Abstract

The objective of this research was to analyze the effect of coconut sugar paste in naturally fermented trash fish ensilage on chemical change. Grinded trash fish (Pomadasys macullatus) was mixed with coconut sugar paste (0, 15, 30 and 45%/kg fresh trash fish) without inoculation in plastic bag. Anaerobe incubation was conducted at room temperature (29°±1°C). Chemical change (pH, lactic acid, ammonia, non-protein nitrogen, peroxide value and free fatty acid) was observed during fermentation period of 0, 4, 8, 12, 20 and 24 days. The experiment which had a completely randomized design to select the best amount of coconut sugar paste and fermentation period in trash fish ensilage. Fresh trash fish and fermentation product (trash fish silage) determined by the proximate analysis (dry matter, ash, crude protein and crude fat). Result indicated that the pH decreased remained constan at 4,4 after 16-day fermentation. Lactic acid, ammonia, non-protein nitrogen, peroxide value and free fatty acid during fermentation significantly increased due to different levels of coconut sugar paste and fe rmentation period. Conclusively, coconut sugar paste at the level of 15%/kg fresh trash fish was the best combination in natural fermentation with 16-day fermentation period and the product was potential protein source (45% DM) for animal feed. Key word: Trash fish, coconut sugar paste, silage, fermentation.

Abstract

Abstract.  On farm level, the price of milk is affected by its fat content. On the other hand, improving milk quality by the use of better ration economically is not feasible. The problem is how to find an appropriate, easily found, relatively cheap and efficient ration for producing better quantity and quality of milk. An experimental research was conducted using Saccharomyces cerevisiae yeast in lactating dairy cows ration, in a  4x4 Latin Square Design, with animal trial as column and trial period as row. Each trial period consisted of 14-day preliminary and 7-day trial period (collection period). The treatment to be tested were four levels of yeast addition, namely : 0, 5, 10 and 15 g/cow/day. The variables measured were daily milk production (4% FCM) and milk composition (solid non fat, fat, protein, lactose). The result showed that the addition of yeast had no significant effect on milk production and milk composition, but tended to increase milk fat in which the highest fat content of 5.13 % was achieved when 8.5 g/cow/day was suplemented. The average milk production, solid non fat, lactose, fat, and protein were 9.55 kg/day, 8.70%, 3.99%, 4.50% and 0.13%, respectively. Based on all measured variables, it can be concluded that the addition of yeast Saccharomyces cerevisiae up to 15 g/cow/day to lactating dairy cows ration did not effectively improve milk production and milk composition. Key words: yeast addition, milk production, milk composition. Abstrak.  Penentuan harga susu di tingkat peternak sangat dipengaruhi oleh kadar lemak susu. Perbaikan komposisi susu dengan peningkatan kualitas pakan sulit dilakukan, karena tidak ekonomis. Oleh karena itu perlu dicari ransum yang murah, mudah didapat dan efisien untuk meningkatkan produksi dan komposisi susu. Suatu penelitian telah dilakukan dengan menggunakan ragi Saccharomyces cerevisiae dalam ransum sapi perah laktasi. Penelitian dilaksanakan dengan metode eksperimental, menggunakan Rancangan Bujur Sangkar Latin 4x4. Hewan percobaan sebagai kolom dan periode percobaan sebagai lajur. Setiap periode percobaan terdiri atas 14 hari masa preliminari dan 7 hari percobaan (masa koleksi). Perlakuan yang diuji adalah 4 taraf penambahan ragi Saccharomyces cerevisiae : 0, 5, 10, dan 15 gr/ekor/hari. Peubah respon yang diamati adalah produksi susu harian (4% FCM) dan komposisi susu (BKTL=Bahan Kering Tanpa Lemak, lemak, protein dan laktosa).  Hasil penelitian menunjukkan bahwa penambahan ragi tidak berpengaruh nyata terhadap produksi 4% FCM (Fat Corrected Milk) maupun komposisi susu, tetapi cenderung meningkatkan lemak susu dan mencapai kadar tertinggi 5,13% pada penambahan ragi 8,50 g/ekor/hari. Rataan produksi susu 9,55 kg/hari, BKTL (Bahan Kering Tanpa Lemak) 8,70 %, laktosa 3,99%, lemak 4,50% dan protein 0,13%. Berdasarkan semua peubah respon yang diukur dapat disimpulkan bahwa penambahan ragi Saccharomyces cerevisiae sampai 15 gr/ekor/hari belum berhasil memperbaiki produksi dan komposisi susu. Kata kunci : penambahan ragi, produksi susu, komposisi susu.

Abstract

Two plants as condensed tannin (CT) sources were supplemented to protein trash fish silage (TFS) to observe their effect on in vitro ruminal fermentation product, micobial protein synthesis, and   digestibility. CT supplementation on protein trash fish silage was on control proportion (0), under optimum level (2.0%), at optimum level (4.0%), and above optimum level (6.0%) of g TFS); of protein precipitation of bovine serum albumin (BSA) with CT from L. leucocephala; and under optimum level (1.5%), at optimum level (3.0%) and above optimum level (4.5% of g TFS), BSA protein precipitation with CT from C. calothyrsus. The effect on degradation in ruminal fluid and ruminal fluid followed by incubation in HCl-pepsin was evaluated using a modified two-step in vitro method. The CT level of L. leucocephala and C. calothyrsus was 4% and 6%, respectively with protein precipitation BSA was 26.25 and 31.77 g BSA/g CT, respectively. CT supplementation to trash fish silage, ruminal fermentation product (NH3-N, C2, C3, and total VFAs) and digestibility (DM and OM) decreased (P<0.01) and increased (P<0.01) total CP digestibility (in HCl-pepsin). The difference was attributed to CT source without affecting ruminal microbial protein synthesis. CT of L. leucocephala was better in increasing total protein digestibility (70%) than that of C. calothyrsus  (15%). It indicated that CT of C. calothyrsus was less effective in protected TSF protein degradation in rumen compared to that of L. leucocephala.

Abstract

The objectives of the research were to supply nitrogen for protein synthesis of ruminal microbe from slow release urea and to supply post-rumen protein from soybean meal protected with condensed tannin (CT) from crude Leucaena leaves extract. In Experiment 1, slow release urea (SRU) was made by extrusion of cassava waste-urea, tapioca meal-urea and cassava meal-urea. Evaluation of SRU properties was based on residual nitrogen concentration and ruminal fermentation products (total volatile fatty acid and ammonia-nitrogen) in vitro. In Experiment 2, soybean meal protected with CT from crude Leucaena leaves extract as much as 1,68 g tannin/100 g DM soybean meal. SRU that was selected from Experiment 1 was used as the supplement in sheep ration whose protein source was protected with CT. SRU supplement in basal rations was 0, 6.36, 12.75, 19.11% DM. In vitro result in Experiment 1, showed that SRU of cassava waste, tapioca meal and cassava meal were different (P<0,01) on residual nitrogen content, total VFA, ammonia-N, and fermentation time. The optimum SRU obtained from cassava waste by inhibiting nitrogen hydrolysis up to 14 h. In Experiment 2, SRU supplementation of cassava waste on basal ration whose protein source was protected with CT increased dry matter (DM) degradability (P<0,01), total VFA (P<0,01), ammonia-N (P<0,01), and did not affect crude protein (CP) ruminal degradation. Post-ruminal degradability of DM and CP increased (P<0.01) in line with the increasing supplement, and reached the optimum level at 12,75 – 19,11% DM. In conclusion, cassava waste was a potent SRU through extrusion process and could be harnessed as SRU supplement in ration with protein source protected with condensed tannin to improve ruminal microbe protein synthesis.

Abstract

This study was aimed to evaluate the use of safflower oil (Carthamus tinctorius L) and inositol on the digestive profile of male Sentul chickens. A total of 182 Sentul chickens aged 17 weeks were reared up to 23 weeks in 91 units of battery cage (6 chickens/unit). The research was conducted in a Completely Randomized Design (CRD) with nine treatments and three replicates (6 chickens/replicate). The research treatments were R0 = control/ basal feed + 0% Safflower and 0% Inositol; R1 = Basal feed + 0.5% Safflower oil; R2 = Basal feed + 1.0% Safflower oil; R3 = Basal feed + 0.5% Inositol; R4 = Basal feed + 1.0% Inositol; R5 = Basal feed + 0.5% Safflower oil and 0.5% Inositol; R6 = Basal feed + 0.5% Safflower oil and 1.0% Inositol; R7 = Basal feed + 1.0% Safflower oil and 0.5% Inositol; R8 = Basal feed + 1.0% Safflower oil and 1.0% Inositol. Basal feed was composed of corn, rice bran, soybean kernel, fishmeal, palm oil, calcium carbonate (CaCO3), topmix, lysine, and methionine, as well as safflower oil (Carthamus tinctorius L) and inositol. The measured variable consists of digestive profile (the percentage of intestine weight, digesta, proventriculus, gizzard) and intestine length, crypt depth, the width and length of intestinal villi, Intestinal histology profile. The data were subjected to a statistical analysis of variance (ANOVA) continued with an Honestly Significant Difference test (HSD). The result showed that incorporating safflower oil (Carthamus tinctorius L) and inositol into feed did not significantly affect (P>0.05) the digestive profile of Male Sentul chickens. Conclusively, safflower oil and inositol up to 1% in the feed are safe for male Sentul chickens without interfering with the performance of digestive organs because it produces relatively similar intestinal weight and length, crypt depth, as well as the length and width of intestinal villi.

Abstract

The study was aimed to examine effect of protecting soybean meal using mahogany leaf extract on rumen fermentation products in vitro. The material used was cow rumen fluid, basal ration consisting of concentrate and elephant grass with a ratio of 60:40%, and mahogany leaves. The research was carried out in three stages: mahogany extraction, protein protection using mahogany extract, and in vitro stages. The test was conducted in vitro based on a completely randomized design (CRD). The treatments consisted of 4 kinds of soybean meal protection with 0% tannin concentration (T0); 1.5% (T1); 3% (T2); and 4.5% (T3). Data obtained were analyzed by analysis of variance and tested using orthogonal polynomials. Results showed that  addition of protected soybean meal with mahogany leaf extract had a cubical effect on partial VFA, methane gas and post-rumen dissolved protein, a quadratic effect on protozoa, and a linear effecton N-NH3, SPM, and RUDP. Giving extra mahogany leaves at a level of 1.5% produced a fermented product that was not different from the control while giving a level of 3% got the highest fermentation product. Giving mahogany leaf extract at a level of 4.5% resulted in the highest SPM, and RUDP but there was a decrease in soluble protein, which indicated the occurrence of overprotection. The addition of 3% mahogany leaf extract effectively increased rumen fermentation products, RUDP, and soluble protein without disturbing the activity of rumen bacteria.
