Some bottlenecks forimplementing SAT§ In-houseSATmay require re-construction of animalhousing

§ In-houseandIn-storage SATs may have higher demand onconcrete quality (WP2)

§ Economy?Benefits andcosts will bestudied inWP5.

§ Safety?Need of extratraining with some SATs.

§ Need of extrastorage capacity because of foaming instorage.
