Red ginger is herb that commonly used as part of traditional medicine due to its essential oil content. Some essential oil have proven as rumen fermentation modifier. Addition of red ginger in ruminant diet was studied using in vitro gas production technique to evaluate its effect on nutrient digestibility. Red ginger meal was added to meet essential oil level in fermentation medium of 0 mg/l as control, 25, 50, 75 and 100 mg/l. The diet consisted of Penisetum hybride, rice bran, wheat pollard in ratio 60:20:20 DM basis. Feed fermentation was incubated for 24 h at 39Â°C. At the end of incubation data of gas production volume was taken, and residual feed were collected for further nutrient analysis to calculate the digestibility of dry matter (DM), organic matter (OM), crude protein (CP) and crude fiber (CF). Variance analysis was used to analysis collected data, followed by DMRT analysis.Â Addition of red ginger increase total volume of gas production at level 50 mg/L and above. DM and OM digestibility did not affected by red ginger addition whereas CP digestibility were significantly decreased start at level 50 mg/l. In contrast, CF digestibility of treatment level of 50 mg/l significantly higher than control. In conclusion, addition of red ginger correspond to level essential oil of 50 to 100 mg/l improve ruminal nutrient fermentation.

In-vitro teknik produksi gas dapat digunakan untuk prediksi kualitas pakan. Pengaruh penambahan molase sebagai sumber karbohidrat mudah terdegradasi pada pakan sumber protein silase red clover dipelajari dengan menggunakan teknik ini. Dari data yang diperoleh menunjukkan terdapat korelasi positif antara total produksi gas dengan nilai kecernaan pakan (r = 0,96). Korelasi positif antara total produksi gas dengan produksi biomasa mikroba (r = 0,96). Penambahan molase sangat nyata meningkatkan nilai kecernaan bahan kering (P<0,01) meningkatkan bahan kering terdegradasi (P<0,01) dan produksi biomasa mikroba (P<0,01), serta meningkatkan efisiensi nitrogen pakan dalam pembentukan biomasa mikroba (P<0,01) seiring dengan peningkatan jumlah suplementasi. Penambahan 0,3 g molase menunjukan hasil yang tertinggi sementara penambahan 0,15 dan 0,225 molase memberikan hasil yang lebih bail dibanding penambahan 0,0625 molase dan red clover tanpa supelementasi. Dari hasil yang diperoleh dapat disimpulkan bahwa in-vitro teknik produksi gas dapat digunakan untuk evaluasi dan pemilihan bahan pakan untuk ternak.

This study were aimed to determine the dry matter and organic matter intake, nutrients digestibility, body weight gain and physiological status of male Bligon goats treated with feed restriction. Six Bligon goats average age of 12 months and an average body weight of 23.6 kg were fed 40% of peanut raughages (rendeng) and 60% concentrate. Goats were divided into two (2) treatment groups. Control goat treatment were fed diets based on dry matter (DM) requirements 3.5% of body weight, and feed restriction goat treatment were fed diets with 50% reduction of DM requirement. Feed restriction was conducted for 35 days. The variables measured were dry matter (DM) and organic matter (OM) intake, total digestibility nutrient (TDN) intake, body weigh gain, dry matter (DM) and organic matter (OM) digestibility, rectal temperature, respiration frequency, and heart rate. Data were analyzed by independent samples T-test. The results showed that the feed restriction significantly decreasedconsumption of DM (676.07 ± 14.76 into 372.30 ± 53.08) and OM (639.38 ± 15.89 into 349.88 ± 49.35), consumption of TDN (461.60 ± 10.23 into 253.99 ± 36.17), DM digestibility (74.39 ± 1.60 into 71.27 ± 0.89) and OM digestibility (79.42 ± 1.54 into 76.34 ± 0.24), but had no significant effect on body temperature, respiration frequency and heart rate (pulsus) of male Bligon goat. Value of ADG was 55.24 g/day (P0) then increased to 131.43 g/day when the feed was filled back. A feed restriction up to 50% decreased goat production performance, but did not interfere with the health status of livestock (can be indicated from physiological status of goat still in the normal range).

This research was done to study the effect of four essential oils (EOs), as feed additives, on ruminal nutrient digestibility in order to find out candidate of rumen modifier. Those four EOs were destilated from Foeniculum vulgare (Mill), Pinus merkusii (Jungh. & de Vriese), Cymbopogon nardus (L.) Rendle and Melaleuca leucadendra (L.). Their effect on dry matter (DM), organic matter (OM), crude protein (CP) and crude fiber (CF) digestibility were studied using in vitro rumen fermentation technique according to Theodorou method. Data were statistically analysed using analysis of variance factorial 4x5 design. Feed for fermentation substrate consist of Pennisetum purpureum, rice bran and wheat pollard. Essential oil individually was added and mix with substrate to meet the final concentration in fermentation media of 0, 100, 200, 400 and 800 mg/l. P. merkusii, C. nardus and M. leucadendra EOs reduced DM, OM, and CF digestibilities. The decreasing were in line with the increasing of EOs doses. Therefore F. vulgare only reduced CF digestibility. The value of DM, OM and CP digestibilities in fermentation with F. vulgare did not differ from control. CP digestibility differed among EO treatments. In F. vulgare, and P. merkusii, treatments, CP digestibility did not differ from control, whereas overall CP digestibility in C. nardus tended to be higher than control and CP digestibility in M. leucadendra was significantly higher. All EOs addition reduced CF digestibility at all level. CF digestibility in fermentation added 800 mg/l of M. leucadendra EO was slumped to only 14.29% of control. Among four EOs M. leucadendra is the most potent on interrupt rumen feed fermentation whereas P. merkusii and C. nardus in moderate ways and F. vulgare in delicate manner.

Essential Oil (EO), as feed additive, is known to increase the feed efficiency and reduce the methane production among ruminants. This research was done to study the effect of java cardamom (Amomum compactum Soland ex Maton) essential oil as feed additive on ruminal feed fermentation. The in vitro gas production technique was used in this research to determine the effect of cardamom on nutrient fermentation in the rumen. Cardamom meal was added into the feed sample to get end concentration of EO in the fermentation medium as much as 0, 25, 50, 75 and 100 mg/l. The substrate consisted of Pennisetum purpureum, rice bran and wheat pollard. The addition of cardamom did not significantly affect the digestibilityof dry matterÂ Â except at 100 mg/l in which it decreased. Protein digestibility decreased when the diet was added with cardamom, whereas organic matter and crude fiber digestibility increased up to 13.5% and 24% level of EO100mg/l respectively. Â The production of volatile fatty acid (acetate, propionate, butyrate), pH and microbial protein synthesis except the ammonia concentration, were not affected by cardamom addition. Similarly, the methane production and protozoa population did not significantly change. The utilization of java cardamom as feed additive positively affected the ruminal feed fermentation by increasing the organic matter and crude fiber digestibility and reducing the protein digestibility.
