Authors: Akter, Sharmin
Abstract: The present study was conducted in 12 broiler farms of Mirsarai upazilla for the investigation of Infectious bursa disease (IBD) during May-June 2013.Necropsy of 50 broiler birds from different farm of Mirsarai upazilla was carried out to investigate the disease.7 Blood samples were collected & Haematological parameters were estimated. Among the gross changes, frequency of swollen bursa of fabricious were found mostly 20 and other lesions such as pus in bursa 15, haemorrhage in bursa 6, gelatinous fluid around the bursa 8, caseous mass in bursa 6, atrophied bursa 8.Other lesions in different organs also like as haemorrhage in the junction of proventriculus and gizzard 10 , mucous exudates in upper intestine 14, haemorrhage in the breast and thigh muscle 15. Striking destruction of lymphocytes in the bursal follicles were the major histopathological changes. Among the different farms, it was observed that the highest percentage of IBD infection was recorded in those farms where the flock size was >1500 in compare to flock size <1500. In these study, occurance of IBD (alone) was 36%, with ND 14%, with coccidiosis 30%, with colibacillosis 20%.
In these study, blood parameters are, highest Hb (mg/dl) 14 in sample 5, PCV 32% in sample 2, ESR 2, TEC(106/cu mm) 2.69 in sample 5, Lymphocyte 78 in sample 2, Monocyte 9 in sample 4, Heterophil 37 in sample 2, Eosinophil 11 in sample 4, Basophil 4 in sample 5.2014-03-01T00:00:00ZAntimicrobial Resistance Pattern of E. coli and Salmonella in Layer PoultryAmin, Khaled Binhttp://dspace.cvasu.ac.bd/jspui/handle/123456789/26492024-01-09T12:06:04Z2014-03-01T00:00:00ZTitle: Antimicrobial Resistance Pattern of E. coli and Salmonella in Layer Poultry
Authors: Amin, Khaled Bin
Abstract: E. coli and Salmonella resistance to the commonly used antimicrobials both in the public health and veterinary practice is one of the major threats of health care worldwide. The present study was undertaken to determine the antimicrobial resistance pattern of E. coli and Salmonella strains isolated from commercial layer from different layer farm under Chittagong district of Bangladesh, during the period September to December, 2012. Isolation and identification of E. coli and Salmonella was done by using different methods. Isolated E. coli and Salmonella were tested for resistance to 10 different antimicrobial agents, using disc diffusion method. The E. coli were found 100% resistant to Tetracycline, Ciprofloxacin, Enrofloxacin and Pefloxacin followed by Amoxycillin (84.62%), Kanamycin (69.24%), Colistin (63.75%), Doxycyclin (53.75%) and Neomycin (23.08%). Besides E. coli isolates show high sensitivity to Gentamycin (100%) and Neomycin (76.92%). Among the Salmonella isolates 100% were found resistant to Amoxycillin and Tetracycline followed by Enrofloxacin (87.5%), Ciproflpxacin (87.5%), Pefloxacin (87.5%), Doxycycline (50%), Colistin (50%) and Kanamycin (50%). Salmonella isolates showed high sensitivity (100%) to Gentamycin and Neomycin. The present study confirms the significant increase of the resistance level in E. coli and Salmonella isolated from poultry isolates. This is, probably, due to increase use of antibiotics as feed additives for growth promotion and prevention of disease, overlooking the proper withdrawal period, resistance transfer among different bacteria, and possible cross-resistance between antibiotics used in domestic animals and those used in human medicine.2014-03-01T00:00:00ZSurgical Management of a Fetal Mummification in Beetle Doe: A Case ReportRahman, Mohammad Anisurhttp://dspace.cvasu.ac.bd/jspui/handle/123456789/26352024-01-04T05:50:37Z2023-11-01T00:00:00ZTitle: Surgical Management of a Fetal Mummification in Beetle Doe: A Case Report
Authors: Rahman, Mohammad Anisur
Abstract: A 17-month-old beetle doe with dystocia having full-term pregnant was presented with a
history of vaginal discharge for 24 hours followed by anorexia, weakness, dullness and
depression at S.A. Quaderi Teaching Veterinary Hospital, Chattogram Veterinary and
Animal Sciences University. Clinical examination reveals 102.3°F body temperature, a
heart rate of 85/min and a respiration rate of 20/min. An X-ray was done to confirm the
fetal presentation. In per-vaginal examination showed the uterus contained a fetal mass
and that the cervix was fully dilated. Then mild traction was done with an obstetrical hook
and the mummified fetus was removed using finger guided embryotomy knife. The post operative care was done with an antibiotic, an analgesic, fluid therapy and mineral
supplement. Finally, the doe was cure2023-11-01T00:00:00ZANALYSIS OF PHYSICAL, BIOCHEMICAL AND HEMATOLOGICAL PARAMETERS OF RUMEN FLUID AND BLOOD IN DIGESTIVE DISORDERED GOATChakma, Jagrityhttp://dspace.cvasu.ac.bd/jspui/handle/123456789/26322024-01-04T04:53:52Z2013-06-01T00:00:00ZTitle: ANALYSIS OF PHYSICAL, BIOCHEMICAL AND HEMATOLOGICAL PARAMETERS OF RUMEN FLUID AND BLOOD IN DIGESTIVE DISORDERED GOAT
Authors: Chakma, Jagrity
Abstract: The study was carried out by collecting sample of rumen fluid and blood from the goat at SAQTVH, Chittagong during my internship programme. After collection of rumen fluid from diseased (anorexic, digestive disordered animal) different physiological parameters of rumen fluid (e.g. color, odor, consistency, pH) and motility and number of protozoa observed and studied in relation with different digestive disorder of goat. This study reveal three colors of rumen fluid such as-greenish, greenish brown, milky grey were found respectively 20%, 40%, 40%, which indicate the normal, alkalosis, acidosis respectively. Odor was found different types, these were –sour (40%), aromatic (20%), pungent (40%) indicating the acid indigestion, normal condition sub acute indigestion respectively. Consistency was found in following order-watery (20%), gruel like (40%), thick watery (40%) respectively. In the same way pH ranged from 5 to 5.9 (40%), 6 to 7 (20%) and remaining above pH 7(40%) that indicate acidosis, normal condition and alkaline indigestion of animal respectively. Study of rumen protozoal motility showed that vigorous (20%), moderate (20%), mild (20%) and absent (40%) were found respectively which indicate that animals in anorexic condition their protozoal motility were mild or absent. Besides the study helps to know about biochemical parameters of different types of minerals and hematological parameters in rumen fluid and blood of digestive disordered goat.2013-06-01T00:00:00Z
