Short summary
As part of the “GreenCalf” project, we are investigating how much a new feed supplement can reduce methane emissions from growing young cattle.
When ruminants, such as cattle, break down fiber-rich feed, the greenhouse gas methane is produced. The levels of methane produced can be reduced using various feed additives. Various feed additives have been tested and are being tested worldwide. In this experiment, a new feed additive developed by a Swedish company is being tested.
In this project, we intend to compare, under controlled conditions, the feeding of two levels of the AB-01 feed supplement with a third group that receives no feed supplement to a total of 54 young Holstein bulls during 2025–2026. We will evaluate feed intake, growth, and methane emissions from weaning to slaughter.
The sub-study at Götala is part of a larger, primarily Danish, project called GreenCalf. The sub-study at Götala is led by Aarhus University in collaboration with SLU, Agteria, SEGES, and Danish Crown.
