Objectives: Demodicosis is a vital skin problem in dogs. The present study has determined the prevalence and associated risk factors of demodicosis in dogs and the response to treatment. Materials and Methods: A total of 100 skin scrapings were collected from dogs having dermatological lesions brought to the Teaching and Training Pet Hospital and Research Center of Chattogram Veterinary and Animal Sciences University for treatment purpose. The collected scrapings were dissolved in 10% potassium hydroxide to detect mites through microscopic examination. Various risk factors like breed, age, sex, hair type, health status, and management system (indoor and outdoor) were analyzed using the logistic regression model. Positive cases were treated with oral ivermectin (Scabo ® ; at 0.6 mg/kg/day) along with amitraz 12.5% (Ridd ® ) diluted to 0.05% for rubbing on the body after bathing with chlorhexidine shampoo (PetHex ® ). Clavulanate amoxicillin (Moxaclav ® ) and omega-3 fatty acids (OMG-3 ® ) were also suggested to prevent secondary bacterial infection and to maintain skin and hair coat integrity. The recovery rate was observed every 2–4 weeks of treatment upto 11–13 weeks. Results: The overall prevalence of demodicosis was recorded as 27%. Hair type, health status, and management system were significantly ( p < 0.05) associated with the occurrence of demodicosis in dogs. Following treatment, the first negative skin scraping for mite was noticed at 8–10 weeks of treatment, and in all cases, clinical signs completely disappeared at 80–90 days of treatment. Conclusion: A good percentage of the dogs having dermatological lesions was determined as demodicosis. Long-term oral ivermectin and topical amitraz, an oral antibiotic, and nutritional therapy are effective against canine demodicosis. Keeping long-haired dogs with good body condition and indoor management is highly suggestive of preventing and controlling the disease.
Caponization is generally supposed to affect the growth performance, carcass composition, and meat quality of male chickens. The present research work was conducted on 90-day-old Fayoumi male birds at Shahedul Alam Quaderi Teaching Veterinary Hospital Chattogram Veterinary and Animal Sciences University during the period from August 2018 to October 2018. The objectives of the study were to evaluate the effects of caponization on surgical efficacy and complications, growth performance, and blood parameter changes (CBC, serum protein, and glucose). The experiment was divided into two groups, an experimental group, and a control group with an equal number of birds (n = 10). Only the birds of the experimental group were caponized at the age of 90 days and reared for 62 days until they reached 152 days of age. Each bird in both groups was given equal care, feeding, water, and housing. Each bird was given a separate tag number for record-keeping. The present study revealed that 20% of birds died during surgery, and on the next day of surgery, 40% of birds were found to develop wind puff, and the average wound healing period was 6 days. The feed and water intake were slightly lower in the experimental group compared to the control group. There were no significant variations in body weight gain, feed, or water intake. Blood CBC (except PCV value and monocyte count), serum protein, and glucose levels were also not significantly changed between the two groups (p>0.05). But the present study revealed that caponization significantly decreases the PCV value of blood and significantly keeps the monocyte count stable with the age of poultry (p 0.05).
The present study was conducted to evaluate minimally invasive tube cystostomy technique in goats and calves suffering from obstructive urolithiasis having intact and ruptured urinary bladder. This clinical study was carried out on 84 clinical cases (61 goats and 23 calves) based on the history, clinical signs and physical examination along with common laboratory techniques at the Chittagong Veterinary and Animal Sciences University during January 2015-December 2016. Physical parameters like heart rate, respiratory rate, rectal temperature and dehydration status of animals were noted and corrected abnormality before surgery. Some cases had slightly higher haemoglobin (Hb), packed cell volume (PCV) and uric acid and epithelial casts in urine. The study revealed that abnormal calcium-phosphorus ratio was predisposing the animals to urolithiasis. It was found that young ruminants (3-5 months) were most commonly affected in both species. All affected animals were male in this study, in which calves were not castrated but in goats 95.08% animals were castrated. Rupture of bladder was more common in calves as compared to goats. Postoperatively all cases were administered with broad-spectrum antibiotic, anti-inflammatory agent and caliculolytic agents like ammonium chloride. Tube cystostomy with Foley's catheter was the most satisfactory technique for the management of obstructive urolithiasis in small ruminants. Postoperative complications were recorded only in four animals and remaining 80 animals had a normal recovery from tube cystostomy. Tube cystostomy is a simple, inexpensive and very effective procedure for the treatment of urolithiasis in ruminants.
