Authors: Jahan Nigar, Most Nushrat
Abstract: This study was conducted in the Rangpur district of Bangladesh to comprehensively
assess the factors influencing the reproductive performance of dairy cows, with a specific focus
on metestrous bleeding, parity, the timing of artificial insemination, age, breed, and repeat
breeding incidents. The study revealed some significant findings. Metestrous bleeding was
identified as a critical factor (P<0.00) significantly reducing the conception rate in dairy cows.
Parity was found to play a pivotal role (P<0.038) in determining conception rates, with heifers
exhibiting the highest fertility, while older cows experienced a decline in their reproductive
performance. The timing of artificial insemination (P<0.026) in relation to the onset of estrus
was very important, with insemination around 12-16 hours after onset estrus resulting in a
remarkable high conception rate. Moreover, age of cow was identified as influential factors,
with older cows at a higher risk of repeat breeding (P<0.048).2023-08-01T00:00:00ZA Successful Surgical Correction of Long Bone Fracture in Cat by Retrograde Intramedullary Pinning: 2 CasesMarma, Mongchai Singhttp://dspace.cvasu.ac.bd/jspui/handle/123456789/26552024-01-11T04:56:55Z2023-11-01T00:00:00ZTitle: A Successful Surgical Correction of Long Bone Fracture in Cat by Retrograde Intramedullary Pinning: 2 Cases
Authors: Marma, Mongchai Sing
Abstract: One of the most frequent clinical manifestations seen in feline patients is fractures. They are most frequently brought on by severe trauma, such as that which results from car accidents, high-rise syndrome, and dog bites. This study's objective was to retrospectively assess the frequency of feline long bone fractures that were successfully treated by intramedullary pinning. Intravenous anaesthetic was used to successfully treat a total of 2 occurrences of long bone fractures in cats of various breeds. A 14-month and 13-month indigenous male cats’ weight 4.2 kg and 3 kg were admitted to Teaching and Training Pet Hospital and Research Center, Purbachal, Dhaka with the history of injury in the long bone. The cat’s owners complain that they were hurt when they fell from the building's fifth and seventh floors. According to a clinical evaluation, the cats were hardly able to bear its weight, and the injured limb also displayed symptoms of discomfort, including limping and crepitation. Oblique mid diaphyseal complete fracture of left humerous (Figure-2) and Complete transverse proximal diaphyseal fracture of right femur (Figure-3) were found in radiographic examination. Patients were prepared aseptically, and standard surgical techniques were used along with the appropriate anaesthetic protocol to accomplish the surgery. Preanesthesia was provided by xylazine, while maintenance was provided by ketamine and diazepam. The surgical treatment of the presented fracture patients involved intramedullary pinning procedures. The cats were given systemic antibiotics, NSAIDs, and protective bandages after surgery. All cases were assessed using radiographs and the clinical effectiveness of the operated limbs. Information was obtained by calling the owner. At the 14th post-operative day, light weight bearing was noted. At the 45th postoperative day, full weight bearing, a functional limb outcome, and bone healing were noted. According to the results of the current case study, managing long bone fractures in cats can be done successfully using the retrograde IMP.2023-11-01T00:00:00ZISOLATION OF Streptococcus pneumoniae FROM A PNEUMONIC BUFFALO CALF ; CASE STUDYNanno, Minhazul Abedinhttp://dspace.cvasu.ac.bd/jspui/handle/123456789/26512024-01-09T12:11:17Z2014-03-01T00:00:00ZTitle: ISOLATION OF Streptococcus pneumoniae FROM A PNEUMONIC BUFFALO CALF ; CASE STUDY
Authors: Nanno, Minhazul Abedin
Abstract: Streptococcus pneumoniae infection was found in a 9 month aged buffalo calf having high fever (107° F), respiratory distress, mucopurulent nasal discharge with lateral recumbence lasting for 4 days. Ante mortem (Blood, edematous fluid) and Postmortem (eye-ball) sample was collected to conduct laboratory test for confirmation of causal agent. Actually the samples were collected for the purpose of isolation of Pasteurella multocida. The laboratory investigation revealed that the samples were bacteriologically positive & isolated organism were Streptococcus pneumoniae. It is proved that the buffalo calf infected by Streptococcus pneumoniae were subjected to death after 4 days of infection as the calf were treated by streptomycin, because the doctors treated it as gram-negative bacteria infection. This should be treated by broad-spectrum cephalosporins. It is emphasised that Streptococcus pneumonia may be considered to be and important respiratory pathogen which is responsible for death of buffalo calves and should be included in differential diagnosis of pulmonary diseases.2014-03-01T00:00:00ZPREVALENCE OF GASTOINTESTINAL PARASITIC INFESTATION OF PIGS IN CHITTAGONG DIVISION.Chakma, Florahttp://dspace.cvasu.ac.bd/jspui/handle/123456789/26432024-01-09T10:50:44Z2014-03-01T00:00:00ZTitle: PREVALENCE OF GASTOINTESTINAL PARASITIC INFESTATION OF PIGS IN CHITTAGONG DIVISION.
Authors: Chakma, Flora
Abstract: A cross-sectional study was undertaken to determine the prevalence of gastrointestinal parasitic infestation of pig in Chittagong division, Bangladesh. Fecal samples were collected randomly from 100 pigs between May and August 2013 and examined by routine coproscopical methods. The investigation revealed that the overall prevalence of gastrointestinal parasitic infections was 49% in the study population. Among different gastrointestinal parasitic infections, occurrence Oesophagostomum dentatum infection was the highest which was 17% in study population. The second most common parasitic infection was caused by Ascaris suum (11%) followed by Balantidium coli (7%). The lowest parasitic infections were also recorded for Hyostrongylus rubidus (4%) coccidian oocyst (4%) Trichuris suis (3%) and Strongyloides ransomni (3%). However, sex specific prevalence exposed that female pig showed more susceptibility to different gastrointestinal parasitic infections. Occurrence of Hyostrongylus rubidus and Balantidium coli were found predominant in female pigs than male pigs. On the other hand, occurrence of Ascaris suum was slightly higher in male group than female but it was not statistically significant (P>0.05). It could be stated that the current investigation was fresh of its type which will be acted as bench mark for further study in this area. Moreover, as it was a limited study where breed and topographical variation, seasonal pattern of the diseases were not included. Hence, it was suggested further extensive investigation on gastrointestinal parasitism to overcome the limitations of the current study which will assist to determine the important predictors related to such parasitic diseases.2014-03-01T00:00:00Z
