Effect of Moisture Content and Different Levels of Additives on Chemical Composition and in vitro Dry Matter Digestibility of Rice Straw

The chemical composition and in vitro dry matter digestibility of 45 samples of different species of lichen are reported. Mean content (g/100 g dry matter) of the main nutrients was: crude protein 4.2, crude fat 3.2, crude fibre 16.6, ash 1.9, Ca 0.15, P 0.09, Mg 0.05, K 0.13, Na 0.035, S 0.07. The content of microminerals (mg/kg dry matter) was: Cu 2.5, Mo 0.11, Zn 27.2, Se 0.12, Fe 898, Mn 154. The mean in vitro dry matter digestibility was 35%. However, the in vitro method do underestimate the dry matter digestibility of lichens. Stereocaulon spp. showed higher levels of crude protein, P, S, Cu and Mo than Cetraria spp. and Cladonia spp. Cetraria nivalis showed higher digestibility and contained more NFE, ash, Ca, Mg, but less crude fibre than Cladonia stellaris. Lichens contained less amounts of most nutrients compared with grasses (Fig. 1), exept for crude fat, NFE, Se and Fe.Kjemisk innhald og in vitro fordøyelsesgrad av lav.Abstract in Norwegian / Samandrag: Kjemisk innhald og in vitro fordøyelsesgrad av tørrstoffet er bestemt i 45 prøver av beitelav frå to stader i Sør-Noreg. Middel innhald (g/100g tørrstoff) av følgjande næringsstoff var: protein 4.2, feitt 3.2, trevlar 16.6, oske 1.9, kalsium 0.15, fosfor 0.09, magnesium 0.05, kalium 0.13, natrium 0.035, svovel 0.07. Innhaldet (mg/kg tørrstoff) av mikronæringsstoffa var: kopar 2.5, molybden 0.11, sink 27.2, selen 0.12, jern 898 og mangan 154. Den midlare fordøyelsesgraden av tørrstoffet i lav-prøvene var 35%, men in vitro fordøyelsesanalyser undervurderer fordøyelsesgraden av lav. Det var ein stor variasjon mellom dei ulike lavartane for dei fleste næringsstoffa og fordøyelsesgraden. Stereocaulon spp. inneheldt meir protein, fosfor, svovel, kopar og molybden enn Cetraria spp. og Cladonia spp. Gulskinn hadde høgare fordøyelsesgrad, og innehaldet av NFE, oske, kalsium og magnesium var høgre enn i kvitkrull, medan trevleinnhaldet var størst i kvitkrull. Lav inneheldt mindre av dei fleste næringsstoffa samanlikna med gras, unnateke feitt, NFE, selen og jern.Jäkälien kemiallinen sisältö ja in vitro sulatuksen aste.Abstract in Finnish / Yhteenveto: Kuiva-aineen kemiallinen sisalto ja in vitro sulatusaste on mååråtty 45:ssa kokeessa tårkeistå laidunjåkålistå kahdella paikkakunnalla Etelå — Norjassa. Keskimååråinen sisalto (g/100 g kuiva-ainetta) seuraavissa ravintoaineissa oli: valkuaisainetta 4.2, rasvaa 3.2, kuituja 16.6, tuhkaa 1.9, kalsiumia 0.15, fosforia 0.09, magnesiumia 0.05, kaliumia 0.13, natriumia 0.035, rikkia 0.07. Hivenainepitoisuus (mg/kg kuiva-ainesta) oli: kuparia 2.5, molybdeenia 0.11, sinkkia 27.2, seleeniå 0.12, rautaa 898 ja mangaania 154. Kuiva-aineiden keskimååråinen sulatusaste jåkålåkokeissa oli 35%. Eri jåkålåajien vålillå oli suuri vaihtelu eisimmissa ravintoaineissa ja sulatusasteessa. Stereocaulon spp. sisålsi enemmån valkuaisainetta, fosforia, rikkiå kuparia ja typettomien uuteaineiden, molybdeeniå kuin Cetraria spp. ja Cladonia spp. Lapalumijåkålållå oli korkeampi sulatusaste, ja tuhkan, kalsiumin ja magnesiumin sisålto oli korkeampi kuin Cladonia alpestris-jäkälässä, mutta kuitusisålto oli korkein Cladonia alpestris-jäkälässä. Jåkålå sisålsi våhemmån useimmista ravintoaineista ruohoon verrattuna lukuunottamatta rasvaa, typettomiå uuteaineita, seleeniå ja rautaa.

The effect of molasses on ammoniated straw by using urea on dry and organic matter digestibility as in vitroABSTRACT. Aimed of this research was to find out the optimal level of molasses addition to improve quality, dry matter and organic matter digestibility of rice straw ammonization process. Materials used were rumen fluid of fistula cattle, grind of rice straw, water, urea and molasses. Research designed used Completely Randomized Design (CRD). As treatments were R0: rice straw 1000 g dry matter + 500 g water + 50 g urea + 0 percent of molasses, R1: R0 + 15 percent of molasses, R2: R0 + 30 percent of molasses. Urea and molasses dissolved in water and then entered into pollybag. All pollybag observe and let for 15 days, each treatment replicated 6 times. Variable measured were dry matter digestibility and organic matter digestibility. Research result showed that ammonization product of NH3, Acidity Level and crude fiber having decreased while crude protein content increased. Variance analysis indicated that treatments had significant effect (P0.05) on dry matter and organic matter digestibility. Orthogonal polynomial test indicated that level of molasses increase (P0.05) of dry matter and organic matter digestibility linearly. It can be concluded that addition up to 30 percent in ammoniating of rice straw using urea can improve quality of ammonization and increasing dry matter and organic matter digestibility.

Dry Matter Digestibility

The influence of the ratio of fermented rice straw, rice bran and cassava solid waste upon the In vitro digestibility and rumen fermentation productABSTRACT. Chemical and physical treatments have been attempted to improve the utilization of agro industrial wastes, but the result is not efficient and caused pollution. Besides, biological treatments using the microbes have been used to improve the nutritive value and utilization of agro industrial wastes. The current experiment was conducted to find out the optimal ratio of fermented rice straw, fermented rice bran and fermented tapioca waste. There were five kinds of ratio of fermented rice straw, fermented rice bran and fermented tapioca waste, namely: K1 (70% fermented rice straw + 15% fermented rice bran + fermented tapioca waste), K2 (60% fermented rice straw + 20% fermented rice bran + 20% fermented tapioca waste), K3 (50% fermented rice straw + 25% fermented rice bran + 25% fermented tapioca waste), K4 (40% fermented rice straw + 30% fermented rice bran + 30% fermented tapioca waste) and K5 (30% fermented rice straw + 35% fermented rice bran + 35% fermented tapioca waste) An in vitro technique, using completely Randomize Block Design was applied and each treatment was repeated four times. Variables measured were Dry matter and Organic matter digestibility and rumen fermentation products (volatile fatty acid and N-NH3 concentration). The dry matter digestibility of K1, K2, K3, k4 and K5 was 29.39, 31.27, 32.33, 33.71 and 34.82%, respectively. The organic matter digestibility of K1, K2, K3, K4 and 5 was 30.82, 31.27, 32.73, 34.94, and 34.92, respectively. Volatile fatty acid concentrations of K1, K2, K3, K4 and K5 were 95.19, 91.77, 87.21, 104.31, 106.59 mM/l, respectively. N-NH3 concentrations of K1, K2, K3, K4 and K5 were 0.97, 0.93, 0.93, 1.00, 1.04 mM/l, respectively. Significant difference (P0.01) was only found in dry matter digestibility among treatments, while others variables were not significantly different among treatments. It was indicated that the optimal ratio was K4.

Organic Matter Digestibility

This research aims to improve the digestibility and nutritional value of rice straw as a ruminant animal feed and determine the effect of long soaking in sea water of rice straw on digestibility in vitro dry matter and organic matter. The used materials in this study are a bales machine, weighing scales, rapiah rope, poly bags, rice straw varieties Ciliwung obtained from rice fields in Bantimurung, sea water with 2.71% saline, as well as tools and chemicals for analysis of in vitro dry matter and organic matter digestibility with pepsin, calculus method. This study is done based on Randomized Complete Design (RCD) with 5 treatments and 4 replications. Variance based on the long soaking treatment gives the nature of the response curve linear on the digestibility of dry matter and also to organic matter digestibility. The magnitude of the correlation length relationship soaking rice straw and with sea water for in vitro dry matter and organic matter digestibility that is 96.5% and 96.8% respectively. Based on the results of research and discussion can be concluded that rice straw is soaked with sea water 3-12 days producing dry matter digestibility and organic matter are higher than the rice straw that is not soaked with sea water. Soaking of the sea water for 3-12 days increase the digestibility of dry matter and organic matter.
