Managing Incubation Temperature to Combat Increased Early Mortality

As a breeder flock ages, the number of ‘clear’ (infertile) eggs increases as a result of decreased fertility and increased early mortality. Consequently, with higher numbers of clear eggs, a higher proportion of the heat produced by developing embryos in the fertile eggs is absorbed by the ‘cold’ clear eggs placed around them. Embryonic temperature

Finding Optimum Incubation Temperature

When a hatchery manager talks about incubation temperature, he or she refers to the temperature set point at the controller of the incubator. This temperature set point regulates the temperature of the air stream along the incubator’s temperature sensors. If the air temperature is too high or too low, the incubator controller adjusts the cooling

How Hatchery Management changes when starting Single-stage Incubation

Management in a multi-stage hatchery is based on a daily routine of setting eggs according to a strict setting schedule per setter type. The common principle for establishing a setting schedule in a multi-stage incubator is based on the need to transfer metabolic heat from more developed embryos to the less developed, heat-demanding embryos in

The Importance of Preventing ‘Sweating’ Eggs

Sweating’ of eggs refers to the phenomenon of condensed water sitting on the egg shell surface. This occurs when cold eggs are suddenly exposed to a higher environmental temperature. The warm air with a certain moisture content cools down rapidly directly around the colder eggs. Since cold air contains less water than warm air, relative

Storage of Hatching Eggs! Maintaining Quality

Egg storage is the time between oviposition (laying) and the start of the incubation process for hatching eggs. Optimal hatching results and chick quality can be achieved if eggs are set after an initial adaptation period of about 1 to 2 day(s). This allows carbon dioxide to be released from the egg, which increases albumen

Establishing True Fertility in Hatching Eggs

If it comes to discussions on fertility two different definitions are practiced. A true fertile egg contains a well developed germinal disc (blastoderm), which indicates that the oöcyte, or zygote, was fertilized and an embryo developed during egg formation. Secondly, in the practice of the hatchery fertility is often based on candling, whereby all clear
