The studies were carried out during 2006 at the Center for Livestock and Agriculture Development (CelAgrid-UTA Cambodia), Kandal district, and in the districts of Phnom Krovagn and Trang, in Pousat and Takeo provinces, respectively.
The studies are part of the requirement for the Master of Science degree in "Sustainable Livestock Systems", awarded by the Department of Animal Nutrition and Management, Swedish University of Agricultural Sciences, and were made possible through the financial support of the Swedish International Development Agency, Department for Research Cooperation (Sida-SAREC).
I also would like express my deep gratitude to my main supervisors, Professor Brian Ogle and Dr T R Thomas Preston, and my local supervisor, Dr.Khieu Borin, Director of CelAgrid, my local supervisor, for their support, valuable advice and useful guidance during my studies and research project.
I would also like to thank Professor Inger Ledin, for her kind assistance during my course work in Cambodia, Laos, Thailand and Vietnam, and all other professors and lecturers for their great support and scientific guidance during the courses.
Finally I would like to thank the farmers in the six survey villages and the PRA team who participated in the survey, and also the students and staff of CelAgrid who cooperated with and assisted me in carrying out this research.
