Influence of eggshell density of fertile eggs and infectious bronchitis virus on performance and sanitary parameters of embryos and broilers

Key Points

• The study aims to investigate how eggshell density and infectious bronchitis virus affect embryos and broilers' performance and health.
• Examined the influence of eggshell density on embryo outcomes and broiler metrics
• Analyzed hatchability and key performance indicators like weight gain and feed conversion ratio
• Monitored broiler mortality rates in relation to virus presence and eggshell characteristics
• Lower eggshell density correlated with increased embryo mortality rates and decreased hatchability (p<0.05)
• Infectious bronchitis virus presence led to reduced weight gain and impaired feed conversion ratios
• Overall, broiler mortality rates were notably influenced by both eggshell density and IBV presence
