Effect of processing conditions of hydrolysed feather meals on the energy requirements and quality parameters [electronic resource].

Includes references.

Chicken feather meal represents a large potential source of protein for feed use. In Egypt, the volume of available dry feathers annually at processing plants has been estimated as 0.70 million tons (Ministry of Agriculture, 2001), which if made available for feed use, could do much to supply amino acids in poultry diets. The present study was undertaken to investigate the effect of processing conditions of feather meals such as, steam pressures (225,275,325 and 375 kPa), heating times (15,30,45 and 60 min), and two different treatments of feather (chopped and complete) on the energy requirements, and cost analysis of feather meals. Feather meals quality of the tested methods were also considered.
