The purpose of this study was to examine the effects fermentation parameters on addition clove oil oat straw, alfalfa hay, and maize silage at a 3% dry matter basis. In vitro gas production, methane production (CH4), metabolic energy (ME), net lactation (NEL), organic digestion (OMD) were all influenced by (P

In order to enhance knowledge of the nutritive value of ostrich feeds, the in vitro gas production technique was used. Five feeds (corn silage, CS; alfalfa hay, AH; barley, BG; soybean meal, SM; beet pulp, BP) were weighed (~ 1g) in quadruplicate in 120 ml serum flasks and incubated at 39 °C with 75 ml of anaerobic medium and 4 ml of reducing solution. A pool of caecal contents obtained at slau...

the effect of inclusion of garlic essential oil (eo) at 33, 66 and 100 μg ml-1, raw garlic (gar) at 5, 10 and 15 mg ml-1 and monensin (mon) at 7.5 μg ml-1 of incubation medium on organic matter digestibility (omd) was studied with in vitro gas production, ankom daisyii and conventional in vitro (ivomd) methods. the material was incubated with sheep ruminal fluid and the experimental design was ...

background: landfills are the most important producers of methane as human source. so, prediction of landfill gas generation is by far the most important concern of scientists, decision makers, and landfill owners as well as health authorities. almost all the currently used models are based on monod equation first order decay rate which is experimental while the main purpose of this research is...

grafting of cucurbitaceae species to some rootstocks seems to be especially beneficial for the nitrogen nutrition of these plants. moreover, melons (cucumis melo l.) have been considered among those plants that could benefit from the addition of silicon (si) in the nutrient solution (ns). thus, two experiments were carried out in the following order: (i) it was investigated how grafting affects...

in order to estimate the nutrient value of three dominant range species; festucaovina, trifolium montanum and alopecurus textilis via proximate analyses and gas productiontechnique, samples were collected in three stages during grazing period from 26th may to 1thseptember in six areas of sabalan mountain in north west of iran. results showed thattrifolium montanum as a legume had higher values ...

The purpose of this study was to assess the in vitro antimicrobial activity of alkaloid-enriched extracts from Prosopis juliflora (Fabaceae) pods in order to evaluate them as feed additives for ruminants. As only the basic chloroformic extract (BCE), whose main constituents were juliprosopine (juliflorine), prosoflorine and juliprosine, showed Gram-positive antibacterial activity against Microc...

the present study was carried out to determine the nutritive value of white varieties of grape pomace (gp) and raisin vitis leaves (rvl), using nylon bags and gas production techniques. tow fistulated whether with average body weight of 45±2 kg were used. the amount of gas produced was measured at 2, 4, 6, 8, 12, 16, 24, 36, 48 and 72 h times and degradation was measured using nylon bags up to ...

A three-dimensional computational fluid dynamics model of a proton exchange membrane fuel cell (PEMFC) with both gas distribution flow channels and Membrane Electrode Assembly (MEA) is developed. A set of conservation equation is numerically solved by developing a CFD code based on the finite volume technique and SIMPLE algorithm. In this research, some parameters like oxygen consumption, water...
