The protein content of caster (Ricinus communis)
seed meal varies from 21 to 48% depending upon the extent of decertification
and oil extraction. It has an ideal amino acid profile with moderately high
cystine, methionine and isoleucine. But its antinutritional substances called
the ricin, ricinine and an allergen restricts its use in poultry even at low
levels of inclusion. Processing of caster meal by heating at 80 c temperature
in the presence of GN ammonia or an acid or alkali reduces the toxic content
substantially. Detoxified meal needs to be effectively corrected for lysine.
