One third to one half of each animal produced for meat, milk, eggs and fibre is not consumed by humans. These raw materials are subjected to rendering processes resulting in many useful products. Meat and bone meal, meat meal, poultry meal, hydrolysed feather meal, blood meal, fish meal and animal...

The effects of diet processing technology on digestibility, postprandial ammonia excretion rates and plasma concentration of ammonia, glucose and cholesterol (CHOL) were determined in the European sea bass. Four dietary treatments were compared: diet EO (extruded basal fish meal diet); diet PO...

Apparent protein digestibility (APD), apparent lipid digestibility (ALD) and true protein digestibility (TPD) coefficients of some plant and animal protein sources were estimated for fingerling rohu, mean weight 5.2-6.5 g. Plant protein ingredients were incorporated as the sole source of protein...

The effect of partially replacing fish meal with different soyabean meal (SBM) products in sea bass (L. calcarifer) diets on growth and apparent protein digestibility was examined. Five isonitrogenous and isoenergetic diets were formulated to contain 100% fish meal (control diet), 21.0%...

Research on different poultry byproduct meals (poultry byproduct meal with or without feathers or hydrolysed feather meal) over the past 20 years is reviewed. Information is given on the chemical composition (DM, CP, crude fat, ash and essential amino acids) of the various meals as well as the...
