Abstract

This study was conducted to investigate the effectiveness of Lactobacillus sp and fructooligosaccaride (FOS) to reduce the volatile ammonia formation from chicken excreta and layer slurry. For each treatment-replication, 150 g of fecal material were collected from the poultry farm and placed in 500 ml beaker glass. The fecal sample was then treated with 2% Lactobacillus sp (2.6x106) cfu/g and 2% FOS and covered with plastic wraps. The volatile ammonia contents and pH were measured after one hour of standing (0 d) and repeated at 48 h intervals for 6 d. For the dropping slurry study, 300 g of each layer dropping slurry sample were used. Results indicated that 2% Lactobacillus sp or FOS supplementations in the feces and dropping slurry after 1 h up to 6 d reduced the ammonia odor formation, fecal pH, and moisture content. The Lactobacillus sp and FOS treated manure resulted in increasing  Lactobacillus sp count and reducing in E. coli, Salmonella, and Campylobacter in 6 days for both feces and layer dropping slurry. In addition, reducing moisture content was observed in treated manure. It is concluded that Lactobacillus sp and FOS reduced the volatile ammonia formation and pathogenic bacteria from chicken excreta and layer slurry.

Abstract

The experiment  was conducted in two phases.  The first experiment was to observe the effectivity  of six  culture of Bacillus and Lactobacillus bacteria for reducing fecal ammonia.  The second experiment was to evaluate the application of Bacillus and Lactobacillus bacteria as probiotic for reducing ammonia feses and litter in broiler chicken house and observe its effect on the performance. Six bacteria culture consisting of three species of Bacillus bacteria (Bacillus subtilis, Bacillus cereus and Bacillus thuringiensis) and three species of Lactobacillus bacteria (Lactobacillus acidophillus, Lactobacillus bulgaricus and Streptococcus thermophillus) were used in the first experiment and 200 Day Old Chicks CP 707 were used in application of probiotic at the second  experiment.  Probiotic treatment were administered by drinking water, sprayed on the litter, combination of drinking water and spraying, and without probiotic as the control. The result of the first experiment showed that the six bacterial cultures and their combination significantly (P<0, 05) reduced feses ammonia and pH. The result of the second experiment showed that the probiotic treatment was significantly (P<0, 05) reduced ammonia of fresh fecal and litter, but was not significantly improving the performance of the chickens. The conclusion of this experiment was that the combination of six bacterial cultures of Bacillus and  Lactobacillus as probiotic was effective to reduce ammonia pollution in poultry house

Abstract

Penelitian ini bertujuan bakteri Bacillus amyloliquefaciens dapat mengurangi pencemaran amonia pada kandang ayam broiler. Metode penelitian yang digunakan adalah eksperimental menggunakan Rancangan Acak Lengkap Pola Faktorial 3x 3 dengan 3 ulangan dan 2 faktor. Faktor A level energi (H1 3000 kkal/kg), (H2 2900 kkal/kg), (H3 2800 kkal/kg). Faktor B level protein (R1 22 %), (R2 20 %) dan (R3 18%). Parameter yang diukur adalah Kadar ammonia, kadar air ammonia dan pH ammonia. Hasil penelitian menunjukan kombinasi level energi dan level protein serta interaksi kedua faktor signifikan (P< 0,05) terhadap kadar ammonia, kadar air dan pH ammonia. Hasil penelitian ini dapat disimpulkan bahwa kombinasi energi protein yaitu 2800 kkal/kg : 18% dan bakteri Bacillus amyloliquefaciens lebih efektif untuk mengurangi pencemaran amonia pada kandang ayam broiler.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan multienzim dalam ransum yang mengandung bungkil inti sawitterhadap performa pertumbuhan dan morfometrik usus halus pada broiler.Penelitian menggunakan 112 ekor DOC broiler, multienzim komersil Solagri-3 yang merupakan kombinasi beberapa enzim unggulan, yaitu enzim amylase, cellulase, glukanase, pectinase, phytase, protease dan xilanase.Ransum disusun dengan kandungan bungkil inti sawit sebanyak 30% dan disuplementasi dengan 3 (tiga) level multienzim Solagri-3 yaitu 0.03%, 0.06% dan 0.09%. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 4 ulangan, tiap ulangan terdiri dari 7 ekor ayam. Perlakuan yang diujikan terdiri dari; P0= Ransum basal (kontrol), P1= P0 + 0.03% Solagri-3, P2= P0+ 0.06% Solagri-3 dan P3= P0+ 0.09% Solagri-3. Peubah yang diamati adalah konsumsi ransum, pertambahan bobot badan, konversi ransum, karkasrelatif, persentase hati,pancreas, gizard, bobot dan panjangusus halus sertabagian-bagiannya. Data dianalisis sesuai rancangan dan jika terdapat pengaruh yang nyata akan dilanjutkan dengan Uji Duncan (Steel dan Torrie, 1993). Hasil analisis ragam menunjukkan bahwa penambahan multienzim berpengaruh tidak nyata (P>0.05) terhadap konsumsi, pertambahan bobot badan, konversi ransum, persentase hati, pancreas dan gizzard. Penambahan multienzim berpengaruh nyata (P<0.05) terhadap bobot karkas, persentase bobot dan panjang usus halus. Uji Duncan menunjukkan bahwa penambahan multienzim Berpengaruh nyata (P<0.05) dapat meningkatkan bobot relatif karkas, persentase bobot dan panjang usus halus. Kesimpulan dari penelitian ini adalah penambahan multienzim solagri-3 dalam ransum yang mengandung BIS 30% sebanyak 0.06% dalam ransum dapat meningkatkan bobot karkas dan usus halus pada broiler.

Abstract

Biofuel is an alternative energy to replace fossil fuels. The most popular form of biofuel today is bioethanol. Biofuels are considered as a suitable alternative to fossil fuels because they are more environmentally friendly. Production of bioethanol utilizing thermophilic microorganisms is more profitable because thermophilic microbes generally have the characteristics of being able to use a variety of substrates, low contamination, and resistance to high temperatures. The use of microbial consortia tends to give better results than the use of monoculture isolates to optimize bioethanol yields. The aim of this study was to determine the compatibility and ability of the best thermophilic bacterial triculture consortium from the Mudiak Sapan hot springs in producing biofuel. This research is a descriptive research, to test isolates of a consortium of thermophilic bacteria that produce bioethanol. The results of this study showed that consortium isolates tended to give better results than monoculture isolates. The best thermophilic bacterial triculture consortium from the Mudiak Sapan hot springs in producing biofuels namely MS 12, 17, 18 produced a bioethanol content of 0.863%.
