Investigation of Total Energy Requirement in Cattle Fodder Production

摘要

The report gives results of the determination of total energy requirements per unit of cattle fodders produced by two milk production farms. The specific total energy requirements (STER) and specific number of man-hours (SNMH) were computed relative to cultivated areas, fattening feed units, and wheight of different fodder as follows: Meadow and pasture grass, silage, rape, kale, turnipcabbage and straw. The values of STER and SNMH were used as a base to find the total energy requirements of produced milk. The structure of fuel and energy consumption and of man-hours in various fodder technologies in order to analyse them, rationalize these consumptions and reduce the labour costs were determined. From a questionaire completed by farmers and investigators the obtained information was evaluated by aid of a computer program using the language BASIC. The necessary specific values of total energy in fuels, electricity, materials, machines, equipment and production buildings were obtained from the references and previous research. Results from detailed machinery studies were also used. The productivity, total energy requirement and labour input for the fodders were calculated. The presented computation method of total energy requirement seems to be good for analyzing cattle fodder STER. It would also be possible to make a simulation computing of STER based on the presented method. 6 appendices showing the questionnaire investigation, general data of computations, values of constant indices, describing the program of computation, total energy requirements for the fodders and calculation of some indices are included. 28 tables.
