520	3		_aELIZABETH. MAGAY, University of the Philippines at Los Banos, April, 1982. Protein and Energy Requirements of Growing Philippine Native Goats. Major Professor: Dr. Cledualdo B. Perez, Jr. A feeding and slaughter experiment was conducted at the University of the Philippines at Los Banos to determine the protein and energy requirements of native goats at 5 — 14 kg live weight. Nine rations, consisting of various combinations of 3 levels of protein (12, 16, 20% CP) and 3 levels of energy (53, 60, 68% TDN) were used. Dry matter digestibility increased with increasing energy level. Crude 'protein digestibility was not affected by either protein or energy level while that of ether extract was depressed by higher protein. The digestibility of crude fiber was decreased by increasing energy and also by increasing protein level. Weanling goats at 5 kg live weight did not survive on a ration containing 12% CP and 49;6 TDN. They required 16% CP and 59% TDN to produce daily gain of at least 25 g. It higher live weight higher protein and energy levels effected the best gain, but the time lag for the low energy rations to produce similar gain was not as wide as that observed at lower live Rumen pH decreased and total volatile fatty acid increased with increasing energy while ammonia nitrogen increased with increasing protein level. Blood urea nitrogen was increased by increasing protein and decreased by increasing energy level. Carcass composition (% protein, fat) was constant at all levels of protein and energy. The proportion of fat in the non-carcass components, specifically in the viscera, increased with increasing energy level. Increasing energy level promoted higher and more efficient protein deposition and energy accumulation. It also resulted in higher dressing percentage and heavier weight of lean.
