碩士 / 國立高雄大學 / 創意設計與建築學系碩士班 / 103 / The purpose of the research is to explore the influence of various chicken range settings and feeding management techniques on broiler chicken (Gallus gallusdomesticus) growth and development as well as the overall environment. This research studies the growth of boiler chickens in different age groups based on range structures and environment. The research focused on three types of free ranges, each with approximately twenty thousand broiler chickens. Traditional free ranges are compared with ranges with wet pad cooling systems.
Cost-benefit analysis focuses on illumination, rooftop vegetation, ventilation and water management. This study explores environmental influences on chickens during the first five weeks after hatching and moving to a range. Broiler chicken growth is divided into four phases for the purpose of this study. Temperature control, health management and biological safety are most important in the first stage. Chicken feed as well as water supply and management are crucial during the second stage when growth is the most rapid. Temperature and humidity are important during the third stage, when chickens experience slow growth. Ventilation, litter and heat stress are important in the fourth stage, when broiler chickens are mature and require weight control. The research investigates environmental changes in each stage during the first five weeks following hatching. It also provides differences in feeding records and cost-benefit analysis.
Analysis of broiler chickens’ weigh growth during the first five weeks following hatching shows that with physical facility improvement, free ranges can effectively increase chicken growth and development. It can also reduce incidence of diseases and elevate feeding quality, which increases quality and output of chicken for chicken farmers.
Keywords: chicken, range management, free range, chicken range with wet pad cooling system, growth and development, feeding management technique.
