Effect of Essential Oils of Various Plants as Microbial Modifier to Alter Corn Silage Fermentation and in vitro Methane Production
The aim of present study was to assess the effects of individual various essential plant oils on chemical composition, aerobic stability and fermentation characteristics of corn silage and in vitro rumen fermentation and methane emission using gas production technique. Whole crop corn was harvested and ensiled in laboratory scale tubes (4±0.25 kg) for 45 days. Treatments consisted of either cor...
متن کاملEffect of essential oils on ruminal fermentation, microbial population and methane emission in vitro
The effect of adding increasing levels (0, 25, 50 and 75 μl/75 ml buffered rumen fluid) of essential oils (EOs) to a basal substrate (50% roughage: 50% concentrate) on ruminal fermentation characteristics was evaluated in vitro by a semi automatic gas production (GP) technique. The EOs used were from Achillea santolina (AS25, AS50, AS75), Artemisia judaica (AJ25, AJ50, AJ75), Schinus terebenthi...
متن کاملEvaluating in vitro dose-response effects of Lavandula officinalis essential oil on rumen fermentation characteristics, methane production and ruminal acidosis
Four in vitro experiments (Exp.) were conducted to evaluate lavender essential oil (LEO) effects at 0 (control), 250 (low dose), 500 (medium dose), 750 and 1000 µL per L(high doses) of incubation medium on rumen gas production kinetics (Exp.1), ruminal digestibility and fermentation (Exp.2), methane production (Exp.3) and rumen acidosis (Exp.4). The asymptote of gas production (A) incr...
متن کاملMethane Production of Different Forages in In vitro Ruminal Fermentation
An in vitro rumen batch culture study was completed to compare effects of common grasses, leguminous shrubs and non-leguminous shrubs used for livestock grazing in Australia and Ghana on CH4 production and fermentation characteristics. Grass species included Andropodon gayanus, Brachiaria ruziziensis and Pennisetum purpureum. Leguminous shrub species included Cajanus cajan, Cratylia argentea, G...
متن کاملUse of exogenous fibrolytic enzymes to enhance in vitro fermentation of alfalfa hay and corn silage.
Two in vitro experiments were performed to identify promising exogenous fibrolytic enzyme products (EFE) and optimum dose rates (DR) for improving the degradation of alfalfa hay and corn silage. The relationship between enzymatic activity and fermentation responses was examined to identify optimum formulations. In experiment 1, 5 EFE containing mainly endoglucanase and xylanase activities, with...
