Abstract An experiment was conducted with the objectives of determining the coefficient of ileal apparent digestibility (CIAD) and the coefficient of ileal standardized digestibility (CISD) of amino acids (AA) in housefly (HF) and black soldier fly (BSF) prepupae meal by growing pigs. Ten pigs fitted with a T-cannula in the distal ileum with an average initial body weight of 25.05 kg were housed individually in metabolism cages equipped with a feeder and a nipple drinker. The pigs were randomly assigned each to one of two diets formulated to contain 976.7 g/kg of HF or BSF as the sole source of nitrogen. A nitrogen-free (N-free) diet was also formulated to estimate the basal ileal endogenous loss (BEL) of AA. All experimental diets contained 2 g/kg titanium dioxide as an indigestible marker. The daily feed allowance was offered in three equal meals that were fed at 0830, 1400 and 1930 h. Each experimental period lasted for 7 days, the initial 4 d for diet acclimation, followed by 3 d for ileal digesta collection and the digesta samples were collected continuously for 12 h. The CIAD of all AA for HF and BSF are more than 0.726 and 0.641, respectively. The values for the CISD of all AA range from 0.870 to 1.608 and from 0.767 to 1.177 for HF and BSF, respectively. Moreover, the values for the CIAD of all AA in HF are greater (P

生长猪对家蝇和黑水虻预蛹的氨基酸消化率

摘要 为了测定家蝇 (HF) 和黑水虻 (BSF) 预蛹粉中氨基酸 (AA) 的回肠表观消化率 (CIAD) 系数和回肠标准化消化率 (CISD) 系数，进行了一项实验。成长中的猪。十头在回肠末端装有 T 型套管的猪，平均初始体重为 25.05 kg，被单独饲养在配备有喂食器和乳头饮水器的代谢笼中。这些猪被随机分配到两种饮食中的一种，这些饮食配方含有 976.7 g/kg HF 或 BSF 作为唯一的氮源。还制定了无氮 (N-free) 饮食以估计 AA 的基础回肠内源性损失 (BEL)。所有实验饮食都含有 2 g/kg 二氧化钛作为难消化标志物。在 0830、1400 和 1930 小时喂食三餐，提供每日饲料津贴。每个实验期持续 7 天，最初的 4 天用于饮食适应，然后是 3 天用于回肠食糜收集，并连续收集食糜样品 12 小时。HF 和 BSF 的所有 AA 的 CIAD 分别超过 0.726 和 0.641。所有 AA 的 CISD 值范围分别为 0.870 至 1.608 和 0.767 至 1.177（HF 和 BSF）。此外，HF 中所有 AA 的 CIAD 值更大（P 所有 AA 的 CISD 值范围分别为 0.870 至 1.608 和 0.767 至 1.177（HF 和 BSF）。此外，HF 中所有 AA 的 CIAD 值更大（P 所有 AA 的 CISD 值范围分别为 0.870 至 1.608 和 0.767 至 1.177（HF 和 BSF）。此外，HF 中所有 AA 的 CIAD 值更大（P
