Responsible breeding means only selecting dogs of exceptional conformation and character, to produce future generations. For vaginal AI a simple plastic catheter of proper length may be used, to which a plastic disposable syringe containing the semen is attached.

In alternative, the vulva may be elevated to just below the anus (as the bitch does when stimulated by the male dog) (Linde Forsberg, 2005a). Furthermore, in this species, ovulation of immature oocytes (primary oocytes, before extrusion of the first polar body) determines the need for a maturation period in distal oviducts that may last for 96-108 hours (Concannon, 2004, 2010; Tsuitsui, 1989; Tsutsui et al., 2009); for most bitches, the secondary oocytes present a life span of 24-48h (Tsuitsui, 1989).

The bitch usually presents a relatively long follicular phase and considerable variability exists in the onset of estrous behavior and acceptance of the male, making it difficult to determine occurrence of the LH surge and onset of ovulation in this species unless specific methods for timing the ovulation and estimating the fertile period are used (Linde-Forsberg, 1991). It is therefore important to check the region of praeputial opening before semen collection and to clean it. If the catheter is in the urinary bladder, the cranial part of the vagina and the cervix may be palpable above the catheter and also the tip of the catheter stands out more clearly, due to the thinner walls of the urinary bladder in comparison to those of the vagina (Linde Forsberg, 2005a). The assessment is based on the evaluation of the average percentage of progressively motile spermatozoa in a few different fields of the specimen. The estrogen cycle of a female dog is divided into three stages: 1, 2 and 3 estrogen (1 3), which can last between 3 and 21 days (the average duration is 9 days). 10988722_10155271005075151_119482796_o.jpg.

If she doesnt get pregnant during several estrus cycles in a row, the lining of the uterus continues to thicken until cysts form. A combination of the two methods has a pretty good success rate. The endoscope is introduced into the cranial narrow part of the vagina, while a flexible catheter is introduced cranio-dorsal into the external orifice of the cervical canal under the visual control performed through the endoscope. Worried about the cost of Artificial Insemination treatment? The success rate in dogs is lower, largely because canine semen is less stable when frozen. The mild bleeding 2-3 weeks after AI is abnormally long, but not unheard of and would not tell me that the AI did not take. Traditionally sperm cells abnormalities are divided into primary defects - originating from abnormalities of spermatogenesis and secondary defects - originating from abnormalities of semen maturation, transit through the ductal system and specimen preparation. Coverage and use of fertility services in the U.S. - issue brief. Except for those females, the AI catheter should be further introduced until it reaches the paracervical area, which can be palpated as a 1- to 2-cm-long, firm structure that ends at the cervix (a firm, rounded to ovoid structure, freely movable). official website and that any information you provide is encrypted On the following day (one day before ovulation), the progesterone level will be 2 to 4 ng/ml.
