Heat stress is one of the main factors which adversely affecting the animal welfare and thus the economic benefits of the farms. Goat husbandry in Egypt tends to breed throughout the year. However, a high ambient temperature is the major restriction on the animal productivity. This effect is provoked when heat stress is accompanied by high ambient humidity. This study was aimed to study the effect of heat stress on the physiological, some hematological and biochemical parameters. Twenty-five goats were exposed to the daytime (30 days) after an initial 7 day shading period, while another 10 goats were exposed to the shading regimen throughout the entire 30 days as a control group. Heat stressed goats showed the decrease of the feed intake, body weight and growth rate. Physiologically, the rectal temperature, respiration and heart rates were observed to be significantly higher. Moreover, the red blood cells count (RBCs), hemoglobin concentration (Hb), and packed cell volume (PCV) were significantly increased, whereas an insignificant change in white blood cells count (WBCs). Also, the serum total proteins, albumin, glucose, urea and creatinine levels were significantly decreased. On the other hand, cortisol level were significantly increased in heat stressed goats. Our results indicated that heat stress produced a significant alteration in the physiological, some hematological and biochemical parameters.

Aim:This study was designed to evaluate the cardiac biomarkers and ultrasonography in prediction and early diagnosis of traumatic pericarditis (TP) in Egyptian buffaloes.Materials and Methods:A total number of 47 buffaloes were included in the study and divided into two groups: Healthy (n=10) and diseased groups (n=37). Diseased buffaloes were admitted to the Veterinary Teaching Hospital at Zagazig University, Egypt, with a history of anorexia, sudden, and severe reduction of milk production with no response to a previous medical treatment some animals had edema at the dewlap and congestion of the jugulars. These animals were subjected to clinical examination, evaluation by hemato-biochemical analysis including cardiac biomarkers and sonography.Results:The hemato-biochemical analysis revealed leukocytosis with a shift to left and hyperfibrinogenemia (indicating inflammation). Serum cardiac biomarkers including cardiac troponin I (cTnI), cTnT, nitric oxide, creatine kinase myocardial band, and lactic dehydrogenase enzyme were significantly increased in buffaloes with TP compared with control ones. Ultrasonographically, there were hypoechoic materials with echogenic fibrin interspersed in between the pericardial sac.Conclusions:The cardiac biomarkers may be considered a useful index in the early diagnosis of TP. Moreover, ultrasonography is an excellent tool for early prediction and diagnosis of such condition.

Aim:The present work was designed to study the incidence of obstructive urolithiasis and to apply comparative diagnosis to urine retention cases.Materials and Methods:A total of 78 non-castrated buffalo calves aging 3-11 months were included in this study, 68 calves were admitted to the Veterinary Teaching Hospital, Zagazig University, Egypt, during the study period with a history of anuria, and they were classified into three groups; intact bladder group (19 calves), uroperitoneum group (45 calves), and ruptured urethra group (4 calves). 10 apparently healthy calves were used for comparison. On the basis of history, clinical, laboratory, and ultrasonographic findings diagnosis was achieved.Results:There was a marked increase in the incidence of obstructive urolithiasis in winter season, especially in winter months of 2016. Calves within the age of 3-4 months and 6-8 months were mostly affected. Inappetence to anorexia, restlessness or depression, and abdominal distension were the most observed signs in the diseased calves. Laboratory findings revealed hemoconcentration and a significant increase in blood urea nitrogen and serum creatinine levels in all diseased groups. Hyperproteinemia, hypocalcemia, and hyperphosphatemia with electrolytes imbalance were recorded in the uroperitoneum group. Ultrasonographically, distended urinary bladder with distal acoustic enhancement revealed obstructive urolithiasis with intact bladder while anechoic fluid in abdominal cavity indicates uroperitoneum.Conclusion:On the basis of all findings, calves with intact bladder were in superior condition than those with a ruptured urethra and both were better than those with uroperitoneum.

Hypertrophic osteopathy (HO) is a diffuse periosteal reactivity of long bones and of poor prognosis as most cases died after short time or euthanized at the time of diagnosis. Early diagnosis is greatly important. Therefore, the present study aimed to investigate the clinical and different imaging features of HO in 12 dogs and hematological and biochemical changes. Twenty-two dogs were included in this study; 10 apparently healthy dogs were used as controls, and 12 dogs were diagnosed with HO. Diagnosis of HO-affected cases was based on a range of clinical, laboratory, and histopathological examinations as well as different imaging techniques. Two forms of HO were diagnosed: pulmonary (n=5) and extrapulmonary (n=7) HO. In pulmonary HO, pneumonia was recorded in five dogs. However, in extrapulmonary HO, mammary gland tumors and skin tumors were recorded in five and two dogs, respectively. Symmetrical non-edematous soft tissue swelling at the lower parts of the limbs with intensive bone proliferation and periosteal reactivity in the tubular long bones was observed. Anemia and leukocytosis, mainly lymphocytosis 50% or neutrophilia 45%, and elevated serum globulin, alkaline phosphatase, and C-reactive protein levels were the significant associated laboratory findings. The use of different diagnostic techniques was greatly important in the diagnosis of HO in dogs and provided information on the prognosis of such cases.

Background and Aim: Hypocalcemia in goats occurs around the time of parturition and is caused by decreasing level of calcium less than 10 mg/dL. This investigation characterized the hematological and biochemical profiles of peri-parturient hypocalcemia in goats and study the effects of hypocalcemia on uterine involution during the postpartum period on day 0 and then weekly postpartum (day +7, +14, +21, +28, +35, till +42). Materials and Methods: Forty-five polyparous native breed does age 3-5 years and weighing 40–60 kg were assigned to control and hypocalcemia groups based on their health history, clinical and biochemical findings. The control group included 10 clinically healthy pregnant does, and the hypocalcemia group included 35 late pregnant does that suffered from anorexia, weakness, muscle tremors of the hind limbs, and an inability to stand. Clinical examination and blood sampling in both groups were performed approximately 14 days before the expected time of kidding (day–14), at kidding day (day 0), on day +21, and +42 postpartum. Sonographic measurements were used to monitor uterine involution on day 0 and then weekly once the animal was postpartum (day +7, +14, +21, +28, +35, till +42) in both groups. Results: Results of sonographic measurement revealed that the hypocalcemia group had a greater (p<0.05) size of the uterus as assessed transrectally and retarded uterine involution when compared with the control group. Laboratory findings revealed that does in both groups showed lower red blood cells, packed cell volume%, and hemoglobin (Hb) concentrations on day –14 before kidding and day 0 when compared with postpartum measurements. A significant increase (p<0.05) in total leukocyte counts, neutrophil, serum glucose, and cortisol levels with a significant decrease (p<0.05) in lymphocytes. Significant decreases (p<0.05) in serum calcium, phosphorous, vitamin D, and total antioxidant capacity levels with significant (p<0.05) increases in serum malondialdehyde were recorded on day 0 and day –14 in the hypocalcemia group when compared with the control group. Conclusion: This investigation provides evidence that hypocalcemia in does causes both metabolic and oxidative stress during peri-parturient periods while also retarding uterine involution during postpartum periods.

A major clinical problem is digestive tract disorders in ruminants, especially cattle and buffaloes. One such illness is vagal indigestion (VI). In bovine practice, VI is not widespread yet gives the veterinarian a major diagnostic challenge under field conditions, with minimal diagnostic facilities. Both the vagus and the splanchic innervate the ruminant stomach, however, vagal nerve is responsible for the cyclic movements. Vagal indigestion in ruminants is a condition associated with functional stomach disorders, resulting in complete or partial damage, compression or inflammation of the vagus nerve.Vagal indigestion is also known as Hoflund's syndrome in cattle. It is characterized by impaired emptying of the

This study was carried out on a total of 40 animals (13 female cows, 14 cow bull and 13 cow calves of both sexes) with an age ranged from 1-5 years. Animals were admitted to Zagazig
