Background: Bioactive compounds in mangosteen peel and turmeric have been shown to possess antioxidant and hypolipidemic properties. Aim: This study aimed to examine the effect of mangosteen peel flour (MF) and turmeric flour (TF) dietary supplementation on the performance, lipid profile, and abdominal fat content of Cihateup ducks. Materials and Methods: The study was conducted for 56 days (8 weeks) using 84-day-old male Cihateup ducks that were allocated into seven treatments with three replications and each containing four ducks as subreplicates. The seven groups were positive control, containing 100% of basal ration/BR + 50 ppm bacitracin (R0), BR + 2% MF (R1), BR + 1.5% MF + 0.5% TF (R2), BR + 1% MF + 1% TF (R3), BR + 0.5% MF + 1.5% TF (R4), BR + 2% TF (R5), and BR only as negative control (R6). The data of each variable were analyzed using a completely randomized design (one way). Significant differences (p<0.05) were determined with Duncan test. Results: The results indicated that the addition of MF and TF significantly affected (p<0.05) body weight, weight gain, mortality rate, low-density lipoprotein, high-density lipoprotein, and abdominal fat levels. At the same time, MF and TF significantly influenced (p<0.01) total cholesterol and triglyceride concentration. Non-significant differences (p>0.05) in feed intake and feed conversion of Cihateup ducks were observed. Conclusion: The combination of MF and TF at a balanced ratio (R3) can be used as an alternative feed additive to improve performance, lipid profile, and abdominal fat of Cihateup ducks.
Abstract. Indonesia is a country that has a lot of limestone mountains, covering 15.4 million hectares. Limestone mountains have strategic functions as limestone is used as building materials and as raw material in cement industry. Therefore, limestone mining quarry in various areas of limestone mountains in Indonesia is increasingly widespread. The biggest negative impact of limestone mining is the formed open land which is abandoned and unutilized. Changes in the ecosystem will lead to the reduced levels of diversity and productivity of indigenous forage which will ultimately reduce the performance and development of ruminants livestock kept by farmers in the mountainous region of limestone. This study aims to determine the diversity and productivity of indigenous forage on former limestone mining quarry in limestone mountains of southern Gombong. The research was conducted through survey by identifying and measuring the forage production of sample plots assigned purposively. Location of the study was divided into three categories, mild, moderate and heavy mining. Results showed that soil fertility levels in open fields of former limestone mining in southern Gombong mountains are low with total N content of 0.049 -0.141%, total P2O5 of 0.067 -0.133% and total K2O of 0.086 -0.100%. The diversity of indigenous forage on mild mining was more diverse than that of moderate and heavy mining, i.e. 13 species comprising 7 grass species, 2 legumes species, and 4 species of shrubs. The most dominant species in all mining categories are Cynodon dactylon, Imperata cylindrica, Ageratum conyzoides and Mikania micrantha. The results also showed that in the open land of mild mining had the highest production of fresh and dry matter compared to that of moderate and severe mining.

Pegunungan kapur memiliki fungsi yang sangat strategis karena batuan kapur banyak dimanfaatkan sebagai bahan bangunan dan bahan pembuatan semen. Oleh karena itu usaha penambangan batu kapur di berbagai wilayah pegunungan kapur di Indonesia semakin berkembang luas. Dampak negatif terbesar dari usaha penambangan batu kapur adalah terbentuknya lahan terbuka yang terlantar dan tidak didayagunakan. Perubahan ekosistem tersebut akan menyebabkan menurunnya tingkat keragaman dan produktivitas hijauan pakan indigenous yang pada akhirnya akan menurunkan tingkat kinerja dan perkembangan ternak ruminansia yang dipelihara oleh peternak di wilayah pegunungan kapur. Penelitian ini bertujuan untuk mengetahui keragaman dan produktivitas hijauan pakan indigenous pada lahan bekas penambangan kapur di pegunungan kapur Gombong selatan. Metode yang digunakan adalah metode survei dengan melakukan inventarisasi dan pengukuran produksi melalui petak contoh secara purposive. Lokasi penelitian terbagi dalam tiga katagori yaitu penambangan ringan, sedang dan berat. Hasil penelitian menunjukkan bahwa ...
Penelitian ini bertujuan untuk mengkaji level yang tepat pemberian kombinasi tepung kulit buah manggis dan tepung kunyit pada ransum terhadap persentase organ dalam itik Cihateup. Penelitian menggunakan 84 ekor DOD itik Cihateup berjenis kelamin jantan yang dikelompokkan secara acak kedalam 7 kelompok perlakuan pakan sebagai berikut: ransum basal saja sebagai kontrol negative (R0); 0,5% TKBM+ 0,5% TK (R1); 1,0% TKBM+ 1,0% TK (R2); 1,5% TKBM+ 1,5% TK (R3); 2,0% TKBM+ 2,0% TK (R4); 2,5% TKBM + 2,5% TK (R5) dan kontrol positif yang mengandung basitrasin 50 ppm (R6). Penelitian dirancang menggunakan rancangan acak lengkap, data dianalisis variansi dan apabila terdapat perbedaan yang nyata akan dilanjutkan menggunakan metode DMRT. Hasil penelitian menunjukkan bahwa level kombinasi tepung kulit buah manggis dan tepung kunyit berpengaruh nyata (P<0.05) terhadap persentase organ dalam (hati, gizzard, limfa dan panjang usus) sementara pada parameter lainnya (proventrikulus, pancreas, bobot usus, ginjal dan jantung) tidak berpengaruh nyata (P>0.05). Penggunaan TKBM dan TK pada ransum itik Cihateup memiliki kecenderungan semakin meningkat seiring bertambahnya dosis. Meskipun demikian, penggunaan pada dosis tinggi perlu dibatasi karena dapat mengakibatkan terjadinya akumulasi toksik pada organ pencernaan sehingga dapat mengurangi karakteristik organ pencernaan. Penggunaan kombinasi tepung kulit buah manggis dan tepung kunyit pada level sedang (1.5%) dapat direkomendasikan sebagai feed additive untuk memperbaiki karakteristik organ dalam itik Cihateup dan ternak unggas lainnya.
The objective of this research was to determine nutrient intake, nutrient digestibility, milk yield, and milk quality of dairy cows that consumed feed supplemented with monensin, garlic peel (Allium sativum), and organic minerals. Twenty-one Friesian Holstein dairy cows with 644±72 kg body weight received dietary treatments consisting of: T0: basal feed + 0.3 g/d monensin;T1: basal feed + 30 ppm garlic-peel powder; and T2: basal feed + 30 ppm garlic peel powder + organic minerals (1.5 ppm Cr, 0.3 ppm Se, and 40 ppm Zn-lysinate). Allocation of dietary treatments followed a completely randomized design with seven replicates per treatment. Results showed that supplementation with monensin, garlic peel, and organic mineral did not significantly affect nutrient intake (DM, OM, CF, CP, NDF, ADF, TDN), nutrient digestibility (DM, OM, CF, NDF, ADF, TDN), milk yield, or milk quality. However, treatment significantly decreased crude protein digestibility (P<0.01). The conclusion was that supplementation with garlic peel can replace monensin in feed for dairy cattle.
