The study was conducted to determine the stability of pellet in water and the amount
of zinc leaching from the pellet. The studied was carried out with three different types
of binder use in a pellet which incorporated with 100ppm of zinc amino acid. Treatment
1: CMC; Treatment 2: Carrageenan; Treatment 3: Algenate. Each type of pellets was
analyzed its composition. The stability measurement of pellet had been done by
immersing 5g of each pellet in 1L of tap water and the mass of pellet before and after
immersed in water had been taken. The leaching of zinc amino acid was tested by
taking the water sample and analyzed zinc concentration using ICP-MS and turbidity
using UV-VIS Spectrophotometer. The result showed there was no significant
difference between the pellets of each treatment for protein (p=0.376), lipid
(p=0.063), fiber (p=0.297), moisture (p=0.943) and ash (p=0.111) composition. For
stability measurement, there was significantly high in Treatment 3 (p=0.0001) after
45 minutes. There was no significant difference between each treatment for zinc
turbidity (p=0.087) and zinc concentration (p=0.646) in water samples after 45
minutes. The present study shows that alginate is the most stable binder in water for
zinc amino acid incorporated feed.
