Effect of feeding fenvalerate on haematobiochemicals in broilers.

A 42-days feeding trial was conducted to study the effect of fenvalerate (FEN) on certain haematobiochemicals in broiler chicks. Day-old straight run chicks (n=180) of same strain were randomly distributed to 5 experimental groups, each comprising 3 replicates of 12 chicks. Different levels of FEN at 0, 30, 60, 90 and 120 ppm were added in starter (0-21 d) and finisher (22-42 d) basal diets. At the end of starter and finisher phases, the blood samples were collected randomly from 2 birds per replicate viz. 6 birds per treatment, centrifuged for serum separation and analysed for certain haematobiochemicals. Alkaline phosphatase, aspartate aminotransferase, glucose and total protein increased significantly (P<0.01) in broilers fed diets containing 30 to 120 ppm FEN as compared to untreated basal diet during both the phases, while acid phosphatase, alanine aminotransferase and uric acid increased significantly (P<0.01) during starter phase but not during finisher phase. Total cholesterol was significantly higher (P<0.01) during the finisher phase. The study indicated that the fenvalerate when added in broiler diets caused disturbances in homeostasis of major blood biochemicals.
