Abstract

ABSTRACTThis research was designed to evaluate nutrient digestibility, mentioned as Total Digestible Nutrient of diet containing PUFA (polyunsaturated fatty acid) - concentrate supplemented with yeast and Curcuma xanthorrhiza Roxb for dairy goat. Twenty Ettawah crossbred goat in late lactation were allocated into 6 treatments in randomized block design. The treatments were PD0: PUFA-diet with no supplement, PDA: with Asifit, PDY: with 0.5% yeast, PDC: with 1.5% curcuma, and PDM: with 0.5% yeast + 1.5% curcuma. The PUFA-diet contained of 80% PUFA- concentrate as basic diet and 20% Pennisetum purpureum. While the PUFA sources were roasted ground corn and roasted soybean meal, and corn oil. Results showed that intakes of DM, OM, CP, CF, NFE, ADF, and GE were not affected significantly by dietary treatments. However, EE and NDF among treatments were different significantly (P<0.05), whereas Ca and P were different very significantly (P<0.01). High nutrient contents (DM, OM, CP, EE, CF, NDF, and GE) were found in feces of the goat with curcuma diet (PDC), consequently showed the opposite effects by giving the lowest digestibility (P<0.05 or P<0.01) of these nutrients. Total digestible nutrient (TDN) of PDY and PDM were markedly higher (79.89% and 79.37%, respectively) than that in other diets, such as being the lowest was in PDC (69.94%). This suggested that the yeast concentration of 1.8 108cfu/d, given singly or in combination with 1.5% Curcuma could be considered as the right level for improving nutrient digestibility in the late lactation goat in our study.Keywords: curcuma, dairy goat, PUFA-diet, TDN, yeast

Abstract

An experiment was carried out to investigate the effect of combined supplementation of probiotics and catalyst on digestion and rumen characteristic in Priangan sheep. The trial was conducted using 16 heads of young male Priangan sheep with average initial weight of 18 kg in completely randomized design with factorial 2x2 and 4 replication. The first factor was two types of probiotics mixed with catalyst supplement, while the second factor was two levels of supplement percentage of catalyst at 0.5 and 1.0% of concentrate. The type of probiotics applied was probion and probiotics of buffaloes rumen microbes. The feeding level was set at 3% of body weight based on dry matter and consisting of forage (King grass) and concentrate at 50:50 ratio. The results indicated a significantly greater fibre digestion value (NDF) and proportion of acetate molar in the group of sheep fed combination of probiotics of buffaloes rumen microbes and catalyst supplement. It was concluded that the recommendation level of the combined rumen microbe probiotics with catalyst supplement in sheep ration was 0.5%.

Abstract

Bonggol pisang merupakan limbah pertanian yang masih kurang dimanfaatkan, padahal mengandung senyawa prebiotik berupa glukomanan yang berpotensi meningkatkan kualitas daging ayam. Penelitian ini bertujuan untuk mengkaji potensi glukomanan dari bonggol pisang terhadap profil lemak darah dan kadar kolesterol daging ayam broiler. Penelitian dilakukan menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan dan lima ulangan. Perlakuan yang diberikan meliputi: R0 = ransum tanpa tepung maupun ekstrak bonggol pisang, R1 = ransum dengan 0,85% tepung bonggol pisang, R2 = ransum dengan 0,60% ekstrak bonggol pisang, dan R3 = ransum dengan 0,20% glukomanan komersial. Hasil penelitian menunjukkan bahwa penambahan bonggol pisang ke dalam ransum secara signifikan (P<0,05) menurunkan kadar kolesterol daging, namun tidak memberikan pengaruh yang nyata (P>0,05) terhadap profil lemak darah selama masa pemeliharaan. Berdasarkan temuan ini, glukomanan dari bonggol pisang berpotensi menjadi alternatif prebiotik alami yang lebih aman untuk menggantikan penggunaan antibiotik dalam produksi daging ayam yang sehat dan aman dikonsumsi manusia.

Abstract

Penelitian ini bertujuan mengetahui efektivitas amida minyak ikan dalam menurunkan konsentrasi kolesterol dan trigliserida plasma danpengaruhnya terhadap nilai hematologi darah. Tiga puluh lima ekor tikus jantan, galur Sprague Dawley, umur 7 minggu dibagi secara acak ke dalam lima kelompok perlakuan. Kelompok kontrol (A) mendapat ransum semi purified yang mengandung 8% minyak jagung. Kelompok perlakuan masing-masing disuplementasi 4,5% minyak ikan (B), 3% minyak ikan+1,5% amida (C), 1,5% minyak ikan+3% amida (D), dan 4,5% amida (E). Ransum perlakuan diberikan selama 6 minggu. Pada akhir penelitian dilakukan pengambilan sampel darah untuk menganalisis nilai hematologi dan profil lemak plasma. Hasil penelitian menunjukkan bahwa suplementasi amida minyak ikan dapat mempertahankan jumlah eritrosit dan Hb, namun nilai hematokrit mulai menurun pada suplementasi amida 3% (D), dibandingkan suplementasi minyak ikan (B) dansuplementasi amida 1,5% (C). Jumlah leukosit pada kelompok yang mendapat suplementasi 4,5% amida (E) secara nyata (P0,05) lebih tinggi dibandingkan dengan kelompok yang diberi minyak ikan (B). Suplementasi amida minyak ikan tidak berpengaruh terhadap konsentrasi kolesterol total dan HDL plasma, namun pada suplementasi 3% amida mulai meningkatkan konsentrasi trigliserida dan LDL plasma secara nyata (P0,05). Disimpulkan bahwa suplementasi amida sebesar 3% mulai memperlihatkan pengaruh negatif terhadap nilai hematologi dan profil lemak plasma.

Abstract

Cellulolytic bacterial play an important role in the synthesis of microbial protein in the small intestine as high-quality protein. This research aimed to observe the growth patterns of cellulolytic bacterial isolates from the feces of endemic herbivorous animals in Indonesia, and to evaluate the effect of the addition of cellulolytic bacterial isolates on the synthesis of microbial proteins in vitro. The study used a completely randomized design with four treatments and five replications. The treatments included T0 = Concentrate mix 40%: elephant grass 30%: palm leaves 30% (control), T1 = T0 + 105 CFU mL-1 cellulolytic bacterial isolate, T2 = T0 + 106 CFU mL-1 cellulolytic bacterial isolate, and T3 = T0 + 107 CFU mL-1 cellulolytic bacterial isolate. Variables measured were the growth pattern of bacterial isolates, bacterial population at the optimal growth point, and microbial protein synthesis. The results showed growth pattern of cellulolytic bacterial isolates from Muntjac, Deer and Anoa feces have similar pattern, and was different from the growth pattern of bacterial isolates from bison feces. The optimal growth point of cellulolytic bacterial isolates from the feces of Muntjac, Deer, and Anoa at the 8th hour of incubation with bacterial populations of 1.3 x 109 CFU mL-1, 1.7 x 109 CFU mL-1, and 1.4 x 109 CFU mL-1. The growth pattern and optimal point of cellulolytic bacterial isolates from the feces of Bison at the 12th hour after incubation with bacterial populations of 1,1 x 1010 CFU mL-1. The addition of cellulolytic bacterial isolates did not affect microbial protein synthesis.
