Det er i dag underskot på storfekjøtt i Noreg, og det er politisk vilje til å satse på auka
produksjon i åra framover.
Denne oppgåva går ut på å prosjektera nytt fjøs for ammekyr på garden Heimtun med særleg
fokus på dyrevelferd, innandørsmekanisering, bygningskonstruksjon og byggekostnad/
økonomi.
Det har blitt gjennomført gardsbesøk og samtalar med folk i næringa, og på bakgrunn av dette
har det blitt teikna tre forskjellige planløysingar som har blitt sett opp mot kvarandre i ein
tabell og vurdert med poeng utifrå gitte nøkkelpunkt.
Fjøset som blei valt er planlagt bygd i tre, uisolert med naturleg ventilasjon. Resultatet gir god
dyrevelferd iform av inneklima, godt utforma liggjebås og at alle har plass ved fôrbrettet.
Utfôring blir gjort med minilastar, og gjødsla vil vere spaltegolv og kanalomrøring med
transport til eksisterande lager.
Oppgåva er ein fin plattform for vegen vidare mot nytt fjøs på garden Heimtun. Kostnaden
ved det prosjekterte bygget er høg, og det må jobbast meir med løysingar som kan få ned
prisen, herunder ei vurdering av optimal storleik på besetninga. Neste steg kan vere å utarbeida
ein driftsplan som vil vere med på å gi betre svar når det kjem til lønnsemda ved nybygging.
Med utgangspunkt i valt problemstilling tykkjer eg at det har blitt prosjektert eit lettdrive fjøs
som ivaretek god dyrevelferd og moglegheiter for å bidra til målet mot auka produksjon av
storfekjøtt på norske beiteressursar. Norway’s own production of beef is less than the actual domestic market demand, and there
is an increasing effort and political willingness from the government to increase the domestic
beef production in the coming years utilizing uncultivated pasture locally available.
This report presents the results from the planning of a new building and production facilities
for beef cattle on the farm Heimtun, located at the west coast of Norway. Three key premises
where defined, namely high focus on animal welfare, indoor layout and facilities, civil
engineering and construction, and overall cost picture. Review of national rules and
regulations related to breeding of beef cattle, including recently published articles from
research institutions, as well as visiting cattle farms seeking best practices and operational
experiences from breeding of beef cattle in different parts of Norway, has been performed to
establish premises and best practices for developing the solutions. Three concepts where
outlined in the screening phase and compared based on predefined screening criteria. The
concept having the highest score was then selected for further development.
The chosen building concept to be presented here uses primarily wood as construction
material, is based on natural ventilation and without any thermal insulation material in the
walls and roof. The layout and outfitting of the building is supposed to provide good animal
welfare conditions for the cattle, cows and calves, in an environment of fresh air, comfortable
and designated recreation/resting area, and easily access to the spacy feeding area. A mini -
loader or a tractor will be used for the distribution of forages and silage in the feeding area.
Slatted floor drains the manure from the cows and calves to a channel system underneath the
floor where the manure is collected and temporarily stored. The channel system also includes
a pump that circulate the manure at regular intervals prior to being transported to permanent
storage location.
The outcome of the work is considered being a good start for further maturing and decision
process regarding new building for beef cattle on the Heimtun farm. There is however, a
significant cost level challenge being too high, and further work should include cost cutting
exercises in general and a process defining optimum number of cattle and the sizing of the
building and facilities. An overall business plan for the farm should be developed addressing
the different production alternatives including thorough economic and risk analysis. These analyses should provide input for a decision process of how to proceed regarding new building
for beef cattle on the farm Heimtun.
Given the chosen topic, my closing remarks would be that the proposed solution for a new
beef cattle building on the farm Heimtun is an efficient, modern and forward looking concept
focusing on high level of animal welfare. That should be the correct starting point for the
realization of the expressed ambition – namely to increase the domestic beef production taking
advantage of the locally available pasture resources.
