Does anyone have any knowledge on rabbit diseases? - rabbit cages commercial

My husband has recently started raising rabbits for meat and has problems with some dying. You have no symptoms until we are dead. These are symptoms of a healthy weight, eyes and ears are clear, no diarrhea, respiratory or neurological. Let's find dead in their cages. All the feeding of a commercial rabbit food and access to clean water at all times. A rabbit in a cage, and cages are cleaned at least twice a week. They are in a shed with adequate ventilation and not too warm, fully accommodated. Any suggestion is welcome. We have rabbits for years without problems, and it is frustrating!
