The use of various protein sources (industry by-products, proteaginous) in poultry diets requires a greater understanding of protein digestion mechanisms. The aim of this study was to characterize the molecular actors required for protein digestion in broilers fed 4 different diets containing soybean meal, rapeseed meal, pea, or corn distiller's dried grain with solubles as the only protein sou...

A spatial analysis was carried out in order to analyse the reason why the risk of Bovine Spongiform Encephalopathy (BSE) was spatially heterogeneous in France, during the period following the feed ban of Meat and Bone Meal to cattle. The hypothesis of cross-contamination between cattle feedstuff and monogastric feedstuff, which was strongly suggested from previous investigations, was assessed, ...

Vegetable proteins such as soybean meal, canola meal and lupins are widely used as the main protein source in poultry diets. However, there is only limited information on the nutritive or anti–nutritive effects of indigestible non–starch polysaccharides in vegetable proteins. This review discusses a number of experiments which investigated the effects of feed enzymes on the utilisation of non–s...

With the general objective of optimizing internal nutrient recycling, circular multitrophic food production systems, e.g., combining fish, plant, and insect larvae production, rely on quality composition sustainable nutritional inputs. Therefore, differences in dissolved solid excretion patterns produced by Nile tilapia (Oreochromis niloticus) reared recirculating aquaculture systems (RAS) with...

Replacement of fishmeal (FM) with alternative plant proteins, especially soybean meal (SBM), can cause a diarrhea-like symptom in rainbow trout (RBT), characterized by very fine fecal particles. These fines do not settle out raceway effluent for collection and contribute to pollution receiving waters. In this study, two experiments were conducted. Experiment 1 examined effects nine protein sour...
