The researchers asked 70 experts from around the world to assess the welfare risks of the most common dairy and beef production systems in their own country.
“We hope our findings may encourage a more sustainable and responsible food consumption,” says Roi Mandel Briefer, a postdoc at the University of Copenhagen.
“The welfare is worse with cattle in the most common dairy production systems in opposition to cattle in the most common beef production systems. These findings contradict a very long and widely held belief in our society,” Briefer says.
It is the first time that these predictions are being tested, validated, and published. Experts’ ratings addressed all main aspects of welfare related to the animals’ basic health and functioning, feelings, and their ability to engage in natural behaviors.
“The higher welfare risk in the dairy sector is not limited to dairy cows—defined from first calving onwards—but also, to their calves. Experts rated the welfare risk of calves originating from dairy herds to be higher than that of calves originating from beef herds, regardless of the production goal, be it for red-meat, veal, or to replace the dam,” says Briefer.
The researchers expect that the welfare assessment is the same in organic production, because dairy in organic production are also used for more than milk, the key reason for the worse welfare.
Raising dairy animals in better conditions may certainly improve their welfare in some contexts, Briefer says. “However, if such measures are similarly applied to bovines in the beef herds, then they may retain their perceived higher welfare status.”
Reflecting on why the results point to reduced welfare for animals in dairy systems, Briefer explains that dairy production involves a higher degree of intervention, since dairy cattle are used to provide milk for human consumption, whereas the beef cows produce milk for their own calves.
The milk from dairy cows, produced in considerably higher volumes than in beef cows, is collected one to three times per day, often for 305 days or more per lactation. That has implications for how these animals and their calves are raised and managed. Early separation of calves from their dams, a common practice in dairy herds, is one example.
The study also notes that long-term genetic selection for high milk yield in dairy cows is recognized as a major factor causing poor welfare. In particular, it results in health problems such as lameness, mastitis, reproductive disorders, and metabolic disorders.
