Abstract
The study was designed to evaluate the effect of breed and sex on
haematological and serum biochemical profile of White Pekin and Indigenous
ducks and to understand the variation in the egg quality traits and cholesterol
content in White Pekin and Indigenous duck eggs of Tamil Nadu.Eighty number of ducks comprising 20 male and 20 female each in White
Pekin and Indigenous ducks of Tamil Nadu were reared under standard
managemental conditions. Once in every 4 weeks, blood was collected from these
ducks individually. Three milliliters of blood was collected from each group of 20
White Pekin ducks and 20 Indigenous ducks of Tamil Nadu. 1 ml of blood was
taken in EDTA vaccutainer tube and 2 ml of blood was kept undisturbed for two
hours for separation of serum. 1 ml of blood was later used to estimate the
Haemoglobin concentration, Packed Cell Volume (PCV), Total Erythrocyte Count
(TEC) and Total Leucocyte Count (TLC) and Differential Count (DC). The
biochemical parameters such as Total Serum Protein, Serum Globulin, Serum
Triglyceride, Serum Cholesterol and Serum Calcium were estimated by using a
Biosystem Auto Analyser. External egg quality traits like Egg Weight, Shape
Index, Surface Area and Aircell Depth were assessed and also the Internal egg
quality traits such as Albumen Index, Haugh Unit, Yolk Index and Yolk Colour
were studied. Cholesterol content in egg yolk was also estimated.
Among breeds, Indigenous ducks had significantly higher (P<0.01) Total
Erythrocyte Count (TEC), Haemoglobin (Hb), Packed Cell Volume (PCV) and
Heterophil Count while White Pekin ducks had higher (P<0.01) Total Leucocyte
Count (TLC), Mean Corpuscular Haemoglobin (MCH) and (P<0.05) Monocyte
Count. Breed had no significant effect on Mean Corpuscular Volume (MCV) and
Mean Corpuscular Haemoglobin Concentration (MCHC) in White Pekin and
Indigenous ducks of Tamil Nadu. Serum biochemical profile such as Total Serum
Protein, Albumin and Globulin was significantly (P<0.01) higher in White Pekin
ducks while Serum Triglyceride was significantly (P<0.01) higher in Indigenous
ducks of Tamil Nadu. External egg quality traits like Egg weight and Surface Area
in White Pekin ducks were higher (P<0.01) whereas most of the Internal egg
quality traits like Albumen Index, Haugh Unit, Yolk Index and Shell thickness
were significantly (P<0.01) higher in Indigenous ducks of Tamil Nadu. Egg yolk
Cholesterol content was significantly (P<0.01) higher in Indigenous ducks of
Tamil Nadu.
Sex did not influence the Total Erythrocyte Count (TEC), Total Leucocyte
Count (TLC), Haemoglobin (Hb), Packed Cell Volume (PCV), Mean Corpuscular
Haemoglobin (MCH), Mean Corpuscular Volume (MCV) and Mean Corpuscular
Haemoglobin Concentration (MCHC) values while the Serum Biochemical
profiles such as Total Serum Protein, Globulin, Triglyceride and Calcium
(P<0.01) were higher in White Pekin female ducks whereas Serum cholesterol
level (P<0.01) was higher in females of White Pekin and Indigenous ducks of
TamilNadu.
