Division 7 Evaluation of the method
United Kingdom
The method has been tested in an intercomparison made at international level in 1990 using four different feed (mixed pig feed, broiler compound, protein concentrate, premixture). The results, after elimination of outliers, of mean and standard deviation are given in the tables in this point:
Means in g/kg
| n Number of participating laboratories. | ||||
| Reference material | Amino Acid | |||
|---|---|---|---|---|
| Threonine | Cyst(e)ine | Methionine | Lysine | |
| Mixed Pig Feed | 6,94 n = 15 | 3,01 n = 17 | 3,27 n = 17 | 9,55 n = 13 |
| Broiler Compound | 9,31 n = 16 | 3,92 n = 18 | 5,08 n = 18 | 13,93 n = 16 |
| Protein Concentrate | 22,32 n = 16 | 5,06 n = 17 | 12,01 n = 17 | 47,74 n = 15 |
| Premixture | 58,42 N = 16 | — | 90,21 n = 16 | 98,03 n = 16 |
