FARMYARD MANURE MANAGEMENT AND ITS EFFECT ON MAIZE FODDER AND SOIL NUTRIENTS
2. MATERIAL AND METHODS
5.3 Improving animal productivity using better selection criteria for offspring from cross- breeding programme
Because dairy bulls are more or less by-products of the dairy industry, the selection of superior bull could only done in medium-size farm where the owner is interested in record keeping and selection. Selection of superior cattle is therefore the responsibility of the breeding station and there must be a permanent set up to keep records and studies. If a calf has a good genetic merit, it should be reared, selected and tested to become a sire if proven good bull.
ACKNOWLEDGEMENTS
Authors express their sincere gratitude to International Atomic Energy Agency (IAEA) for supporting laboratory facilities and technical expertise. Appreciations also go to Dr. Than Daing, former Deputy Director General, LBVD for providing valuable guidance and support to conduct these study. Authors are also very much grateful to Dr.
Khin Htay Myint, Research Officer and Dr. Wint Wint Aung, Assistant Research Officer, Livestock Research and Development Section for their farm management and laboratory work on chemical analysis of research samples. Thanks are also extended to farm workers at the LBVD Research and Development farm and all dairy farmers those who were actively participating in these experiments.
