This study aims to determine the effect of using young coconut water as a diluent on viability, spermatozoa abnormalities and pH of ram semen. This research has been carried out for 2 months, from June to August 2021, and has been carried out in a sheep semen shelter in Naiola Village, South Bikomi District, North Central Timor Regency and evaluated at the Laboratory of the Faculty of Agriculture, Timor University. This study used a completely randomized design (CRD) with four treatments and five replications. The R1 treatment without young coconut water, R2 treatment 10% young coconut water, R3 treatment 15% young coconut water, R4 treatment 20% young coconut water. The results showed that the effect of treatment was significantly different (P<0.05) on the viability of spermatozoa. The average spermatozoa viability of each treatment was P1 of 78,0±8,15, P2 of 75,2±7,79, P3 of 71,8±9,44 and P4 of 66,8±4,54. Spermatozoa abnormalities were not significantly different (P>0.05). Spermatozoa abnormalities of treatment P1 were 8,4±1,14, P2 was 9,2±0,83, P3 was 9,4±1,34 and P4 was 9,6±3,84. The degree of acidity (pH) of semen was significantly different (P<0.05) between treatments. The pH values of each treatment were P1 of 6,79±0,16, P2 of 6,53±0,34, P3 of 6,47±0,33, and P4 of 6,35±0,20. So this study concluded that the addition of young coconut water level of (20%) can still maintain the viability, normality of spermatozoa and pH of ram semen.

The objective of this research was to analyze the composition of saturated fatty acid, unsaturated fatty acids, and cholesterol in meat of Bali bull fattened using forage crops in small holder farming. The experiment was conducted for 3 months using nine Bali bull aged 2.5-3.5 years old with the initial body weight of 227-290 kg in the feedlots of Bero Sembada Farmers Group, Laen Manen Sub District, Malaka Regency, East Nusa Tenggara. The experiment was conducted based on the fattening system of local farmers in terms of feeding, housing, and health management. Feed given during the experiment was Centrosema pubences, Clitoria ternatea, fresh corn straw, king grass, Leucaena leucocepala, natural grass, Pennisteum purpureum, and Sesbania grandiflora. At the end of this study, cattle were slaughtered and the composition of saturated fatty acid, unsaturated fatty acids and cholesterol were measured. Data were analyzed using a descriptive statistic. Results revealed that the total of saturated fatty acid and unsaturated fatty acids in meat were 36.628% and 26.739%, respectively, while the cholesterol reached 79.18 mg/100 g of meat. In conclusion, meat of Bali bull fattened using forage crops in small holder farming has higher saturated fatty acid than unsaturated fatty acids.

Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian suplemen organik cair GDM terhadap pertumbuhan, pertambahan bobot badan, konsumsi pakan, dan konversi pakan pada Ayam Kampung (Gallus domesticus) yang dipelihara. Penelitian ini telah dilaksanakan di kandang Program Studi Peternakan, Fakultas Pertanian, Universitas Timor selama 12 minggu; sejak bulan Januari sampai Maret 2022. Penelitian ini menggunakan 20 ekor Ayam Kampung berumur 8 minggu. Metode yang digunakan adalah Rancangan Acak Lengkap yang terdiri dari 4 perlakuan dan 5 ulangan dengan masing-masing ulangan menggunakan 1 ekor ayam. Perlakuan yang diberikan adalah R0 (tanpa suplemen organik cair GDM), R1 (suplemen organik cair GDM 0,3 ml), R2 (suplemen organik cair GDM 0,5 ml), dan R3 (suplemen organik cair GDM 0,7 ml). Variabel dalam penelitian ini meliputi pertambahan bobot badan, konsumsi pakan, dan konversi pakan. Data yang diperoleh dianalisis dengan sidik ragam (ANOVA) dan dilanjutkan dengan Uji Jarak Berganda Duncan. Hasil penelitian perlakuan R0, R1, R2, dan R3 berturut-turut menunjukkan bahwa pertambahan berat sebesar 127,00±2,54, 137,40±3,91, 138,60±2,88, dan 128,00±5,38 g/ekor/minggu; konsumsi pakan sebesar 758,308±38,45, 724,286±13,91, 710,056±18,69, dan 741,424±73,15 g/ekor/minggu; serta konversi pakan sebesar 5,972±0,33, 5,274±0,14, 5,122±0,07, dan 5,788±0,42. Analisis sidik ragam menunjukkan bahwa perlakuan suplemen organik cair GDM berbeda nyata terhadap pertambahan bobot badan dan konversi pakan (P<0,05) sedangkan konsumsi pakan tidak signifikan. Disimpulkan bahwa suplemen organik cair GDM 0,3 dan 0,5 yang dicampurkan kedalam air minum memberikan hasil terbaik pada pertambahan bobot badan dan konversi pakan Ayam Kampung.

This study aimed to evaluate the performance of Balinese bulls fattened by various forages on traditional farms. The study was experimental research using Clitoria ternatea, Zea mays fresh straw, Pennisetum purpuphoides, Pennisetum purpureum, Sesbania grandiflora, Centrosema pubescens, Leucaena leucocephala, and natural grass to fatten the livestock which were arranged for the farmers' habits in fattening. Variables measured included feed consumption and digestibility and livestock growth performance, including daily body weight gain (PBBH), feed conversion and efficiency, and feed cost per gain. The collected data were then analysed using descriptive analysis procedures. The results showed that fattening Balinese bulls with forage resulted in dry matter (DM) (kg/head/day) reaching 7.079, while crude protein (CP) and organic matter (OM) intake were respectively 1.053 and 6.440 (kg/head/day). The digestibility coefficient of dry matter was 56.68%, crude protein was 69.86%, and organic matter was 68.83%. The ADG obtained by livestock was 0.321 kg/head/day; meanwhile, the feed conversion and efficiency were respectively 23.664 kg.DM/kg.ADG and 4.619%; the feed cost per gain (IDR/kg.ADG) reached 10,813.85. To sum up, the use of various types of forage in fattening Balinese bulls on traditional farms indicates that DM, OM, and CP intake are relatively high, but it provides relatively low feed digestibility by mean of ADG, conversion, and feed efficiency are not optimal.
