Abstract

ABSTRACTThis research was designed to evaluate nutrient digestibility, mentioned as Total Digestible Nutrient of diet containing PUFA (polyunsaturated fatty acid) - concentrate supplemented with yeast and Curcuma xanthorrhiza Roxb for dairy goat. Twenty Ettawah crossbred goat in late lactation were allocated into 6 treatments in randomized block design. The treatments were PD0: PUFA-diet with no supplement, PDA: with Asifit, PDY: with 0.5% yeast, PDC: with 1.5% curcuma, and PDM: with 0.5% yeast + 1.5% curcuma. The PUFA-diet contained of 80% PUFA- concentrate as basic diet and 20% Pennisetum purpureum. While the PUFA sources were roasted ground corn and roasted soybean meal, and corn oil. Results showed that intakes of DM, OM, CP, CF, NFE, ADF, and GE were not affected significantly by dietary treatments. However, EE and NDF among treatments were different significantly (P<0.05), whereas Ca and P were different very significantly (P<0.01). High nutrient contents (DM, OM, CP, EE, CF, NDF, and GE) were found in feces of the goat with curcuma diet (PDC), consequently showed the opposite effects by giving the lowest digestibility (P<0.05 or P<0.01) of these nutrients. Total digestible nutrient (TDN) of PDY and PDM were markedly higher (79.89% and 79.37%, respectively) than that in other diets, such as being the lowest was in PDC (69.94%). This suggested that the yeast concentration of 1.8 108cfu/d, given singly or in combination with 1.5% Curcuma could be considered as the right level for improving nutrient digestibility in the late lactation goat in our study.Keywords: curcuma, dairy goat, PUFA-diet, TDN, yeast

Abstract

Bark, especially from Acacia mangium is a by-product from wood processing industries that commonly found in Indonesiaand in big amount will cause environmental problems. One of the alternatives to utilize bark is for animal feed. The aims of this experiment are to improve the nutritive value of bark by alkali treatments (urea and sodium hydroxide) and to determine the level of substitution of elephant grass by bark. The experiment consisted of 3 in vitro studies and 1 in sacco study. In vitro studies consisted of 1) the use of urea or NaOH by wetting and incubation-method, 2) the use of different concentration of Na OH (0-4%) by soaking method, 3) determination of substitution level of elephant grass by treated bark. In sacco study was conducted at 0, 6, 12, 24, 48 and 72 hours of incubation to compare the degradation of treated bark to elephant grass. The results show that urea treatment did not improve DM or OM digestibilities of bark. Soaking bark in 4% NaOH solution was more effective than wetting and incubation-method in improving in vitro digestibility. (49.26% vs19.56% for soaking and dry-method, respectively). In sacco studyl shows that treated bark had a very high solubility at 0 hour incubation but the degradation at 72 hours incubation was not significantly different from that of 0 hour incubation. The gas produced at in vitro study of treated bark was very low indicated that there was no degradation of bark at all. The level of substitution of elephant grass by treated bark up to 30% gave a non-significant digestibility value to that of 100% elephant grass. In conclusion, bark after tannin-extraction was a better feedstuff for animal feed. The soaking method in 4% NaOH solution improved the digestibility of bark significantly and the level of substitution of elephant grass by treated bark was 30%.   Key words: Bark, acacia mangium, urea, sodium hydroxide, digestibility

Abstract

Milk quality is affected by feed nutrient either macronutrient or micronutrient.  Roasted soayabeans and calcium soap were to increase supply by pas protein and fat to dairy cattle. Thus, organic mineral was to increase bioavailability of feed mineral to animal.  The objective of this study was to evaluate roasted soybean, mineral soap and organic mineral supplementation on milk quality of dairy cattle.  Twenty lactating Frisian Holstein cows (initial weight 361.4 ± 40.39 kg) were assigned into a randomized complete block design with 5 treatments and 4 blocks. The treatments were A: basal diet, B: A + roasted soybean, C: B + calcium soap of corn oil, D: C + calcium soap of corn oil, E: C + calcium soap of fish oil. The experimental diets were offered for 9 and 2 weeks preliminary. The results of the experiment showed that milk protein and lactose were not affected by diets.  Milk dry matter  of cows fed A, B, and D diets were higher (P<0.05) than those of fed C and E diets.  Milk fat of cows fed A,  B and D diets were higher (P<0.05) than those of  fed C and E diets. Milk density of cows fed B and E diets were higher (p<0.05) than those of fed A, C and D diets. Milk TPC of cows fed B diet were higher (0.05) than those of fed A, C, D, and E diets. It is concluded that milk quality especially milk protein and lactose concentration are not affected by roasted soyabeans, Ca-soap, and organic mineral. Calcium soap of fish oil and organic mineral decrease population of milk bacteria. Key Words: Calcium Soap, Organic Mineral, Roasted Soyabeans, Dairy Cattle, Quality Milk

Abstract

Seng sangat penting di dalam sistem kekebalan tubuh. Akan tetapi,kandungannya di dalam bahan pakan di Indonesia secara umum rendah. Ternakbanyak mengeluarkan seng melalui urine bila mengalami cekaman transportasi,oleh karena itu kebutuhan seng mungkin meningkat. Penelitian ini bertujuanuntuk melihat mineral plasma dan respons antibodi setelah mengalami cekamantransportasi. Enam belas domba ekor tipis jantan dialokasikan ke dalamRancangan Acak Lengkap dengan menggunakan ransum basal yang memilikikandungan Zn sebesar 22.8 ppm. Perlakuan terdiri atas; ransum basal (R1), R1 +36 ppm Zn (R2), R1 + minyak ikan 1.5% (R3) dan R1 + 36 ppm Zn + minyak ikan1.5% 1.5% (R4). Ternak domba diberi makan dua kali pada jam 08.00 dan 16.00.Masing masing domba divaksinasi dengan Clostridium perfringens pada 41 dan 3hari sebelum transportasi. Ketika ternak mengalami cekaman transportasidiperoleh kondisi fisiologis sebagai berikut : (1) Seng plasma menurun untuksemua perlakuan (2) Kalium dan Mg plasma menurun dan kembali normal padajam ke-88 setelah transportasi (3) Natrium plasma meningkat pada perlakuan Zn+ minyak ikan pada jam ke-40 (4) Suplementasi Zn meningkatkan responsantibodi. Hasil penelitian ini dapat disimpulkan bahwa suplementasi Znmeningkatkan kekebalan tubuh dan kadar seng mungkin perlu ditingkatkan lagidalam ransum setelah ternak mengalami cekaman transportasi.

Abstract

Penelitian ini bertujuan untuk mengkaji pengaruh suplementasi tepung kulit manggis (TKM) dan Vitamin E (VE) di dalam ransum ayam ras petelur terhadap kualitas fisik telur selama penyimpanan pada waktu dan suhu yang berbeda. Ayam petelur diberi perlakuan pakan yaitu : R0 (ransum kontrol), R1 (R0 +1 g TKM/Kg ransum), R2 (R0 + 2 g TKM/Kg ransum) dan R3 (R0 + 200 mg VE/Kg ransum). Rancangan yang digunakan adalah rancangan acak lengkap pola faktorial 4 x 3 x 2 dengan 4 ulangan. Faktor pertama yaitu ransum, faktor kedua yaitu: waktu penyimpanan (1, 2 dan 3 minggu) dan faktor ketiga yaitu suhu penyimpanan pada refrigerator (4,13oC dan 22,50%) dan suhu ruang (27, 47oC dan 76,17%). Variabel yang diamati adalah: berat telur, persentase kerabang telur, persentase kuning telur, persentase putih telur, tebal kerabang, warna kuning telur dan Haught unit (HU). Hasil penelitian menunjukkan bahwa interaksi antara ransum, waktu dan suhu selama penyimpanan sangat nyata (P<0,01) menurunkan warna kuning telur. Waktu dan suhu penyimpanan sangat nyata (P<0,01) menurunkan HU dan meningkatkan persentase kuning telur. Interaksi waktu dan suhu penyimpanan nyata (P<0,05) menurunkan persentase putih telur. Tebal kerabang nyata (P<0,05) meningkat dipengaruhi oleh ransum dan sangat nyata (P<0,01) meningkat dipengaruhi oleh waktu penyimpanan. Berat telur dan persentase kerabang telur tidak dipengaruhi oleh ransum, waktu dan suhu penyimpanan. Kesimpulan penelitian adalah suplementasi tepung kulit manggis dan Vitamin E di dalam ransum ayam ras petelur strain Lohmann secara umum tidak mempengaruhi kualitas fisik telur (kecuali warna kuning telur dan tebal kerabang) yang disimpan pada waktu dan suhu yang berbeda. Kualitas fisik telur lebih utama dipengaruhi oleh waktu dan suhu penyimpanan yang berbeda. Suhu dan kelembaban terbaik untuk penyimpanan telur adalah 4,13oC dan 22,50% pada refrigerator, pada kondisi ini telur dapat disimpan selama 21 hari.
