Abstract

ABSTRACT. Penelitian bertujuan untuk mengkaji perkembangan bakteri usus halus dan performan ayam kampung silangan kampung-leghorn (KL) akibat ditambahkan ekstrak umbi dahlia dalam ransum. Ternak percobaan yang digunakan adalah persilangan ayam kampung silangan KL sebanyak 200 ekor umur 22 hari dengan rata-rata bobot badan 180,46 1,21 g. Bahan perlakuan meliputi umbi dahlia, ethanol 70%, kertas saring halus serta bahan pakan penyusun ransum (jagung giling, bekatul, bungkil kedelai, tepung ikan, CaCO3 dan mineral dan vitamin mix). Rancangan percobaan yang digunakan rancangan acak lengkap dengan 4 perlakuan dan 5 ulangan (masing-masing unit percobaan diisi 10 ekor). Perlakuan yang diterapkan meliputi: P0=Ransum kontrol/RK, P1=RK+0,39% ekstrak umbi dahlia, P2=RK+0,78 ekstrak umbi dahlia, dan P3= RK+1,17 ekstrak umbi dahlia. Parameter yang diukur meliputi populasi bakteri asam laktat, Escherichia coli, pH digesta tiap masing-masing segmen usus halus dan pertambahan bobot badan harian (PBBH). Data dianalisis dengan menggunakan uji sidik ragam dan jika berpengaruh nyata dilakukan uji beda nyata Duncan pada taraf 5%. Hasil penelitian menunjukkan bahwa penambahan ekstrak umbi dahlia berpengaruh nyata terhadap populasi bakteri asam laktat, Escherichia coli, pH digesta tiap masing-masing segmen usus halus dan PBBH. Kesimpulan adalah penambahan ekstrak umbi dahlia sampai taraf 1,17% sebagai sumber inulin di dalam ransum dapat meningkatkan populasi bakteri asam laktat, menurunkan pH dan Escherichia coli pada masing-masing segmen usus halus serta memperlambat laju digesta dan meningkatkan PBBH. (Population of small intestine bacteria and performance of native chicken-leghorn crossbreed duo to feeding of dahlia tuber extract) ABSTRAK. This study aims to examine the development of small intestine bacteria and the performances of native chicken-leghorn crossbreed due to the addition of dahlia tuber extract in the diet. Experimental animals were 200 unsex native chicken-leghorn crossbreed, 22 days old with an average body weight of 180.46 1.21 g. Treatment materials include dahlia tuber, ethanol 70%, fine filter paper and feed stuff (yellow corn, rice bran, soy bean meal, fish meal, CaCO3, and vitamin-mineral mix). The present experiment was assigned in a completely randomized with 4 treatments and 5 replications (10 birds each). The treatments were: P0=Control Diet/CD, P1=CD+0,39% dahlia tuber extract, P2=CD+0,78% dahlia tuber extract and P3=CD+1,17% dahlia tuber extract. Parameters measured were the number of Lactic Acid Bacteria (LAB), Escherichia coli, intestinal potential hydrogen (pH) (duodenal, jejunal and ileal), rate of passage and daily body weight gain (DBWG). Data were subjected to ANOVA and followed by Duncan Multiple Range Test on 5% level. The results indicated that feeding native chicken-leghorn crossbreed with the diet containing dahlia tuber extract (DTE) significantly (P0.05) increased LAB population and DBWG, decreased E. coli population and intestinal pH, and slow the rate of passage down. In conclusion, feeding of dahlia tubers as a source of inulin in the form of dahlia tuber extract to a level of 1.17% increased the population of lactic acid bacteria, reduced pH and Escherichia coli in each segment of the small intestine and retard the rate of digestion and increased body weight gain.

Abstract

Evaluation of metabolic energy value of roasted sorghum in culled laying chickensABSTRACT. Tannin contained in sorghum can be reduced by using technology processing such as roasting. By using this way, husk of sorghum can be removed leading to decrease of tannin content which is reflected by the value of metabolism energy. The purpose of this experiment is to investigate the effect of roasted sorghum on metabolism energy of culled laying chickens. Measurement of metabolic energy as mathematic is used as comparison. The material used in his experiment was red sorghum, water, and 39 culled laying chickens. Equipment used in this experiment was balance, roasting tool, plastic, force feeding equipment, metabolism cages and bomb calori-meter. This experiment used completely randomized design consisting of 4 treatments and 4 replications (each replication 3 chickens). Treatment consisted of T0 = no roasted sorghum, T1 = roasted for 5 minutes and T2 = roasted for 10 minutes. Data collected were metabolism energy of roasted sorghum both biologically (force feeding) and mathematically (proximate analysis) at culled laying chickens. All data were statistically calculated, further statistically was conducted by using Duncan and compression of metabolism energy was calculated by using t-Test. The results show that, no statistically effect (p0, 05) on duration of roasting on metabolism energy of sorghum. Based on t-Test analysis, there was a significantly difference (p0, 05) between biological metabolism and mathematical metabolism. From this experiment, it can be concluded that 10 minutes of roasting cannot increase of sorghum metabolic energy. The average of biological metabolic was lower (3105, 94 kcal/kg) compared to the average of mathematical metabolic energy (3766, 82 kcal/kg).
