The present study was conducted to evaluate 16 crosses between 4 breeds of rabbits from a physiological point of view. The breeds tested were Baladi Red (BR), Chinchilla Giganta (ChG), French Giant Papillon (FGP) and Simenwar (S). A total number of 6144 blood samples were collected to detect the effect of crossing, age of kits, month of kindling and sex effects. The traits evaluated were: haematological parameters; red blood cell count (RBCs), haemoglobin concentration (Hb), haematocrit value (Ht%), biochemical parameters of plasma; total protein (TP), albumin (Alb), globulin concentration (Glo), albumin/globulin ratio (Alb/Glo) and triglycerides (TG). BR or its crosses, using BR sires or BR dams, showed the highest value of RBCs, Hb and Ht%. Crossbred rabbits obtained from mating BR and FGP rabbits had the highest Glo values. Rabbits which were born in May-June months had the highest values of TP and its fractions (Alb and Glo). Age of kits had a highly significant effect (P<0.001) on RBCs, Hb, Ht%, TP and TG. Moreover, Glo and Alb/Glo ratio (P<0.01) and Alb (P<0.05) were also significantly affected. Sex had no significant effect on all studied parameters. Significant positive correlations were found between TP and each final body weight, total weight gain, total feed intake, carcass weight and dressing percentage, while significant negative correlation was found with feed conversion.

Camel mastitis is indeed a serious problem that can have significant impacts on animal health and production as well as pose a potential public health hazard. This work aimed to identify the bacterial species responsible for camel mastitis and evaluate the associated immunological and clinicopathological alterations in infected camels. Raw milk and blood samples were collected from 40 apparently healthy she-camels, and 40 she-camels suffered from clinical mastitis (CMG). Milk samples were subjected to bacteriological examination. Serum immunological, biochemical, and hematological parameters were estimated and statistically analyzed. Similar bacterial species were obtained from the two groups with different isolation rates.Staphylococcus epidermidis and Escherichia coliwere the dominant species in the apparently healthy group, whilePseudomonas aeruginosaandBacillus cereus were the dominant species in CMG. A significant (p < 0.05) elevation of the pro-inflammatory cytokines, acute phase proteins (APPs), free radicals, total protein, Glob, kidney and liver function tests, and triglyceride concentrations were detected in CMG, and a significant (p < 0.05) decrease in the anti-inflammatory cytokine, antioxidants, Alb, glucose, and T/LDL/HDL-cholesterol concentrations was observed in CMG. Microcytic hypochromic anemia with hypoferremia, hypotransferrinemia, hyperferritinemia, and neutrophilic leukocytosis was depicted in CMG. The estimated pro-inflammatory cytokines, APPs, and total antioxidant capacity (TAC) yielded high sensitivity and specificity, but the highest likelihood ratio was for TAC, fibrinogen (Fb), and ferritin, and the highest percentages of increase were for IL-1α and IL-1β. The study emphasizes the importance of hygienic preventive measures to control camel mastitis and the importance of supportive treatment to reverse the hemato-biochemicaland iron profile changes that result from the immune response in mastitic she-camels. TAC, Fb, ferritin, IL-1α, and IL-1β are good biomarkers for camel mastitis.

Background: Ovine mange is a highly transmissible skin condition that typically results in significant economic losses. Aim: This research explored the clinicopathological alterations associated with mange in Barki sheep and evaluated the impact of integrating probiotics (ZAD) into the treatment protocol. Additionally, the study proposed diagnostic markers and indicators for assessing treatment prognosis. Method: Twenty healthy lambs (control group (CG)) and twenty lambs suffered from mange symptoms (confirmed by skin scrapings) in the diseased group (DG). DG was divided into two groups: the traditional group (TG) was injected once with 1ml/50 kg ivermectin 1% (Promectine, Invesa) subcutaneously injected + topical Zinc ointment, and the ZAD Group (ZG): received the same treatment + 5 ml/ head of ZAD orally, repeated daily for 3 weeks. Skin scraping was repeated weekly until complete curing in both groups. Blood samples were collected from CG, DG (before treatment), and TG and ZG (after recovery). Results: DG (compared to CG) showed a significant (P<0.05) innate immune response with hypercortisolemia and hypoinsulinemia, microcytic hypochromic anemia with leukocytosis and lymphocytopenia, hypoglycemia, hypoalbuminemia, hyperglobulinemia, hyperlipidemia, elevated liver and kidney function tests, decreased minerals and electrolytes, and hypozincemia. After treatment, the clinical symptoms and lesions completely recovered, and most of the estimated parameters reobtain their physiological ranges in TG and ZG on the 21st day. ZAD did not significantly impact the recovery or regression of lesions, but it markedly improved the diseased animals` body weights and serum glucose in ZG (compared to CG and TG). Total antioxidant capacity (TAC), interleukin-1β (IL-1β), and ferritin had the highest likelihood ratios among the estimated markers. Conclusion: Ovine scabies can lead to systemic and clinicopathological changes, necessitating careful monitoring and intervention. Adding ZAD to the treatment of mangy sheep might help enhance their body weights and serum glucose levels, but it does not affect the healing or reduction of lesions. TAC and IL-1β serve as dependable indicators for diagnosing ovine scabies, whereas TAC and ferritin are valuable for evaluating treatment effectiveness.

The objective of the study was to assess the effect of A,D3,E (I/M) and oregano oil extract 15% on some clinicopathological parameters during lamb bacterial enteritis treatment. Sixty Barki lambs, 20 apparently healthy (control group) and, 40 suffered from bacterial enteritis [enteric group (EG)], were subdivided into four treated groups (TGs): antibiotic group (AG), antibiotic + A,D3,E group (A + A,D3,E), antibiotic + oregano oil (AOG), and oregano group (OG). Fecal swabs were collected from EG then aseptically cultured, isolated, phenotypically identified, genotypically confirmed, and sequenced by PCR 16srRNA. Paper disk diffusion test was used for estimation of oregano oil extract 15% antibacterial activity. After blood sample aspiration from all animals, they were clinicopathologically and statistically analyzed. Escherichia coli, followed by Salmonella species and then Klebsiella species, was the main causative agents of lamb diarrhea and were susceptible to oregano oil extract 15%. A + A,D3,E and AOG showed significant (p < 0.05) enhancement of some clinicopathological parameters more than AG or OG. Matrix metalloproteinases (MMP-2 and MMP-9) and total antioxidant capacity (TAC), yielded area under the curve, sensitivity, negative predictive value as 1, 100% and 100% respectively, were determined in both EG and TGs. Oregano oil extract 15% has good antibacterial properties against enteric bacteria in vitro and in vivo. The combination between antibiotic and antioxidant vitamins or oregano plant extract of 15% has a good impact on some clinicopathological alterations in lamb bacterial enteritis treatment. TAC, MMP-9, and MMP-2 may be good markers for the disease and its treatment follow-up.

| Recently, antioxidant vitamins were prescribed in different treatment and prophylactic programs for human and animal. Unfortunately, few studies investigated their concentrations in different sheep diseases. So, this paper aimed to assess the antioxidant vitamins (E, A, D 3 and C) levels in some sheep physiological and pathological conditions. For this purpose, 200 barki ewes were divided into control group, inflammatory diseases groups (pneumonic group, arthritic group, enteric group), late pregnant groups (normal late pregnant group, pregnancy toxemia group), postpartum groups (normal postpartum group, endometric group, mastitic group and non-inflammatory postpartum disorders group). Blood samples were collected from all ewes and vitamins concentrations were estimated in all groups. The results of this work demonstrated a significant ( P< 0.05 ) decrease in vitamin E, A, D 3 and C concentrations in inflammatory diseases groups , late pregnant groups and postpartum groups . Conclusion: antioxidant hypovitaminosis partially participate in different ovine diseases pathogenesis and complications and their supplement for healthy and diseased animals is strongly recommended.

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.
