Following oral administration of albendazole of 0.25 mg/kg body weight and Vitamin E of 0.01 mg/kg body weight used for 21 successive days to broiler chicken, the experiment was done on fifteen broiler chickens divided into three groups: group one was non-treated, group two was treated with albendazole of 0.25 mg/kg body weight and group three was treated in combination with vitamin E of 0.01 mg/kg body weight. The blood sample and tissue were taken at the end of experiment 12 hrs after the last dose. The experimental result revealed that the significant decrease of liver enzymes caused by albendazole like serum Alanine Aminotransferase (ALP), Aspartate Aminotransferase (AST), Alkaline Phosphatase (ALT), when compared with the control group, the experimental result significant decrease in kidney parameters like urea creatinine level caused by albendazole and finally there was a significant increase in antioxidant enzymes activity like CAT, SOP, GPX and a significant decrease in MDA. Histopathology results in liver-treated animals with albendazole in combination with vitamin E showed dilated, congested Portal Blood Vessels (PBV, arrow), mild to moderate Biliary Proliferation (BP, arrow), portal Round Cells Aggregation (RCA, arrow), and focal Hepatocellular Degeneration (HCD, arrow). Histopathology results of kidney-treated animals with albendazole in combination with vitamin E showing a mild Per Tubular Edema (PTE arrow), focal Tubular Degeneration (TD arrow), Tubular Regeneration (TR, arrow), glomerular lobulation and atrophy (GL arrow), and beside interstitial cells aggregation (RCA arrow), H & EX 200. Therefore, vitamin E should be taken by albendazole to decrease its effect.","PeriodicalId":61886,"journal":{"name":"兽医学(英文)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70689573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has a complex chemical composition that varies with the harvest season, vegetation type, bee species, and geographical region. Thanks to its components, it has valuable biological properties such as antifungal, antibacterial, anticancer, antiviral, and immunomodulatory activity. For this study, a sample of propolis harvested in April 2019 was used, which came from a bee native to Mexico (Plebeia frontalis) in whose geographical environment there are seven other native species. Canine distemper virus is an RNA virus that causes a systemic infection with high fatality rates in guests without protective immunity. In this work, the antiviral effect of Plebeia frontalis propolis on canine distemper virus was tested, administering it one hour before and simultaneously to infection. The antiviral effect was evaluated by determining cellular viability with the MTT assay. The results obtained show that this propolis has a statistically significant antiviral effect on both treatments, although it is slightly better when applied one hour before viral infection, so we can recommend it as an antiviral treatment in both domestic animals and human beings. There are currently few studies of the antiviral effect of propolis, this being the first study of a melliponium propolis in veterinary medicine.","PeriodicalId":61886,"journal":{"name":"兽医学(英文)","volume":"10 1","pages":"207-218"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41760644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 13 small scale dual-purpose Bos indicus × Bos taurus operations were included in this experiment and they were classified according to their technological status as: high technological status (HT), medium technological status (MT) and low technological status (LT). Ninety-three mature cows were treated with either a CIDR (controlled internal drug release device) with estradiol benzoate (CIDR+EB) or alone (CIDR). At day 9 all animals received intravaginally a CIDR for nine days. At day 0, the CIDR was withdrawn and 24 hours later one dose of estradiol benzoate was administered to 51 cows (17 in HT, 17 in MT and 17 in LT), the remaining animals (n = 42) did not receive the estradiol benzoate administration (14 in HT, 13 in MT and 15 in LT). Comparisons were performed on serum progesterone concentrations after CIDR treatment. By day 7 after implant withdrawal, the proportion of cows that resume ovarian activity detected by progesterone concentration increased in all technological level farms, no statistical main effect was observed within technological level. By day 17 there was a significant main effect of technological level (P = 0.05) on the proportion of animal that resumed the estrous cycles, but neither a main effect of treatment (P = 0.97) nor an interaction between technological level and treatment (P = 0.98). Furthermore, technological level of the farm showed a tendency (P = 0.07) to affect that resume the estrous activity, and a significant effect of treatment was observed (P = 0.005) but no interaction between technological level and treatment. The proportion of cows that showed estrus was different across technological level (P = 0.02), the highest proportion of cows showing estrus regardless of treatment was in the HT: 90% (40% CIDR and 50% CIDR+EB), MT: 50% (13.3% CIDR and 36.7% CIDR+EB) and in the LT: 50% (18.8% CIDR and 31.3% CIDR+EB). In conclusion, the combination of a progestogen and estradiol benzoate resulted in a high proportion of cows that were induced to resume the ovarian activity and this treatment was particularly beneficial in the medium and low technological status of the farms.","PeriodicalId":61886,"journal":{"name":"兽医学(英文)","volume":"10 1","pages":"195-205"},"PeriodicalIF":0.0,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45794788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cold-therapy is commonly used as a preventative measure and treatment for acute tendon injuries, but only a few studies have evaluated the effect of cold-therapy on metacarpal temperatures in the horse. For this reason, this study has measured skin surface temperatures after moderate exercise and after application of cold-therapy, and additionally monitored the duration of any effects. Four horses were recruited into a semi blinded controlled study with repeated measurements that involved lunged exercise for 16 minutes at moderate intensity. Skin surface temperature was measured using a thermographic camera before and after lunging, and every 40 minutes for two hours post cold-therapy. Cold-therapy was applied using a Jacks Whirlpool Boot with ice-water immersion at a level just distal to the carpus for 20 minutes. The right leg was treated, and the left leg was used as an untreated control. The experiment was conducted twice on all four horses. Moderate exercise resulted in an increase in skin surface temperature of 10°C. Application of cold-therapy for 20 minutes resulted in a reduction in skin surface temperature by 14°C. The effect of cold-therapy persisted for at least 40 minutes post treatment. It is concluded that exercise leads to an increase in skin surface temperature which is counteracted by the application of cold-therapy. These findings would seem to indicate that cold-therapy can be used after exercise to counteract hyperthermia within the metacarpal region of the horse’s leg.","PeriodicalId":61886,"journal":{"name":"兽医学(英文)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42363458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clinical signs are nonspecific such as dehydration, hypovolemic shock, bradycardia, hypotension, emesis, diarrhea, among other clinical and laboratory changes, and can mimic other diseases, and because of this, the disease can go unnoticed by the veterinarian, increasing the mortality and morbidity of patients seen in emergency consultations. Despite being of low occurrence, hypoadrenocorticism is often underdiagnosed, and should be considered in the differential diagnosis in the presence of gastrointestinal clinical signs or hypovolemic shock, and low Sodium:Potassium ratio. The definitive diagnosis is based on the dosage of cortisol before and after the application of the adrenocorticotrophic hormone. Acute treatment consists of patient stabilization, and chronic includes replacement of glucocorticoids and mineralocorticoids. Prognosis is usually favorable if the diagnosis is early and the correct treatment is performed. This article is a review focusing on clinical signs, laboratory findings, diagnosis and treatment on canine hypoadrenocorticism, to increase the knowledge about the disease to veterinarians.","PeriodicalId":61886,"journal":{"name":"兽医学(英文)","volume":"10 1","pages":"164-172"},"PeriodicalIF":0.0,"publicationDate":"2020-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46031815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wild animals in zoological gardens can predominately affected by various gastro-intestinal parasites. This study was therefore, conducted to determine occurrence, identify types and assess seasonal variation of gastrointestinal parasites in captive animals at the Zoological garden of Haramaya University. The study involved a retrospective investigation of zoo records and fecal examinations. Twenty two fecal samples were collected in December, 2013 from all the animals in the garden and examined using concentration and fecal culture techniques. Sampling was repeated after four months in April, 2014 to assess seasonal variations of the parasites. The result from the retrospective study showed death of 21 animals in the last five years. Fecal examination confirmed presence of gastrointestinal parasites with an overall mean prevalence rate of 73.8%. A total of 9 parasite taxa were identified of which 6 (66.67%) and 4 (33.33%) were helminths and protozoa respectively. No Cestode and Trematode species were recovered. Trichuris spp., Toxocara spp., Strongyloides spp., Toxascaris leonine, Passalurus ambiguous and Ascaridia spp. were the helminth parasites observed in the garden. Entamoeba spp., Isospora spp. and Eimeria spp. were the protozoan parasites encountered. No remarkable seasonal variation in parasitic infection was noticed in the garden. The study revealed occurrence of gastrointestinal parasites in the zoological garden, most of which are zoonotic and hence future studies are needed to determine risks of cross-transmission.","PeriodicalId":61886,"journal":{"name":"兽医学(英文)","volume":"10 1","pages":"173-184"},"PeriodicalIF":0.0,"publicationDate":"2020-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44597069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
