17 17 LOHMANN TIERZUCHT › MANAGEMENT GUIDE Monitoring & Profiling Data recording should be part of the everyday management practices in alternative systems. This should be- gin on the day of placement in the rearing facility. Hens in alternative systems are ex- posed to many vectors that can im- pact on development and productiv- ity therefore we must use everything in our arsenal to assist us should a challenge occur. Collecting and analysing daily data is the key to detecting and resolving any management issues that may arise. All sites should create their own monitoring programs. These can be as simple as paper records or utilis- ing latest technologies that can re- cord and benchmark data such as those LOHMANN TIERZUCHT have available. Monitoring programs should cover not only the obvious such as feed and water consumptions, body- weights and production data, but also anything that may influence development and production such as internal and external temperature recordings and humidity levels. The more data that is available to you the easier it will be to carry out any investigations into issues arising in the flock. Investigative analysis is the art of identifying trends and processes of cause and effect. The ability to use the data compiled in this way is beneficial not only for the current flock but also to help identify trends from flock to flock.
