Bioacoustics is the study of the production, transmission and reception of sounds emitted by animals. Most animal welfare studies aim to reduce potential negative experiences from the farm environment that could threaten animal health by allowing improvements to be made to environmental factors such as light, noises, flock density, facilities, disease prevention, to define all those stress factors that could negatively affect animal welfare.
One of the most relevant and first stress factors to which newborn broilers are subjected is the prolonged fasting caused by the routine practices to which they are subjected in the hatcheries before reaching their destination in the farms. Prolonged deprivation of water and feed has long-term negative effects on the health and behavior of the chick, affecting its growth and the correct functional development of the gastrointestinal system.
The objective of this preliminary study is to simulate fasting during the first two days of life (48 hours) of newborn chicks in a control group without early feeding and a second group administered a complementary gel feed, Licuicel® Complex, to assess the improvement in the health and welfare of the birds in both groups. Acoustic measurements have been made analyzing and comparing the difference in acoustic patterns between the two groups using metrics to empirically detect the health status of the animals, relating it to the hematological results obtained.
