Background: Cardiac disorders are the second most common disorders after cancer in dogs. Cardiac disorders are often fatal and/or silent killers in canines. In our country, in the majority of cardiovascular disorders, there is a frequent omission by clinician and client due to lack of awareness. However, any cardiac abnormality requires to be dealt with top priority to avoid morbidity and mortality in the dog population. The present study was aimed to know the electrocardiographic interpretations of cardiac disorders in dogs.
Methods: For this purpose, a total of 5110 dogs presented at Veterinary Clinical Complex, College of Veterinary Science and Animal Husbandry, Nanaji Deshmukh Veterinary Science University, Jabalpur, Madhya Pradesh, from November 2019 to June 2020 were screened. Among them, 137 dogs had clinical signs about cardiac disorders were subjected to thorough electrocardiographic recordings for interpretations of various cardiac conduction anomalies.
Result: Electrocardiography revealed various types of supraventricular and ventricular abnormalities. Among supraventricular disorders maximally wandering pacemaker (30.60%) was recorded followed by atrial fibrillation (22.58%), left atrial enlargement (8.06%) and sinus arrest (4.84%) in dogs. Among ventricular abnormalities; left ventricular enlargement, right ventricular enlargement and biventricular enlargement (i.e. 41.67%, 37.49% and 8.33%, respectively) were commonly diagnosed.
In the present study cows were screened 75 th day before expected date of calving by using MCMT, somatic cell count and pH. Then positive cows for subclinical mastitis were randomly divided into four groups, each comprising of 8 cows. MCMT, SCC and pH evaluation were performed in milk samples of all the 32 cattle under therapy on day 0 pre-treatment (at drying off) and 7, 45 and 90 post treatment (after calving). The result revealed significant decrease in SCC and MCMT grading in all the treatment groups that reached towards normal after treatment. On the basis of MCMT grading and drastic reduction in SCC on 7 th , 45 th and 90 th day post treatment in animals of group T3 (Ceftiofur hydrochloride and Internal Teat sealant) revealed highest recovery followed by T1 (Ceftiofur hydrochloride) and T2 (Teat sealant (Bismuth subnitrate) alone.
The present study was undertaken to examine the incidence of Eimeria species infection in Murrah buffalo calves and evaluate the therapeutic management of the disease. In November 2019, 9 to 10 buffaloes calves up to 3 months of age showed symptoms of diarrhoea, loss of appetite, and poor weight gain at an organised dairy farm. Based on history, faecal samples were collected from 20 buffaloes calves and subjected to standard qualitative coprological examination and quantitative analysis using a modified McMaster technique. Out of 20 faecal samples, 90% were positive for coccidia oocysts. Among positive samples, 11% were heavily infected and 16% had a moderate level of infection of Eimeria spp. Six species of Eimeria were identified, E. bareillyi was the most often encountered species, accounting for 37.39%, followed by E. bovis (22.76%), E. zuernii (14.63%), E. ellipsoidalis (13.82%), E. canadensis (13.82%), and E. cylindrica (6.50%). Blood examination of mild and severely affected calves revealed a decrease in the mean values of hemoglobulin, total erythrocyte count, total leucocyte count, platelets and an increase in monocytes as compared with healthy calves. The affected calves were treated with combination of Sulphadiazine and Trimethoprim (Biotrim IV injection) along with supportive treatment for five successive days. All the affected animals responded well to the treatment and showed marked reduction in clinical symptoms as well as oocyst output.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
