Abstract

ABSTRAK Penelitian bertujuan untuk mengetahui pengaruh level penambahan tanin daun mangrove untuk memproteksi protein ampas kecap terhadap konsentrasi amonia (NH3), produksi protein total dan persentase rumen undegraded dietary protein (RUDP) secara in vitro. Materi yang digunakan adalah ampas kecap, daun mangrove sebagai sumber tanin alami, cairan rumen dan reagensia yang digunakan dalam analisis NH3, protein total dan RUDP. Parameter yang diamati adalah konsentrasi NH3, produksi protein total dan persentase RUDP. Penelitian dilaksanakan menggunakan Rancangan Acak Lengkap dengan 4 perlakuan dan 4 ulangan. Perlakuan adalah T0 (ampas kecap + tanpa tanin), T1 (ampas kecap + tanin 0,25%), T2 (ampas kecap + tanin 0,50%), T3 (ampas kecap + tanin 0,75%). Hasil penelitian diolah secara statistik dengan analisis sidik ragam dan jika terdapat pengaruh nyata akibat perlakuan dilanjutkan dengan uji Duncan dengan taraf 5% untuk mengetahui adanya perbedaan pengaruh antar perlakuan. Hasil penelitian didapatkan konsentrasi NH3 protein ampas kecap terproteksi dengan perbedaan aras tanin berturut-turut adalah 4,34; 3,46; 3,29; 3,10 mM. Produksi protein total yang dihasilkan berturut-turut adalah 315,37; 330,05; 334,04; 304,45 mg/g. Persentase RUDP yang dihasilkan berturut-turut adalah 27,91; 27,96; 28,03; 27,36 %. Hasil uji variansi menunjukkan bahwa proteksi protein ampas kecap menggunakan tanin mangrove berpengaruh terhadap konsentrasi NH3 namun tidak berpengaruh terhadap produksi protein total dan persentase RUDP. Hasil uji lanjut DMRT menunjukkan bahwa konsentrasi NH3 pada perlakuan T0 nyata lebih tinggi (p<0,05) dari T1, T2 dan T3 sedangkan T1, T2 dan T3 tidak berbeda nyata (p>0,05). Dari hasil penelitian dapat disimpulkan bahwa proteksi protein ampas kecap menggunakan tanin daun mangrove terbukti menurunkan konsentrasi amonia (NH3) tetapi tidak mempengaruhi produksi protein total dan persentase RUDPnya.Kata kunci: ampas kecap; tanin; amonia; protein totalABSTRACTThe aimed of this research was to determine the effect of level tannin of mangrove leaf to protected soy pulp protein on ammonia concentration (NH3), total protein production and percentage of rumen undegraded dietary protein (RUDP) in vitro. The material used is soy pulp, mangroves leaves as a natural source of tannins, rumen liquor and reagents used in the analysis of NH3, total protein and RUDP. Parameters measured were NH3 concentrations, total protein production and percentage of RUDP. The experiment was conducted used a completely randomized designed with 4 treatments and 4 replications. Treatments are T0 (soy pulp + without tannin), T1 (soy pulp + tannin 0.25%), T2 (soy pulp + tannin 0.50%), T3 (soy pulp + tannin 0.75%). The results were analyzed statistically by variance analysis, and if there is a real effect due to treatment followed by Duncan test at 5% level to detect a difference between treatment effects. The results obtained NH3 concentration of soy pulp protein protected with different tannin are 4.34; 3.46; 3.29; 3.10 mM. The results total protein production are 315.37; 330.05; 334.04; 304.45 mg/g. The results percentage RUDP are 27.91; 27.96; 28.03; 27.36%. The variant test results showed that the protective soy pulp protein used mangrove tannin significantly decrease NH3 concentrations, but no significantly on total protein production and percentage RUDP. The DMRT test result showed that NH3 concentrations on T0 significantly higher (p<0.05) from T1, T2 and T3 while T1, T2 and T3 not significantly different (p>0.05). From the results of this research concluded that the protection of soy pulp protein used mangrove leaves tannin proven to decrease ammonia concentration (NH3) but did not affected to total protein production and percentage RUDP.Keywords: soy pulp; tannin; ammonia; total protein

Abstract

The study aimed to evaluate the effect of SOYXYL as one of the dietary protected protein supplement product in the rations on the reproduction performance of Simmental bulls. Twelve 5 years-old Simmental bulls were allotted to 4 treatment groups with 3 replications in each, i.e.: T0= control ration (elephant grass + 5 kg/head/day commercial concentrate), T1= control ration + 150 g protected protein supplement SOYXYL (3% of concentrate), T2 = control ration + 300 g SOYXYL (6% of concentrate) and T3= control ration + 450 g SOYXYL (9% of concentrate). The experiment lasted for 90 days. At the end of the experiment, semen and blood were collected and body weight gain was measured. The variables measured included sperm motility, sperm concentration, blood protein, blood urea and the concentration of testosterone. Results showed that SOYXYL supplementation, particularly at the levels of 3 and 6%, increased the total plasma protein of bulls. SOYXYL supplementation at 3% from concentrate resulted in increased plasma urea concentration. Feeding SOYXYL, particularly at the levels of 6 and 9%, increased the average daily gain of bulls as compared to control. Feeding 3% SOYXYL increased, but at the levels of 6 and 9% decreased the concentration of sperm of bulls. The concentration of testosterone was higher in the bulls received 3 and 6% SOYXYL in the rations. Dietary supplementation of SOYXYL increased the sperm motility of Simmental bulls. In conclusion, dietary supplementation of SOYXYL at the level of 3% increased plasma protein, testosterone, and sperm concentrations as well as sperm motility. However, supplementation of SOYXYL at 6 and 9% from rations decreased the concentrations of sperm and testosterone.

Abstract

SOYXYL supplementation as a source of high-quality protected protein in rumen (Rumen Protected Protein) has proven to improve reproduction performance of bulls. The SOYXYL is an extrusion product of soybean (Glycine max) as a source of rumen protected protein. The potential of the protein supplementation is maximally expressed when it is supported by sufficient of metabolic rate. In this case the choline chloride supplementation increases the metabolic rate. The aim of the research was to analyze the effect of choline chloride supplementation on reproduction performance and hematologic status related to reproduction performance of bulls fed protected protein in the ration. The materials used were 12 bulls aged 5 years having weight of 700 ± 2.75 kg that were divided into 4 treatment groups, each of which consisted of 3 heads. The treatments applied were T0 (control): ration (grass + commercial concentrate) + protected protein supplement “SOYXYL”; T1: control + choline chloride 0.145% dry matter (DM) concentrate/head/day; T2: control + choline chloride 0.290% DM concentrate/head/day; T3: control + choline chloride 0.435% DM concentrate/head/day. Variables measured were nutrient consumption, blood lipid status, blood protein status, and reproduction performance. Data were analyzed using ANOVA in a completely randomized design and statistically processed using SAS program. The result showed that choline chloride supplementation by 0.435% from DM concentrate increased (p<0.05) the concentration of blood plasma protein, blood testosterone hormone, sperm concentration, and sperm motility from 6.44 g/dL, 4.66 ng/mL, 1006.74 million/mL, and 36.00%, respectively, in T0 to be 8.57 g/dL, 9.07 ng/ml, 1270.41 million/mL, and 70.00% in T3, respectively. The choline chloride supplementation up to 0.435% from DM concentrate to bulls supplemented with protected protein containing in the ration increased reproduction performance.

Abstract

The purpose of this research was to examine the combination effect of fermentation time by Trichoderma reesei and ammoniation on fiber component of sugar palm pulp. The research used sugar palm pulp from Boyolali which was sun-dried. Sugar palm pulp fermentation with Trichoderma reesei requires nitrogen for microbial growth. Ammoniation process could loose lignocellulosic bonds and provides the nitrogen supply for Trichoderma reesei, therefore these treatments could optimize Trichoderma reesei in the fermentation process. Samples were fermented for 0, 3 and 6 days with 1,5% Trichoderma reesei. The research treatments were allocated according to a completely randomize design with  pattern of 2x3 factorial. First factor was ammoniation treatment and second factor was variation of fermentation time. The parameters observedd were NDF, ADF, hemicellulose, cellulose and lignin. Research result showed that there is was no interactive effect between treatments on reducing levels of NDF and ADF, but interaction treatments decreased (P<0.05) levels of, cellulose and lignin. In conclusion, the interactive effet between fermentation time with Trichoderma reesei and ammoniation reduce levels of hemicellulose, cellulose and lignin in sugar palm pulp.
