The 6 cannulated gilts, with initial body weight (BW) 34.8 ± 0.7 kg, fitted with ileal T-cannula in terminal ileum were used for estimation apparent (AID) and standardized (SID) ileal digestibility of nitrogen (N) and amino acids (AA) in wheat germs. Animals were fed twice a day with tested diet in two equal doses at daily rate of 75 - 80 g.kg - 0.75. Water was offered ad libitum. The test feed was the only source of protein in the diet. After the 14 d postoperative period followed 6 d

Chromium oxide (Cr2O3) was used as an indigestible marker in amount of 0.3 % per kg of diet. We calculat(Cr2O3) was used as an indigestible marker in amount of 0.3 % per kg of diet. We calculat(Cr2O3) was used as an indigestible marker in amount of 0.3 % per kg of diet. We calculat(Cr2O3) was used as an indigestible marker in amount of 0.3 % per kg of diet. We calculated AID and SID of AA and N using analytic estimated values of N, Cr2O3, and AA. The SID of AA in wheat germs ranged from 86.6 % (tyrosine) to 97.6 % (proline) (P < 0.05).
