Efficiency of energy utilisation and voluntary feed intake in ruminants.
Energy requirements of animals are most readily expressed in terms of net energy (NE), while the energy yield of feed is, at least initially, expressed in terms of metabolisable energy (ME). Energy evaluation systems 'translate' NE requirements into ME requirements (ME systems) or assign NE values to feeds (NE systems). Efficiency of ME utilisation is higher for maintenance than for production ...
متن کاملEnergy use efficiency, GHG emissions, and carbon efficiency of paddy rice production in Iran
The energy efficiency, greenhouse gas (GHG) emissions, and carbon efficiency of paddy rice production were analysed in Sari in the Mazandaran province of Iran during 2011–2012. Data was collected through questionnaires and interviews with paddy producers. The results showed that the net energy gain was 27,932 MJ ha-1 and energy efficiency was 1.83 during production. The results o...
متن کاملNon-Parametric Energy Use Efficiency, Energy Ratio and Specific Energy for Irrigated Wheat Crop Production
In this paper, non parametric Data Envelopment Analysis (DEA) was subjected to the energy data of wheat producers in Punjab state, India, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. The main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...

متن کاملEfficiency of Feed Utilisation by Ruminants
Metabolisable energy content of a feed or its components has been used to assess its feeding value for ruminants. The demonstration that VFA energy could, at times, be used highly inefficiently when included in a roughage diet, led to the suggestion that feeds for ruminants should be evaluated in terms of their net energy. The establishment of calorimetry technology in nutritional research was ...
