The Effects of Setting Eggs Small End up on Hatchability and Chick Performance

Eggs are incubated in setter trays for most of the incubation period. Three days before hatch, the eggs are transferred to hatcher baskets. In the setter trays the eggs are placed vertically with the air cell (large end) up, while the eggs lie horizontally during hatching. In normal development, the embryo begins to turn to

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

Impact of Hairline Cracked Eggs on Hatchability and Chick Performance

In general, good quality eggs are selected and placed for incubation. This means that only clean eggs with shell intact should be placed on the setter trays. Dirty or floor eggs and eggs with visible cracks are removed and not placed. Eggs with hairline cracks might often not be recognized and will, consequently, be placed

Hatching Egg Transport! The Best Procedure

Breeder farms are often situated away from the hatchery. The distance between the two sites therefore becomes an important consideration when planning the transfer of eggs to the hatchery. Typically, deliveries vary from daily to not less than twice weekly, as increased storage time has a negative impact on hatchability and chick quality. Egg transport

Care of the Hatching Egg: From Nest to Farm Store

  A healthy, well managed breeder flock, receiving a balanced feed ration, will produce good quality hatching eggs. At the moment an egg is laid, it contains an embryo of 30,000 - 60,000 cells. At that point in time, each cell is already programmed for its future function. With the best of care, the hatching

Managing Fertility: Good breeding Practices

The percentage of fertile eggs is one of the most important parameters influencing the economic performance of a breeder flock. An embryo can of course only develop from a fertile egg. Fertilization takes place – and thus can only be influenced on - the breeder farm. When we consider fertility, we usually think of the

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

Avian Influenza

It is a viral disease caused by "Orthomyxo virus". There are two types of AI which are characterized by low pathogenic avian Influenza (LPAI) and highly pathogenic avian Influenza (HPAI). Clinical Signs  Most commonly found clinical signs which are found in the birds affected by AI are coughing, sneezing, nasal and ocular discharge, rhinitis (sticky

Hatching Egg Quality

Hatchability and chick data are the most important references for optimizing incubation management. The age of the flock, number of storage days and incubation program are typically included in the analysis and optimization of hatchery results, but very often, insufficient attention is paid to the quality of the hatching eggs. While external quality is usually
