NK Ingredients Pte Ltd is a world supplier of Cholesterol BP (Feed Grade) that is widely used as an additive to prawn feed.
Cholesterol BP (Feed Grade) is produced from woolgrease using multi-stage extraction and refining processes.
The material produced is minimum 91% cholesterol with minimum 97% total sterols.
Prawns are unable to produce the cholesterol that is required for the synthesis of molting hormones, steroid hormones and vitamin D. The lack of these sterols results in reduced growth and high mortality particularly of the larvae prawn.
Cholesterol BP (Feed Grade) must therefore be added to the prawn feed.
It is typically added to prawn feed at levels of 0.3 – 0.6%.
