Fumigation (1): how formaldehyde can affect hatchability

Fumigation with formaldehyde is a widespread and highly effective tool in the battle against contamination by viruses, bacteria and mould in hatcheries. However, it is not entirely without risk for the developing embryo, and a number of conditions (timing, ventilation, humidity, and temperature) need to be met in order to avoid that the gas adversely affects your hatchability. In a series of articles, we will explain why formaldehyde may reduce hatchability, look at methods of improving all aspects of the practice of fumigation and investigate alternative solutions.

Ventilation in the setter

Which is the dominant element for ventilation control: CO2 or humidity?

Egg storage: good practices

Upon arrival at the hatchery, eggs are stored for a number of days before incubation starts. This period of time can vary considerably between 0 to 20 or more days. To minimise embryonic mortality and maximise hatchability/chick quality, it is essential that optimal conditions are achieved in the egg holding room. The purpose of egg storage is to suspend development of the embryo until incubation is initiated. Incorrect storage will result in an increase in early deaths which are often misinterpreted as infertile eggs. In this article, we focus on the two most important parameters for egg storage: temperature and humidity.

Optimise your hatchery results through comparative trials

The only true way of achieving optimal hatchery results and ensuring they are integrated in the process chain is through comparative trials. It is therefore crucial that they are carried out accurately and efficiently. In this article, we listed some key elements for successful comparative trials.

Balanced loading of the setter

Sometimes, it is inevitable to load eggs from different flocks into one incubator. To avoid that this leads to uneven temperatures inside the setter and, consequently, decreased hatchability and chick uniformity, balanced loading is key.

Understanding the hatching egg

For many years, the hatcher was considered to be merely a ‘finishing’ machine. However, research undertaken by Petersime has shown that the hatcher can enhance and optimise what has already been achieved in the setter, resulting in gains in uniformity, quality, hatchability and post-hatch performance. This requires good program management.

Incubating by manual egg shell temperature measurements

Temperature is the most important incubation parameter, and allowing the egg shell temperature to dictate the air temperature during incubation is without a doubt an excellent method of operation. In hatcheries operating with S-line machines, Petersime’s OvoScan™ automatically and precisely makes the necessary egg shell temperature measurements, calculations, and adaptations, without opening the incubator’s doors. If OvoScan™ is not an option in your hatchery, you can manually measure the egg shell temperatures as an alternative. Read how to do this with optimal results and minimal damage to the embryos. 

The benefits of non-linear weight loss

One of the main benefits of single-stage incubation is the possibility to apply the non-linear weight loss system (NLWS), in which ventilation is reduced during the first 9 days in the setter and increased during the next 9 days. This article points out how NLWS works and why it is so beneficial. 

Configuring your setter temperature program

The standard Petersime OvoScan™ temperature program offers a “safe” starting point for general incubation. It achieves good hatch results with a high standard in chick quality. However, it is not the optimum profile for all flock types, ages, storage time, and many other factors that can affect embryonic development, growth and overall chick quality. Configuring the optimum temperature profile for your hatchery can only be done with site specific data analysis combined with the expertise of the Hatchery Manager/Company Incubation Specialist. However, there are some basic principles that should always be considered.

Choosing the correct air temperature in the hatcher after transfer

In previous articles such as “Understanding the Hatching Egg” and “Handle with care: egg transfer”, we discussed the hatching process and the effects of physical shock during transfer between setter and hatcher. However, there is another factor that plays an important role in terms of hatchability and chick quality: the thermal transition between setter and hatcher.

Updated S-line CO2NTROL™ profiles

For many years now, Petersime’s Embryo-Response Incubation™ systems have been providing significant gains in hatchability, chick quality and post-hatch performance. One of the key factors is the CO2NTROL™ system, which is standard installed on all S-line setters and hatcher configurations. Recent field trials and research have led to refinements of Petersime’s incubation profiles regarding CO2. These are based on two objectives: reducing early incubation mortality and improving chick yield. Chick yield is the weight of the chick at hatch as a percentage of the egg setting weight.  

Incubating at increased egg density

The poultry industry has seen many changes over a relatively short period of time, but none quite as important as the increase of average capacity of a hatchery. Only a few years ago, a hatchery with a setting capacity of 1 million eggs per week was considered large, whereas today we see hatcheries with capacities of 2, 4 or even 6 million eggs per week. With this growth come new demands, such as reduced capital costs, maintenance and land purchasing costs. A solution is to increase the egg density of the incubators.

Heat treatment during storage

In the process of incubating eggs on an industrial scale, egg storage is a key element that cannot be ignored or avoided. Long storage times (7 days or longer), however, inevitably lead to a significant decline in hatchability. In order to understand why heat treatment can partially restore hatchability losses caused by egg storage, as well as the limitations to this method, the biology of the early embryonic processes needs to be examined in detail.

Commercial application of heat treatment during storage

Last month, we explained why short periods of heat treatment in case of long storage times are beneficial for early embryonic development, zooming in on the biological background. In this article, we put this knowledge into practice: how can this treatment successfully be introduced in a modern-day hatchery?

Responsible disposal of hatchery waste

The chicken meat industry continues to grow globally; and so does the volume of hatchery waste: eggshell debris and fluff, infertile eggs, dead embryos, culled chicks, egg fluids, as well as wastewater from cleaning and disinfecting equipment and processing areas. In recent years, rising disposal costs, environmental regulations and awareness have created a need for hatcheries to find sustainable alternatives for waste management. There are various options for hatchery managers to convert their waste into value-added products such as compost, fertilizer, liming agents for soil amendment, biogas, medical products, and animal feed. This article explores some of these options.

Incubation of duck eggs without removal of cuticle

The removal of the cuticle has always been a common practice when incubating duck eggs. However, this removal involves a higher risk of contamination, possibly resulting in a huge negative impact on hatchery results. Petersime’s Dynamic Weight Loss System™ offers an alternative for the incubation of duck eggs, making the removal of the cuticle redundant, thereby reducing the risk of contamination.

BioStreamer™ Re-Store:  Impressive field results of hatch and post-hatch performance

The BioStreamer™ Re-Store warms up eggs for short periods during storage to minimize the losses in hatchability and chick quality caused by long storage times. Recently, several trials with the BioStreamer™ Re-Store were performed in a commercial broiler hatchery. The hatch and post-hatch performance was investigated and the results are extremely positive, what confirms the potential of this heat treatment technology.

BioStreamer™ Re-Store reduces early, mid and late embryonic death

The BioStreamer Re-Store™ improves the hatchability and chick quality of stored eggs. Previous field results proved that a Re-Store treatment enhances hatch and post-hatch performance (see E-news December 2014). New data from a broiler hatchery confirm that the Re-Store improves hatchability by reducing early, mid and late embryonic death.

雏鸡存放: 4 个重要原则




出雏期间 CO2 含量升高: 揭露真相

多年来,在孵化期快结束时 CO2 含量升高被认为不利于禽类的胚胎发育——但事实并非如此。在自然情况下,母鸡孵化环境下测出的 CO2 含量至少为 0.4% 或 4,000 ppm,通常更高。这是外界空气中正常 CO2 含量的十倍。实际上,母鸡在孵蛋时会阻止种蛋周围的气流流动,来创造一个受保护的环境,使胚胎能够在最佳条件下发育。 为了更好地了解这一过程, Petersime 开始确定出雏期间的最佳 CO2 含量和提高该含量的正确时机。

孵化场废弃物: 如何减少、重复利用或回收(等等)?



自从孵化行业从巷道式孵化升级到箱体式孵化以来,环控系统就成为孵化场运营不可或缺的部分。从本质上讲,环控系统在箱体式孵化场的环境控制方面发挥着举足轻重的作用,从而帮助孵化设备实现了最佳产量。 环境控制的重要性远不仅仅在于调节孵化器和出雏器的空气,因为在箱体式孵化场中,控制每个房间从接收种蛋到雏鸡分配期间的空气状态对于取得最佳的孵化效果都至关重要。








在现代家禽业中,箱体式孵化设备已经是一个发展成熟的概念。随着家禽肉类需求量的增加以及食品安全和质量标准的拔高,越来越多的传统巷道式市场也开始对采用Embryo-Response Incubation™ 等先进技术的箱体式孵化系统表现出浓厚的兴趣。为了解决有关为何选择箱体式孵化设备而不是巷道式孵化设备的任何疑虑并阐述清楚箱体式孵化设备的真正优势,巴西LAR Cooperative 与Petersime 联合开展了广泛的对比试验。
