Reports of distressed cows and crying farmers have raised concerns about the feed additive Bovaer, which is used to reduce methane emissions from dairy cows.
In response, a Danish University has launched a study to investigate its effects, reports Videnskab. The project has been commissioned by the Danish Ministry of Food, Agriculture, and Fisheries. It will involve more than 70 dairy herds across the country. Researchers will focus on milk production and the health of the cows, according to a university press release.
A Better Understanding
The study will use performance control data, which records each cow’s milk output 11 times a year. By comparing data from before, during, and after the use of Bovaer, the researchers can see if there are any changes. They will look at both individual cows and entire herds to understand the overall impact.
The project will be led by Associate Professor Niels Bastian Kristensen from the Department of Animal and Veterinary Sciences at Aarhus University. He said the project is needed to respond quickly to the concerns of farmers. “This study will give us a much better understanding of the wide differences in how dairy producers experience using Bovaer,” Kristensen said. “It will also help us examine reports of negative effects more closely.”
The Effects of Bovaer
The main goal is to determine how Bovaer affects the cows’ bodies and health. The researchers also hope to identify areas that need further study.
In addition to this project, Aarhus University is conducting a separate study focused specifically on animal welfare for cows fed Bovaer. The team will observe several aspects of the cows’ behavior. They will look at how active the cows are, how they lie down and move, and their social interactions. They will also study comfort behaviors and monitor how much and how they eat.
Together, the two studies aim to provide a clearer picture of Bovaer’s impact. The findings will help farmers and regulators understand whether the additive is safe for cows and how it affects their well-being. The research may also guide future policies or recommendations for the use of Bovaer in dairy farming.
