Haematological Studies on Stunting Syndrome in Broilers

Abstract

| Runting Stunting Syndrome (RSS) is a multifactorial disease with many names and faces that had caused considerable economic losses to poultry through reduced uniformity, reduced livability, decreased body weights, elevated feed conversions and many secondary diseases. The aim of current study was to evaluate the effect of stunting syndrome on haematology in chicks (n = 120) of different ages collected from nine (9) different farms. Grouping was done on the basis of age (G1 = 1-10 days, G2 = 11-20 days, G3 = 21-30 days, G4 = 31-40 days) including both stunted and normal chicks. Haematological results exhibited lower levels of haemoglobin (Hb), Total Erythrocyte Count (TEC) and Total Leucocyte Count (TLC) as compared to normal. Absolute Lymphocyte Count (ALC), absolute monocyte count (AMC) and Absolute Eosinophil Count was also found lower than normal. All these changes may interfere with normal digestive processes and normal body functioning resulting in poor weight gain and retarded growth or stunting of chicks.
