A total 60 boars collected 13 pig farms. Bacteriological mycological investigations performed immediately on raw samples, then at 48 120 h diluted randomly a new short-term modified extender...

Sexual development in mammals is based on a complicated and delicate network of genes hormones that have to collaborate precise manner. The dark side this pathway represented by pathological conditions, wherein sexual does not occur properly either the XX XY background. Among them conundrum individuals with at least partial testis differentiation even absence SRY. This particular condition present various including dog. Seven dogs characterized karyotype, SRY gene, testicular tissue were...

Solid organ transplantation remains a life-saving treatment for patients worldwide. Unfortunately, the supply of donor organs cannot meet current need, making search alternative sources even more essential. Xenotransplantation using sophisticated genetic engineering techniques to delete and overexpress specific genes in animal has been investigated as possible option. However, use exogenous tissue presents another host obstacles, particularly regarding rejection. Given these limitations,...

The present study aimed to detect microplastics in feline placentas and fetuses the early stage of pregnancy. For this study, 8 pregnant queens were evaluated. A standardized protocol for digestion biological matter was used, as well a plastic-free approach sample collection manipulation. Microplastics investigated by means Raman spectroscopy, with aim identifying their composition. Four eight animals contaminated, total 19 detected both fetal placental samples. Specifically, from cats 4 7...

Contents Contrast‐enhanced ultrasound with sulphur hexafluoride microbubbles was performed in seven healthy dogs without a history of reproductive pathology and histologically confirmed normal testes 42 chronic scrotal anomalies. All underwent orchiectomy histological examination. Enhancement patterns perfusion parameters (peak intensity regional blood flow) lesions were compared. Fourteen non‐pathologic 60 pathologic considered. Forty neoplastic (24 interstitial cell tumours, 9 seminomas, 7...

Male pseudohermaphroditism is a sex differentiation disorder in which the gonads are testes and genital ducts incompletely masculinized. An 8 years old dog with normal male karyotype was referred for examination of external genitalia abnormalities. Adjacent to vulva subcutaneous undescended were observed. The histology revealed Leydig Sertoli cell neoplasia. contemporaneous presence testicular tissue, vulva, compatible pseudohermaphrodite (MPH) condition.

In the last decade, progenitor cells isolated from dissociated endometrial tissue have been subject of many studies in several animal species. Recently, showing characteristics mesenchymal stem (MSC) demonstrated human, pig and cow uterine samples. The aim this study was isolation characterization stromal endometrium healthy bitches, a that after elective surgery is routinely discarded. Multipotent could be all bitches enrolled (n = 7). multipotency by their capacity to differentiate into...

Canine prostate gland abnormalities affect a large number of adult male dogs. In veterinary medicine, the commonly used methods to diagnose canine disease are digital rectal examination and abdominal ultrasound. We evaluated ability ultrasound contrast agent provide additional information about vascularity gland; such could be useful in detecting early staging known present. characterized ultrasonographic appearance 10 healthy dogs before after injection an (Levovist). Before injecting...

In the first days after birth is common to observe weight loss in puppies that should not exceed 10% of body at birth. The main causes are urine and meconium issued followed by non-recovery fluids expelled. present study aimed check outline growth curves boxer breed during two week life. our study, between 3th 5th day birth, have retrieved doubled their live weeks. We observed a mean 11.26±2.3 g (2.27%) Subsequently they recovered four with higher regained earlier condition still were heaviest 13.

Testicular tumours are the most common neoplasms in male dogs accounting for approximately 90% of all affecting genitourinary tract. Gray-scale ultrasonography combination with colour and power Doppler imaging has been well accepted as an accurate technique assessing scrotal lesions vascularization testis. Colour sensitivity low blood flows appears promising study testicular disorders. The aim this was to assess if ultrasound is a good tool investigation dogs, report sonographic features...

A five‐year‐old female cat weighing 3 kg was presented by the owner after noticing a large pink, bilobed mass protruding through vulva during labour. The in good condition, with appropriate lactation, and newborn kittens were nursing normally. uterus not reverted or invaginated at examination, there rupture of mesovarium, mesometrium uterine‐vaginal connection around cervix. Manual reduction prolapsed possible because torn ligaments. coeliotomy performed to remove ovaries, apex uterine horns...

The Boa constrictor is one of the most common reptiles bred in captivity. To achieve a successful breeding season, thorough knowledge females' reproductive activity necessary. In this regard, information on still rather scarce. aim present study was to monitor ovarian and embryonic development boas by ultrasound. We performed brief scans thirty non-anaesthetized snakes using portable ultrasound system 7.5-10 MHz linear array transducer (Esaote MyLab™ Classic). Ultrasound features,...

Insulin resistance (IR) in dogs is suspected when hyperglycemia present despite administration of insulin doses greater than 1.0 to 1.5 UI/kg. IR caused by increases counter regulatory hormones concentrations (glucagon, glucocorticoids, catecholamines and growth hormone). This study was conducted investigate the use aglepristone (RU 46534), a P4 receptor antagonist, for treatment diabetes mellitus bitches during luteal phase. All animals were treated with porcine zinc suspension (Caninsulin)...

The royal python (Python regius) is commonly bred in captivity. To have a successful breeding season, accurate monitoring of the reproductive activity necessary. use non-invasive methods exotics important order to minimize stress. For this purpose ultrasound has been anecdotally used monitor activity. However, there limited information regarding cycle species. aim present study female using ultrasonography and gonadal steroid metabolite measurements faeces. one hundred twenty-nine adult P....

In swine production, the economic gain in farrowing room corresponds to number of weaned piglets/sow per year. Pre-weaning mortality is at least 11–13% total losses within one herd, considering a previous 7–8% stillbirths. Piglet crushing by sow contributes significantly overall piglet mortality. It caused multiple factors related sow, and due modern husbandry along last 50 years. This study aimed compare three different designs crates during first days life relation piglet-crushing...

Dystocia is a multifactorial, life-threatening condition commonly affecting pet reptiles. Treatment for dystocia can be either medical or surgical. Medical treatment usually involves the administration of oxytocin, but in some species or, cases, this does not work as expected. Surgical treatments such ovariectomy ovariosalpingectomy are resolutive, invasive small-sized In paper, we describe three cases post ovulatory egg retention leopard geckos (Eublepharis macularius) successfully treated...

Fetal fluid contents have functions in protecting fetuses and are essential for fetal development maturation. However, little is known about the exact physiological of fluids development, as well changing composition throughout gestational period cats. In this study, biochemical amniotic (AMN) allantoic (ALL) was investigated, maternal serum pregnant queens. Eighteen queens were included study assigned to six different groups, D20, D25, D30, D40, D45 D60, according stage development. A total...

Two operators attempted to detect pregnancy ultrasonographically in 196 sows daily from 15 25 days after insemination; 20 unbred were also investigated. The probe was applied transcutaneously on the right abdominal wall near last three mammary glands. During each examination, embryos visualised and their transverse longitudinal dimensions measured. Pregnancy confirmed by an ultrasonographic detection of five first ultrasound diagnosis finally 30 32 insemination. accuracy less than 83 per...
