Abstract

The potential availability of forage feed is high, but in reality this potential has not been able to meet the requirement of feed both in sustainable quantity and quality. Silage made with the use of liquid fermentation additive (FA) can be a solution for those problems. The use of  different levels of FA and addition of Lactobacillus plantarum bacteria as well as formic acid were expected to improve the nutritive quality of napier grass silage. The first experiment was designed to measure the fermentative quality of napier grass silage. The treatments used were the levels of FA, L. plantarum, and formic acid supplementations. The experiment used a completely randomized design with a 3x2x2 factorial arrangement with 3 replications. The first factor was the level of liquid FA (5%, 7.5%, and 10%), and the second factor was the inoculation of L. plantarum (without and with inoculation of the L. plantarum), and the third factor was the addition of formic acid (without and with the addition of 0.15% formic acid). The second experiment was aimed to evaluate chemical and microbiological characteristics, and in vitro digestibility of selected napier grass silage. The results showed that napier grass silage from all treatments showed good qualities. There were interactions between FA, L. plantarum, and formic acid on DM content (P<0.05) and ammonia production (P<0.01). The use of FA showed an interaction (P<0.01) with the addition of L. plantarum and formic acid in Fleigh point. Ammonia production in rumen (P<0.01), total VFA (P<0.05), and in vitro digestibility (P<0.01) were significantly affected by the treatments. The optimal level of liquid FA was 7.5%. Based on the nutritive quality of silage, L. plantarum addition was as effective as control treatment to improve nutritive quality of napier grass silage through the increased  of fermentation characteristics i.e., low pH, high DM product, high fermentation product (VFA), and digestible on rumen. Formic acid reduced ammonia production during ensiling and fermentation in rumen, but it was less effective in inhibiting the fermentation process when it was combined with L. plantarum.

Abstract

Canola oil and flaxseed oil are vegetable oils as potential sources of unsaturated fatty acid that could improve the production and quality of beef meat.  However, the use of vegetable oils need to be protected to avoid biohydrogenation by rumen bacteria.  The research was aimed to analyse effect of flaxseed/canola oils calcium soap in the different buffer media on in vitro fermentation characteristic.  The experiment was conducted in a factorial randomized block design with 2 factors and 3 blocks based on rumen sampling time.  The first factor was sources of vegetable oils (canola and falxseed) and the second factor was type of buffer (Kajikawa and Mc.Dougall).  Variables observed were pH value, N-NH3 concentration, total volatile fatty acid (VFA), dry matter and organic matter digestibility.  Data obtained was analysed using Analysis of Variance and any significant different further tested using Duncan Multiple Range Test.  The results showed that there was no interaction between sources of diet and buffer.  Supplementation of canola and flaxseed oils protected by calcium soap at level 6% did not affect pH value, dry matter digestibility, rumen protozoa and total bacteria.  The use of different buffers affected pH value, dry matter digestibility, rumen protozoa and total bacteria.  It’s concluded that the used of flaxseed oil or canola oil calcium soap did not alter rumen fermentation and McDougall buffer could improve in vitro fermentation activity compare to Kajikawa buffer.

Abstract

ABSTRAK Tujuan penelitian ini adalahmembuat kartu skor (score card) untuk penilaian sistem grading dan kontes kambing kaligesing. Hasil penelitian  menunjukkan bahwa terdapat tiga faktor determinan dalam sistem grading kambing kaligesing yang telah lama berlaku di tingkat peternak, yaitu faktor ukuran tubuh, profil muka dan leher, serta ukuran telinga. Penilaian eksterior pada kambing perah biasanya menggunakan kartu skor yang seragam dan telah dibakukan. Kartu skor dibuat berdasarkan ketiga faktor determinan sistem grading menurut peternak. Kartu skor terdiri atas komponen-komponen penilaian kuantitatif dan kualitatif. Komponen kuantitatif meliputi ukuran badan dan ukuran telinga dengan bobot total 70%, komponen kualitatif meliputi profil kepala dan leher dengan bobot total 30%. Komponen ukuran badan memiliki bobot terbesar (55%) dibandingkan dengan komponen yang lainnya. Hal tersebut dimungkinkan karena ukuran badan banyak digunakan dalam proses jual beli Kambing PE, misalnya tinggi pundak dan bobot badan (Kambingetawa 2011). Komponen profil kepala dan leher memiliki bobot 30%. Semakin cembung mukanya maka semakin dicari para penggemar Kambing Kaligesing. Demikian pula dengan gelambir, semakin bergelambir semakin menarik. Komponen ukuran telinga memiliki bobot 15% dari total penilaian. Ukuran telinga memberikan kontribusi bobot terhadap penilaian keseluruhan dari seekor Kambing Kaligesing karena merupakan ciri khas Kambing PE dan Kambing Kaligesing. Semakin panjang dan lebar telinga kambing, maka semakin tinggi skor nilai yang diperoleh.

Abstract

CASREA is protein supplement (PS) based on extruded-cassava-urea as main materials.  The objective of this study was to examine the CASREA characteristics by evaluating ammonia concentration (NH3), Volatile fatty acids (VFA), rumen microbial protein synthesis (RMPS), and protein digestibility post rumen (PDPR). Variables of NH3, VFA and RMPS were analyzed with a completely randomized design in factorial (4X3), namely CASREA as factor A, consisted of: Casrea1 (made from 32% urea and 58% cassava without extrusion), Casrea2 (extrusion 22% urea and 68% cassava), Casrea3 (extrusion 27% urea and 63% cassava), and Casrea4 (extrusion 32% urea and 58% cassava), whereas the factor B was incubation times, consisted of  2, 4, and 6 hours incubation time. Variable of PDPR was analyzed with a completely randomized design, and the treatments were Casrea1, 2, 3, and 4. Results showed that there were no interactions between CASREA and incubation time on variables of NH3, VFA, and RMPS. Extrusion on CASREA materials reduced (P<0.05) NH3 and VFA, but increased (P<0.05) RMPS and PDPR.  The highest RMPS and PDPR were 29.04 mg and 76.16%, respectively and were attained by Casrea2.  Casrea1 had the highest NH3 (43.42 mM), whereas Casrea2 had the lowest (29.65 mM).  Meanwhile, NH3 caused by Casrea2, Casrea3, and Casrea4 was 29.65, 30.54 and 31.44 mM, respectively and the increase these values were not significantly different. The concentration of NH3, VFA, and RMPS were stable on 4 hours incubation time. The present findings suggest that CASREA made from extrusion of 22% urea and 68% cassava as main materials was PS for slow release of ammonia (SRA) in the rumen due to reduction of NH3, but it improved the utilization of nitrogen for rumen microbial protein synthesis.  (Animal Production 10(1): 34-41 (2008) Key Words: Extruded-cassava-urea, protein supplement, slow release of ammonia
