Abstract
In this work, effects of thiabfmdazole, chlorpro- mazine HOl and reserpine on milk yield and components, blood picture’, liver and Kidney functions were invest- before, during and after administration in lact- Priesian cows each of 3-5 years old and 420 Kg
body weight. Results can be summarized as follows: 1- Thiabendazole:
Thiabendazole was given orally to 26 lac¥tating I Friesian cows at a dose of 100 mg /Kg. Then faecal, milk,

ThitOendazole induc ed a signifj can t increase (P.( 0.05) i!t the milk yield. Chefflical analysis of milk samples reveal- dasignificant increase (pLo.05) in both fat and ash rcentages end a significant decrease (P~ 0.01) in both
