Heamatological Indices of Sahel and West African Dwarf Goats Vaccinated Against Pestes despetits Ruminants (PPR) Adua

This project determined the effect of Peste des petit ruminants (PPR) vaccine on the haematological indices of two breeds of goats (Sahel and West African Dwarf) and evaluated the effects of breed and sex on the haematological parameters. Haematological indices of the initial sample (comprising ten Sahel and ten WAD breeds) were evaluated prior to vaccination. Thirteen of the twenty goats were vaccinated against PPR, while seven (four WAD and three Sahel) were not vaccinated thus serving as control. Fourteen days after the vaccination, the haematological parameters of the vaccinated and unvaccinated goats were again evaluated. The data were analyzed using unequal replication module in GENSTAT. The findings revealed variation in some of the parameters studied. PPR Vaccine had no significant (P<0.05) influence on neutrophil and lymphocyte. However, in the vaccinated goats, there was an increase in the lymphocyte numerical values. The increased values indicate different levels of immune status of goats. Sex had significant influence (P<0.05) on Haemoglobin (HB), Red Blood Cell (RBC) and Packed Cell Volume (PCV). While their values were lower in the male compared to the female in Sahel breed, the contrast was the case for WAD goats. The study revealed that PPR vaccination led to increased lymphocyte count, which will raise the immune status and enhance greater resistance of the goats to PPR challenges.
