Ruminal Volatile Fatty Acid Production in Relation to Animal Production from Grass.
T h e studies of Sir Joseph Barcroft and his colleagues (Phillipson & McAnalIy, 1942; Barcroft, McAnally & Phillipson, 1944) at Cambridge in the early 1940s established that the volatile fatty acids (VFAs) produced during the fermentation of foodstuffs within the rumen of sheep and cattle are absorbed through the rumen wall and metabolized by the tissues. I t has since been shown (see Annison &...
متن کاملThe Potential for Biogas Production from Grass
Grass is generally considered as one of the major agricultural products and covers over 90% of Irish agricultural land. While useful as an animal feedstock it can also be used for energy production. Here batch mesophilic anaerobic digestion of grass silage was studied. The methane concentration in the biogas clearly showed that grass silage has a high affinity to produce a high quality methane ...
متن کاملFuel Pellet Production from Reed Canary Grass
This thesis focuses on two main areas: methods for assessing regional supply potentials of reed canary grass (Phalaris arundinacea L.) (RCG); and process technology for the production of high-quality RCG pellets. Partial equilibrium modelling, incorporating a break-even price approach, was used to examine supply potentials for RCG in Västerbotten County, northern Sweden. A remote sensing method...
متن کاملMilk Production from a Tropical Legume-grass Pasture
One member of each of three pairs of monozygous twin dairy cows was fed freshly cut Glycine javanica and kikuyu-grass pasture ad libitum while the co-twins were fed lucerne hay ad libitum and a concentrate mixture. The mean daily digestible organic matter and digestible crude protein intakes for the cows fed pasture were 7.0 kg and 1.35 kg, and for the cows fed hay and concentrates were 10.2 kg...
متن کاملElectricity-assisted production of caproic acid from grass
BACKGROUND Medium chain carboxylic acids, such as caproic acid, are conventionally produced from food materials. Caproic acid can be produced through fermentation by the reverse β-oxidation of lactic acid, generated from low value lignocellulosic biomass. In situ extraction of caproic acid can be achieved by membrane electrolysis coupled to the fermentation process, allowing recovery by phase s...
