Splenomegaly in dogs is frequently diagnosed in veterinary practice. Establishing its morphological substrate is of major importance in choosing the therapeutic course and establishing the prognosis. The current study analyzed 194 dog spleens (190 surgically removed), submitted to the Pathology department, between August 2005 and October 2020. Macroscopic, cytological and histopathological examinations were performed. According to our results, localized/asymmetric splenomegaly represents 78.35% of the total cases examined. Splenomegaly was diagnosed mainly in mixed-breed dogs (22.68%), among the purebreed dogs the most affected being those of medium and large size, such as German Shepherd (11.86%) and Rottweiler (10.3%). Old age is a risk factor, 51% of the subjects being over 10 years old; 53% were males and 47% females. In 55% of all cases the splenomegaly had a non-neoplastic substrate, in 45% being represented by neoplastic processes. The most frequently diagnosed tumor was hemangiosarcoma (50.57%); the most common non-neoplastic diseases were hematoma (40.19%) and splenic congestion (26.17%).

Data regarding the pelvic limb lymph centres in ferrets is quite scarce in the literature, so the aim of this paper is to present the morphotopographic relationship between the lymph nodes and the muscles of the pelvic limb, given their adjacent position. The muscles of the pelvic limb are well developed. The medium gluteus is very powerful, though it lacks its lumbar portion, and it clings to the accessory gluteus muscle. The long digital extensor muscle is covered by the cranial tibial muscle. The fat in the inguinal region forms an adipose pedicle that embeds superficial inguinal lymph nodes. The superficial inguinal lymph nodes are represented by two structures located along the epigastric caudal artery. In literature, inguinal lymph nodes are described as inconstant, but we were able to identify them in all three examined bodies. The popliteal lymph centre is represented by a single lymph node with a globular appearance lying in the popliteal fossa. In the ferret, the lymph nodes have considerable dimensions.

In the present study, the productive performance of the rainbow trout for consumption (one year and a summer trout – P1+, two-year trout –P2, two-year and one summer trout –P2+) was analyzed, grew up in a fishing unit in south-eastern part of country. At the control fishing made bi-monthly, by weighing 100 fish of each pond and age category, the body weight was assessed, and based on it, the total and daily average gain in growth was established. Also, by sampling, the main body measurements were made and the body indices were calculated for the two summer trout. The primary somatometric data were processed statistically. The one year and a summer trout (P1+) registered a good growth dynamic, resulting in a total average gain in growth of 150 g / fish starting from pond population to the autumn inventory and an average daily gain of 0.83 g / fish. In spring-autumn growth, body weight grew by about 4.33 times (from 45 g / fish in July to 195 g / fish on autumn stock). In the October-March growth period, the two-year rainbow trout (P2) recorded a total average gain of 138 g / fish and a daily average gain of 0.92 g / fish, and the two-year and one summer trout (P2+) achieved a total average gain of 102 g / fish and a daily average gain of 0.85 g / fish. The economicity of body mass accumulation was good (specific consumption of 1.18-1.20 kg of combined fodder). The main somatometric characteristics of two-year rainbow trout (P2), demonstrates the proper body development and correctness of the body conformation of this age group, and the low variability coefficients (below 10%) highlight the high homogeneity of trout in pond. The two-summer rainbow trout showed optimal body indices values: fattening index = 1.67%, profile index = 3.61, quality index = 1.63, thickness index = 20.07%, carnosity index = 18.81%.

Diagnosis in captivity bird pathology requires, in most cases, gross postmortem examination and is a valuable tool regarding potential zoonosis, improving husbandry conditions or establishing the cause of disease, which, sometimes cannot be completed in live birds by the clinician. The present paper is a study of 35 captivity bird cases, belonging to different species, submitted to postmortem diagnosis at the Department of Pathologic Anatomy, from the Faculty of Veterinary Medicine of Bucharest. Results showed that different instruments and multiple approaches for examination and evisceration are required depending on the size of the bird, from ophthalmologic scissors and blades to instruments used in mammal necropsy. Regarding necropsy technique, feather examination showed stress bars for two cases and eight cases of self-mutilation, marking the importance of husbandry conditions. In addition, changes in the air sacs, internal organ topography and modified organ size were revealed in seven cases. Autolysis was present in 10 cases, due to improper or long conservation, compromising diagnosis or histopathologic examination. In conclusion, necropsies of birds kept in captivity require special care and knowledge, both in preparation and during the examination.

The neonatal period in small ruminants in the Northern Hemisphere usually starts in December. It is around this critical period that 10-12% of lambs and kids die in the first 72 hours of life because of poor colostrum quality and quantity. Concerning this fact, it is of importance that all pregnant ewes have adequate access to forages for a good colostrum quality, indispensable for the lasting growth of newborns lambs. To demonstrate the passive transfer of immunoglobulins from the colostrum, 10 samples of colostrum were collected from 10 individual ewes, followed by 10 samples of serum from their resulting lambs in the first day after lambing and at 8 days of age. The colostrum and protein serum levels were tested with: refractometry, using zinc sulfate turbidity test, qualitative sodium sulfite turbidity test. From all the colostrum samples collected, just 2 of them presented an acceptable quality of immunoglobulins. By negative correlation, the lambs’ levels of serum protein in day 1 and day 8 were high in all newborns. Although the current preliminary results are somewhat inconclusive, they outline the importance and practical significance of colostrum quality monitorization in ewes.

This study presents the perianaesthetic management for eight dogs, aged between 3 and 9 years old that underwent a hemilaminectomy surgical procedure for medullar decompression. The patients were presented at the Faculty of Veterinary Medicine in Bucharest for acute onset of posterior unilateral paresis. Following the examination through magnetic resonance imaging, medullar compression was diagnosed at different thoraco-lumbar levels and surgery was recommended (hemilaminectomy). Four of the patients were premedicated with Fentanyl 3 μg/kg and Midazolam 0.2 mg/kg administered intravenously (IV) and the other four received Dexmedetomidine 2 μg/kg, Butorphanol 0.2 mg/kg and Ketamine 2 mg/kg intramuscularly (IM). For induction Propofol was administered IV at a dose of 3 mg/kg and patients were intubated. All patients had an epidural anaesthesia with Lidocaine (2 mg/kg). Maintenance consists in the administration of a constant rate infusion (CRI) of Fentanyl (3 μg/kg per hour) and Ketamine (1 mg/kg per hour) for the first four patients and a CRI of Lidocaine (3 mg/kg per hour) and Ketamine (1 mg/kg per hour) for the other four patients. Post-surgery multimodal analgesia protocols ensured pain control during recovery.

During the last decades breeding dairy cows has severely affected the fertility of this species because this is a multifactorial objective that can involve genetic, environmental and managerial factors. The main purpose of this review is to describe the modification of different metabolites and hormones that are involved in cow’s fertility after calving. High milk yield during the fresh period predispose dairy cows to enter in negative energy balance (NEB). This happens because of fat tissue is mobilised faster than the liver is able to metabolize it. For a normal metabolize, the liver needs glucose. Non-esterified fatty acids (NEFA) offers an alternate source of energy but in the same time it can lead to liver accumulation of ketone bodies (acetone, acetoacetate and β-hydroxybutyrate). A small quantity of ketone production is normal for dairy cows but high amounts can lead to clinical and subclinical ketosis. Such diseases can predispose to a decrease milk production, a low fertility, and even culling.

The aim of the present study was to compare the antioxidant and antibacterial properties of summer savory (Satureja hortensis L.) from Muscel County flora (Romania) and wild thyme (Thymus serpyllum) from Lebanon. The aerial parts of plants were harvested in august, dried quickly and alcoholic extracts were prepared. Total phenolic content (TPC), total flavonoid content (TFC), DPPH radical scavenging activity, ferric reducing antioxidant power (FRAP) value, and antimicrobial properties were determined using the extracts. TPC showed that Lebanon thyme had higher concentration compared with Romanian thyme (13.78 ± 0.95 mg GAE/g DW and 12.14 ± 0.97 mg GAE/g DW, respectively). DPPH• was calculated as IC50 and the sample results were compared with gallic acid. FRAP results showed similar values 42.71 ± 4.24 μM Fe+2/g DW (Romanian thyme) and 39.55 ± 4.21 μM Fe+2/g DW (Lebanon thyme). The antibacterial activity of summer savory was found to have maximum effect against Staphylococcus aureus ATCC 9144. Bioactive compounds, measured as total phenolic content, were in higher concentration in both extracts which also relates to their antioxidant and antibacterial activities.

The paper presents the phosphorus content of pike-perch (Sander lucioperca) reared in Germany, in natural ponds and water recirculating systems respectively, compared with the same element measured from fillets imported from Kazakhstan and Russia and marketed in EU retail units from Hamburg Hanseatic City. It is based on the research data obtained in Max Rubner Institute, the Department of Safety and Quality of Milk and Fish Products among federal research institutes within the remit of the German Federal Ministry of Food and Agriculture (BMEL). The data have been processed into the proximate analysis parameters: pH, TVB-N, humidity and dry matter, ash percent, total phosphate, fat, protein and salt content. During the 10 months period of study (October 2013 - August 2014), were analyzed different sample types of pike-perch, refrigerated inland whole fish and frozen imported fillets. The phosphates content of fresh German pike-perch was situated approximately between 4.36 - 4.56 g P2O5/ kg of fish muscle, whereas the same parameter in frozen imported fish fillets analyzed were between 2.63 - 3.59 g P2O5/ kg. In conclusion, the use of added phosphates is usually suitable for fish fillet production. However, due to their waterbinding capacity which also could determine improved juiciness of pike-perch fillets, the added phosphates negatively influenced the fillets’ quality by forming an important amount of glaze, which after thawing led to unwanted weight loss, without bringing any threats to fish safety or consumers’ health. The water loss during thawing caused a significant depletion of previously added phosphates.

Immunoprophylaxis is the most affordable, effective and eco-friendly tool, which recommends it as the first option to control contagious agalactia in small ruminant flocks. The purpose of this study was to evaluate the immune response toward two marketed vaccines. Both products contain Mycoplasma agalactiae inactivated with formalin, on aluminum hydroxide gel. The trial has been carried out on a flock of 700 sheep. Each vaccine was administered to 250 animals according to the manufacturer instructions and 200 animals were in the control group. Serum samples were collected on vaccination days (0 and 21) and post vaccination, at 30, 90, 180 and 360 days. The immune response was assessed using a commercial indirect ELISA kit for antibody detection. Antibody titers increased rapidly after vaccination, reached the highest level between 21 and 30 days and declined after 180 days. No statistically significant differences in titers were identified between the two vaccines.
