Respiratory diseases of cattle represented the most important health and economic problems of cattle rearing. It was possible to diagnose ultrasonographically bronchopneumonia, consolidation, pulmonary emphysema, pleural effusion and pleuritis. The study aimed to correlate between the changes in clinical findings and laboratory assays mainly haematological pictures and serum acute phase proteins (APPs) i.e. haptoglobin, and the characteristic ultrasonographic findings in bovine respiratory diseases and their importance in differentiation between upper respiratory diseases and lower respiratory diseases in cattle. A total number of 84 cattle were included in the study and divided into 3 groups: healthy control group (n=15), upper respiratory diseased group [URG] (n=29) and lower respiratory diseased group [LRG] (n=40). The animals were admitted to the Veterinary Teaching Hospital at Assiut University-Egypt with a history of anorexia, respiratory distress, nasal discharge, cough and/or abnormal lung sounds. These animals were undergoing clinical and ultrasonographic examinations as well as laboratory analyses. Regarding to the ultrasonographic findings, the diseased cases were classified into URG and LRG. Ultrasonography differentiated many of the affections such as bronchopneumonia (n=16), Lung consolidation (n=12), pulmonary emphysema (n=8), and pleuritis and pleural effusion (n=4). Neutrophilic leukocytosis was reported in URG and LRG. The biochemical assays revealed significant elevation in serum levels of haptoglobin, fibrinogen, total cholesterol, triglyceride, high density lipoprotein cholesterol and very low-density lipoprotein in URG and LRG. Serum albumins were remarkably (P<0.05) decreased in URG. The study concluded that thoracic ultrasonography considered a diagnostic tool in cows with respiratory diseases because it determined the location and extent of the lung lesions as well as the severity of the affection. APPs and lipid profile used as biomarkers for the diagnosis of bovine respiratory diseases.

OBJECTIVE To compare intraoperative and short-term postoperative variables pertaining to laparoscopic ovariectomy (LapOVE) and open ovariectomy (OVE) in rabbits (Oryctolagus cuniculus). ANIMALS Twelve 4− to 5-month-old female New Zealand White rabbits. PROCEDURES Rabbits were randomly assigned to undergo LapOVE (n = 6) or OVE (6), with a vessel-sealing device used to seal and transect the ovarian pedicles. Laparoscopic ovariectomy was performed with a 3-port approach. Variables were measured during surgery (surgery and anesthesia times and incision lengths) and for up to 7 days after surgery (food consumption, feces production, body weight, vital parameters, blood glucose and cortisol concentrations, abdominal palpation findings, facial grimace scale scores, and ethograms). RESULTS Mean surgery (43.2 vs 21.7 minutes) and anesthesia (76.2 vs 48.8 minutes) times were longer and mean incision length was shorter (24.0 vs 41.5 mm) for LapOVE versus OVE. No significant differences in postoperative variables were identified between groups. During LapOVE, small intestinal perforation occurred in 1 rabbit, which was then euthanized. Postoperative complications for the remaining rabbits included superficial incisional dehiscence (LapOVE, 1/5; OVE, 2/6), subcutaneous emphysema (LapOVE, 1/5; OVE, 0/6), and seroma formation (LapOVE, 1/5; OVE, 0/6). CONCLUSIONS AND CLINICAL RELEVANCE Surgery time for LapOVE was twice that of OVE, and LapOVE resulted in unique complications in rabbits. No evidence of a reduction in pain or faster return to baseline physiologic status was found for LapOVE. Further evaluation of LapOVE in rabbits is warranted, with modification to techniques used in this study or a larger sample size.

An adult female Sambar Deer (Cervus unicolor) at Wildlife Conservation Centre, Sungkai, Perak was found dead in the paddock after abortion. The dead foetus was found on the paddock the day before this incident. The workers at the conservation centre also reported that the doe was attacked few times prior to death by a bull of the same group. The paddock in the Sungkai Conservation Centre was under construction and it was suspected that the noise from heavy machiner y and animals being transferred into different paddocks caused further stress to the affected doe which led to abortion and death. Post-mortem lesions showed generalised congestion and haemorrhage of all vital organs including liver, heart, lungs, kidneys and spleen. Histopathology revealed all organs have evidence of generalised congestion. Cause of death in this case is failure of the body system due to generalised congestion of the vital organs due to stress factor.

1991
Gallivan, G.J. | Viel, L. | Baird, J.D. | McDonell, W.N.
Pulmonary function tests were performed on seven adult dairy cows with an expanded tung field (ExLF) and the results were compared to the values from seven cows with normal lung fields. The cows with ExLF had an increased functional residual capacity (FRC) and end-tidal N2 concentration of the final breath of the multiple-breath N2 washout (FET(N2),fb), and an abnormal distribution of ventilation. The measurements of ventilation and gas exchange and pulmonary mechanics did not differ between the two groups. Postmortem examination of the lungs of five of the cows in each group indicated the cows with ExLF had a bronchiolitis with varying degrees of goblet cell hyperplasia, epithelial cell hyperplasia and metaplasia, smooth muscle hypertrophy, inflammatory cell infiltrate, vascular thickening, peribronchiolar fibrosis, and a mild overinflation of the lung. A histopathological score, based on the preceding indices and bronchus-associated lymphoid tissue, was correlated with FRC, FET(N2),fb, the lung clearance index and pulmonary resistance. There were no correlations between the histopathological score and any of the measures of ventilation and gas exchange.
