摘　　要：以铬革渣为原料，经水解、脱铬等工艺制成皮革蛋白粉饲料，其营养成分分析及对猪、鸡的营养价值评定结果表明：ａ．该产品干物质和粗蛋白质含量分别为８９．０％和７６．９％，氨基酸分析结果表明该产品作为猪、鸡的饲料，第一限制性氨基酸为蛋氨酸；ｂ．选用大约克×大围子Ｆ１代生长育肥猪进行消化试验，测得粗蛋白质和总能的消化率分别为７８．１％和６９．９％，消化能为１１．５１ＭＪ／ｋｇ；ｃ．选用长沙黄成年公鸡进行代谢试验，测得总能的表观代谢率和真代谢率分别为６９．１％和８３．５％，ＡＭＥ为１１．３８ＭＪ／ｋｇ，ＴＭＥ为１３．１６ＭＪ／ｋｇ，蛋白质的沉积率为５７．１％。The chemical contents of leather protein meal made from tannery leather scrapswas analysed and its nutritive value for pigs and chickens was evaluated. The resultsshowed:a.The product contained 76.9%of crude protein and 89.0%of dry matter,thefirst litimting amino acid of the products was methionine(met)for pigs and chickens.b. Di- gestibility of crude protein(CP)and gross energy were 78.1%and 69.9%separately in thedigestive experiments with the F1 hogs of Large White x Daweizi by total collection method.c.The metablolic experiment with chickens showed that the CP retentivity was 56.54%,ap-parent metabolic rate and true metabolic rate of energy are 69.1%and 83.7%separqtely.
