The nutritional value of raw and autoclaved grain amaranth, its milling fractions (perisperm and bran), fat-free flour, and of popped amaranth was evaluated for growing chickens. The control diet, which was composed primarily of corn and soybean meal, contained 3.06 kcal apparent ME (AME)/g and 23.6% CP. Test diets contained about the same AME and CP levels, and the following levels of the test samples: whole grain amaranth flour, 61.46%; fat-free flour, 62.10%; perisperm, 49.50%; bran, 35.30%; and popped amaranth, 61.10%. Two groups of six unsexed broiler chicks each, 2-day old when received, were used per diet. Chickens fed diets containing autoclaved grain amaranth or its fractions over 17 or 18 days grew as well as those fed the control diet. Feeding of popped amaranth resulted in poorer performance. On a dry matter basis, AME values of raw grain amaranth flour, fat-free flour, perisperm, bran, and popped amaranth were found to be 3.21, 3.09, 3.68, 3.06, and 2.98 kcal/g, respectively. Respective AME values for the first four autoclaved samples were 3.04, 2.94, 3.10, and 3.17 kcal/g. Autoclaved grain amaranth and its perisperm fraction replaced corn in the diets of growing chickens with similar performance results.
对生的和经高压灭菌的籽粒苋、其制粉部分（胚乳和麸皮）、无脂面粉以及爆花籽粒苋进行了营养价值评估，以确定其对生长鸡的影响。对照日粮主要由玉米和豆粕组成，含有3.06千卡表观代谢能（AME）/克和23.6%的粗蛋白（CP）。试验日粮含有大致相同的AME和CP水平，以及以下水平的试验样品：全籽粒苋面粉，61.46%；无脂面粉，62.10%；胚乳，49.50%；麸皮，35.30%；爆花籽粒苋，61.10%。每种日粮使用两组，每组六只未区分性别的肉鸡雏鸡，接收时为2日龄。饲喂含经高压灭菌的籽粒苋或其组分的日粮超过17或18天的鸡，生长情况与饲喂对照日粮的鸡相同。饲喂爆花籽粒苋导致性能较差。以干物质为基础，发现生籽粒苋面粉、无脂面粉、胚乳、麸皮和爆花籽粒苋的AME值分别为3.21、3.09、3.68、3.06和2.98千卡/克。前四个经高压灭菌样品的相应AME值分别为3.04、2.94、3.10和3.17千卡/克。经高压灭菌的籽粒苋及其胚乳部分在生长鸡的日粮中替代玉米，性能结果相似。
