17 Get the barn ready for new pigs. Cleanning: 4 elements Time Fiber Fat Protein Mineral Energy Temperature chemistry

18 Get the barn ready for new pigs. Dry Barn: 1. Move all visuel water 2. Outdoor temperatur > Ventilate with a lot of air. 3. Outdoor temperatur < Use ekstra heating m 2 barn x 3 kwh = 480 kwh kwh/8 = 60 liter

19 Get the barn ready for new pigs. Dry Barn: Air with 70% moister at 11 0 = 7 g/l Air with 70% moister at 30 0 = 21 g/l
