BIOLOGICAL INSIGHTS INTO THE INFLUENCE OF BREEDING TYPES ON BEHAVIORAL TRAITS IN BIRDS

This study was conducted in the bird fields of the Department of Animal Production, College of Agriculture, University of Anbar, to investigate the effect of different breeding types on desirable and undesirable behavioral traits in birds. The study focused on the impact of roosting behavior, sand bedding, theater systems, and other breeding methods to determine which approach best enhances animal welfare. Additionally, the research explored the influence of breeding types on behavioral, physiological, and productive traits. A total of 120 ROSS 308 birds, with an average weight of approximately 40 grams, were randomly assigned to six treatments. The treatments were as follows: T1 – indoor rearing with free theater systems and perches; T2 – indoor rearing with perches using conventional methods; T3 – indoor rearing with free theater systems; T4 – control group (indoor rearing with regular methods); T5 – outdoor rearing with perches; and T6 – outdoor rearing without perches. Each treatment consisted of 20 birds, with each bird treated as an experimental unit. To simulate natural conditions, sand flooring was utilized in the free theater treatments. Birds were fed using an ad libitum system. The results provide insights into the influence of these breeding types on bird behavior and welfare, with important implications for optimizing physiological and productive outcomes.
