Prevalence of Infectious Bursal Disease (IBD) in Selected Commercial Broiler Farms in Hathazari, Chittagong
(A Clinical report presented in partial fulfillment of the requirements for the degree of Doctor of Veterinary Medicine (DVM) under faculty of veterinary medicine. CHITTAGONG VETERINARY AND ANIMAL SCIENCES UNIVERSITY,Khulshi, Chittagong-4225, 2018-09) KADER, MD. ABDUL
Sixty broiler chickens from sixty different small scale farms of Hathazari Upazilla under Chittagong district were studied for two month from 1st February to 29th of March 2018 to determine the prevalence of Infectious Bursal Disease (IBD). On the basis of clinical history and post-mortem lesions, the overall prevalence of IBD in Hathazari Upazilla was 23.33% where highest prevalence was observed in Katirhat area (40%). The major necropsy lesions were observed in the bursa of Fabricious which appeared inflamed, edematous, swollen, hemorrhagic and atrophied. Age related analysis revealed, the 20-35 days aged birds were highly susceptible to IBD (33.33%) followed by 10-19 days aged birds (15.79%) and 1-9 days aged birds (0.00%). Vaccination history medicates the effect of vaccination against IBD was useful as the prevalence of IBD in non-vaccinated and vaccinated birds were 80% and 4.44% respectively. Strong statistical correlation (P=0.018) was observed between insufficient bio-security and IBD infection in broiler farms. This preliminary study medicates the security of IBD in study areas requiring proper control and prevention steps.
PROFITABILITY AND RESOURCE USE EFFICIENCY OF TOMATO PRODUCTION IN SOME SELECTED AREAS OF CUMILLA DISTRICT IN BANGLADESH
(DEPARTMENT OF AGRICULTURAL ECONOMICS, 2018) KADER, MD. ABDUL
The study was conducted to delineate the socio-economic characteristics of tomato producers in the study area; to estimate the costs and returns of tomato production in the study area, to find out the factors that affect profitability of tomato cultivation, and to assess the resource use efficiency of tomato cultivation. Cumilla district was selected purposively for the study on the basis of extensive tomato production. A total of 80 tomato cultivators were randomly selected to conducting farm level survey with pre-tested questionnaire. Data were collected during 1 i st January, 2019 to 31 March, 2019. Per acre cost of tomato production was Tk. 26033 for all farm categories in the study area. Total cost was highest for small farm (Tk. 30903) followed by large farm (Tk. 29602) and medium farm (Tk. 28945). Per acre gross return of tomato cultivation under small, medium and large farms were Tk. 56208, Tk. 54912 and Tk. 52864 respectively which indicates that per acre gross return of small farms were higher than large and medium farms. Per acre gross margin of tomato cultivation under small, medium and large farms were Tk. 38704, Tk. 38551 and Tk. 36126 respectively. Per acre net return of tomato cultivation under small, medium and large farms were Tk. 25305, Tk. 25967 and Tk. 23262 respectively, which indicates that net return was highest in small farms than large and medium farms. Per acre benefit cost ratio (BCR) of tomato cultivation under small, medium and large farm were 1.82, 1.90 and 1.78 respectively. Cobb-Douglas production function model was used to determine the effects of key variable inputs. The most important nine explanatory variables were included in the model to explain the gross income or return of tomato cultivation. Most of the variables in the production function were significant in explaining the gross return except the positive and insignificant effect of human labour cost, urea, MP, irrigation and pesticides. Resource use efficiency indicated that all of the resources were under used for tomato cultivation except overutilization of human labor, TSP and Mop. In the study area, unavailability of good quality seed was the most severe problem among the farmers and lack of irrigation facility was the last problems of the farmers.
