All species are sensitive to abrupt diet changes.
When necessary, changes should be gradually introduced in small, incremental amounts. Feeders and water sources must be designed to allow easy access for all animals in a particular pen or grouping. Feeders and water containers must be routinely cleaned and kept free of sharp edges or exposed nails which might injure the animals. Compounds such as paint, pour-on insecticides, or antifreeze, which are toxic MUST NOT be kept in feed storage areas. A healthy animal will be alert.
