forage yield and animal intake. An average weight gain of 0.28 kg per day was obtained with Holstein and carabao bulls, the carabaos gaining faster in the dry season than cattle consuming the same forage. The data on intake and nutritive value led to an estimate of 4.0 kg of milk per cow per day as the maximum production which could be supported by a ration of guinea grass soilage (prebloom stage, 28-42 days old) without supplementation.

F-32 EVALUATION OF GROWTH PERFORMANCE OF <strong>PHILIPPINE</strong> CARABAO AND PHIL-MURRAH CROSSES UNDER DIFFERENT FEEDING REGIMES: UREA-TREATED STRAW AND ENERGY SUPPLEMENTATION* R. M. Lapitan, Supervising Science Research Specialist, Philippine Carabao Center, Department of Agriculture, University of the Philippines Los Baños B. A. Oliveros, Assistant Professor, Institute of Animal Science, College of Agriculture, University of the Philippines Los Baños A. N. del Barrio, Supervising Science Research Specialist, Philippine Carabao Center, Department of Agriculture, University of the Philippines Los Baños V. G. Momongan, Professor, Institute of Animal Science, College of Agriculture, University of the Philippines Los Baños The comparative growth performance of 6 Philippine carabao (PC) and 6 Phil-Murrah (PM) crossbred carabaos fed urea treated straw supplemented with concentrate was investigated following a 2 x 2 factorial in a randomized completed block design (RCBD). The two factors were breed and levels of energy intake. Low energy intake was set to provide maintenance requirement while high energy intake allowed the animals to gain 0.5 kg/day. Daily rice straw dry matter intake of both the PC (6.44 kg) and the PM (5.97 kg) at low energy intake were significantly (P

Orden, Instructor, Department of Animal Science, College of Agriculture, Central Luzon State University D. D. Lorenzo, Instructor, Department of Animal Science, College of Agriculture, Central Luzon State University A total of six (6) caraheifers aged 2 to 3 years old with body weight ranging from 280 to 287 kg were used as experimental animals to determine their voluntary intake and the digestibility of Themeda range pasture during summer. The calculated mean voluntary dry matter intake was 3.78 ± 0.18 kg which is equivalent to 1.31 ± 0.06 percent of the body weight. This intake is on the average 53.98 ± 2.41 dry matter of Themeda per kg metabolic body size. The unimproved themeda range pasture at summer time gave a mean value for dry matter digestibility and digestion coefficients for crude fiber (CF), crude protein (CP), nitrogen free extract (NFE) and ether extract (EE) of 40.61 ± 1.32, 56.58 ± 2.21, 17.00 ± 3.63, 52.41 ± 1.77 and 59.61 ± 5.10 percent, respectively. The total digestible nutrient was found to be 45.20 ± 1.56 percent. Digestible energy was 356.08 ± 74.84 cal/g.

F-35 VARIATIONS IN <strong>THE</strong> NITROGEN FRACTIONS OF RUMEN LIQUORS OF SLAUGHTERED CARABAOS* P. L. Lopez, Associate Professor, Department of Animal Science, College of Agriculture, University of the Philippines Los Baños M. S. Banes, Research Assistant, Department of Animal Science, College of Agriculture, University of the Philippines Los Baños E. C. Ricohermoso, Research Assistant, Department of Animal Science, College of Agriculture, University of the Philippines Los Baños The total N values for fasted female carabaos ranged from 30.84 to 226.29 mg % with a mean value of 77.40 mg % while that of the non-fasted ranged from 64.76 to 218.20 mg % with a mean value of 106.82 mg %. The fasted and non-fasted steers, however, have very close mean for total N (106.90 to 106.57 mg %) although, the range was just as wide from 39.32 to 179.84 mg % with fasted steers and from 60.76 to 160.84 mg % with non-fasted steers. The fasted bulls have values ranging from 31.02 to 150.94 mg % with a mean value of 70.67 mg % while the nonfasted bulls have values ranging from 83.10 to 132.85 mg FEEDING AND NUTRITION % with a mean value of 108.31 mg %. The male carabaos showed slightly higher mean (101.67 mg %) for total N than the female (91.47 mg %). Similarly, the non-fasted carabaos showed higher mean (106.78 mg %) than the fasted (88.13 mg %) animals. The range in protein N was just as wide as the total N. The mean values for female and male carabaos were 64.88 and 75.67 mg %, respectively. However, the female and bulls were comparable in the mean protein N, 64.88 and 64.44%, respectively, which were lower than that of the steers (82.02%). There was only a slight difference in the mean protein N for the fasted (70.26%) and non-fasted (71.52%) carabaos. Non-protein N for fasted female carabaos ranged from 6.80 to 34.95 mg % with a mean value of 17.29 mg % while that of the non-fasted ranged from 11.73 to 54.88 mg % with a mean value of 36.73 mg %. The fasted steers had NPN values from 8.37 to 54.66 mg % with a mean of 20.09 to 53.29 mg % with a mean value of 32.83 mg %. The fasted bulls ranged from 15.16 to 33.03 mg % and non-fasted of 23.77 mg % and from 20.30 to 67.52 mg % with a mean value of 33.77 mg %. The mean NPN values for steers and bulls were about equal (24.55 and 24.46 mg %) but these values were slightly lower than that of the female (26.61 mg %). There was a marked decrease in NPN from non-fasted (35.37 mg %) to fasted (19.46 mg %) carabaos. Ammonia N values fell within the same range as the NPN, although the mean values were generally lower. Similar to protein N, the mean NH 3 - N of females and bulls were about equal (17.48 and 17.30 mg %), respectively, a one and half percentage unit higher than the mean value for steers (15.94%). The mean value for non-fasted carabaos was much higher (22.48 mg %). The difference was just as marked as the difference in the NPN. The total N and all nitrogen fraction (PN
