the current experiment was carried out to investigate the possible effects of replacing alfalfa by dried de-oiled savory (satureja khuzistanica; dds) at the levels of 0, 25, 50, 75 and 100 percent in finishing diets of mehraban lambs on kinetics of gas production in vitro. the experimental diets contained 20% alfalfa and 80% of concentrate on dry matter basis. replacing alfalfa by dds had no si...

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

This study was conducted to determine the nutritive value of soybean varieties using in vitro methods and gas production technique.In vitro gas productions and gas production kinetics of soybean variety were determined at 0, 3, 6, 12, 24, 48, 72 and 96 h incubation times. This study revealed that there were variations among five different soybean varieties in terms of chemical...
