This is an article concerning the research into the fishculture with the pellet feed made from fermented pig blood. The article discribes materials and method of the experiment, and shows how to compound the materials for pig blood fermentation and how to analyse the nutrition of this new feed. By using such a pellet feed, the fish yield has been increased 27.93%. The essential amino acid contained in pig blood has much more increased than that before its fermentation, and that the protein content of pig blood is near or equal to that of animal meats. 相似文献
