Question: 1 / 515

If a late dead problem is identified in the hatchery, which factor should be investigated first?

Egg size

High/low setter temperatures

When a late dead problem is identified in the hatchery, the primary factor to investigate first is the high or low setter temperatures. Temperature plays a crucial role in the incubation process, as it significantly affects embryo development. If the temperature is not maintained within the optimal range, it can lead to various issues, including improper growth rates and increased mortality during the later stages of incubation.

Investigating setter temperatures first helps identify whether heat stress or inadequate temperature has caused the late deaths. High temperatures can accelerate metabolism, leading to premature hatching or developmental problems, while low temperatures may result in slow development and increased susceptibility to infections or other stresses. Addressing temperature control is vital for ensuring a successful hatch and minimizing losses associated with late dead embryos.
