Comparative Analysis of Zootechnical Performance in Broiler Chickens Across Different Technological Rearing Systems

Abstract

This study conducts an in-depth investigation into the zootechnical performance of broiler chickens reared under diverse technological systems, against the backdrop of a globally increasing demand for chicken meat. The research addresses how the rearing system, along with factors such as nutrition, farm management, the rearing environment, and genetics, impacts the yield of chicken meat production. By comparing intensive, semi-intensive, and extensive growth systems, the research aims to identify optimal strategies that ensure efficient and sustainable chicken meat production, maximizing yield and quality while also considering animal welfare and environmental sustainability. The analysis encompasses the evaluation of daily weight, feed conversion ratio, and uniformity across different systems, as well as the examination of environmental homogeneity using the Student's t-test to highlight significant differences between batches. The findings offer valuable insights into the impact of the rearing system on zootechnical performance, indicating that the intensive system is characterized by superior yields and a preferential development of the breast. Moreover, the study highlights the significance of the interaction between genetic and nutritional factors and how these elements, together with the choice of rearing system and healthcare practices, contribute to the optimization of production.
