abstract
Day old 80 cockerels after acclimatization for a period of one week were randomly divided into four equal groups comprising 20 birds in each. During experimental study, birds of fenvalerate treated group showed clinical signs of paralysis, tremors and convulsion observed which indicated neurotoxic effect of fenvalerate after second week of experiment and at 6^th week of age birds showed milder clinical signs. Significant reduction in body weight, weight gain, feed consumption and FCR were observed in fenvalerate treated group throughout experimental period but numerical improvement due to the effect of Ashwagandha. At the end of 5^th and 6^th week significant decrease (P≤0.05) in Hb (hemoglobin), TEC (Total erythrocyte count), PCV (Packed cell volume), TLC(Total Leucocytes Counts) and lymphocyte count was observed in fenvalerate group but progressive improvement seen in Ashwagandha treated group. It was concluded that supplementation of Ashwagandha root powder through feed may reduce the severity of fenvalerate toxicity in cockerels.
