Abstract

Farmers in Indonesia utilize a substantial amount of rice straw to provide feed for their livestock but restricted in terms of its low nutritional value. This study was conducted with objective to evaluate the quality of rice straw silage with addition of sacha inchi (Plukenetia volubilis L.) meal and sambung nyawa (Gynura procumbens) leaves based on physical, chemical, and microbiological properties. The study employed a completely randomized design with 9 treatments (P0: 100% rice straw, P1: 90% rice straw + 10% sacha inchi meal, P2: 85% rice straw + 15% sacha inchi meal, P3: 80% rice straw + 20% sacha inchi meal, P4: 75% rice straw + 25% sacha inchi meal, P5: P1+10% sambung nyawa leaves, P6: P2+10% sambung nyawa leaves, P7: P3+10% sambung nyawa leaves, P8: P4+10% sambung nyawa leaves) and 5 replications, incorporating the addition of sambung nyawa leaves. The variables examined include the physical quality i.e. colour, flavour, texture, and presence of mold; chemical quality i.e. pH, crude protein (CP), and crude fibre (CF); and microbiological quality i.e. lactic acid bacteria (LAB), yeasts, aerobic bacteria, and pathogenic bacteria. The results of the physical quality test indicated that the addition of sacha inchi meal and sambung nyawa leaves resulted no significant difference. On the other hand, the chemical quality showed that the addition of sacha inchi meal and sambung nyawa leaves have enhanced the rice straw silage nutritional content (p<0.05) particularly CP content by about 4 fold. The microbiological tests showed that the addition of sacha inchi meal and sambung nyawa leaves had an impact on the preservation of silage by inhibiting the growth of pathogenic microorganisms. It is concluded that the quality of rice straw silage has improved by the addition of 10-25% sacha inchi meal and 10% sambung nyawa leaves

Abstract

Objective: This study aimed to select Lactiplantibacillus plantarum strains suitable for inoculant of rice straw fermentation and to evaluate its fermentation characteristics.Methods: The experiment was conducted at the Feed Bioprocess Laboratory, Research Center for Applied Zoology, National Research and Innovation Agency (BRIN). This experiment was designed using a 3×4 factorial arrangement in a completely randomized design (CRD). The first factor was inoculant (1%), and the second was incubation time (7, 14, 28, and 58 days). The first stage was selection of 9 strains of L.  plantarum, based on the ability to lowering the pH and produce lactic acid. The second stage was observing the growth curve of the selected strains of L. plantarum as inoculant for rice straw fermentation. The third stage was monitoring of the rice straw fermentation characteristics, including pH values, concentration of lactic acid, water-soluble carbohydrates (WSC) and NH3-N, also dry matter, ash and crude protein. Data were analyzed based on analysis of variance, and if there was a significant effect, the data were further analyzed with Duncan’s Multiple Range Test.Results: The selected strains L. plantarum Ca098 and L. plantarum 1A-2 showed significant interaction result (p<0.05) compared with treating inoculant and ensiling days. The fermentation time influenced (p<0.05) the quality of rice straw fermentation including pH, concentration of lactic acid, WSC, NH3-N, and crude protein.Conclusions: L. plantarum Ca098 showed the best rice straw fermentation characteristics, with fleigh value of 163.86±5.97 at 58 days of fermentation. L. plantarum Ca098 showed the highest lactic acid, the lowest pH and improve crude protein content.

Abstract

The aims of this experiment were to  identify and characterize of sediment product from cattle rumen liquor as a source of amino acids, minerals and vitamins. The sediment were obtained as pellets upon centrifugation of rumen liquor at 10,000 g for 10 minutes for collection of supernatant. The sediment were evaluated for amino acids, minerals and vitamins composition and chararacterized for the pH,  solubility of dry matter, specific density, bulk and compacted bulk densities and angle of response. Result of the experiment showed that sediment contained higher minerals:  Na, K and Fe compared with the commercial premix, but lower in B-vitamins and amino acids. The composition of mineral Na, K, and Fe from rumen liquor of local cattle was 13.47%, 7.73 % and 14.52 %,  while Na, K, and Fe from  rumen liquor of  imported cattle was 18.40%, 10.25%, and 14.52% respectively. The sediment had pH range from 10.01-10.03, the dry matter solubility  was 35.5% up to 39.1%. The sediment from imported cattle had higher specific density, bulk and compacted bulk densities and angle of response than that of local cattle. It is concluded that sediment from cattle rumen liquor contained high Na, K and Fe, low amino acids and B-vitamin, high pH and low solubility.
