The TME, true amino acid availability (TAAA), AME, and apparent amino acid availability (AAAA) were determined in full-fat seeds, meals, oils, and meal-oil mixtures of flax and canola using Single Comb White Leghorn roosters by the force feeding and total excreta collection assay. The metabolizable energy values were corrected to zero nitrogen balance to obtain AMEn and TMEn. The AMEn and TMEn contents of canola seed (4.46 and 4.56 kcal/g) were respectively higher (P < .05) than those of flax seed (3.75 and 3.75 kcal/g). Flax meal contains contents of AMEn (2.07 kcal/g) and TMEn (2.07 kcal/g) similar to those (1.98 and 2.09 kcal/g) of canola meal. There were no differences in AMEn and TMEn values between flax oil (8.10 and 8.28 kcal/g) and canola oil (8.25 and 8.46 kcal/g). No differences were observed among AME, AMEn, TME, and TMEn values within each test ingredient except canola meal: its TME value was higher (P < .05) than its AMEn value. The TAAA values were higher for full-fat seeds than for the meals and also higher for canola seed and meal than for flax seed and meal. The AAAA values, although lower than TAAA values, followed similar patterns as TAAA values. Both AAAA and TAAA values were higher when the ingredients were fed with a basal diet than when fed alone.
使用单冠白来航公鸡，通过强制喂食和总排泄物收集试验，测定了亚麻籽和油菜籽的全脂种子、粕、油以及粕 - 油混合物中的瘤胃微生物有效氨基酸（TME）、真可利用氨基酸（TAAA）、表观代谢能（AME）和表观可利用氨基酸（AAAA）。将代谢能值校正至零氮平衡以获得氮校正表观代谢能（AMEn）和氮校正真代谢能（TMEn）。油菜籽的 AMEn 和 TMEn 含量（分别为 4.46 和 4.56 千卡/克）分别高于（P < 0.05）亚麻籽的含量（3.75 和 3.75 千卡/克）。亚麻粕的 AMEn 含量（2.07 千卡/克）和 TMEn 含量（2.07 千卡/克）与油菜粕的含量（1.98 和 2.09 千卡/克）相似。亚麻油（8.10 和 8.28 千卡/克）和菜籽油（8.25 和 8.46 千卡/克）的 AMEn 和 TMEn 值没有差异。除油菜粕外，各测试成分内的 AME、AMEn、TME 和 TMEn 值之间没有差异：其 TME 值高于（P < 0.05）其 AMEn 值。全脂种子的 TAAA 值高于粕，油菜籽和粕的 TAAA 值也高于亚麻籽和粕。AAAA 值虽然低于 TAAA 值，但与 TAAA 值遵循相似模式。当将这些成分与基础日粮一起喂食时，AAAA 和 TAAA 值均高于单独喂食时。
