Sundarbans estuary of India is rich in biodiversity and under the threat of contamination by various xenobiotics including diesel. Motorised boats run by diesel are the chief mode of transport across the river and creeks of Sundarbans mangrove. Occasional spillage of diesel from these vessels often contaminates the water and littoral habitat of mud whelk, an important molluscan resident of this estuary. Hemocytes, the chief immunoeffector cells of mollusc perform diverse physiological functions like nonself recognition, biological plug formation by aggregation, elicitation of cytotoxicity and phagocytosis. Undesirable shift in hemocyte density, nonself recognition ability and cytotoxicity in mud whelk exposed to diesel are indicative to impairment of immune status and reduction of survival fitness of this species in its natural habitat. Prolonged exposure and toxicity of diesel in benthic community may lead to a gradual loss of littoral biodiversity of Sundarbans estuary.

This book deals specifically with basic managemental aspects of dairy animal in the context of Indian subcontinent. The informations are carefully presented in concise manner and to the point. The entire book has been prepared in most simple, clear and talking language for easy understanding. In this book, an attempt has been made to introduce both the science and practice of dairy animal production for the students, teachers, progressive farmers and extension workers. Any book which attempt to cover the needs of much a wide range of people must have their limitations as far as any one group of persons is concerned. It is hoped however that all those who read these books will find some guidance and instruction which will enable them to improve their knowledge and understanding of the management and production of dairy animals.
