[Toxic effects of ammonium metavanadate on the growth and number of the offspring of Swiss albino mice].

The present research show, an statistical study of the effects of ammonium metavanadate (AMV) on size, weight and number of offsprings of 56 albino swiss mice (male and female) was carried out. These mice ingested AMV in concentration of 100 and 200 ppm "ad libitum" since birth, continuing throughout breasting until mating. The control group received water free from the metal. The statistical results, obtained by the Duncan and Tukey method, were the following: a significant drop in body size in 200 ppm concentration of AMV, and in tail size in a concentrations of 100 and 200 ppm. A significant increase was observed in the number of the offsprings on the groups treated with AMV on a concentration of 200 ppm with respect to the control group.
