Ear mange is an annoying problem for all animal breeders including rabbit's breeders. This study aimed to compare the efficacy of moxidectin and 10% propolis ointment on rabbits infested with Psoroptes cuniculi with especial reference to some related biochemical parameters diagnostic and prognostic value. For this purpose, a total of thirty-two rabbits: 8 non-infested rabbits (control group (CG) and 24 naturally infested rabbits were used. Infested rabbits were equally divided into three groups: 1st group remained without treatment (diseased group (DG)), 2nd group was treated with moxidectin ((0.2 mg/kg body weight) S/C (MG)). Propolis ointment (10%) was applied topically to rabbits of the 3rd group (PG) once daily. Ear scrapes and blood samples were taken on 0, 7, 14 and 21 days. The ear scraping was examined microscopically and the biochemical parameters were estimated and statistically analyzed. The results cleared that moxidectin achieved the complete healing (14th day) faster than propolis ointment (21st day), but MG suffered from a significant (P<0.05) hypoalbuminemia, increased liver and kidney function tests and cortisol levels when compared to PG. Liver and kidney function tests and cortisol yielded good values of the area under the curve, sensitivity%, specificity%, likelihood ratio, PPV%, NPV%, accuracy rate% in DG, MG (except creatinine) and PG. The study concluded that propolis had a prominent antipsoroptic effect without inducing hepatic or renal toxicity. Liver and kidney function tests and cortisol may be useful markers for rabbit mange diagnosis and prognosis and following up its treatment.

The aim of the present work is to study immunomodulating effect of gentamicin on broiler chickens vaccinated against Newcastle virus at 18 days and challenged with a virulent strain of ND at the 30 th day of age. Three groups of one day old Hubbard chicks each of 30 birds

The aim of the present work was to study the effect of two anticoccidial drugs namely diclazuril and semduramicin on the immune response of briolers. Birds were divided into three equal groups, each of 50 chicks. The 1 st .group received semduramicin (25 ppm). The 2 nd group received diclazuril (1ppm) and 3 rd group received only basal ration (control). All groups were vaccinated against Newcastle virus at 18 days and were challenged with a virulent strain of ND at the 21th day of age. Blood samples were collected from

The aim of the present work was to study the incidence of ivermectin residues in cattle meat in some areas at Kafer Elshekh Governorate. Also, the stability of this drug for different methods of conventional cooking (grilling, boiling and frying• Forty random cattle meat samples were collected from butcher shops in some areas at Kafer Elshekh governorate. Each sample was kept in separate sterile plastic bag and transferred to the lab in an insulated ice box for detection of their content of ivermectin residues using high performance liquid chromatography (HPLC) technique. The results indicated that 7.50% of the collected meat samples were found to contain ivermectin residue below the maximum residual limits. Also, it could be stated that conventional cooking couldn't be considered a safeguard against ingestion of residues of ivermectin where grilling, boiling and frying of the positive samples induced loses of 25•4%, 30•9 % and 23•6 % of ivermectin residues content respectively•
