| Abstract: | For developing immunoglobulin yolk powder products to prevent and treat the diarrheal piglets, and appling the advanced technology of egg yolk antibody to the husbandry and aquaculture, two types of compound immunoglobulin yolk powder were used to prevent and treat the diarrhea piglets which were challenged with ETEC, PEDV and TGEV.The creep feed added with 0.4% typeⅠimmunoglobulin yolk powder was provided to experimental piglets.There was no death after challenging the piglets with ETEC or virus, only 5 minor diarrhea in piglets in the early infection.As feeding continuing, the 5 piglets diarrhea quickly brought under control, conversely, the piglets in negative control group were totally dead.The immunoglobulin yolk powder type Ⅱ mixed with GNS at the rate of 1∶3 was used to cure the diarrhea piglets, 20 mL per piglet and 2 times a day.After curing for 3 days, the diarrhea was greatly improved, for 5 days the piglets diarrhea was basic recovery, and the survival rate could reach 84% to 88%.Dectected the infected of surviving piglets, compared to the drug treatment control group, prevention group had the lowest pathogen amounts, and the drug treatment control group had the most serious infected. |
