  Background and Objective: The utilization of oil palm fronds (OPFs) as feed is limited due to their high lignin content. The biodelignification of OPFs with Phanerochaete chrysosporium plus the elements Ca and Mn can break down lignocellulose and lignin hemicellulose bonds. Supplementation of fermented oil palm fronds (FOPFs) with P, S and Mg results in the highest microbial protein synthesis and VFA concentration. The objective of this study was to evaluate the effect of supplementation with phosphorus, sulfur and magnesium in goat rations containing fermented oil palm fronds (FOPFs; fermented by Phanerochaete chrysosporium) on nutrient digestibility. Materials and Methods: This research was carried out using a randomized block design with 5 treatments and 3 replications. The following treatments were performed: A = 40% Napier grass (NG)+0% FOPFs+60% concentrate; B = 20% NG+20% FOPFs+60% concentrate; C = 0% NG+40% FOPFs+60% concentrate; D = 20% NG+20% FOPFs +60% concentrate plus P, S and Mg and E = 0% NG+40% FOPFs+60% concentrate plus P, S and Mg. The data were analyzed using a one-way analysis of variance (ANOVA) and differences between treatments were tested using Duncan's multiple range test (DMRT).The observed parameters were digestibility of the nutrients. Results: Supplementation with phosphorus, sulfur and magnesium in goat rations that contained fermented oil palm fronds by Phanerochaete chrysosporium at concentrations of 40 and 60% resulted in the highest digestibility of the nutrients. Conclusion: Supplementation with P, S and Mg in goat rations containing FOPFs is indispensable for the growth and activity of rumen microbes.

  Palm manufacture industry has produced many kinds of by products which can potentially be a feedstuffs such as Palm Kernel Cake (PKC), Palm Oil Sludge (POS) and Palm Press Fiber (PPF). From the whole result of production, only 40% of products from palm which can be used for human’s consumption, while 60% is the by product which can potentially be feedstuffs. In 2008, the area of palm plantation in Indonesia reaches 7.3 millions of Ha with the production reaches 19.2 millions of ton and on 2009, the area of palm reaches 7.9 million of Ha with the production of 19.4 millions of ton (PTPN, 2009). From those productions above, the potential of by product of palm manufacture industry which will be produced and used as feedstuffs is really big. The aim of the research was conducted rumen’s fluid characteristics of ettawa goat given ration by paoducts of palm industry. The matter used on this experiment was by products of palm industry which consists of PKC, POS and PPF which can be formulated in a complete ration with different composition in forage 60% and 40% concentrate. Substrate of complete ration which will be evaluated in in-vitro analysis, was made in the form of flour and the making of medium liquid which consist of macro mineral, micro mineral, resazurin, buffer and Reducing Agent (RA) was pointed to the method of Theodorou and Brooks (1990). The measured variable is the characteristic of rumen’s fluid including total production of gas, pH, rumen’s bacteria, NH3 and VFA throughout 48 h of incubation. The result of experiment showed that the use of by products of palm industry formulated in a complete ration produce the characteristic of rumen’s liquid which still complete the standard, concerned from pH (6.44), total gas production (97.00 ml), the amount of bacteria colony (5.02 x 109 cfu/ml), NH3 (74 mg/l) and VFA (81.68 mM). From the whole parameter above, it can be concluded that the by product of palm industry can be used as feedstuffs and have a big potential to replace substance of conventional ration which is normally used.

  The aim of the current study was to evaluate the increasing doses of OEO extracted from Berastagi orange peels on performance, rumen fermentation and blood metabolites in fattening Bali cattle. Fifteen male Bali beef cattle of similar age 1.5-2 years and initial body weight (194.4±22.31 kg) were used in a Completely Randomized Block Design (RCBD) for 90 d. The doses of OEO supplementation ware applied by oral infusion. Dose of the OEO supplementation treatments were: 0 ppm (basal diet + 0 ppm OEO/kg DMI), 200 ppm (basal diet + 200 ppm OEO/kg DMI), 400 ppm (basal diet + 400 ppm OEO/kg DMI), 800 ppm (basal diet + 800 ppm OEO/kg DMI) and 1200 ppm (basal diet + 1200 ppm OEO/kg DMI). The basal diets were formulated based on protein and TDN content of 13 and 65% with swamp grass: concentrate ratio of 60: 40%. Swamp grass and concentrate were given separately. The animal were fed twice a day, morning and afternoon. Oral infusion of OEO treatments were given after the animal fed a morning of concentrate using disposable syringe. The obtained result showed that the increasing doses of OEO did not influence on final BW, DMI, ADG and FCR. OEO supplementation was significantly (p<0.05) decreased on ruminal NH3-N, molar proportion of acetate and ratio acetate to propionate, whereas total VFA and molar proportion of propionate tended to increase. Supplementation of OEO at the dose 800 ppm and 1200 ppm was tended to decrease of total VFA and molar proportion of propionate. There were no effect of increasing dose of OEO on pH, molar proportion of butyrate, valerate, iso-valerate. Serum concentration of glucose, total triglycerides, albumin were no changed by increasing dose of OEO, but serum total protein tend to increased (p<0.15) by OEO supplementation. Moreover, supplementation of OEO decreasing serum concentration of total cholesterol, LDL, urea and BUN and increasing serum concentration of HDL. Our results suggest that supplementation of berastagi orange oil at dose 400 ppm could be considered as suitable feed additives to manipulate rumen microbial fermentation and to improve blood metabolites in fattening Bali cattle.

  Background and Objective: Manure accumulation in open areas for long periods of time promotes the synthesis of ammonia (NH3) by microbes and its emission to the atmosphere. Forage plants are used as ammonia trapsin poultry farms. This study aims to evaluate the potential of planting dwarf elephant grass and Gliricidia sepium around poultry farms to trap ammonia. Methodology: This study used a complete randomized design with a 2×3 factorial pattern with 6 replications as follows: Factor A: Two species (Dwarf elephant grass and Gliricidia sepium) and Factor B: The distance of the cages from the laying hen (1.5, 3 and 100 m). The parameters measured were the dry matter forage yield, plant height, protein content, ammonia concentration and in vitro dry matter digestibility. Results: The dry matter production of dwarf elephant grass was higher than that of Gliricidia sepium (0.5 vs 0.24 kg pot–1), but for the other parameters, such as the plant height, protein content and dry matter digestibility, the values for Gliricidia sepium were higher than those for dwarf elephant grass. Regarding the plant’s distance from the cage, a distance of 1.5 m yielded the highest levels of dry matter, forage yield, plant height, protein content and in vitro dry matter digestibility. The ammonia concentration at the cage of the laying hen was 7.7 ppm and at a distance of 3 m was 0.88 ppm. Conclusion: Gliricidia sepium was effective at absorbing air borne NH3. Plants 1.5 m from the laying hen cage showed the best results.

  Background and Objective: Liquid biourine organic fertilizer can affect the physical, chemical and biological fertility of soil. Mycorrhizal biofertilizers can help plants to supply and absorb nutrients, especially phosphorus, which is low in availability in acidic/critical soils. The aim of this study was to characterize, test and prove that the administration of biourine liquid organic fertilizer and Arbuscular mycorrhizal Fungi biofertilizer (AMF) as a biotechnology agent, was able to improve the productivity of ex-coal mine lands and also affect the content of forage fiber feed fractions. Materials and Methods: An experiment using a completely randomized design with 4 types of treatment and 5 repetitions was conducted. The treatments consisted of: (1) Biourine concentration of 0%+AMF 20 g pot–1, (2) Biourine concentration of 15%+AMF 20 g pot–1, (3) Biourine concentration of 30%+AMF 20 g pot–1 and (4) Biourine concentration of 45%+AMF 20 g pot–1. Variables observed were Acid Detergent Fiber (ADF), Neutral Detergent Fiber (NDF), hemicellulose, cellulose and lignin. Results: The results of various analyses showed that the treatment had a highly significant effect (p<0.01) on all variables observed. The treatment with 45% biourine+AMF 20 g pot–1 resulted in lower ADF, NDF and lignin contents and produced higher cellulose and hemicellulose content than the treatments with 30% biourine+AMF 20 g pot–1, 15% biourine+AMF 20 g pot–1 and 0% biourine+AMF 20 g pot–1. Conclusion: Biourine liquid organic fertilizer and Arbuscular mycorrhizal Fungi biofertilizer (AMF) are biotechnology agents that improve the productivity of ex-coal mine land and also affect the content of forage fiber feed fractions.
