An Information Technology Enabled Poultry Expert System: Perceptions of Veterinarians and Veterinary Students

Article excerpt

ABSTRACT

The Poultry Expert System (PES) was developed using Visual Basic 6.0 and MS Access on selected dimensions of poultry farming. Its efficacy was tested among the Veterinarians and Veterinary students. PES had greater utility, less complexity and moderate compatibility. It possessed good technicality, feasibility, designed in a user friendly and aesthetic manner and brought improvement in the user attributes. Both the groups were significantly differing on few items of applicability. The study concludes that PES is an IT enabled tool for faster dissemination of expert advice in multiple locations at the same time.

INTRODUCTION

Information and Communication Technologies (ICTs) are bringing significant changes to India, as elsewhere. Such ICTs can be exploited to design cost-effective systems to provide expert advice particularly to rural communities, helping increase productivity and livelihoods. (Swaminathan,2003). An Expert System, one such ICT, is an intelligent computer program that uses knowledge and inference procedures to solve problems difficult enough to require significant human expertise to solve (Feigenbaum, 1982). Expert Systems provide a framework for presenting the latest scientific knowledge and decisionmaking tools. Although Expert Systems have been developed in many agricultural science disciplines, such systems do not always adequately address the end user. The issues and challenges in the development of such systems include involving the user in development, building consensus between developer and user on the definition of usefulness, delivering computer based technologies and the challenges of implementing the system rather than its parts (Ostergard et al 1982). Poultry Expert System (PES) attempts to address these issues and was developed using Visual Basic 6.0 and MS Access on four dimensions of poultry farming i. e. diseases, biosecurity, summer management and drugs used. The present study was carried out to test its applicability among end users - veterinarians and veterinary students.

MATERIALS AND METHODS

Veterinarians of Nizamabad district and pre final year students of College of Veterinary Science, Hyderabad, Andhra Pradesh, India were selected randomly @ 30 respondents, representing each group. Poultry Expert System was demonstrated to the respondents by the investigator through a lap top computer. The respondents recorded their response on the interview schedule which had three point continuum i. e. agree, undecided and disagree. The applicability of Poultry Expert System was measured on 29 items, categorized into seven criteria - utility, complexity, compatibility, technicality, feasibility, design and user attributes.

Utility: Ability of PES to be more useful in taking poultry farming decisions, especially when experts are not available; result in saving of time, money and efforts.

Complexity: Denotes easiness in its operation, navigation and understanding of the content through simple language, compared to traditional way of using knowledge system.

Compatibility: The users' rationality in retrieving the knowledge and consequent decision making is indicated by the compatibility of the system, as the traditional system emphasizes more on consultation of the expert.

Technicality: Credibility and accuracy of the content reflects technicality. System with the content derived from experienced expert professional knowledge managers had high reliability and validity.

Feasibility: It is denotes end users adoptability of PES, in lieu of existing mechanism. Adoption Relies on attributes innovation attributes such as relative advantage, trialability, usability, affordability etc.

Design: Holistic presentation of the content; in a more user friendly manner with all the required and satisfy the end user while using. …
