Poultry technology solutions receive silver medals in EuroTier innovations awards

LinkedIn +

EuroTier was cancelled in November to be held virtually in February 2021, but its traditional innovations awards were still announced at a virtual preview event last week. In total show organisers DLG made eight awards including one gold medal and seven silver medals from a total entry of 80 innovations.

Two of the silver medals were presented to poultry products including automatic egg sexing technology and an egg sorting unit.

SELEGGT Circulus sampling system

Egg-laying chicken genotypes are considered unsuitable for producing poultry meat, due to lower product quality and cost effectiveness. For this reason the male chicks of these breeds are generally not reared. However, as the culling of day-old male chicks has become a societal and political issue, with a ban on this practice being considered, the industry is seeking alternatives to this process.

Last month we covered Israeli company Soos technology’s novel ‘sex change’ approach (and US$1 million prize). However, the most extensively developed and commercially useable method right now is in-ovo sex determination with hormone analysis on the eighth or ninth day of incubation. The Seleggt Acus sampling system, developed by respeggt GmbH for this purpose, is already in practical use. Sampling the test fluid from the allantois using a needle, this system is only partially automated. There is also a risk of injuring the allantoic membrane which can lead to a reduction in the hatching rate. The hourly capacity of a single sampling unit for that system is around 600 eggs.

A step forward – non-invasive egg sampling

The innovative Seleggt Circulus system is a significant leap forward compared to the predecessor system. Operating fully automatically, the allantoic fluid samples are generated in a non-invasive way. The overall sampling time has been reduced to just one second per egg as there is no longer a need to clean any sampling needles.

In a three-shift operation sequence (with an operating time of 20 hours per day), one Seleggt Circulus sampling unit has a weekly capacity of 360,000 hatching eggs, corresponding to 150,000 to 180,000 laying chicks, a significant increase in performance in comparison with the Seleggt Acus system.

Non-invasive sampling and the vastly increased hourly capacity have established the prerequisites for universally replacing the previous culling of male chicks in hatcheries with in-ovo sex determination.

NECTRA SAS Egg Refilling System

It’s an all too common factor on egg farms and hatcheries that manually sorting eggs on trays takes up a lot of time. The hatching eggs from broiler parent livestock farms are delivered to central hatcheries, where they are sorted according to quality and weight before being placed into the incubator. In addition, eggs that are not positioned with the blunt end pointing upwards in the tray have to be turned. This leads to a high number of incompletely filled trays that have to be manually refilled. Often, the eggs are also transported on conveyors where they can come into direct contact with one another, possibly resulting in damaged shells.

With the new system presented by Nectra SAS, the eggs are transferred from the delivery trays to egg moving cups that move freely on a transport conveyor. Here, the eggs can be automatically and individually sorted according to quality and weight and can also be turned if they are positioned incorrectly.

The freely moving egg cups are backed up for transfer to the hatching trays, unoccupied egg cups are automatically removed and the remaining, filled egg cups are then transferred automatically to the hatching trays so that no gaps occur.

The system significantly reduces the likelihood of damaging the egg shells and automates the hatching tray filling process. This considerably lightens the workload and leads to an improvement in hatching rates in the broiler chick hatcheries.
