Abstract

The experiment was conducted to evaluate physical quality of meat in broiler fed diets with addition of tapioca by-product and tofu waste fermented with a combination Aspergillus niger and Rhizopus oligosporus as a substitution for corn. Two hundred DOC’s unsex Lohmann Platinum strain were randomly divided into 25 groups containing eight birds each. Experiment was designed by using “Completely Randomized Design” with five treatments, replicated five times. The treatments of feed used were P0 = basal diet + corn P1 = basal diet + Corn subtituted 5% OAF, P2 = basal diet + Corn subtituted 10% OAF, P3 = basal diet + Corn subtituted 15% OAF, P4 = basal diet + Corn subtituted 20% OAF. Chickens were raised for 35 days. Drinking water and feed were given ad libitum. Meat samples (Pectoralis superficialis) were taken to determine the physical qualities of meat. The results showed that addition of OAF did not exertisignificant effect on carcass presentage, pH, water-holding capacity, and cooking loss of meat of broiler. The conclusion was that the additional of OAF cannot improve the quality of physical broiler meat. The best result showed at third treatment with 15% OAF substitution of feed.

Abstract

Quail (Coturnix japonica) is a bird that have high protein content, but vulnerable to digestive diseases. The purpose of this research was to determine the ability of antibacterial compounds of LAB from intestinal quail origin in bacterial growth inhibition test. This research used Completely Randomized Design (CRD) with variable concentrations of Cell Free Supernatant (CFS) for 10, 20, 30, 40, 50, and 60% and bacterial pathogens of the digestive tract of quail (S. typhimurium, E. coli of human origin, and E. coli of bird origin) by using the Minimum inhibitory Concentration (MIC) and Minimal Bactericidal Concentration (MBC). The data obtained were analyzed by Analysis of Variance (ANOVA). The results obtained showed that the bacterium Lactobacillus fermentum and L. salivarius derived from quail intestine can produce antibacterial compounds that could inhibit the growth of Salmonella typhimurium, Escherichia coli (human), and E. coli (bird). Minimum concentration of the addition of CFS from L. fermentum in inhibiting the growth of tested bacteria was 30% for S. typhimurium, 30% for E. coli (human), and 20% for E. coli (bird). While the addition of CFS minimum concentration of L. salivarius in inhibiting the growth of tested bacteria was 20% for S. typhimurium, 20% for E. coli (human), and 10% for E. coli (bird). Keywords: Antibacterials, Lactic Acid Bacteria (LAB), Escherichia coli, Quail, and Salmonella typhimurium.

Abstract

The experiment was conducted to evaluate the production performance and egg quality of laying hens supplemented with phytobiotics and magnetized drinking water. This experiment used 2700 gauss level in Magnetized Drinking Water (MDW). The phytobiotics had two form: the non-encapsulated phytobiotics (PTO) and encapsulated phytobiotics (EPTO). There were untreated water (control) and the treated water (MDW, PTO, PTO+MDW, EPTO, EPTO+MDW). The treatments were presented by 0.6% for each treatment. The result showed highly significant (p<0.01) improvement on feed conversion ratio (FCR) but no significant effect on other production performance variables including feed intake, hen day production (HDP), egg mass, and income over feed cost (IOFC). The results indicated a highly significant improvement (p<0.01) on egg weight and yolk cholesterol. There were no significant effects on shape index (SI), shell weight, shell thickness, Haugh unit (HU), albumen height, yolk weight, yolk index (YI), and yolk color of egg quality variables. It was concluded that the encapsulated form (EPTO and EPTO+MDW) had the best improvement on FCR and yolk cholesterol, on another hand the non-encapsulated form (PTO and PTO+MDW) increased the egg weight of laying hens

Abstract

The research was aimed to evaluate the effect of biogas liquid waste as a fermentation starter of rice husk to the nutrient content, gross energy and bulk density. The method used laboratory experiment using a completely randomized design (CRD) on factorial pattern (6 x 5) with the level of biogas waste liquid : P0-treatment (0% negative control), P0+ (Cellulomonas sp as positive control), P1 (5%), P2 (10%), P3 (15%), P4 (20%) ml/g, and the incubation time : T0 (0 day control ), T1(7 days), T2 (14 days), T3 (21 days) and T4 (28 days). The variables measured was the content of ash, crude protein, crude fiber, crude fat, gross energy and bulk density. Data were analyzed by analysis of variance (anova) CRD Factorial pattern and if there is a significant difference was followed by Duncan's Multiple Range Test. The results of research was the level of biogas liquid waste and the incubation time provides a significant influence (P<0.01) on the nutrient content, gross energy and bulk density of rice husk. The interaction level liquid waste provision of biogas and incubation time was highly significant (P<0.01) on the nutrient content, gross energy and bulk density. It can be concluded that the addition of biogas liquid waste 15% (ml/g) with a time of incubation for 21 days have best rice husk quality content based on improvement of crude protein, crude fat, and gross energy with lowest crude fiber.

Abstract

Abstract This study aims to improve the nutritional quality of venison floss by modifying the the technology process of floss making with adding red fruit oil (Pandanus conoideus L) and kebar grass extract (Biophytum petersianum) as a source of natural antioxidants. The results showed that the nutritional value of floss was influenced by the use of these herbal. Supplementation of antioxidant is to potentially extend the shelf-life of floss as indicated in decreasing the value of water activity (Aw) and thiobarburic acid (TBA). The Aw value decreased from 0.756 to 0.701, and TBA decreased from 0.139 to 0.055 mg/kg. The protein of floss increased from 33.20 to 35.60%. The result also showed that the content of antioxidant increased which is indicated by the increasing of beta-carotene content from 0.0087 mg /100 gram to 0.81 mg/100 gram. Results also showed that the use of red fruit oil extract and kebar grass extract decreased the content of saturated fatty acids, meanwhile in unsaturated fatty acids it increased arachidonic fatty acids. Keywords: Antioxidant; Beta-caroten; Kebar grass; Red-fruit oil; Venison floss. Abstrak Penelitian ini bertujuan meningkatkan kualitas nutrisi abon daging rusa dengan memodifikasi proses teknologi produksinya dengan penambahan ekstrak minyak buah merah (Pandanus conoideus L) dan ekstrak rumput kebar (Biophytum petersianum) sebagai sumber antioksidan alami. Hasil penelitian memperlihatkan bahwa nilai nutrisi produk olahan daging dipengaruhi oleh adanya penambahan senyawa antioksidan. Pemberian suplementasi bahan sumber antioksidan meningkatkan daya awet pada abon yang ditunjukkan dengan penurunan nilai aktivitas air (Aw) dan nilai thiobarburic acid (TBA). Nilai Aw abon menurun dari 0,756 menjadi 0,701, dan nilai TBA-nya menurun dari 0,139 menjadi 0,055 mg/kg. Nilai nutrisi terjadi pada nilai protein yang meningkat dari 33,20 menjadi 35,60%. Sebagai sumber antioksidan terlihat pada peningkatan kandungan beta-karoten dari 0,0087 mg/100 gram menjadi 0,81 mg/100 gram. Faktor penting lainnya dengan penggunaan ekstrak minyak buah merah dan ekstrak rumput kebar yakni adanya penurunan yang signifikan pada kandungan asam-asam lemak jenuh, akan tetapi pada asam-asam lemak tidak jenuh terjadi peningkatan pada asam lemak arakidonat. Kata kunci: Abon rusa; Beta-karoten; Herbal antioksidant; Minyak buah-merah; Rumput kebar.
