Fully automated determination of the fertilization rate of salmon eggs
OCT – a high-tech procedure from ophthalmology, used for fully automated, three-dimensional detection and analysis of the cell cluster of fertilized salmon eggs.
In commercial fish farming, such as the breeding of Atlantic salmon, fish roe is artificially fertilized in special containers. After 24-48 hours, a representative number of eggs is randomly selected, removed and treated with diluted acetic acid to assess the resulting fertilization rate per incubator. Through this treatment the eggs lose their natural opacity, become transparent and can be examined under a light microscope. Until now this inspection has been done manually and is heavily dependent on the individual experience and knowledge of the operator. Additionally, structural changes, caused by treatment with acetic acid, can lead to interpretation errors in the microscopic evaluation.
A fully automated device for the non-contact examination of fish eggs by means of Optical Coherence Tomography (OCT) allows capturing tomographic image data similar to Computer Tomography within a matter of seconds. The scanned fish eggs remain viable and can be examined in their natural state. To this end, the eggs are transferred into a water filled sample container, which is designed to let the eggs slide into fixed positions for measuring. The OCT probe above the sample container is positioned fully automatically above the egg to be tested. The camera integrated in the probe detects blastodiscs in the fish eggs and provides the coordinates for the subsequent OCT measurement. The data obtained are then evaluated and logged online. With the help of the determined fertilization rate, it is then possible to calculate the expected number of hatching eggs per incubator. The evaluation of the developmental state of the fish embryo at a later point in time is also possible.
Hygienisation of hatching eggs using accelerated electrons.
eBeam – killing harmful bacteria, viruses and fungi to protect the hatching chick.
The aim of the modern poultry industry is to produce poultry and poultry products as economically as possible. This results, among other things, in very high demands on hygiene measures, on the one hand to maintain animal health and on the other hand to minimize the microbial contamination of poultry products. An essential starting point for this is the improvement of hatching egg hygiene, for example in broiler and fattening poultry production. By specifically treating the calcareous shell of the hatching eggs, bacteria, viruses, and fungi are deactivated, thus protecting the hatching chicks from contamination with pathogenic germs. The chain of possible transmission to the animal or human via the poultry product is thus interrupted. This opens up further areas of application for disinfection processes, such as for the production of Specific-Pathogen-Free Eggs (SPF) for the vaccine industry or for commercial egg production. Currently, the most widely used process for surface treatment of hatching eggs is fumigation with formaldehyde (HCHO). However, due to the toxic and carcinogenic effects of formaldehyde, this method is highly controversial. Application bans are being discussed, but due to lack of alternatives, no ban has been implemented yet.
The treatment of hatching eggs by means of low energy, accelerated electrons. These are generated with the help of special open or pumped electron beam tubes, hit the surface of the eggs and penetrate the porous calcareous shell. This allows even invisible, hidden germs to be killed while the inside of the egg remains untouched, and the chick’s development can proceed normally. High hourly throughputs are achieved by treating several hatching eggs at the same time.
Detection of SINS-associated changes in suckling piglets
Thermography – Detection of inflammatory skin changes in newborn suckling piglets for the early detection of deficiencies in husbandry or feeding of parent animals.
The aim of pig husbandry, which has become highly specialized, is to develop practical and economically viable husbandry concepts for large numbers of animals and paying attention to animal welfare at the same time. In addition to the occurrence of injuries, for example in the course of antagonistic behavior between animals, the so-called Swine Inflammation and Necrosis Syndrome (SINS) is increasingly coming into focus. The pathological changes that can be observed on the animal, occur already in newborn piglets in various parts of the body. The etiology of SINS is still largely unclear. In addition to a genetic disposition, metabolic and feed-related causes are suspected.
A mobile measuring device for semi-automated imaging in the barn and for documenting SINS problems in suckling piglets. Based on the so-called infrared thermography, image data of the affected body areas are recorded and assigned with a corresponding score. The digital photo taken in parallel, shows the identical image area and can be overlaid with the IR image. In addition to the visualization and evaluation of the temperature distribution, this also enables the exact geometric classification of the inflammatory changes and necroses typical for SINS. In addition, the recorded data sets are used to create a classification algorithm that allows automatic determination of SINS severity level of the individual animal. This makes the device not only useful for veterinarians, but also as a diagnostic tool for animal owners in the farm practice.
