"Two cows in lactation and two dry cows were used in two trials.In trials plastic particles of a cylindrical shape and specific gravity 1,25+0,05 g/cm3 were used Their sizes were 8/8, 11/11, 14/14, and 17/17mm. The total count of particle simultaneously applied one cow was 4x20 pieces. The plastic particlec were applied orally after feeding in the morning." . "RIV/00027014:_____/99:00008971" .
