I bought 500ml of Valbazen oral suspension. It contains 113.6mg/ml of albendazole. I read it somewhere about mixing equal parts of water and valbazen. So, if I put 0.5ml of valbazen, I should also mix it with 0.5ml of water? Also, I read that I should does them 20mg of albendazole per kg of body weight. So if my chicken is 1 pound I should give about 0.08ml of valbazen? 1kg= 2.20462 lbs. 20/2.20462= 9.072 9.072(x)=y x(weight in pounds)/ y(mg of albendazole) y/113.6=Z z(ml of valbazen) Z=0.08ml I really don't want to under dose them, since the worms will become resistant to it. Also, I don't want to overdose them, with an amount that can be detrimental to their health. What is the toxicity level of albendazole on chickens?
