The object was to study on rats the effects of high molecular water-soluble polymer polycationite VPK-402 (polydimethyl diallylammonium chloride) under its use as a feed additive. Two trials were performed on growing rats with initial age 4 and 5 weeks, ascribed to 3 groups fed basic diet (BD, control) or BD supplemented with VPK at the dose 1 (group I) or 2 mg/kg body weight (group II) in the course of 63 days. The additive was fed with steam-treated wheaten once daily at morning. In the trial I (initial age 4 weeks), the average daily LWG was 128.9±4.7 (group I, P<0.05 vs control), 109.1±5.1 (group II), 107.8±4.8 g (control); in trial II (initial age 5 weeks): 128.9±4.7 (P<0.05 vs control), 109.1±5.1, 107.8±4.8 g respectively. Feeding polymer did not exert any negative influence on the skin, mucosa membranes and hair or behavior traits of rats. The data obtained suggest that polymer VPK may be recommended as a possible feed additive for productive animals.
