![]() These differences are even present during the embryological stage and can require different temperature environments. The turkey industry is also unique in itself because of the varying market requirements: some markets prefer small-framed turkeys, some medium-framed, and yet others want very large-framed birds. Turkeys eggs are especially sensitive to temperature This has led to a specific turkey eggshell temperature programme that is unique compared to other species. Trials with turkeys have shown that the critical transition from the endothermic to exothermic phases of incubation require a lower temperature than other species. Not achieving this target usually points to an unhealthy hatchling.Īn automated eggshell temperature measurement device makes it possible to control the environment of the developing and constantly changing embryo so that it can thrive in an ideal environment for all its needs specific to its stage of development. The ideal weight loss at transfer is roughly 10% of the egg’s weight when it first commences incubation. This is the air cell the hatchling first breaks through when it starts to hatch. Weight loss in a fertile egg manifests itself in the size of the air cell on the blunt end of the egg. In this way, the environment can be tailored to the specific and ever-changing gaseous exchange requirements of the embryo to stimulate strong vascular development and achieve target weight loss figures.Ī developing embryo sheds two waste products – CO 2 and water – leading to weight lossīy shedding water progressively, an egg reduces in weight. When incubation commences, measuring and applying set points to CO 2, as well as making the CO 2 level guide the ventilation rates, can spare the embryo from any dramatic changes to its gaseous environment. Not only does this procedure improve viability of the fertile eggs it also lends itself – in combination with setter and hatcher technology – to achieving a more narrow hatch window.ĭistinctive setter and hatcher technologies Subsequent Re-Store treatments on eggs stored for an extended period of time improve hatchability by restoring cell growth and survivability of eggs returning to storage. Trials with research partners have proved the benefits of using heat treatment for turkey eggs.įlock 1 comparative trial: Re-Store treatment versus no treatmentįlock 2 comparative trial: Re-Store treatment versus no treatment One way of preventing early embryological loss in turkeys is to use heat treatment during storage in a dedicated Petersime BioStreamer™ Re-Store machine to advance embryological development to stage thirteen and so unify the overall spread of stages. Comparing turkey eggs to chicken eggs shows that almost 60% of turkey eggs are in pre-development stage ten when delivered to the hatchery. Eggs in earlier stages tend to be more susceptible to perishing during storage. Research suggests that the stage that offers the best survivability of the embryo during the storage period in the hatchery is stage thirteen. The different stages of embryological development were identified and classified by Eyal-Giladi and Kochav, and Hamburger and Hamilton. A possible cause is the wide spread of embryological development in the turkey eggs when they are delivered to the hatchery. And yet, the viability of these fertile eggs often turns out not to reach its full potential. Artificial insemination means that fertility rates have the potential to be very high. ![]() Natural mating in turkey flocks is rarely practiced.

Embryo-Response Incubation™, as this method is called, involves technology that caters explicitly to the specific demands of different bird species. We always try to emulate the experience the embryo has in the nest. The natural hatching process is the starting point of Petersime’s incubation philosophy. Hence, a suite of incubation equipment that allows for fine-tuning of the processes and parameters is more than worth the investment. Turkey eggs have a high incubation success rate when all the species-specific areas of incubation are managed correctly. The specific requirements and sensitivities of turkey egg incubation ![]()
