The rest of the animals were emaciated and showed various degree of debility. Studying the clinical, haematological and some trace elements status in blood serum of these camels were the main objectives of this study. Clinical examination of the emaciated camels revealed: weakness and paleness of the mucous membranes, some camels showed disappearance of the hump, atrophy of the thigh muscles and depletion of the sub-cutaneous fat, others showed alopecia, scales, keratinization and wounds of the skin and 12 camels were suffering from chronic diarrhoea. Clinical signs and laboratory findings of blood film and skin scraping revealed that 20 camels were suffering from trypanosomiasis (10 camels in the New Valley and 10 camels in Assiut Governorates), 6 camels suffering from <em>mange </em><em>mit</em><em>e</em><em>, </em>9 camels suffering from <em>trypanosoma </em><em>evansi </em>and <em>mange </em><em>m</em><em>i</em><em>t</em><em>e </em>and 12 camels suffering from chronic diarrhoea, emaciation and weakness. There were a highly significant decrease in the blood serum levels of copper in all the examined emaciated camels in the New Valley and Assiut Governorates. Blood serum levels of iron, zinc and manganese in camels in the New Valley were not affected however the levels of iron and zinc were significantly decreased and the level of manganese was not changed in the blood serum of emaciated camels reared in Assiut Governorate. The blood serum levels of iron, zinc
<strong>and </strong><strong>ma</strong><strong>nganese </strong>in healthy camels reared in Assiut Governorate were statistically lower than that of camels raised in the New Valley Governorate. This may be attributed to the high levels of these elements in the soils of the New Valley zones. Regarding the haematological invest<span style="text-decoration: underline;">ig</span>ation there were a <strong>decrease </strong>in the total count of erythrocytes, haemoglobin, PCV and MCHC, no changes in the MCV and MCH values and highly significant increase in the total count of leucocytes.

A total of 48 corpora lutea were dissected from ovaries obtained from local abattoir and classified according to physico-anatomy to developing, fully developed and regressing corpora lutea. In regressing corpora lutea, although, the total LPO production was higher the NO production was lower than in developing or fully developed CLs. Moreover, LPO production was negatively correlated with both SOD and serum P4 levels, which were significant in fully developed or in regressing CLS. Superoxide dismutase activity and glutathione content were significantly higher in fully developed corpora lutea. SOD activity was significantly positively correlated with serum P4 levels in developing or fully developed CLs. Vitamin E content tend to be higher in regressing CL than in other stages of development of CL. However, a marked increase of total lipid content was observed in regressing CL than in developing or fully developed CL, the cholesterol levels was unchanged. It's concluded that changes in lipid peroxide and nitric oxide production and antioxidant activities is a dynamic and regulated process, which could play an important role in regulating luteal function during estrous cycle in buffalo-cows.https://avmj.journals.ekb.eg/article_183186_9c292f68a5571501df5e2bb09cf26b0b.pdfAssiut University, Faculty of Veterinary MedicineAssiut Veterinary Medical Journal1012-597339.17719980401IMMUNE STATUS IN HORSES NATURALLY INFESTED WITH INTESTINAL PARASITES AND MANGE MITE22424118318710.21608/avmj.1998.183187ENM.N.Abd-El-SalamDept. of Animal Medicine

Mild and moderate intestinal infestation showed no significant difference in serum total protein, although there was a low A/G ratio in moderate infestation. There was non-significant difference in alpha-1 and alpha-2 globulins between diseased and apparently healthy horses, However, there was non-significant increase in beta-1 and beta-2 globulins and significant increase in gamma globulin in horses with heavy intestinal infestation and with mange mite infection. A significant difference was found in serum levels of vitamin E between diseased and healthy control groups, There was a positive correlation between the drop of serum levels of vitamin E and the degree of intestinal parasitic infestation. A correlation was also found between serum levels of vitamin E and serum levels of gamm globulins. It can be concluded that the infection with intestinal parasites and mange mite, specially when it is heavy and prolonged for long time, has a marked stress effect on body immune efficiency.https://avmj.journals.ekb.eg/article_183187_528d989dafcaf559b47d10773963c063.pdfAssiut University, Faculty of Veterinary MedicineAssiut Veterinary Medical Journal1012-597339.17719980401FEED INTAKE AND DIGESTIBILITY OF NUTRIENTS IN RATIONS, WITH SEVERAL FEED COMBINATIONS, BY TILAPIA FISH (0.niloticus)24225718318810.21608/avmj.1998.183188ENA.N.SayedDept. of Animal Hygiene

HafezJournal Article19980329The digestion coefficient of several different combinations were determined in this study by tilapia <em>(</em><em>O</em><em>.</em><em>niloticus</em><em>) </em>fish in order to extract the proximate figures for the d<span style="text-decoration: underline;">ig</span>estibility of different nutrients (organic matter, protein, fat, fibre, nitrogen-free extract and ener<span style="text-decoration: underline;">g</span>y). Fourteen d<span style="text-decoration: underline;">ig</span>estion experiments were performed using 14 experimental rations which formulated from different feedingstuffs (fish, meat, poultry by-products, earthworm, soybean, cottonseed and poultry manure meals, corn, wheat bran, middlings and berseem hay). Fish were fed twice daily to satiation and the experiments were lasted for one month. Faecal samples were collected by syphoning and
tion of the faecal matter from the aquarium. The amount of feed consumption for fish satiation depends on the quality of diets according to fibre percentage or imbibition ability of water. The d<span style="text-decoration: underline;">i</span>gestibility of crude protein over a range of 80-91% (x =86%) by tilapia which depends on the source of protein, and the rations with high percent<span style="text-decoration: underline;">ag</span>es of fish meal and soybean meal had the highest d<span style="text-decoration: underline;">ig</span>estion coefficients. The d<span style="text-decoration: underline;">ig</span>estion coefficient for fat ranged from 83 to 85% (X=84%), and the diets containing h<span style="text-decoration: underline;">ig</span>h levels of fat gave h<span style="text-decoration: underline;">i</span>gh values for d<span style="text-decoration: underline;">i</span>gestibility of fat. For carbohydrates, the digestion coefficient of nitrogen-free extract ranged from 73% to 87% ( =78%), while for fibre from 71 to 85% (X=79%), and diets which contained cottonseed meal, wheat middlings and berseem hay had the lower carbohydrates d<span style="text-decoration: underline;">i</span>gestibility. The d<span style="text-decoration: underline;">i</span>gestion coefficient for energy ranged from 61 to 71% (x =66%) and the ration contained fish oil gave high values. It could be concluded that, these average figures can be used as a guide in the formulating diets to satisfy tilapia fish needs.https://avmj.journals.ekb.eg/article_183188_d299e041b827efdd7895fb7a75fd2d73.pdfAssiut University, Faculty of Veterinary MedicineAssiut Veterinary Medical Journal1012-597339.17719980401RESIDUES OF QUINOLONE GROUP OF ANTIBIOTICS IN TABLE EGGS (*) (*) part of thesis submitted to Fac.

The MICS of enrofloxacin using E. Coli, P.fluorecens ,K pneumoniae and B. subtilus as test organisms were 0.022, 0.12, 0.054 and 0.096 ug<em>/</em>ml while MICS OF flumequine using the same test organismes were 0.04, 0.17, 0.096 and. 022ug<em>/</em>ml respectively. Enrofloxacin residues could be detected at the 2<span style="text-decoration: underline;">n</span>d day of oral adminstration and last for 2 days in albumen, and 4 days after last dose of application, while flumequine last for 3 days in albumen and 2 days in yolk after the last dose of application. The inhibitory substances in the examined egg samples perchased from Alexandria, Behera and Kafr El-Sheikh governorates were, 70, 62 and 24%,78,82 and 16% and 84,64 and 48% of brown, white and Balady table eggs respectively.https://avmj.journals.ekb.eg/article_183189_55920a6635ae05b5e69b426384a6e572.pdf
