Quick answer:<\/strong> When buying feather meal, choose properly hydrolysed meal with 80\u201385% crude protein and pepsin digestibility of at least 75%, as raw keratin is indigestible. Ask for a certificate of analysis showing protein, moisture, fat and digestibility. Feather meal is used to raise protein in poultry, pig, fish and pet feed and as a slow-release nitrogen fertilizer.<\/p>\n

Why hydrolysis matters<\/h2>\n

Feathers are made of keratin, a tough protein animals cannot digest. Cooking feathers under steam pressure (hydrolysis) breaks down the keratin so it can be digested. Poorly processed meal has low digestibility and poor feeding value, so always ask for the pepsin digestibility result.<\/p>\n
