| 摘 要： | 通过对膨化机的配备动力、螺杆及出料孔进行改造，开发了糊化机。糊化机生产的糊化淀粉尿素，达到了质量和安全要求。用糊化淀粉尿素饲喂奶牛效果明显，可以替代部分豆粕。对泌乳前期牛，混合精料中使用5%的糊化淀粉尿素为好；对泌乳中期牛，混合精料中以使用8%的糊化淀粉尿素为佳。

| Abstract: | Through remaking the power motor, screw extruder and discharge hole of the cooking extruder, the gelatinizing machine (extruder) was developed. By the gelatinizing machine, starea (gelatinized starch with urea) were produced which could reach the quality standards and safety requirements. The feeding effects of starea on dairy cows were significant and could substitute for parts of soybean meal. The better levels of starea in mixed concentrate for early and middle lactation phases were 5% and 8% respectively. |
