ABSTRACT
This work describes various controlled tests that were conducted for the purpose of comparing the efficacy and effects of two antihelminthics (Dimethyl-Trichloro-Oxiethyl Phosphonate and Thiodiphenilamine) among the Nelore cattle raised on an extensive grazing in a pasture comprised of Panicum Maximum (colonião) grass. For such tests there was a selection of 21 heifers weighing between 128 and 227 kgs., which animals presented 200 or more strongylides eggs per gram of feces. Those heifers were sorted out at random in three groups of seven (7) animals each, one of which was left as a stand by group without any treatment at all. The two other groups were treated with Phenothiazine and Neguvon, respectively. At the end of the treatment, which lasted 25 days, four (4) animals of each group were sacrificed and a search for worms was performed in their gastrointestinal tracts. The efficacy of such treatments was noticed through the checking of worms in the feces. The efficiency of the antihelminthics was verified by means of hematological and biochemical testings of the serum and by weighing the animals. The results thus secured were analyzed statistically. 1 The antihelminthic drugs (Demithyl-Trichloro-Oxiethyl Phosphonate Neguvon and Thiodiphenilamine (Phenothiazine) tested during this research presented antihelminthical results with an evident superiority performed by t
