High tech udder scanner adds more precise data
Geno is trialing new scanning technology as part of a research project that will enable it to collect more comprehensive and precise data on udder traits.
This will be used in its breeding programs and accelerate the progress made in improving functionality, health and welfare traits within Norwegian Red cattle.
The scanning system includes a newly developed hand-held 3D camera which is mounted on a stick together with a small computer. “The camera is placed on the floor underneath the cow udder and makes it possible to take images of the teats and the udder from the bottom up perspective,” says Geno researcher Øyvind Nordbø, based at the co-operative’s main office in Hamar, Norway.
“The operator is able to see the image on the computer screen and record it alongside the animal’s ID.”
This camera records pictures and data of the cow’s udder within a few millimeters of accuracy and the images can be used to build a 3D digital model.
New camera technology
The project, that uses this advanced scanning technology, is being carried out by Geno in collaboration with the Norwegian pig and beef breeding organizations, Norway’s University of Life Science and Technology and the University of Auckland, with support from the Norwegian Research Council.
The initial trial, which started in September 2019 and will run until the end of April 2020, is using the new camera technology to scan around 1500 cows in Norwegian dairy herds. Technicians will also score cows visually and this data will be used along with the scanned images in computer systems to build up algorithms through advanced machine learning.
“These results will improve our accuracy in predicting udder traits within our breeding programs. We will also store the images for future research, allowing us to develop new traits for animal breeding,” he adds. “And looking ahead, we hope to develop additional camera systems that can make high quality 3D images of the legs and the body.”
Replacing traditional visual scoring?
“If we succeed with this, we will be able to replace traditional visual scoring systems with a digital system based on 3D imaging techniques.”
The technician scoring system has worked well in the Geno breeding programs for many years, and has provided good data for developing health and functionality traits, as well as production traits.
“But the more precise data that will be available from the scanners will accelerate our progress and give the Norwegian Red breeding program a clear advantage.”
Breeding for better health
Geno is putting emphasis on traits that will breed cows to meet the changing demands of its farmers in Norway and in its international markets. “Many want to breed cows with uniform udders and teat placement that are more suited to robotic milking machines. Udder and teat characteristics are also linked to cow health, welfare and sustainability which further emphasizes the importance of genetic improvements in these areas.”
Norwegian Red cows are well-known for their high health and fertility characteristics, thanks to the selection pressure placed on these traits in the past 30 years. “Other breeds, particularly the Holstein, have been compromised in the pursuit of higher production,” says Mr. Nordbø.
“Norwegian Red genetics are frequently used in breeding programs across the world to restore and improve these key functional traits. More detailed data that will be available from this new technology offers our farmer producers great opportunities to breed better cows for their systems and to improve the sustainability and efficiency of their units, in Norway and in herds internationally,” he adds.
