Abstract

RINGKASAN Tujuan penelitian ini adalah untuk mengevaluasi apakah probiotik EM-4 berpengaruh positif terhadap performa ternak ayam pedaging, dan apakah probiotik ini dapat menggantikan penggunaan antibiotik Sulfamix. Seratus ekor ayam pedaging (CP 707) umur satu minggu dialokasikan secara acak ke dalam empat kelompok perlakuan, yaitu To = Kontrol (tanpa probiotik), T1 = 3 cc antibiotik Sulfamix dalam 1 l air minum, T2 dan T3 masing-masing 1 cc dan 2 cc probiotik (EM-4) dalam 1 l air minum yang selalu tersedia. Masing-masing perlakuan terdiri atas lima ulangan dengan lima ekor ayam per unitnya. Diberikan pakan komersial dan air minum secara ad libitum sampai ayam berumur enam minggu. Ayam serta pakan yang diberikan dan sisanya ditimbang tiap minggu. Hasil penelitian menunjukkan bahwa pemberian probiotik maupun antibiotik ternyata tidak berpengaruh nyata (P>0,05) terhadap konsumsi ransum, pertambahan berat badan, dan efisiensi penggunaan ransum. Pemberian 1 cc probiotik (T2) memberikan konsumsi ransum dan pertambahan berat badan nyata (P<0,05) lebih tinggi daripada pemberian antibiotik (T1) dan tidak berbeda nyata (P>0,05) dibandingkan dengan kontrol (To). Dari hasil penelitian ini dapat disimpulkan bahwa pemberian antibiotic Sulfamix dalam ransum dan probiotik melalui air minum ternyata tidak berpengaruh terhadap penampilan ayam broiler umur 1-6 minggu. Pemberian probiotik (EM-4) pada dosis 1 cc/1 l air minum ternyata memberikan hasil yang lebih baik daripada pemberian antibiotic.

Abstract

Slow-release urea characteristics of zinc-urea, zeolites-urea, and zeolites-zinc-urea were examined using in vitro techniques. The objective of this experiment was to study the in vitro slow-release urea characteristics of zinc-urea, zeolites-urea, and zeolites-zinc-urea under different molasses concentrations in relation to the ruminal fermentative changes observed in different incubation time. The experimental design employed was randomized block design with a 4 x 3 factorial arrangement plus a control treatment, and conducted in two replications. Factors were various urea sources (urea, zinc-urea, zeolites-urea, and zeolites-zinc-urea) and molasses concentrations (0%, 6%, and 12%) in rice straw based diets. The control treatment was rice straw based diet containing neither urea nor molasses. Diets consisted of 45% rice straw and 55% concentrates (DM basis) were formulated to have similar N and TDN levels. Responses of parameters measured were subjected to MANOVA using the GLM procedure of SPSS 16.00 and differences among mean values, if applicable, were examined using HSD-test. Orthogonal comparisons were used to determine the effects of control treatment vs. various urea sources following significance for the two-factor ANOVA model. Results indicated that zinc-urea, zeolites-urea, and zeolites-zinc-urea under different molasses concentrations contained in rice straw based diets decreased ruminal ammonia up to 48 hours incubation, controlled total VFA level and pH values revealed from lower NH3:VFA ratio, and improved both in vitro dry matter and organic matter degradabilities. The best impact of the in vitro slow-release urea characteristics of zinc-urea, zeolites-urea, and zeolites-zinc-urea on the ruminal fermentative changes (NH3, VFA, pH, DMD, OMD) was well attributed to the diets contained 6% molasses.

Abstract

Yeast and curcumin of C. xanthorrhiza Roxb could be added into concentrate containingpolyunsaturated fatty acid (PUFA) to improve milk fatty acid quality of dairy goat. There were fivetreatments (PD0: PUFA- diet with no additive; PDA: PUFA- diet with 3 Asifit tablets; PDY: PUFA- dietwith 5 g yeast; PDC: PUFA- diet with 20 g curcuma powder; and PDM: PUFA- diet with a mixture of 5g yeast and 20 g curcuma powder) applied onto 20 dairy goats during late lactation (4.6 ± 0.55 monthsof lactation). The treatments were allocated according to a completely completely randomized blockdesign. Results demonstrated that diet containing PUFA supplemented with 5 g yeast and 20 g curcumawere high in total fatty acid, medium chain fatty acid (MCFA), and long chain fatty acid (LCFA). Milkof goats with this treatment showed high in mono unsaturated fatty acid (MUFA) and MUFA; while itwas low in short chain fatty acid (SCFA), n6/n3 ratio, and atherogenicity index. These qualities wereoptimally considered good in terms of healthier product. Therefore, the PUFA- diet with 5 g yeast and20 g curcuma was a reasonable choice to be applied for dairy goat.

Abstract

Twelve growing female goats (Anglo-Nubian) were assigned to a multiple latin square designexperiment to evaluate the effectiveness of additions of nitrogen (N) supplements to a high isocaloricenergy ration on N utilization. In this experiment, microbial synthesis and N balance were assessed. Thedaily rations were either unsupplemented barley meal (BM), or BM supplemented with one of threenitrogen sources. All rations were isocaloric (3.0 Mcal ME/kg DM) and the N supplements weresoybean meal (BSBM), cottonseed meal (BCSM) or urea (BU) to provide 2.9% N in the concentratecomponent. The unsupplemented BM contained 1.7% N. The addition of N supplements to the rationenhanced N utilization in dairy goats. The organic matter (OM) intake, N intake, N balance, andmicrobial N synthesis for BM, BSBM, BCSM and BU were 660.5 g, 721.9 g, 728.1g and 703.5 g; 13.5g, 21.5 g, 20.9 g and 20.7 g; 2.7 g; 7.1 g, 5.4 g, and 5.7 g; and 14.1 g 19.1 g, 19.1 g, and 20.0 g,respectively. It can be concluded that when sufficient dietary energy was available for ruminal microbialactivities, the source of N did not affect N balance, and microbial N synthesis.

Penelitian ini bertujuan untuk mengetahui potensi limbah rajungan sebagai pakan itik petelur.Itik lokal berumur ±10 bulan sebanyak 60 ekor dialokasikan secara acak ke dalam tiga perlakuandengan lima ulangan yang masing-masing berisi 4 ekor menurut rancangan acak lengkap. Pakandiramu menggunakan, dedak padi, jagung, konsentrat, minyak kelapa dan limbah rajungan dalambentuk tepung. Perlakuan pakan terdiri atas: P1 sebagai pakan kontrol terbuat dari jagung, dedakpadi dan konsentrat, P2 = pakan kontrol + 4% tepung limbah rajungan, P3 = pakan kontrol + 8%tepung limbah rajungan. Pakan diberikan sebanyak140 g/ekor/hari selama 6 minggu. Parameteryang diukur yaitu kualitas eksternal dan internal telur. Hasil analisis statistik menunjukkan bahwapemberian limbah rajungan memberikan pengaruh yang lebih baik (P<0,01) terhadap kerabang telurdan warna kuning telur (P<0,05), sedangkan indeks kuning telur mengalami penurunan yangsangat nyata (P<0,01) dengan penambahan limbah rajungan 4% dan 8%. Namun pada bobot telur,indeks putih telur dan Haugh Unit (HU) dan kandungan kolesterol tidak berbeda nyata (P>0,05).Penggunaan limbah rajungan dalam pakan itik bermanfaat dalam menghasilkan telur dengankualitas yang lebih baik.Kata kunci : Limbah rajungan, pakan, itik, kualitas telur

Abstract

The objective of this study was to evaluate the survival of L. plantarumU40 quantified with real-time PCR during in vitro rumen fermentation. The experiment was arranged in a randomized block design with 3 treatments and 4 replications. Treatments were control, rumen fermentation inoculated with L. plantarumU40and L. plantarumU40 + glucose solution. Population of L. plantarum U40 was higher at inoculation treatment. After 8 hours incubation, glucose addition tended to decrease L. plantarum U40 population. Control treatment showed lowest population of L. plantarum U40 along in vitro fermentation compared with other treatment. Inoculation of L. plantarumU40 significantly (p<0.05) increased population of LAB until 12 hours incubation compared with control. Control treatment had highest pH at all incubation time. Glucose addition significantly (P<0.05) decreased final rumen pH (24 hours) (6.30), compared with control treatment (6.85). Inoculation of L. plantarum U40 with glucose addition significantly (P<0.05)increased propionic acid, decreased acetic acid and A/P ratio compared with other treatments. Lactobacillus plantarum U40 without glucose addition did not affect propionic acid production significantly. As conclusion, Lactobacillus plantarum U40 can survive in rumen fluid and changes rumen fermentation when glucose is added as carbon source.
