The statistics, data processing were allocated according to a completely on some of energy rich ingredients such as; corn, rice bran, wheat bran ... and mineral rich materials such as: dicanxiphotphate. The sample collected for 14 years from 2006 to 2019, Chemical composition quantified are: dry matter, crude protein, crude fat, crude fiber, neutral fiber, acid fiber, crude ash, calcium, phosphorus and starch.
Results compared to results in the book “Composition and nutritive value of animal feeds in Vietnam” " was published in 1995 and reprinted in 2001 by the National Institute of Animal Hasbandry is now National Institute of Animal Science, the results are less different that only enriching and diversifying data. The difference only raises a problem that of the plant is change of some chemical composition due to new varieties.
Adding some new materials, add new composition: 24 wheat samples, 72 extracted rice bran samples, 13 dried rice bran samples, 14 fresh rice bran samples, 465 dicanxiphotphate samples, starch component, neutral detergent fibre (NDF ) component, acid detergent fibre (ADF) component,
