FOREWORD
Dr. J. L. Vegad has once againcontributed in a very significant manner to poultry farmers. In practical poultry keeping our belief is that laboratory diagnosis should always be correlated with field conditions and field diagnosis, before embarking on protective and curative measures. Many times we find that laboratory diagnosis indicates a disease which is not the disease of the flock but the disease of an individual bird. Forproper diagnosis and treatment visit to the farm , watching the flock and on-the-spot postmortem is the useful tool. The Colour Atlas will be of tremendous help to the farmers and field diagnosticians. Dr. Vegad has once again shown his insight into practical aspect of poultry keeping and this publication will be of tremendous value. I am sure the industry will receive this with open arms.

This is the first ever such atlas to be produced for Indian farmers and poultry professionals. Its objective is to provide a handy tool to farmers for on-the-spot diagnosis of diseases, under field conditions.

Moreover, by the time birds reach laboratory, they are mostly decomposed and unfit for postmortem examination and disease diagnosis. The delay in diagnosis allows the disease to inflict mortality and ruin farmer's economy. The key to disease control then is on-the-spotdiagnosis. It is with this objective that the colour atlas has been produced - to make readily available to poultry farmers a handy tool for immediate and accurate disease diagnosis under field conditions. A large number of poultry diseases, including the more deadly like Ranikhet and Gumboro, leave their footprints in the dead bird. From these characteristic postmortem findings, it is possible to arriveat a correct diagnosis. The atlas provides 150 coloured photographs and covers a wide spectrum of poultry diseases. For important diseases, several photographs are given so that at no stage their diagnosis is missed. Also, wherever considered appropriate, pictures of live birds showing symptoms of specific diseases are given . In addition, each disease is accompanied by a brief description that...
