Native chicken rearing is gaining momentum among the poultry industry. But still there is a challenge of antibiotic residues in meat and more use of Biologicals, for which Herbo Chicken rearing might be the solution. Instead of use of Biologicals and antibiotics, native Chicken are fed with herbs like Justicia adhatoda, Osmium basilicum, Piper betle, Plectranthus ambonicus, Solanum trilobatum, Sesbania sp., Moringa oleifera, Delonix elata, Carica papaya, Azadirachta indica, Murraya koeniggi, Acalypha indica, Andrographis paniculata, and Achyranthus aspera based on the indigenous knowledge on ethnovetrinary medicine. This study was conducted to assess the difference in Haemlotological parameters of Herbo Chicken over The vaccinated Native Chicken flocks in Erode district of Tamil Nadu. Blood samples from 10 birds of 1.5 years of age each from regularly vaccinated native chicken flock and native chicken reared without vaccination and antibiotics in Sree Sakthi Native Chicken Farms, Erode were collected for this study. The haematological Parameters like Haemoglobin content, PCV, TEC and DLC were estimated using the standard protocol. The results obtained were analysed by conventional analysis in the form of averages and statistical analysis between both the groups were capmared by unpaired student‘t’ test. The results revealed that there was a statistically significant variation at 5% level (p<0.05) in Haemoglobin Content and PCV of Herbochicken with that of vaccinated Native Chickens. Statistically there was no significant (p>0.05) variation between Herbo Chicken and normal vaccinated flocks among other blood parameters like number of RBCs, Neutrophils, lymphocytes, Monocytes, Eosinophils and Basophils. This study found significantly increasing the Haemoglobin content and Packed Cell Volume in the herbo chicken and there is no reported disease outbreak in the farm as per farm records. A further study on factors responsible for disease resistance may be recommended.
