| Cadmium (Cd), a toxic heavy metal, is often associated with the reproductive disorders of mammals. The edible bird’s nest (EBN) is a naturally occurring food product made from the saliva of swiftlet birds ( Aerodramus fuci-phagus & Aerodramus maximus ) in the form of a nest, and it has been consumed as healthy food or tonic for decades. This research aimed to study the possible protective effects of EBN against Cd toxicity in ovaries of Sprague Dawley rats. Thirty (30) female Sprague Dawley rats were assigned into five groups as follows: group 1-Negative control (NC) received distilled water; group 2-positive control (PC) administered with CdCl 2 , 5mg/kg BW; while groups EBN 1, EBN 2, and EBN 3 received CdCl 2 (5mg/kg BW) concurrently with graded concentrations of 60, 90 and 120 mg/kg BW of EBN, respectively. After four weeks of treatment, rats were euthanized to collect ovaries for histopathological studies using hematoxylin and eosin (H&E) stain. Expressions of vascular endothelial growth factor (VEGF) were analyzed through immunohistochemistry, and levels of superoxidase dismutase (SOD) were assessed using a SOD assay kit. Oral administration of CdCl 2 without EBN supplement resulted in significantly decreased (p<0.05) immunohistochemical expressions of VEGF in ovarian tissue and a decrease (p<0.05) in the activity of SOD. Moreover, ovarian histopathological changes, including follicular cysts and a significant increase (p<0.05) in the number of atretic follicles, while a decrease in the number of growing follicles was noted in Cd only treated group. Animals treated with CdCl 2 and EBN at three different dosages resulted in significantly increased (p<0.05) expressions of VEGF in ovarian tissues, low degenerative changes with normal histomorphology as well as significantly increased (p<0.05) SOD activity as compared to the PC group. Overall, the findings revealed that oral exposure to Cd at a dose rate of 5 mg/kg BW resulted in significant alterations in ovaries, as evidenced by a lower degree of VEGF expression along with reduced antioxidant activity and histomorphological changes. Meanwhile, EBN proved to exhibit a significant protective role against Cd toxicity in ovaries, possibly through its antioxidant effect.

| The current study aimed to investigate the bacteriological quality of the ready-to-eat (RTE) meat sandwiches prepared using the meat and treated ingredients viz., green salad and tahini sauce. Two hundred and forty samples of RTE meat sandwiches, vegetable salad, and tahini sauce were used in the study. The washing of vegetable salad for 10 min with water providing 50 ppm chlorine reduced (p < 0.05) the aerobic plate count (APC), Bacillus cereus (B. cereus) and Staphylococcus aureus (S. aureus) count. Similarly, addition of 1% garlic essential oil during formulation of tahini sauce reduced (p < 0.05) APC, B. cereus and S. aureus count. The counts in RTE meat sandwiches after using treated green salad and tahini sauce reduced (p < 0.05) APC count from (5.58 ± 1.21 and 6.54 ± 1.12) to (3.2 ± 0.22 and 4. 89 ± 0.31) log10CFU/g. The counts of B.cereus reduced (p < 0.05) from (2.98 ± 0.11 and 3.34 ± 0.15) to (<2 and 2. 49 ± 0.09) and S.aureus reduced (p < 0.05) from (3.18 ± 0.15 and 3.85 ± 0.13) to (<2 and 2. 87± 0.09) log10CFU/g. These results demonstrated that use of treated vegetable salad (washed by chlorine water) and tahini sauce (containing 1% garlic essential oil) in preparation of RTE meat sandwiches results the improved bacteriological quality of RTE meat sandwiches.

| Respiratory disorders have an economic effect on the dairy industry. The purpose of this study was to di-agnose cattle with respiratory problems, as well as to assess the nature of the lesions. A variety of practical approaches are used to examine respiratory disorders in cattle. The present study involved 55 cows of which 10 cows were clinically healthy and served as the control group. Cows were brought to the clinic for a number of complaints, including in-appetence, cough, dyspnea and nasal discharges. The total leucocytic counts, aspartate aminotransferase activities, and carbon dioxide tension were significantly higher in all diseased cows. The ultrasonographical examination of the lungs demonstrated several comet-tail artifacts in cows affected with pulmonary emphysema. Various degrees of pulmonary consolidation in bronchopneumonic cows were observed. Furthermore, cows with pleurisy showed anechoic pleural effusion with fibrin deposits and an irregular pleural surface. It is concluded that, hematological and biochemical findings are the key indicators of bovine health, and they are more expressive when correlated with the history, clinical symptoms, and ultrasonographic examination of cows with respiratory diseases.

worldwide (Earley et al ., Panciera and Abstract | A mortality outbreak in calves entered directly in a feedlot was reported. Mortality reached 24% in three days and morbidity was close to 60%. Animals arrived in feedlot three to four days before during the weekend and overwhelmed the expected entrance in 300%. Upon arrival the animals (among 7 to 8 months old, weighing 180-200kg) were received in a hallway employed to provisionally keep animals before assignment in a pen. The hallway was crowded to the point that the animals were restrained and many of them were unable to reach the sole drinker. No food was provided. The next Monday morning, animals were routinely processed (almost 60 h after) and assigned to a pen with drinkers and corn straw in feeders. However, that day many animals suddenly died (90), and many more (114), succumbed during the following two days (204/850=24%). The post mortem exams registered bronchopneumonia and abomasal ulcers, many of them (62 cases/204=30.4%) perforated causing peritonitis, in absence of severe bronchopneumonia. At first time, abomasal ulcers were considered a new syndrome with suspected clostridial disease or poisoning.

在世界范围内(Earley et al .， Panciera and Abstract bbb)曾报道过直接进入饲养场的小牛死亡暴发。三天内死亡率达到24%，发病率接近60%。动物在周末提前三到四天到达饲养场，超过预期入口的300%。抵达后，这些动物(7 - 8个月大，体重180-200公斤)被安置在走廊上，用于临时饲养动物，然后被分配到围栏里。走廊里挤满了人，动物们都被限制住了，很多动物都够不到唯一的饮酒者。没有提供食物。接下来的周一早上，动物们被常规处理(大约60小时后)，并被分配到一个有饮水器和喂食器的玉米秸秆的围栏里。然而，当天许多动物突然死亡(90只)，更多的(114只)在接下来的两天内死亡(204/850=24%)。尸检记录支气管肺炎和皱胃溃疡，其中许多(62例/204=30.4%)穿孔引起腹膜炎，没有严重的支气管肺炎。起初，皱胃溃疡被认为是一种疑为梭菌病或中毒的新综合征。一种可能的发病机制是，最初的无法忍受的应激导致溃疡，随后，饥饿迫使对秸秆秸秆的侵略性消耗引发瘤胃肿胀，伴有皱胃肿胀(或移位)，导致溃疡边缘缺血性坏死并穿孔和致命的腹膜炎。
