Jason, why are you asking this question? The difference seems obvious. If you noticed the difference in labeling from old bags and new and that is causing you concern, let me just say ... it probably means nothing. Why would a producer want to label a group of animal protein sources under a single ingredient moniker (animal protein products)? Good reasons include trade secrecy. Whatever the stimulus for changing the labeling, they are not doing anything that the competitors are not already doing. The only labels I have ever seen where fish meal is listed separately as an ingredient were Optimal. Any good feed has fish meal, but I can understand why producers do not want to be too detailed about their formulations. It is just as likely that nothing has changed as any other possibility of change. Keep in mind, other possibilities also include improvements to digestibility and consequently improvements to conversion/maintenance properties.
