There are actually two main kinds of feeds: commercial pelleted feed which are mostly used and home-made fresh feed.
The commercial pelleted feed means the feed which is dried and pelleted by industrial processing lines. The feed has been studied and rationally mixed to ensure the nutrition for each type of species. With the feed conversation rate (FCR) of 1.4 - 1.6, the use of pellets saves the environment.
Home-made fresh feed is made by available local materials (such as rice, fishmeal, soy bean, cassava…) which are mixed and processed. These materials are finely ground, mixed together, cooked and cooled, and then made into small handfuls or pressed into pellets to feed fish.
The pellets for Pangasius need to meet requirements on the quality and veterinary hygiene, in compliance with the Sector Standard No. 28 TCN 188:2004. The MARD is responsible for the registration for quality, inspection of hygiene conditions at feed mills and of quality of feeds.
Use raw materials from nature and resonably mix to ensurace protein content from 15 - 20%. Some method of mixing feed for reference.
