A comparison of in-vivo and in-vitro methods for assessing the digestibility of poultry by-product meals using barramundi (lates calcarifer); impacts of cooking temperature and raw material freshness

Rendered terrestrial animal by-product meals (ABPM) are commonly used in aquafeeds for fish and shrimp. However, the nutrient composition and digestibility of these products is often variable due to differing processing conditions. As such, the aquafeed industry could benefit from technologies that rapidly assess the nutritional quality of ABPM prior to purchase and their incorporation into aquafeeds. To be useful, new technologies would need to...
