The rendering industry collects and safely processes approximately 25 million t of animal byproducts each year in the United States. Rendering plants process a variety of raw materials from food animal production, principally offal from slaughterhouses, but include whole animals that die on farms or in transit and other materials such as bone, feathers, and blood. By recycling these byproducts ...

Along the plant ingredients, rendered animal protein sources such as blood meal, meat and bone meal and poultry by-product meal have potential to be replaced by fishmeal in rainbow trout feed. Therefore, the main objective of the present study is to determine the effect of full replacement of fishmeal by poultry by-products meal (PBM) on fish performance, nutrient digestibility and also liver c...

This study was carried out to investigate the effect of replacing fish meal protein with fermented soybean meal (FSM) in diets on growth performance, feed utilization, morphological parameters, body composition, activities of antioxidant and digestive enzymes and also blood biochemistry of juvenile olive flounder (Paralichthys olivaceus). Five isonitrogenic and isolipidic diets were prepare...

 This study was carried out to investigate the apparent digestibility coefficients (ADCs) value of protein, amino acid and energy and body amino acid composition of rainbow trout fed solvent extracted soybean meal (SBM) and full-fat soybean meal (FFS) partly replacing fish meal (FM) in diets. Five iso nitrogenous (average 50.36% crude protein) and energetic (4294 kcal/kg total energy) diets wer...

Seabirds are attracted to fishing vessels by the discard of waste from fishing. While this waste provides an available food source, seabirds foraging near vessels are at risk of either being caught or struck by the fishing gear. Within New Zealand waters, there were 212 seabirds observed killed by trawlers during the 2006–07 fishing year. Birds feeding on fishing waste behind trawlers may be st...

The effects of amount and type of dietary fish proteins on plasma and liver cholesterol concentrations were evaluated in female rats. The isonitrogenous diets used contained 10 g cholesterol/kg and were carefully balanced for residual fat, cholesterol, Ca, Mg and P in the protein preparations. Cod meal, soya-bean protein or casein was incorporated into the diets as the only source of dietary pr...
