The dairy sector is urged to reduce negative environmental impacts. But dairy is not only milk: depending on the production system and cow breed, relevant amounts of meat as by-product result. How can emissions thus be allocated to milk and meat?
The available forage, climatic conditions and the measures for reducing ammonia emissions can adversely affect protein supplies for suckler cows. What is the impact on the weight and intake of the cows and their calves?
Persistent organic pollutants may accumulate in the tissues of suckler cows and their calves. Agroscope and Empa studied the processes by which these undesirable substances accumulate as well as the decontamination of previously exposed animals.
