  • Title: Influence of zinc bacitracin, light regimen and dustbathing on the health and welfare of broiler chickens.
    Author: Stub C, Vestergaard KS.
    Journal: Br Poult Sci; 2001 Dec; 42(5):564-8. PubMed ID: 11811906.
    Abstract:
    1. The influence of zinc bacitracin, an antibiotic growth promoter, and the combined influence of two environmental factors (8 h of darkness and access to sand) on health and welfare variables were studied in 96 broiler chickens (kept as pairs). 2. Chickens fed with zinc bacitracin (ZB) had a higher frequency of tibial dyschondroplasia (TD) and a higher frequency of dustbathing than chickens fed without zinc bacitracin. 3. When 42 d old, chickens exposed to 8 h of darkness and access to sand were heavier than chickens reared under continuous light and with no access to sand. 4. Fluctuating asymmetry was higher in the 'light/no sand' groups than in the 'night/sand + ZB' group. 5. There was a negative correlation between tonic immobility and weight and a positive correlation between weight and TD.
