Studies On Processing Technique For Expanding Blood Meal And Its Utilization

Expanding technique, one of the blood meal processing methods, was studied in the expeiiment by using P400(3 diy expander. The expanding blood meal was also analyzed and utilized for feeding the chicken. The results are as follows:1.P400(3 diy expander may process the expanding blood meal. Provided operating and mastering the processing technique exactly, the expanding blood meal can compass national A level standard.2.By microscope examination, the expanding blood meal has no perfect blood cell compared to the common blood meal wi~ich has perfect blood cell, therefor, the process of expanding can break the cell wall.3.The chickens?weight and digestibility had no olwious difference between the 2 percent fish meal add group and the 2 percent expanding blood meal group, therefore the expanding blood meal can be used to replace fish meal wiler definite percentage.4.The chickens?weight in the 2 percent expanding blood meal feed group vastly excels the 2 percent common blood meal feed group and the digestibility was better, therefore the expanding blood meal has better quality than the common blood meal.5.The weight arid digestibility of the chickens fed with 2 percent expanding blood meal group was the highest, and in the 5 percent add group was higher, so the best percentage of blood meal added is 2%, and then 5%.Candidate: YunFeng LiuMajor Veterinaiy Surgety MedicineSupemsor: HongBin Wang...
