Saya setuju dgn pendapat oom TSA, bahwa gangguan fungsi hati dapat mengakibatkan skin koi agak kekuningan... ini cuplikan artikel yg mungkin dapat sedikit memberikan pencerahan :
Why Silk powder :
Silk is made of protein called Fibroin. This protein contains such a lot of absolutely essential amino acid for living creatures as Aranin. Glysine and Tyrocine. Especially, it contains 8 times as much Glysine as milk does and 6 times as much as an egg does. These amino acids improve liver fuction and detoxification and lower cholestrol in blood.
When liver function declines, koi’s skin gets yellowish. Paradoxically speaking, improvement of liver function guarantees pure white skin. Silk powder makes koi’s skin pure white. This is a new discovery in Nishikigoi world.
