He attended his elementary, junior high school and senior secondary school in Debre Markos at Abema Elementary School, Tekele Haymanot Junior Secondary School and Debre Markos Comprehensive Senior Secondary School, respectively. After completing his secondary school education he joined the then Alemaya University of Agriculture (AUA) in September 1995 and graduated from the same university in Animal Sciences in BSc degree in July 1999. After graduation the author was employed by Delanta Dawent Woreda Agricultural Office, North Wollo Zone, as an expert and served there for 1 year. He was then employed by EARO (Ethiopian Agricultural Research Organization) in 2001and served at Debre Zeit and Pawe Agricultural Research Centers as a Junior Researcher. The author then transferred to ARARI (Amhara Regional Agricultural Research Institute) in 2003 and joined Andassa Livestock Research Center as a Junior Researcher. The author served at Andassa Livestock Research Center for almost three years and he then joined Haramaya University in September 2006 to resume his MSc degree study in Animal nutrition. viii ACKNOWLEDGEMENTS First, I would like to thank ALRC (Andassa Livestock Research Center), ARARI (Amhara Regional Agricultural Research Institute) and ILRI-IPMS project for financing this study. Secondly, I would like to thank my advisors Dr Solomon Melaku and Dr Azage Tegegne for their contributions in reviewing as well as suggesting valuable comments and advices during the research proposal and the draft thesis writing process. I also thank Dr Eshetie Dejenie for his contribution at the planning stage of this study. I would like to express my gratitude to Ato Tekeba Eshetie (former ALRC Center manager) and Dr Yigzaw Dessalegn (Burie Woreda IPMS Coordinator) for their contribution in providing vehicles and giving valuable advice during the study. I am very grateful to all the staff members of Andassa Livestock Research Center who participated in the survey field work and data collection during the study. My thanks go to Ato Mulugeta Alemayehu, Ato Aseresu Yetayew, Ato Ayana Denberu, Ato Eyaya Molla, Ato Tadelle Habetu and Ato Demelash Dagnaw, Ato Mesfin Eshetu, Ato Zelalem Kefelie, Ato Mesafinet Bezabeh and Ato Ewenetu Bezabeh for their priceless contribution during the field work in Burie Woreda. I greatly appreciate Ato Derejie Fekadu, Holetta Agricultural Research Center researcher, for his straightforward and immediate help in doing the laboratory analysis of the feed samples. Without his help the feed samples chemical analysis would have taken several months to finish. The contributions of Ato Amare Mekonnen and Ato Samson T/ Mariyam in providing the necessary data of Burie Woreda is crucial for the success of this study. I finally thank Burie Woreda Agricultural and rural development office workers who participated in this study. I specially thank Ato Sentayehu, Ato Asemare and Ato Yermedachew Fentie for their help during the study. I would like to express my heartfelt gratitude to the farmers in Woheni Durebetie, Woyenema Ambaye, Denbun and Boko Tabo Kebeles for their time devotion and providing the necessary data for this study. Those farmers in Arebesi, Tiya Tiya and Sertekez Kebeles deserve special thanks as they allowed us to use their animals and resources willingly and devoted their time and energy for the on-farm feeding trials. ix TABLE OF CONTENTS STATEMENT OF THE AUTHOR ..............................................................
