Phenotypic Characterization of the Martina Franca Donkey: An Endangered Italian Donkey Breed.

The Martina Franca (MF) donkey breed () primarily inhabits the rural areas surrounding the homonymous municipality, as well as neighboring municipalities in the provinces of Bari and Brindisi, all located in the Apulia region of Italy. The objective of this study was to assess the current phenotype through the evaluation of 27 morphologic measurements. The study was conducted on 73 female and 18 male breeding animals from eight different herds located in central and southern Italy.

A rare case of adventitious placentation (diffuse semi-placenta) in a Jersey cow.

Placental abnormalities more frequently occur during pregnancy of somatic cell clones and may lead to pregnancy loss or dystocia. Adventitious placentation, or diffuse semi-placenta, is determined by the development of areas of accessory placentation between the cotyledons due to the abnormal growth of placentomes.After a full-term pregnancy, a 3-year-old Jersey heifer was referred for dystocia which resulted in the delivery of a dead calf.

Evaluation of Testicular Volume and Correlation with Sperm Production in Martina Franca Donkeys: A Parameter to Consider When Approving Breeding Jacks.

Good sperm production is a notable requirement for subjects intended for reproduction, particularly in endangered species, and it has been demonstrated that in horse stallions, this is correlated to testicular volume. The present study, which involved Martina Franca jacks, aimed to determine whether, also in this endangered breed, there is a correlation between the total sperm number (TSN) and testicular volume. Testes were measured with both ultrasound and a caliper.

The Lipidomics of Spermatozoa and Red Blood Cells Membrane Profile of Martina Franca Donkey: Preliminary Evaluation.

Fatty acid-based lipidomic analysis has been widely used to evaluate health status in human medicine as well as in the veterinary field. In equine species, there has been a developing interest in fertility and sperm quality. Fatty acids, being the principal components of the membranes, play an active role in the regulation of the metabolic activities, and their role on spermiogenesis seems to be of great importance for the resulting quality of the sperm and, thus, fertility.

The Clinical Effect of Xylazine Premedication in Water Buffalo Calves () Undergoing Castration under General Anaesthesia.

Castration is one of the most frequently performed surgical procedures in livestock. All methods of castration are associated with a significant degree of pain, affecting the patients' welfare. Limited information on species-specific protocols in buffaloes is available.

Metabolic and production parameters of dairy cows with different dry period lengths and parities.

To assess the effects of dry period (DP) length on metabolic, reproductive, and productive parameters, second- (SP) and third- (TP) parity cows were assigned to a traditional (9 weeks, T) or short (5 weeks, S) DP, obtaining four subgroups: second-parity cows with traditional (SPT = 8) and short (SPS = 8) DP, third-parity cows with traditional (TPT = 8) and short (TPS = 10) DP. Plasma insulin-like growth factor-I (IGF-I) and non-esterified fatty acid (NEFA) levels were assessed from 5 weeks before to 14 weeks after parturition. IGF-I concentrations were affected by parity (P < 0.

Postpartum Uterine Involution in Martina Franca Jennies.

This study investigated the postpartum (PP) uterine involution in nine multiparous Martina Franca jennies with at term, normal, and singleton foaling. Transrectal ultrasonography performed at Days 1, 3, 7, 14, 21, and 28 showed that the uterine tip diameters did not differ between the post-pregnant (PPH) and non-post-pregnant uterine horns (NPPH), whereas the diameter of the middle PPH was larger than the NPPH until Day 7 ( < 0.05).

Reference Ranges for Hematological and Biochemical Profile of Martina Franca Donkeys.

The Martina Franca donkey (MFd) is one of the largest Italian donkey breeds, considered as endangered breed. To support the conservation strategies, knowledge about the physiologic hematological parameters of MFds is needed. The aims of the study were to determine reference value for hematological and major serum parameters in a population of healthy MFds and to estimate the influence of age on these parameters.

Evaluation of Colostral Immunity Against Equine Herpesvirus Type 1 (EHV-1) in Martina Franca's Foals.

Eight Martina Franca pregnant jennies were selected in order to evaluate the transfer of colostral antibodies against equine herpesvirus type 1 in their relative foals after immunization with a commercial inactivated vaccine, compared with an unvaccinated group. Samples of serum and colostrums/milk were collected from jennies and foals under study starting from 10 min before and up to 21 days after the foaling. Specific anti-EHV-1 antibody titers were evaluated by means of a serum neutralization test, and the results obtained from both groups were analyzed.

Natural Occurrence of Ochratoxin A in Blood and Milk Samples from Jennies and Their Foals after Delivery.

An assessment of the natural ochratoxin A (OTA) exposure of seven Martina Franca jennies was carried out by analyzing blood and milk samples collected close to and after delivery. A total of 41 and 34 blood samples were collected from jennies and foals, respectively, and analyzed by ELISA. A total of 33 milk samples were collected from jennies and analyzed by the HPLC/FLD method based on IAC clean-up.

A Case of Adenocarcinoma of Uterus Masculinus in a Pomeranian Dog.

Persistent Müllerian duct syndrome (PMDS), or uterus masculinus, is a rare autosomal recessive form of male pseudohermaphroditism due to the failure of paracrine anti-Müllerian hormone (AMH) secretion by Sertoli cells or failure of the Müllerian ducts to respond to AMH secretion. The malignant degeneration of persistent Müllerian remnants is rare. In human medicine, few related reports exist.

Monolateral chronicon orchitis in a stallion.

Orchitis and epididymo-orchitis are inflammatory lesions of the testicle. We herein describe a case of monolateral chronic orchitis which occurred in a Tiro Pesante Rapido (TPR) stallion, born in 2002, with a history of good fertility. The stallion was healthy and asymptomatic although the left testis was found to be smaller as compared with the right one and was hard in consistency.

Prevalence, survival and subsequent fertility of dairy and beef cows with uterine prolapse.

The aim of this study was to evaluate the prevalence of uterine prolapse in cows and assess its effects on survival and subsequent fertility. Of 33,450 calving cows considered retrospectively, 216 (0.6%) developed uterine prolapse.

Laparoscopic Ovariectomy in Standing Mule Mares.

Mules are hybrids bred from the mating of a jack donkey and a horse mare, known for their strength and resistance and still used to work in agriculture. Although they have been for long considered sterile, evidence of estrus cycle has been demonstrated together with abnormal behavior related to ovarian activity. In this study, a bilateral standing laparoscopic ovariectomy technique using the LigaSure technology was applied in 10 mare mules for treating unwanted behavioral patterns.

Cryopreservation of turkey spermatozoa without permeant cryoprotectants.

In avian species, cryopreservation of semen is necessary for developing sperm cryobanks. It is very difficult, however to cryopreserve turkey sperm and have sperm be viable after thawing. Glycerol, the commonly used sperm cryoprotectant in many species, is toxic to sperm of avian species.

Biochemical blood analysis along pregnancy in Martina Franca jennies.

The availability of biochemical blood data specific for the pregnant condition are essential for the correct management of both normal pregnancies and also for the prompt recognition of every abnormality. Because of the lacking knowledge about biochemical blood analysis in the donkey along the entire pregnancy, the study was designed to provide first preliminary data about the values and possible changes of blood alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), alkaline phosphatase (ALP), creatine-kinase (CK), blood urea nitrogen (BUN), creatinine (CREA), uric acid (UA), amylase (AMY), gamma-glutamyl transferase (γ-GT), triglycerides (TRI), cholesterol (CHOL), total protein (TP), albumin (ALB), glucose (GLU), phosphorus (P), calcium (Ca), occurring from the beginning of pregnancy until parturition. The study was performed on 10 Martina Franca healthy jennies with normal pregnancy course and giving birth to mature, healthy and viable foals.

Immature ovarian teratoma in two heifers.

A 15 months-old Simmental heifer (SH) and a 18 months-old Marchigiana heifer (MH) were referred to the Faculty of Veterinary Medicine of Teramo (Italy). In the rst heifer, clinical examination of the vulva, vestibulum, and vagina showed no signs of disease and no discharge was detected. Palpation per rectum revealed a mass in the left portion of the abdominal cavity, closely attached to the tip of the left uterine horn.

Factors affecting pregnancy length and phases of parturition in Martina Franca jennies.

The knowledge of normal pregnancy length, duration of parturition stages, and neonatal early adaptation is mandatory for a rationale management of birth, especially in monotocous species with long gestations. This study reports data obtained from a large number of Martina Franca jennies with normal healthy pregnancies and spontaneous eutocic delivery of a mature, healthy, and viable donkey foal. Pregnancy lasts, on average, 371 days, and only the fetal gender significantly determines pregnancy length, with longer gestations observed in jennies bearing male fetuses.

Male isolation: a behavioral representation of the pheromonal 'female effect' in donkey (Equus asinus).

The appearance of a decisive component of the sexual response to chemosexual signals in the male donkey was investigated through a comparison of the variations in the time-span of the behavioral classes and units for the natural versus induced breeding seasons. The results demonstrate that there are significant variations in the length of the appetitive sexual behavior (ASB) and consummatory sexual behavior (CSB) under these two reproductive conditions. These differences are analyzed for the ASB, which is adaptable, compared with the stereotyped CSB.

Differences between epididymal and ejaculated sperm characteristics in donkey.

Spermatozoa acquire their motility and fertilizing ability during their passage through the epididymal canal. In the epididymal caput and corpus spermatozoa undergo several biochemical and metabolic changes while the cauda of the epididymis should be considered as the primarily site for storage of the spermatozoa. In the horse spermatozoa from cauda epididymis were collected and frozen, and the fertility of semen assessed.

Effect of dietary antioxidant supplementation on fresh semen quality in stallion.

In this study, the effect of dietary supplementation of organic selenium, vitamin E, and zinc on raw semen characteristics was evaluated. Ten stallions with normal fertility were divided into two groups: a control group (CG), in which standard diet was provided, and a treated group (TG), in which the standard diet was supplemented with 1500 mg of α-tocopherol acetate, 360 mg of zinc, and 2.5 mg of organic selenium on a daily basis.

Efficiency of different extenders on cooled semen collected during long and short day length seasons in Martina Franca donkey.

Artificial insemination with cooled semen is routine in equids because of its good fertility rates and relatively low costs. In several donkey breeds, especially in restricted populations, the use of cooled semen could be seen as the best way of improving reproductive performance and avoiding excessive inbreeding. Furthermore, most jennies have ovulatory estrous throughout the year, and thus, cooled semen could also be used during short day length season.

Molecular diagnosis of equid summer sores.

Equine cutaneous habronemosis, also known as "summer sores", is a parasitic infection caused by larvae of Habronema microstoma and Habronema muscae (Nematoda, Spirurida) released by dung-inhabiting fly vectors on abraded skin, skin wounds or muco-cutaneous transition sites. Larvae induce a local inflammatory reaction characterised by itching, granulomatous, ulcerated and, often non-healing, lesions. The diagnosis of summer sores may be unreliable mainly because of the limits of clinical and microscopic examination.
