Effects of temperature and dairy cattle excreta characteristics on ammonia emissions from a simulated concrete floor

| Summary: | In warm climate areas, such as the Mediterranean region, significant amounts of ammonia may be released to the atmosphere from urine and faeces deposited in concrete floor areas of dairy cattle housing systems. In many farms these concrete areas are shared by cattle of different ages and at different stages of the production cycle. The objectives of our study were to assess the effects of temperature and of excreta characteristics (i.e. from heifers, dry cows and lactating cows) on ammonia emissions, using a laboratory system simulating a dairy house concrete floor. |
