Indirect Estimation of CH4 from Livestock Feeds through TOCs Evaluation
Thirty-five available feeds were fermented in vitro in order to investigate their soluble total organic carbon (TOCs) and methane (CH4) production rate. A fermentation reactor was designed to capture the CH4 gas emitted and to collect liquor from the reactor during in vitro fermentation. The results showed that CH4 production rate greatly varied among feeds with different ingredients. The lowes...

متن کاملPresent and future use of cereals as feeds for livestock.
World cereal production and utilization The United Nations Food and Agriculture Organization (FAO, 1975) analysed production and consumption of cereals in 1970 and estimated corresponding values for 1980, 1985 and 1990 (Fig. I). In 1970, livestock ate more than 60% of the cereals consumed in the developed countries but less than 1070 of those consumed in the rest of the world. By 1990 these pro...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
