| 中文摘要 |
| 由铬革渣提取蛋白质加工成的饲料蛋白粉,作为动物性蛋白质添加剂加入饲料,小白鼠喂养6周后增重率超过对照组,共喂7批,二代,剖检各器官未见异常。0.5kg的小鸡喂养27d后,1kg的中鸡喂养17d后增重率超过对照组,产蛋前期的产蛋率比对照组高40%,剖检各器官未见异常,肌肉、肝脏和蛋中未发现铬(ppm级)。 |
| 英文摘要 |
| The proteins extracted from scraps of chrome leather were mixed with bran and used as feed protein powder. The feeding test for mice showed that the animals grew faster by using the feed additive protein powder, compared with fishpowder after six weeks. No abnormal variations were observed in organs of the mice. The feeding test with the feed additive protein powder for chickens and middling hens showed that growth of the animals was accelerated in comparison with the group fed with fish-powder after 27 and 17 days respectively. The rate of layeggs in the initial stage was 40% higher than that of feeding fishpowder group. No abnormal variations were observed in organs, and chrome had not been detected out in muscle, liver and egg at ppm level. |
