Twenty buffalo heifers of the Murrah breed, aged six to eight months, were randomly assigned to four groups, with five replicates each, to be adapted to levels of 20%, 40%, 60%, and 80% of concentrate in the diet, composed of sugarcane (bulk) and concentrated feed based on wheat, corn, and soybean meal. The experimental diets were constituted in the proportion “bulk: concentrate”, based on dry matter, of “80:20” (Treatment 1), “60:40” (Treatment 2), “40:60” (Treatment 3), and “20:80” (Treatment 4). Biomarkers were evaluated for energy, protein, mineral, and endocrine profiles, as well as enzymatic activity. A positive linear effect was observed for Final Body Weight. In the energy profile, there was a positive linear effect for total cholesterol and HDL cholesterol and a quadratic effect for plasma glucose. In the protein profile, a quadratic effect was observed for the urea: creatinine ratio and a positive linear effect for total protein and albumin. For the enzymatic activity, only the variable gamma-glutamyltransferase presented a quadratic effect. In the mineral profile, a quadratic effect was observed for calcium levels and a positive linear effect for phosphorus levels and negative for chlorine levels. In the endocrine profile, no statistical differences were observed. Diet with until 80% of concentrate does not negatively influence biochemical parameters that represent the profile of energy, protein, mineral and thyroid hormones for growing buffalo heifers and favors the performance of the animals.","PeriodicalId":61886,"journal":{"name":"兽医学(英文)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70689545","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}

Ultrasound equipment allows estimating the viability and size of the embryo during early gestation. With the aim of assessing age and viability of Bos indicus embryos between 24 and 35 days of gestation, 55 cows were divided into 4 clusters. These clusters were conformed according to the first day that an echogenic structure was seen inside the embryonic vesicle (Group 1: day 24, Group 2: day 26, Group 3: day 27 and Group 4: day 28). The age of the embryos was estimated from the date of AI. Three progressive serial measurements of their length were made within 2 to 5 days. With a model GEE (Generalized Estimating Equations), the effect of days was evaluated to compare the second measurement with the first one and the former with the third observation. No differences in the size of the embryos were observed between the first evaluation (24 days) and the second (28 days) (P = 0.387). Also, simple linear regression analysis found a positive linear association between the size of the embryo and gestation days (R2 = 0.593) with an average growth of 0.078 cm per day (P = 0.001). In conclusion, the variation between measurements at a given time does not allow estimating with precision the exact day of gestation. Nonetheless, serial measurements are useful to estimate the healthy growth of the embryo from day 26 of gestation.","PeriodicalId":61886,"journal":{"name":"兽医学(英文)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46242816","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}

The objectives of this study were to evaluate the in vivo efficacy and safety of a new ear cleanser, Sonotix® against EpiOtic® Advanced for the management of canine otitis externa. Eighteen clients owned dogs with a diagnosis of erythemato-ceruminous or purulent otitis externa were prospectively included and randomized to two treatment group: EpiOtic® Advanced and Sonotix®. Cytology and video-otoscopic examination (erythema, amount of cerumen and thickness and surface of ear canal covered by cerumen) of all affected ears were done at D0, both before (T0) and 30 minutes (T0 + 30 min) after ear cleaning. Then an ear medication was applied (Aurizon®, Vetoquinol). Owners were instructed to clean affected ears daily and apply the ear medication 30 minutes later for 5 days (D1-D5). Dogs were seen again at D6 for cytology and video-otoscopic examination. At T0, no significant differences were found between both ear cleansers groups regarding macroscopic and microscopic scorings. At T0 + 30 min and D6 cytological and video-otoscopic scores were significantly decreased (Wilcoxon test; p < 0.01) compared to baseline in both groups. However, the cleaning activity of Sonotix® was statistically superior to Epiotic® as evidenced by the median global scores of video-otoscopic examination at T0 + 30 min (Mann Whitney Test, p < 0.01). Effective ear cleaning is an essential part of any treatment scheme because it favours the contact between the ointment and the lining ear epidermis and speeds resolution by the removal of cerumen, microbial organisms and cellular debris. In our study, the important reductions in yeast, cocci, and rod-shaped organism counts were demonstrated in smears at T0 + 30 min and D6 in both groups. Video-otoscopic examination performed 30 minutes after ear cleaning suggests that Sonotix® seems to be more effective in removing cerumen than EpiOtic® Advanced.","PeriodicalId":61886,"journal":{"name":"兽医学(英文)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45842585","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}

TB is endemic in India and has a worldwide prevalence, therefore, needing early diagnostic technique for the eradication of TB globally. Currently, compared to the eradication programme of TB in Medical sector, Veterinary sector is lagging behind though TB is one of the major zoonotic diseases prevalent in dairy animals and wildlife in India. With the “End TB” strategy by WHO in human, parallel measures for early diagnosis and culling has to be followed in case of animals for an overall successful eradication programme. The objective of this study is diagnosis of TB in cattle and buffaloes by using the cell-mediated immune response tests, i.e. Comparative Intradermal Tuberculin Test (CITT) and Interferon gamma (IFN-γ) assay, and Polymerase Chain Reaction (PCR) targeting esxB gene (CFP-10 protein) and to compare their diagnostic capabilities. This study was carried out in 202 dairy cattle and buffaloes from an organized dairy farm, where almost all of the animals appeared clinically healthy. We found that, the combined use of both CITT and IFN-γ assay lead to more accurate diagnosis of TB, although IFN-γ assay was more specific than CITT. However, esxB PCR showed almost similar sensitivity to IFN-γ assay and may be used as a fast alternative method for the diagnosis of bovine TB from blood samples.","PeriodicalId":61886,"journal":{"name":"兽医学(英文)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45103141","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}

Design: Prospective case series. Animals: 60 client-owned horses with a history of nephrosplenic entrapment. Procedures: The nephrosplenic space was closed under direct visualization through a specifically designed LED powered Single Port Trocar in standing sedated horses having experienced recurrence or previous surgical correction of a nephrosplenic entrapment. Obliteration of the space was performed in a cranial to caudal direction in a simple continuous fashion. Time required for suturing the nephrosplenic space, as well as per and post-operative complications were recorded. Clients and referring veterinarians were asked to communicate any complication that occurred after discharge. Results: Surgical time ranged from 23 to 45 min. No complication except for self-limited spleen capsule bleeding occurred during the procedure. Minor wound discharge was noted in 2 cases, and another 2 horses developed post-surgical sweating patches close to the incision. All horses were allowed to progressively resume exercise, starting 1 month post discharge from the hospital. Cosmetic results were considered satisfactory and no recurrence of left dorsal displacement of the colon was reported post-surgery.
