A full history of the management practices and prevalence upper respiratory tract disease (URTD) at 218 rescue shelters, breeding establishments private households with five or more cats was recorded. Oropharyngeal conjunctival swabs blood samples were taken from 1748 cats. The prevalences feline herpesvirus (FHV), calicivirus (FCV), Chlamydophila felis Bordetella bronchiseptica determined by PCR on swab samples. An ELISA applied to determine antibodies B. bronchiseptica. rates detection...
Early development in canine species follows a very specific pattern. Oocytes are ovulated at the germinal vesicle stage and meiotic resumption occurs oviduct. However, because of difficulties accurate determination ovulation time observation oocyte nuclear by light microscopy, these early events have not been fully described. Moreover, which sperm penetration is still uncertain since fertilization immature oocytes has reported vivo vitro. The aim this study was to establish exact timing...
There are a few investigations into endometritis in the bitch and its relationship with failure to conceive remains unclear. This may be because of difficulty collecting uterine samples for further investigations. Recently, transcervical catheterization by vaginal endoscopy has been introduced allowing evaluation endometrium. In this study, cytology bacteriology were evaluated 26 infertile bitches. Endometritis was bacterial origin most cases (70% affected bitches), but these results...
Canine oocyte maturation and fertilization take place within the oviducts under increasing plasma levels of progesterone (P4). In order to investigate role P4 in these processes, 51 beagle bitches were treated with receptor antagonist aglepristone at end proestrus 32 females kept untreated. Fifteen 13 control inseminated Days +1 +2 after ovulation (Day 0). Stages embryo development determined ovariectomy different time points ovulation. Aglepristone did not prevent but delayed resumption...
The absence of fertility problems in male dogs after a single treatment with deslorelin acetate (Suprelorin(®)) is well acknowledged. However, reports on the application bitch and information concerning implant are still limited. In this retrospective study, data induced spontaneous oestruses 39 bitches from 17 breeds, treated implants (4.7 mg Suprelorin(®), Virbac, France), were retrieved to assess post-treatment (ovulation rate, pregnancy rate litter size). Animals grouped according...
Over the last 10-15 years, long-acting GnRH agonists have become widely available. In field of small animal reproduction, most recent studies focused on use two compounds developed under form subcutaneous implants: azagly-nafarelin and deslorelin. Only latter has been commercially available for in male dogs, first Australia New Zealand, then several countries European Union since 2008. Although officially marketed this compound also studied bitches more recently queens. Some published papers...
Deslorelin 4.7 mg and melatonin 18 subcutaneous implants were studied in purebred male female cats, via questionnaires sent to French cat breeders, assess breed, age, duration of the contraceptive effect, fertility after use, changes behaviour side effects.
Hypo-osmotic swelling test (HOST) is used to assess the functional integrity of sperm plasma membranes in many species. The primary aim this study was a simplified HOST procedure for evaluation feline semen. second objective check if abnormalities can influence results test. Urethral semen collected from 19 male, domestic cats. In Exp. 1, performed different media (50 mOsm/kg fructose or distilled water), temperature (37 °C room temperature) and time (5 30 min). 2, potential effect on...
Contents In our study, a clinical and reproductive examination was undertaken in 204 dogs of five different breeds. Thyroxine thyroid‐stimulating hormone plasma concentrations were assayed order to assess the real incidence hypothyroidism associated with disease. Among these animals, only two breeds affected by (4.5% Dogue de Bordeaux 2.4% Leonbergers). Moreover, animals did not suffer from any Our study showed also that 70% male hypothyroxinemic compared Great Danes, English Mastiff...
The IGF system plays a crucial role in ovarian folliculogenesis, and changes IGF-binding protein (IGFBP) levels modulate bioavailability. Data from various mammalian models suggest link between body size, IGF1 serum female reproduction parameters. Among the vertebrate species, dog exhibits widest span height. Height is known to be positively correlated with concentration of IGF1. In this work, physiology 40 bitches exhibiting wide height, breed type was investigated. IGF1, IGF2, IGFBP3,...
An accurate timing of parturition is very useful for managing canine parturition. It generally accepted that in bitches occurs between 64 and 66 days after the luteinizing hormone peak. In this retrospective study, we determined pregnancy length different breeds its influencing factors dating it from estimated day ovulation (EDO), defined as when peripheral plasma level progesterone (P4) reaches 6 ng/ml. From January 2001 to December 2006, 162 pregnancies 151 53 were followed. Different...
Since most of dystocia end up in caesarean sections (C-sections), the history any problem during whelping is a good reason to plan advance further C-section. Our aim was confirm that on large sample and over an extended period time, mortality puppies <2 weeks age low, born after planned C-section using aglepristone as primer. Seventy-four C-sections 59 different bitches were included. Bitches monitored oestrus estimate day ovulation by progesterone assays; 60, 61 or 62 days ovulation, foetal...
