Abstract

|
|
Hog cholera serum neutralizing antibody of piglets and sows were titrated by means of END SN method. The piglets of a variety of ages, precolostrally immunized with LOM living HC vaccine were subjected to the test. The sows were vaccinated with lapinized living HC vaccine after 25 days from the parturition. Throughout the studies the following results were obtained and summarised.
1. Hog cholera antibody titers of inbred sows immunized with lapinized living HC vaccine after 25 days from parturition were high except Hampshire group(Tab1e 2).
2. Sows, different stage of the pregnancy or the day of parturition, and of 3 way crossed, that were immunized with lapinized living HC vaccine have shown no significant difference on HC antibody titer(Table 2,3).
3. HC antibody titers of piglets, immunized with a single dose of LOM HC vaccine before feeding colostrum, were high in case of the younger group(1 week) compare to the older (7 week) (Table 4).
4. The piglets that were booster immunized with LOM HC vaccine at the age of 7 weeks have shown an inconsistent antibody titers (Table 5)
