Farmed game: Hearing
Farmed game
Fallow deer and red deer
Both fallow and red deer have funnel-shaped ears that can be directed independently of one another, and therefore they can be angled up to 150˚ for catching up where the sound comes from. The inside of the earflap is covered by hairs that are thought to aid in dampening wind noise.

Mouflon
Mouflons have good hearing, but it is not superiour to that of the fallow and red deers. The ear funnel is comparatively small, and they mainly rely on their good vision and good smelling.Wild boarsWild boars have excellent hearing, and the funnel-shaped ears make them able to determine the sound direction. For pigs, also see equine and bovine animals.
Ostriches
Ostriches have well developed hearing and are sensitive to sounds. Constant noise, even at low levels, must be avoided, and the animals should be protected against sudden sounds.
Remember
- Noise leads to stress and impaired animal welfare at the slaughterhouse.
- The animals are more affected by sounds they are not used to. Take into consideration that the sounds at the slaughterhouse are new to the birds!
