Accumulation of environmentally hazardous agricultural waste, in particular cow manure without the proper treatment, creates an ecological threat to environment. During energy crisis, search for alternative pathways obtain is also one most urgent issues today. Cow promising as a substrate anaerobic fermentation with production valuable carrier — methane. Fermentation sole not spread. It takes p...

Four rumen fistulated swamp buffaloes were randomly assigned according to a 4×4 Latin square design to investigate the effects of Eucalyptus (E. Camaldulensis) leaf meal (ELM) supplementation as a rumen enhancer on feed intake and rumen fermentation characteristics. The dietary treatments were as follows: T1 = 0 g ELM/hd/d; T2 = 40 g ELM/hd/d; T3 = 80 g ELM/hd/d; T4 = 120 g ELM/hd/d, respective...

The effect of substituting native grass with jengkol (Archidendron jiringa) by-product on fermentation characteristics, rumen microbial profile, methane production, and hydrogen balance using in vitro method was investigated. Seven treatments (different composition of native grass, jengkol peel, jengkol leaves, and concentrate) with five replications in a block randomized desi...

Introduction According to the National Greenhouse Gas Inventory (NGGI 2007) the agricultural sector contributes around 16% of national greenhouse gas emissions (Figure 1). The main greenhouse gases emitted from agriculture include methane lost during rumen digestion (enteric) and nitrous oxide lost from nitrogen fertilisers, animal excreta and soils (Figure 1). Agriculture accounts for 60% and ...

Increasing atmospheric concentrations of methane have led scientists to examine its sources of origin. Ruminant livestock can produce 250 to 500 L of methane per day. This level of production results in estimates of the contribution by cattle to global warming that may occur in the next 50 to 100 yr to be a little less than 2%. Many factors influence methane emissions from cattle and include th...

Two trials were conducted to investigate the effects of disodium fumarate (DSF; 0.00, 8.00, 10.00 and 12.00 mM) and thyme essential oil (TEO; 0.00, 100.00, 200.00, 300.00 and 400.00 µL L-1) solely and simultaneously (10.00 mM DSF along with 100.00, 200.00, 300.00 and 400 µL L-1 TEO) on in vitro ruminal fermentation of a 50:50 alfalfa hay to concentrate diet. The D...
