ABSTRACT The purpose of this experiment was to know the body dimensions of Kampong chickens at the pullet phase after l-threonine and l-tryptophan supplement in the feed. This experiment was conducted in Kelurahan Sasi and the Laboratory of Agricultural Faculty, University of Timor, Kefamenanu from July 2019 to September 2019. The experiment used 96 fourteen-week kampong chickens, was designed with a Completely Randomized Design, consisting of 4 treatments and 4 replications. The dietary treatments were T0 (control feed), T1 (supplementation of 0.15% l-threonine and 0.06% l-tryptophan), T2 (supplementation of 0.37% l-threonine and 0.11% l-tryptophan), and T3 (supplementation of 0.50% l-threonine and 0.15% l-tryptophan). The variables measured were body weight, chest circle, sternum length, wing length, back length, femur, tibia, and shank circle. Data obtained was analyzed by analysis of variance and Duncan’s test. The result showed that the bodyweight of T0, T1, T2, and T3 were 1542.83±10.54, 1600.03±1.82, 1638.49±14.97, and 1716.85±23.84 g/bird, respectively. The chest circle, wing length, back length, sternum length, femur, tibia, circle and length of shank were 26.20±1.87, 26.38±0.47, 28.63±2.21, and 29.83±1.83 cm/bird; 17.78±1.00, 17.98±0.36, 18.75±0.95, and 19.85±1.63 cm/bird; 15.75±0.64, 16.50±1.08, 18.50±0.57, and 18.38±0.85 cm/bird; 12.93±1.77, 13.75±1.19, 13.88±0.85, and 14.73±0.48 cm/bird; 10.50±0.70, 10.93±1.20, 10.95±0.10, and 11.73±0.73 g/bird; 10.70±0.50, 11.10±0.89, 12.23±0.58, and 12.15±0.57 cm/bird; 4.23±0.05, 4.20±0.21, 4.23±0.22, and 4.40±0.20 cm/bird; and 8.90±0.11; 8.88±0.47; 9.13±0.62, and 10.38±0.62 cm/bird, respectively. Statistical analysis showed that levels of l-threonine and l-tryptophan significantly affected body weight, chest circle, sternum length, wing length, and back length (P<0,05). It was concluded that supplementation with 0.50% l-threonine and 0.15% l-tryptophan to the diet increases the body dimensions kampong chickens at the pullet phase.

This research was conducted in 2021 for 3 months at the Faculty of Agriculture, University of Timor. The purpose of this study was to determine the blood glucose and urea levels of male Bali cattle fattened with complete feed containing fish meal as a protein source. This research method uses a completely randomized design (CRD) with 3 treatments and 5 replications so that there are 15 experimental units with treatment given T1; natural grass 30% + milled corn 42% + rice bran 13% + pollard bran 11% + fish meal 4%, T2: natural grass 42% + milled corn 42% + rice bran 9% + pollard bran 11% + fish meal 8 %, T3: natural grass 30% + milled corn 42% + rice bran 5% + pollard bran 11% + fish meal 12%. The variables observed in this study were blood glucose and blood urea levels of male Bali cattle with a time of 0 hours before feeding, 2 hours, 4 hours, and 6 hours after feeding. The data obtained were tabulated and then analyzed by Analysis of Variance (ANOVA) according to a completely randomized design procedure (CRD) using SPSS version 19.0. The results of this study showed that the use of complete feed containing fish meal as a protein source was not significantly different. Blood glucose levels (mg/dL) for each treatment were T1: 73.23±3.50, T2: 76.24±6.21, T3: 71.94±2.54; Blood urea levels (mg/dL) of male Bali cattle for each treatment were T1: 40.23±3.51, T2: 40.95±2.04, T3: 39.67±1.83. It was concluded that giving a complete feed containing fish meal as a protein source gave the same effect for all treatments and resulted in blood glucose and urea levels of fattened male Bali cattle in the normal range.

This research investigated the impact of different additives on the physical quality of king grass-based complete silage (Pennisetum purpureoides). This study was carried out at the Laboratory of the Faculty of Agriculture, Science, and Health, University of Timor, during the period of July–August 2023. A Completely Randomized Design (CRD) was employed, consisting of treatments with replications each. The treatments included: P0 as the control (100 % king grass without additives), P1 (70% king grass + 20% rice bran + 5% Gliricidia sepium leaves + 5% sugar), P2 (70% king grass + 20% corn flour + 5% Gliricidia sepium leaves + 5% sugar), and P3 (70% king grass + 20% soybean meal + 5% Gliricidia sepium leaves + 5% sugar). The percentages of additional ingredients were calculated based on the weight of the main materials, consisting of chopped king grass and Gliricidia leaves. The parameters analyzed included color, aroma, texture, and mold presence assessed through sensory evaluation, while pH measurements were conducted using a pH meter. The percentage of mold contamination was determined by comparing the weight of the moldy portion of the silage to the total silage weight. The results indicated that the addition of additives had a significant effect (p<0.05) on the color, aroma, pH, texture, and mold development of the silage. Overall, the soybean meal treatment produced the best performance, as it effectively inhibited mold growth and generated a more desirable silage aroma compared to the control, rice bran, and corn flour treatments.

Balinese cattle are one of the local cattle breeds that have great potential in supporting domestic meat needs. As beef cattle, Balinese cattle are known to have high adaptability to Indonesia's tropical environment and good fertility rates, making them the right choice to be developed in order to increase the availability of animal food. This study aims to determine the correlation value of chest circumference and body length to body weight, carcass and non-carcass weight of 56 Balinese cattle slaughtered at the Slaughterhouse in Kefamenanu City. Data analysis uses descriptive analysis to determine body weight, chest circumference, carcass weight, and non-carcass weight. The results of the study showed that in the Kefamenanu RPH, the average body length was 122.71 cm, producing a body weight of 212.02 kg, a carcass weight of 67.34 kg and a carcass weight of 145.54. While the average chest circumference of Balinese cattle that were slaughtered with non-weight was 167.59 cm, producing a body weight of 212.02 kg, a carcass weight of 67.34 kg and a non-carcass weight of 145.54 kg, the correlation value between body length and body weight, carcass weight and non-carcass weight of Balinese cattle ranged from 0.071-0.46, and the correlation value between chest circumference and body weight, carcass weight and non-carcass weight of Balinese cattle ranged from 0.223-0.444. Based on this study, the carcass and non-carcass weight produced, the Kefamenanu RPH needs to set a standard for the body weight of Balinese cattle that are slaughtered
