Rumen is a persistent and specific ecosystem consists of bacteria, protozoa and fungus where feed fermentation takes place in it. Produced Hydrogen in rumen can be used in the synthesis of the volatile fatty acids and the microbial protein and its excess would be eliminated through the production of Methane by methanogenesis. Nutritionists have tried to find ways to decrease loss and energy and...

The sudden death syndrome (SDS) is a relatively new problem in the feedlot industry. With SDS, apparently healthy cattle in late finishing die suddenly with no sign of sickness or lesions indicative of other diseases. Rumen fluid pH, histamine, total lactate, L(+) lactate and volatile fatty acids (VFA) were compared among 19 SDS cattle, two animals with lactic acidosis produced through grain en...

key dissimilarities between thermophilic and mesophilic anaerobic digestion of waste activated sludge (was) were experimentally studied in this research. typical was with total solids (ts) concentrations of 30 and 60 g/l were digested anaerobically in a batch digester at mesophilic and thermophilic temperatures. solids reduction, total cod changes, the production of different volatile fatty aci...

introduction the common isoform of fatty acids in animal and herbal lipids are cis fatty acids, however in some sources such as milk and meat of ruminant, the trans fatty acids are more abundant as compared to the plant lipids. the trans fatty acids are very important because they increase the cardiovascular and heart attack. the heart disorders were increased by enhancing the concentration of ...

The objective of this study was to evaluate the effects of partially replacing dry ground corn with glycerin on ruminal fermentation using a dual-flow continuous culture system. Six fermenters (1,223 ± 21 ml) were used in a replicated 3x3 Latin square arrangement with three periods of 10 d each, with 7 d for diet adaptation and 3 d for sample collections. All diets contained 75% concentrate and...

1. A method of obtaining dialysed samples from the caecum of the conscious rabbit is described. 2. Values for total volatile fatty acid content and for molar proportions of individual volatile fatty acids in dialysate samples were in good agreement with those obtained from caecal material. 3. The volatile fatty acid level in the caecum throughout the day was determined using two groups of anima...

this study was conducted to determine the nutritive value of fresh and ensiled whole and partly stoned olive cake (oc) with or without molasses i.e., 0 and 50 gkg-1 on fresh basis. dry matter (dm), organic matter (om), crude protein (cp), neutral detergent fiber (ndf), acid detergent fiber (adf), lignin (sa), ether extract (ee), water soluble carbohydrates (wsc), and total phenols (tph) of all ...

to estimate the effect of microencapsulated fish oil on blood metabolites, rumen and blood plasma fatty acids concentrations twelve sannan dairy goats with 30 ± 5 days in milk (dim) were allocated to 3 treatments in a 3×2 change over design with 2 periods of 30 days. treatments were: 1) the control (without fish oil), 2) microencapsulated fish oil (2% fish oil capsulated in 6% treated whey prot...

In this project, different nettle plants from north regions of Iran including Tonekabon, Amol and Gorgan were collected. The oil was extracted using soxhlet extraction apparatus and was subjected to series of physical and chemical tests and determinations consisting of refractive index, melting point, smoke point, nonsaponifiable matter, Iodine value, saponification value, peroxide value, totox...

approved ^ x ;^ ■«= 1 «B (Mtj^or professor) The free fatty acids of Cheddar cheese are important components in the over-all flavor and aroma of the cheese. Although the more volatile fatty acids probably contribute most, there is reason to believe that the higher fatty acids may contribute, to some extent, in imparting typical flavor characteristics. Before the advent of gas-liquid chromatograp...
