comes back negative, the woman may still be pregnant. Hence, subsequent to the increase in the artificial insemination demand among dog breeders and owners and the broaden of the AI to preserved semen as a management tool in canine breeding, as through international exchange of frozen semen, inbreeding within breeds can be reduced.

Semen evaluation is also frequently performed in the absence of known reproductive pathology, upon request of the owner. One of the most important step of conventional semen assessment is the subjective evaluation of progressively motile spermatozoa (Spz) under contrast-phase microscope. Please enable it to take advantage of the complete set of features! It is possible to use vaginal endoscopy to determine the fertile period although it does not allow accurate timing of ovulation. On the basis of analysis of 327 inseminations Linde-Forsberg et al. 80% successful rate.COMMENT DOWN BELOW YOUR QUESTIONS.

Based on the last two years inseminations performed at the clinic (with a global success rate of around 75%), using a comercial kit for progesterone determination, fresh semen and intra-vaginal deposition (2 AI, 48h apart), it was found that when inseminations were performed with progesterone levels above 8 ng/mL a higher success rate and a closer to predicted whelping dates were achieved (Table 11), comparing to inseminations at lower levels of progesterone (2.5-8 ng/mL). Additional information on the shipment regulations may be obtained throught the references Linde Forsberg, 2001, 2005b.
