The present study, was undertaken to perform the effect of spirulina in reducing toxic signs, body weight and hematological parameters in arsenic toxicities in ducks. The experiment was designed and following methodology was adopted for performing the experiment. One hundred and seventy five, Xinding day old male ducklings were purchased from Kishoregonj Poultry Farm and fed with Aftab broiler starter feeds, Bangladesh. At fifteen day old the ducklings were randomly divided into 5 equal groups (n = 35) and were marked as group To, T1, T2, T3 and T4•
To- Ducklings were fed with recommended feed and drinking water ad. lib.
T1- Ducklings were fed with recommended feed and drinking water treated with arsenic trioxide@ 100 mg L•1.
T2- Ducklings were fed with recommended feed and drinking water treated with arsenic trioxide@ 100 mg L•1 plus spirulina@ 30 mg L•1.
T3- Ducklings were fed with recommended feed and drinking water treated with arsenic trioxide@ 100 mg L•1 plus spirulina@ 60 mg L•1.
T4- Ducklings were fed with recommended feed and drinking water treated with arsenic trioxide@ 100 mg L•1 plus spirulina@ 120 mg L•1.
Arsenic trioxide and spirulina at different dose rate were fed to different groups of ducklings with drinking water daily for 90 days. The parameters were taken fortnightly at day 15, 30, 45, 60, 75, 90 and 105. Fortnightly five birds were sacrificed from each group for studying following parameters: Toxic signs and body weight. Hematological parameters i.e. TEC, Hb, ESR and PCV.
Toxic signs and body weight: After feeding arsenic trioxide and spirulina all the control and treated birds were observed carefully for appearance of any toxic signs up to day 105. Body weight of the birds was measured at 15 days interval up to day 105 (15, 30, 45, 60,75,90 and 105). Hematological parameters: Total Erythrocyte Count (TEC), Hemoglobin content (Hb), Erythrocyte Sedimentation Rate (ESR) and Packed Cell Volume (PCV) were studied. For determination of hematological parameters blood samples were collected from five birds from each group fortnightly up to day 105 by from jugular vein i.e. on day 15, 30, 45, 60, 75, 90 and 105. Around 1.5 mL blood was collected in the sterile glass test tubes containing citrated anticoagulant. The hematological parameters were determined.
