Anaerobic co-digestion of cocoa husk with digested swine manure: evaluation of biodegradation efficiency in methane productivity CIGR Journal
Darwin, Darwin.
The purpose of this study was to investigate the potential of methane production from anaerobic co-digestion of coco husk with digested swine manure.  The experiment was set up in the batch system.  Inoculum utilized in this experiment was derived from semi-continuous reactor run at steady state condition, with 25 days of hydraulic retention time and mesophilic condition.  The temperature applied in this experiment was maintained under mesophilic condition, which was 35oC.  The highest methane productivity generated from anaerobic co-digestion of cocoa husks (CH) with digested swine manure was 345.8 ± 7.82 mL/day, which was higher compared with the anaerobic digestion of digested swine manure alone (286.97 ± 16.8 mL/day).  CH reactors had less methane...

Abstract: The objective of this work was to evaluate three tropical forage species for their in vitro methane (CH4) production and organic matter degradability, in order to determine the relationships between forage grass nutritive quality and CH4 production. Guinea grass (Megathyrsus maximus), palisade grass (Urochloa brizantha), and signal grass (Urochloa decumbens) were evaluated. Palisade grass showed the highest organic matter, neutral detergent fiber, acid detergent fiber, lignin, and lower-crude protein content. Signal grass had the highest values for hemicellulose and neutral detergent fiber-nitrogen, and the lowest-cellulose content. Guinea grass and signal grass showed a higher-total gas production than palisade grass. Besides, Guinea grass...

การปลดปล่อยแก๊สมีเทนในโคพื้นเมืองไทยที่ได้รับอาหารหยาบคุณภาพต่ำ Thai Agricultural
Kanokwan Kongphitee; Kritapon Sommart.
Objective of this study was to estimate methane production in Thai native cattle fed dried Ruzi grass or rice straw based diets. Twelve Thai native bull (body weight 342.25±30.46 kg.) were used in this experiment. Dietary treatments were applied in a randomized complete block design (RCBD) consisted of ad libitum mixed 70%of concentrate with 30% of dried Ruzi grass based diet (T1), ad libitum 70% of concentrate with 30% of rice straw based diet (T2) and 70% of concentrate with 30% of rice straw based diet stair step feeding (T3). The nutrient intake and methane production were not significant different (P>0.05) between animals fed dried Ruzi grass and rice straw based diets. Dry matter and organic matter intake (on the basis of % BW and g/kg W0.75/d) in...
