Ultrastructural Findings

During postslaughter inspection of a 4-year-old male dromedary camel ( Camelus dromedarius), numerous small nodules to large masses up to 4 cm in diameter were found on the serosal surfaces of forestomachs, large intestines, mesentery, liver, and spleen. Grossly, the masses were discrete, round, smooth, and white to gray that bulged from the serosal layer. Cut surfaces of the masses were discrete, round, white, and relatively homogeneous without any necrotic foci. Histopathologically, the masses were encapsulated and composed of a mixture of round and spindle-shaped cells in loose whorls of neoplastic cells with small elongated hyperchromatic wavy nuclei and a small amount of pale eosinophilic, poorly defined cytoplasm. Masson’s trichrome staining showed mild amounts of collagen fibers forming an irregular, loose stroma. In immunohistochemistry, immunoreactivity for the Schwann cell marker (S100) was diffusely positive in the neoplastic cells. The immunoreactivity for CK, c-kit, and CD34 were negative. Ultrastructural examination confirmed the tumor was entirely formed of neoplastic Schwann cells. On the basis of the histopathological, immunohistochemical, and ultrastructural findings, the tumors were diagnosed as multicentric fibromyxoid peripheral nerve sheath tumor (multicentric schwannoma). This tumor has not been previously recorded in camel worldwide.

AbstractEffects of two different management systems on male dromedary camel hormones, behaviors, and semen parameters were documented. Camels (n=6) were tested under two management systems: (i) housed in single boxes with 1-h freedom (H23); (ii) exposed to females for 17 h (from 3.30 p.m. to 8.30 a.m.) and then housed (ConExF). Blood was collected every morning; camel behavior was recorded twice a day: (i) from 7:00 to 8:00 a.m. to determine the short effects; (ii) from 2:00 to 3:00 p.m. to determine the long effects. Each camel underwent a female parade and semen collection thrice a week; sexual behavior, libido, and semen parameters were assessed. Testosterone and cortisol concentrations were higher in ConExF than H23. Compared to the H23 group, ConExF group spent more time walking, standing tripods, and looking outside their pen/box but they spent less time eating, ruminating, resting, standing, and showing stereotypical behaviors. In the morning, ConExF group spent more time walking, ruminating, and showing typical sexual behaviors compared to themselves during afternoon time and the H23 group. However, in the afternoon time, ConExF camels put more time their heads outside the box through the window and showed higher frequencies of stereotypies, probably due to a higher level of frustration. While the sexual behavioral score was higher and ejaculates showed a higher fraction of milky white and white-colored semen in ConExF than H23 group, their libido was similar. Overall, 17 h of exposure led to an increase in testosterone and cortisol levels, enhancing sexual behavior and semen color, but leading to frustration.

Abstract The study was carried out in seven reproductive herds of pigs. In three of them reproductive disorders were observed. Three herds consisted of 10-50 and four consisted of 120-500 adult sows and they were called small and medium, respectively. Fifty-seven adult sows were randomly selected from herds. Serum samples were tested using the complement fixation test and swabs from both eyes and from the vaginal vestibule were examined using real-time PCR. All serum samples were negative. Infected sows were present in each of the study herds. In total, there were 28 positive samples (53%, 28/48) in real-time PCR in sows with reproductive disorders and 35 (53%, 35/66) in sows selected from herds without problems in reproduction. One isolate proved to be Chlamydophila pecorum, whereas all the remaining were Chamydia suis

Objective: To assess the potential hematobiochemical alterations in healthy dromedary camel during the different stages of lactation. Design: Randomized controlled study. Animals: Fifteen healthy female dromedary camels, with mean body weight of 499.6 kg and mean age of 20 years. Procedures: Camels were categorized into 3 groups' according to their stage of lactation: group 1, early lactation (1-3 months), group 2, mid-lactation (four-6 months) and group3, late lactation (≥ 7 months). Blood samples were collected from every animals for hematological and biochemical evaluation. Results: Total erythrocyte count (TEC), hemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), total leukocytes (TLC), lymphocytes, neutrophils, monocytes, Calcium, glucose, aspartate aminotransferase (AST), alanine transaminase (ALT), gamma glutamyl transferase (GGT) and alkaline phosphatase (ALP) confirmed significant (p < 0.05) variation between different stages of lactation. However, non-notable (p > 0.05) dissimilarity were located in packed cell volume (PCV), mean corpuscular hemoglobin concentration (MCHC), in organic phosphorus (P), magnesium (Mg), cholesterol, total protein (TP), albumen, globulin, blood urea nitrogen (BUN) and creatinine kinase (CK) in the course of different ranges of lactation, Conclusion and clinical relevance: The results of this investigation may be useful as reference guide for dromedary camel to evaluate the metabolic health status at different stages of lactation.

The quality, safety, and suitability of animal fat for processing of a specific meat product is a critical issue. Increasing the human awareness about the health aspects associated with increased intake of animal fat, makes camel fat a suitable raw material for meat processing due to its excellent nutritional contribution. Therefore, the target of this study is examination of the sensory, physicochemical, fat oxidation, fatty acid profile, and other quality parameters of camel fat to evaluate the feasibility for processing of different meat products. To achieve this goal, 30 fat samples each from the hump, renal, and mesentery of Arabian male camels were investigated. The results showed that both the renal and mesenteric fat had honey color and medium-soft texture, while the hump had greyish-white color and hard texture. The sensory panel scores were significantly different between the hump and other fats. Hump fat had significantly (P<0.05) higher moisture, protein, and collagen content, while higher fat content was recorded in mesenteric fat. The fatty acid analysis showed that hump had high SFA and very low PUFA in comparison with both renal and mesenteric fat. Camel fat had high oxidation stability, and the mean values were very low in comparison with the levels of quality and acceptability. The ultrastructural analysis showed that hump fat had high elastin fibers which increase its hardness. The results indicated that both renal and mesenteric fat were more suitable for the production of various meat products than the hump.
