| 摘 要： | 饲用血粉的生产从采用干燥工艺，发酵工艺，到采用喷雾干燥工艺，都存在产品的可消化率偏低的问题，并涉及诸如生产环境和耗能过大等问题，本校采用专门研制的连续膨化设备对含有一定水分的碎血块进行连续瞬时加工，经进一步粉碎后，制成了新型饲用血粉－膨化血粉，其体外消化率达９７．６％。用含有膨胀化血粉的配合饲料喂养淡水鱼类的平均饲料系数为１．７９。利用膨化血粉和喷雾血粉对ＡＡ肉鸡进行对比喂养试验表明，两组的平均饲

| Abstract: | A technological process of extrusion cooking for animal blood was studied instead of such common processing methods as drum drying, spray drying and fermentation. In general, animal blood meal processed by the common methods has the disadvantages of low digestibility, high cost for processing and environmental pollution. If animal blood cakes containing 17% of moisture were processed by the extruder of continuous type, the digestibility of animal blood meal was more than 97% in vitro. The experimental results of feeding test showed that when the blood meal was partly mixed with fish meal as an ingredient of fish diet, the conversion factor was 1. 79 in average. Using extruded blood meal and spray dried blood meal for the rearing tests on AA-chicken, the conversion factor was 2. 10 and 2. 24, the survival rate 98. 33% and 93. 33%, and the weight of growth 1893. 85g and 1805. 79 g, respectively. |
