Sometimes, there is a need to reduce feed intake to conserve feed and/or to slow growth rate. This might occur when feed supply is going to be interrupted for an extended period of time. It might also occur when the movement of animals to market is delayed or impaired due to an animal movement standstill, such as could occur during a suspected outbreak of a FAD. It might also take place when access to harvest facilities is temporarily suspended or delayed. The objective then would be to humanely reduce feed intake, or energy and/or nutrient intake, in order to slow or suspend growth until the problem is resolved.
