The studies were carried out in Treang district, Takeo province
as a requirement for my Master Degree. These studies have been made
possible with the financial support from Sida-SAREC through the
MEKARN programme. The author would like to appreciate his
appreciation to the Centre for Livestock and Agriculture
Development (CelAgrid) for the support to allow me to implement my
research work successfully in the development area.
I would like to express my deepest thanks to Dr. Preston and Dr.
Khieu Borin for their endless support in correcting, making
constructive comments, inspiring and encouraging me during the
study. They have not only served as my supervisors, but have
provided me so many valuable recommendations beyond teaching. I am
greatly indebted to them.
My gratitude to Prof. Dr. Brain Ogle, MEKARN International
Coordinator, Prof. Dr. Inger Ledin course coordinator, and Dr. Ngo
Van Man Regional Coordinator for their help and support during the
course works. I wish also to thank to organizers in each country
partners with such as UAF, KKU, NAFRI, Cantho University, AnGiang
University, CelAgrid for their efficient assistance during the
course works.
Thanks also for my classmates on the MSc. course from Vietnam,
Thailand, Laos and Cambodia for their friendship and sharing of
knowledge. Many thanks are also extended to the CelAgrid staffs for
their help during my experiments, especially Mr. Pek Samnang and
Chea Chheangly who were my assistants throughout the
experiments.
However, this work would not have been accomplished successfully
without support from my family. Therefore, I would like to express
my sincere gratitude to my parents, my sisters and brothers.
