LAITAT M., VANDENHEEDE M., NICKS B.Abstract :
Among the most important elements of the nursery pen design, the feeder allows or not the optimisation of pigs’ performance. Two principal design features can characterize a feeder : the way pigs will be fed (wet, dry or wet/dry) and its capacity, which depends in turn on the trough length or the number of feeding spaces (mono - or multi-space feeder and communal trough). To determine the number of pigs that can be accommodated per feeder, the daily time spent per pig at the feeder – depending on pig size and feed delivered – must betaken into account .
Recommendations of 4 to 10 weaned pigs per feeding space are generally given. Pigs are able to adapt their eating behaviour when crowding occurs but suboptimal situations may reduce feed intake and productivity and even impair welfare. Some particularities of the feeder such as limited depth, feeder gap opening, lip height, side panels or protective crate can limit feed spillage and/or agonistic interactions at the feeder. Feeder position in the pen should prevent pigs to be disturbed while eating and allow free movement of penmates. Get the PDF Contact person : mlaitat@ulg.ac.be |
