Research topic 1.1.1
For all production factors is the
energy input an indicator for
sustainability. The energy input is
considered in the assessment of
husbandry procedures, too. But
previous investigations about the
energy demand in husbandry neglect
interactions with the plant
production.
The
investigations aim is the
development of a method for
calculating energy determination of
the energy demand in livestock
keeping which consider the
interactions with the plant
production. The determination of the
energy demand in livestock keeping
occurs with inclusion of direct and
indirect energy inputs on the
example of dairy farming. Direct
energy is used in form of fuel oil
and electricity (for example in
feeding, milking and manure disposal).
Indirect energy includes the energy
input for manufacturing machines and
technical equipment (i. e.
feeder-mixer wagons and milking
parlours) as well as animal houses
and storage facilities.
The development
of a method for a detailed
description of the energy demand in
husbandry occurs on the example of
dairy farming. With the help of this
method the assessment and the change
of separate procedure sections shall
be conducted.
The following
graph shows the composition of the
cumulative energy demand in
dependence of the different shares
of the procedure sections.
