Abstract
This work aim to clear the effect of LD50 values of varied anticoagulants on the body weight reduction, day to death and appetency percentage for male, female and juvenile of the albino Norway rat, R. norvegicus under laboratory conditions. The gained results could be concluded as next: The LD50 values of the treated male, female and juvenile of R. norvegicus with each of Bromadiolone, Difenacoum and Chlorophacinone were; (0.81, 0.91 and 0.78 mg/kg b.w.), (1.40, 1.54 and 1.27 mg/kg b.w.) and (6.02, 6.13 and 5.92 mg/kg b.w.), respectively. These figures proved that adult male was more susceptible than female for the whole tested anticoagulants, meanwhile juvenile was more susceptible than adult. The body weight reduction percentages for male, female and juvenile were; (13.9, 10.7 and 14.3%), (21.8, 13.7 and 13.5%) and (10.2, 10.9 and 18.2%) for Bromadiolone, Difenacoum and Chlorophacinone, respectively. In addition, mean day to death of the treated individuals with LD50 values of Bromadiolone, Difenacoum and Chlorophacinone were (6.0, 6.0 and 4.6 days), (4.0, 6.0 and 4 day) and (6.8, 6.6 and 4.5 day) respectively. In other words, Difenacoum was the most effective one against the experimental individuals followed by Bromadiolone and Chlorophacinone. Also, the results proved that the adult (male and female) and juvenile which treated with the tested anticoagulants lost their appetite for the introduced plain food after the treatment gradually. As well as, the data cleared that there is a positive link between appetency percentage and the body weight reduction for adult (male and female) and juvenile both of R. norvegicus.
