The acrosomal status, which is frequently assessed for the estimation of the quality of the frozen-thawed semen, may be evaluated with the use of eosin-nigrosin, Giemsa, Trypan blue, Bismarck brown, Rose Bengal or Spermac stainings (Dahlbom et al.,1997; Dott & Foster, 1972; Watson, 1975). The goal of breeding is to inseminate the bitch four days before ovulation and then every two days until the final insemination at two days after ovulation. American Society for Reproductive Medicine. Over 70 percent of the sperm need to have normal forward motility, which correlates to 150 to 200,000 normal appearing sperm per sample. The most accurate measurements can effectively predict ovulation, but these tests are done in a laboratory. Lectins conjugated with fluorescein isothiocyanate, such as Peanut Agglutinin (FITC-PNA) or Pisum Sativum Agglutinin (FITC-PSA). Artificial insemination is a procedure that places sperm into the cervix or uterus around the time of ovulation in hopes of becoming pregnant.

Though it is not that uncommon for a dog to bleed after mating, by this time, the blood should be getting thinner, more watery, and lighter in color. It is most frequently carried out by experienced inseminators or by vets in practice. As PhD students, we found it difficult to access the research we needed, so we decided to create a new Open Access publisher that levels the playing field for scientists across the world. On the other hand, good in vitro semen quality does not always prove the fertilizing potential of a particular dog. I prefer long bovine pipettes to the short canine pipettes that are marketed for AI in dogs (Figure 21-1). Pregnancy can then be confirmed about 25 days later with an ultrasound. This is done by exposing the male to a female in heat.

Semen collection should be performed before the physical exam or any stressful procedures on the stud, or can be booked to another day (Freshman, 2002; Johnston et al, 2001). The lumen of the vagina is narrow, which can be appreciated when the endoscope is advanced cranially. Uterine tumors are rare in dogs, however, and are usually benign, if found.

Dogs dont always defer to what humans have decided is normal, and there are many, many exceptions to the rules. The concentration of spermatozoa in semen volume is usually assessed by cytometric method on the haemocytometer, such as the Thoma, Thoma-Neu, Brker or Neubauer chambers, with semen pre-diluted at 1:200. After that determination, semen can be collected by manual stimulation. An embryo can be transferred into the uterus several days later, or it can be frozen and saved for future use. Proestrus bleeding was persisting after four days post artificial insemination, therefore GnRH treatment has been applied. Pathological colours include: green-greyish typical for the presence of the pus in semen; red or pink-specific for erythrocytes contamination (haemorrhages from urethra or corpora cavernosa, prostatitis); yellow specific for urine contamination; and brown, if in the presence of blood.

(1999a) reported 25% higher pregnancy rate after intrauterine semen deposition when using scandinavian technique than after vaginal semen deposition. At this point, if there is not a limit to the number of inseminations, the first insemination is performed. The first of these is surgical insemination, which is by far the most However, it should always be remembered that the semen characteristics should be recheck 2-3 times at 1-2 weeks intervals, to confirm the male infertility.

Artificial insemination is a noninvasive procedure that places sperm directly into the cervix or uterus, increasing the odds of pregnancy. This should induce the vagina to begin contracting, which helps move the semen into the uterus. Unfortunately, this is not the most accurate method of determining ovulation. The different types of artificial insemination include: 5. For large breed dogs, these pipettes are too short, so modified pipettes used in cattle are frequently used. This procedure can be done laparoscopically, but because this requires additional equipment, training, and cost, it is generally not preferred. The evaluation of the percentage of live and dead spermatozoa and the percentage of morphological defects may be performed on the same nigrosin-eosin stained slides. I think I have a photo of Astrids that I could show you, hang about whilst I look. How long does it take for a dog to get pregnant after artificial insemination?

Or a commercial catheter in flexible latex tube presenting an inflatable balloon at the tip, like the Osiris gun, may be used; when inflated, this kind of device has the advantage of increasing the probability for intrauterine transport of the semen and of preventing semen backflow (Farstadt, 2010; Linde Forsberg, 2005a). Further evaluation of the vaginal cells is no longer necessary. A given dog begins her estrus cycle and her proestrus stage on day 1. A recent study showed that, in dogs, semi-quantitative methods for progesterone determination are less accurate than the quantitative methods, in particular at intermediate plasma progesterone concentrations (Moxon et al., 2010). Most often, artificial insemination with freshly collected semen is performed without fractioning the ejaculate, although for artificial insemination, only the second fraction is of interest (Thomassen & Farstadt 2009; Root Kustritz, 2003). It mainly dependends on the size of the dog, the size of the prostate gland, the animal age, the frequency of semen collection, the level of erotisation, and the volume of 3rd fraction collected.

Client education and technical councelling must complete the AI services to be offered by specialized practicioners, in particular when breeding a problematic bitch. Sperm incubation with hypo-osmotic solutions for 30 minutes at 37C, Objective evaluation of sperm cell motility, Determination of motility parameters for individual spz, Assessment of sperm fertilizing potential, - ZP-binding assay ( ZBA) using intact homologous oocytes, Membrane integrity and evaluation of live and dead cells, Combined use of several fluorescent dyes (i.e, propidium iodide PI and carboxyfluorescein diacetate, SYBR-14/PI) allow the identification of live cells, Fluorescent antibiotic chlorotetracycline (CTC), when bound to free calcium ions, is fluorescent. The key-issues to obtain good results by using canine artificial insemination are: The use of adequate number of viable sperm cells per dose, Adequate deposition of semen in the female reproductive tract.
