Niðurstaða
Fóðurgangar með færanlegum
ffamhliðum er áhugaverð lausn þar
sem fóðrað er að stómm hlua með
einsleitu gróffóðri. Líklega þarf að
takmarka samkeppni um átpláss ef
fóðrað er með fjölbreyttu gróffóðri
(2-2,5 kýr um átpláss). Með réttri
hönnun fjósa og vönduðum vin-
nubrögðum við gjafir má draga úr
neikvæðum áhrifum sem þessi
fóðrunartækni getur haft á gripi.
