The Effect of Varying Distances from the Wind Turbine on Meat Quality of Growing-Finishing Pigs

This important paper examines the impact of wind turbine noise on farm pigs and their meat quality. The research found that some level of stress from turbine noise during the fattening period and prior to slaughter has a detrimental effect on meat quality. The abstract of the paper is provided below. The full paper can be accessed by clicking the links on this page.

ABSTRACT

This study was conducted to assess the effect of rearing pigs at three different distances from a wind turbine (50, 500 and 1000 m) on the physicochemical properties and fatty acid composition of loin and neck muscles. The experiment was carried out on 30 growing-finishing pigs, derived from Polish Landrace × Polish Large White sows mated to a Duroc × Pietrain boar. The results obtained during the noise measurement showed that the highest level of noise in the audible and infrasound range was recorded 50 m from the wind turbine. Rearing pigs in close proximity to the wind turbine (50 m) resulted in decreased muscle pH, total heme pigments and heme iron as well as reduced content of C18:3n-3 fatty acid in the loin muscle. Loins of pigs reared 50 m from the wind turbine were characterized by significantly lower iron content (6.7 ppm g-1) compared to the loins of pigs reared 500 and 1000 m from the wind turbine (10.0-10.5 ppm g-1). The concentration of α-linolenic acid (C18:3n-3) in loin and neck muscles decreased as the distance from the wind turbine increased. Avoiding noise-induced stress is important not only for maintaining meat quality but also for improving animal welfare.
