Background and objectives: Regular preparation of good quality forage and proper diet leads to cost-effective production of milk and meat. In Iran, insufficient supply and insufficient access to forage, as well as unbalanced consumption diets are the main limitations that negatively affect the ability to produce buffalo and therefore lead to uneconomical breeding of this animal. To overcome the...
in this experiment, fermentation parameters of a tmr ration determined with different levels of phosalone as an organophosphate pesticide (0, 100, 250, 500, 750 and 1000 ppm) and bentonite (0, 1 and 2 %dm of tmr) using in vitro batch culture and gas production techniques. the results from gas production showed that cumulative gas production for 96h after incubation significantly decreased with ...
The fermentation of the neutral detergent-soluble (NDS) fraction of two legumes (clover, alfalfa) and two grasses (timothy, guinea grass) was measured using a curve subtraction technique with in vitro gas production data from the whole forage and the isolated neutral detergent-extracted fiber. The NDF disappearance and VFA production also were measured. There were no significant differences bet...
Introduction: Unit risk management is a critical component of gas refining management, as risks that are not well-managed may lead to trip production failures. The present study aimed to provide a structural model for investigating the role and effect of different variables on stopping the gas production process in the gas refinery. Material and Methods: This study was a retrospective cross-se...
abstract the aim of this study was to evaluate the effect of ajowan essential oils (aeo) on rumen fermentation using in vitro gas production. therefore, different doses of aeo (i.e., 0, 150, 300, 450 or 600 ppm) were added to the syringes of the gas production. a typical diet of growing lambs was used as fermentation substrate. at the first step, the gas production syringes were in...
the aim this research is the diagnosis of production chains in oil’s regions of iran. for this reason, by using, input-output table for oil’s regions of iran,linkages and production chains are identified. the results of research indicate that although oil and natural gas sectors contain 50 percent of region’s output, but it is not a leading sector. in contrast, manufacturing of species of machi...
The chemical composition and in vitro gas production of some leguminous browse species were evaluated. Crude protein (CP) content was highest (P
