Summary

The nultief&acy b3cterin containing Bordetella bronchiseptica (B.b), Pasteurella multccida (P.m.), Actinobacillus (Haernophilus) pleuxopneumoniae (A.p, or H.p.) and Escherichia coli (B. cdi) was goducel and ti-iei out. Two grou of sow administersi twice with 3 ml and 5 ml kectrin were wm, The geometric mean titer of the maternal antibody in 4-day-old suckling piglet against B.b. were higher in the 5 ml group (1 £,450-1 :Z(8) than in the 3 ml group (1:Z791-1:3,44. Lithe field trials, 47 sows were initially administered with 3 ml of the bacter-in and bx€terei with S ml after two web. The result indicated that 97.9% of the sows show&Ianti-B,b. titer over 1:1,280and93.6% of theiroffsprings alsoshow&Ithesameresult.
