Chemical composition analysis results on some of protein rich meterials for animal feed production from 2006 to 2020
Reference database for researchers on nutrition, animal feed rations and teaching, supplementing the chemical composition table when re-publishing the book; ‘Composition and nutritional value of animal and poultry feed in Vietnam”; The data is statistically and processed for a period of 15 years from 2006 to 2020 at the Department of animal feed and products analysis. Analytical methods are livestock industry standards (TCN), Vietnamese standards (TCVN), are prescribed for chemical composition determination including dry matter, moisture, crude protein, real protein, crude fat, fiber raw materials, raw ash, calcium, phosphorus, NaCl, NH3, urea and sand... in materials and animal feed. The results obtained from 5 sources of high-protein materials show that: Fishmeal: the period from 2006 to 2020, the chemical composition had an increase; dry matter was 90.68% compared 83.49%; crude protein was 64.85% compared 55.79%; crude fat was 9.92% compared 5.58% and decreased: crude ash was 21.60% compared 31.67%; calcium was 5.96% compared 6.92% published in 2001. Soybean meal: crude protein, crude ash, phosphorus and crude fiber did not have a significant change inf the mean value the 2001 publication compared with the period from 2006 to 2020, only the crude fat and calcium are more diffrent. Dried rapeseed: The small number of samples (published in 2001, 02 samples; 05 samples in the period 2006 to 2020), so it did not reflect the true value. Dried peanut: Crude protein and crude fat parameters have the difference of the mean value between the published in 2001 and the period 2006 to 2020 due to the limited number of samples, therefore, the data are not representative. Meat and bone meal: There was no difference from the 2001 compared with the period from 2006 to 2020 was dry matter; the crude protein, crude fat, crude ash, calcium and phosphorus were present insignificant difference of the publication in 2001 compared to the period 2006 to 2020 may be due to the limited number of samples, moreover that is also reflected, through standard deviation is high from 3.01 to 8.74 of the period 2006 to 2020 and from 3.67 to 6.51 of the published 2001. The difference in some chemical components of materials is fishmeal, only raised one problem is that modern and advanced fishing and processing technology has increased the quality of materials for animal feed production.
