Experienced stockpersons become skilled at recognising and responding to the distress sounds emitted by farm animals in adverse situations. However, there are times when the stock manager cannot be present in the pig buildings and would find it useful to have a remote warning device to notify of any crisis,disaster, services failure, farm theft, injury or outbreak of fighting affecting the pigs.
A new device, called STREMODO® has been developed to monitor the sounds occurring in swine barns or livestock transport vehicles and provide early detection and warning whenever the animals come under stress.
The monitoring system is based on a sound recording with mathematical analysing and processing of the sound frequencies and amplitude. The device detects and warns of a specific frequency spectrum associated with distress vocalization of hogs.
The system is intended to give hog producers an early of stressful experiences occuring to the pigs, so that action can be taken before the welfare of the pigs and the economic viability of the swine farm enterprise is unduly compromised.
It might also be used in pork quality assurance schemes - data could be made available to reassure consumers that their pigmeat comes from low-stress farm sources.
