Comparative Potency Of Two Different Trivalent Vaccines Against Foot And Mouth Disease In Cattle Around The Area Of Ravi Campus Pattoki - 2016. - 66p.;

Foot and Mouth Disease is a highly contagious viral disease of all cloven footed animals.
The best control strategy of this disease is effective and in time vaccination. A successful
vaccination campaign depends on the serotype identification and specific vaccination against the
prevalent serotype of the virus. The present study was designed to evaluate comparative potency
of two anti-FMDV vaccines (UVAS-FMD, Deccivac Intervet) used in cattle around areas of
Lahore Pakistan. Blood samples were taken from vaccinated animals on day 0, 30, 60 and 90
post priming. Antibody titer was evaluated with different route of administration and various
adjuvant based vaccines. Four animal groups were made each containing 5 animals; in group 1
UVAS vaccine was used by Sub/ Cut route (gel based) at priming dose, followed by Intra
Muscular (oil) on 30th day. In group 2 UVAS vaccine was given I/M (oil) as priming dose and
booster (oil) I/M. In group 3 Deccivac (oil) vaccine was used I/M for priming and boosting. In
group 4 Deccivac (oil) vaccine was used as Sub/ Cut for priming and boosting. The results
revealed non-significant difference (p>0.05) among the four different groups administered with
FMDV vaccines when evaluated at day 30 and significant difference (p<0.05) at day 60 and 90
post vaccination. Analysis of variance showed significant difference (p<0.05) in antibodies
between groups and with in groups at day 60 and 90. Gel based vaccine gave quick antibody
response which later maintained with oil based booster dose. The difference in antibody titers
obtained in the present study was found non-significant (P>0.05) between the antibody titers of
FMD trivalent vaccine of UVAS and Deccivac at 90th day of inoculation. There was significant
difference (p<0.05) between the adjuvants of vaccine. Animals inoculated with priming dose of
gel based vaccine followed by oil based boosting showed significantly high anti FMD antibody
titer than animals inoculated with oil for both priming and boosting. There was significant
difference (p<0.05) between the groups vaccinated with various routes of administration. The
animals inoculated with priming dose through s/c followed by boosting dose i/m showed
significantly high anti FMD antibody titer at 90th day of inoculation compared with those
inoculated intramuscularly for both priming and boosting. The animals inoculated with oil based
vaccine for both priming and boosting through S/c showed marked significant decreased in anti
FMD antibody titer. The route of administration revealed significant difference (p<0.05) in
antibody response within groups and between groups at day 30, 60 and 90. In all three readings
the mean for sub/cut priming and IM boosting were found significantly high (p<0.05) as
compared to other routes. In conclusion it is recommend from the study that FMD vaccination
with sub/cut priming and booster dose with IM route.
