本研究通过对两种类型饲料的比较，发现同传统的干烤鼠料相比，膨化过程在对饲料做熟化、膨松处理以提高适口性的同时，还兼有一定的灭菌作用；此外，膨化时短时间高温高压对饲料中不稳定养分—维生素类破坏作用弱。膨化料比干烤鼠料硬、不易破碎，浪费少。用膨化料饲喂生长、繁殖实验小鼠，也获得了同干烤鼠料相同的饲喂效果。因此认为膨化料不仅适用于实验犬、猴，也是一种较为理想的实验小鼠饲料
In this study, we compared the two types of feed and found that, compared with the traditional dry roasted rat feed, the puffing process also has certain sterilization effect while making the feed mature and bulky to improve the palatability; besides, , When puffing a short time high temperature and high pressure on the feed unstable nutrients - vitamins weakly damaged. Expanded material than dry roasted rat hard, not broken, less waste. Extruded feed feeding growth and reproduction of experimental mice, but also get the same feed with the dry grilled feed effect. So that puffed material is not only suitable for experimental dogs, monkeys, but also a more ideal experimental mouse feed
