The present study was conducted to investigate the status of  current antibiotics use and vaccine application program in commercial broiler farming, to understand about the current market scenario of antibiotics and vaccine related products and to identify the major problems of broiler farming and suggestions for its improvements. For achieving these objectives, 50 broiler farms and 20 antibiotics-vaccine products sellers were selected purposively from 5 selected unions of Sakhipur upazila in Tangail district. In the study area, 42% respondent had a slim idea about residual effect of antibiotics. Most of the farmers in the visited area used almost same types of antibiotics. Among the farms surveyed, 98% farms practiced proper vaccination. Among the 50 farmers, 66% farmers had idea about sound vaccination program and 98% farmer thought that vaccination is essential for their farming. In the study area, 70% farmers got their antibiotics and vaccine from dealer. The study showed that antibiotic cost is only 3.53% and vaccination cost is 1.06% of the total cost. Regarding the antibiotics use, results were alarming and found that 100% respondents used antibiotics in broiler production. Both positive and negative significant correlations were observed for different parameters. The problems related to present antibiotics and vaccination program and their probable solutions suggested by broiler farmers were also focused in this study.Progressive Agriculture 27 (4): 490-501, 2016

Historically, the minimality of surfaces is extremely important in mathematics and the study of minimal surfaces is a central problem, which has been widely concerned by mathematicians. Meanwhile, the study of the shape and the properties of the production models is a great interest subject in economic analysis. The aim of this paper is to study the minimality of quasi-sum production functions as graphs in a Euclidean space. We obtain minimal characterizations of quasi-sum production functions with two or three factors as hypersurfaces in Euclidean spaces. As a result, our results also give a classification of minimal quasi-sum hypersurfaces in dimensions two and three.

It is well known that the study of the shape and the properties of the production possibility frontier is a subject of great interest in economic analysis. Vîlcu (Vîlcu, 2011) proved that the generalized Cobb-Douglas production function has constant return to scale if and only if the corresponding hypersurface is developable. Later on, the authors A. D. Vîlcu and G. E. Vîlcu, 2011 extended this result to the case of CES production function. Both results establish an interesting link between some fundamental notions in the theory of production functions and the differential geometry of hypersurfaces in Euclidean spaces. In this paper, we give some characterizations of minimal generalized Cobb-Douglas and CES production hypersurfaces in Euclidean spaces.
