tThe purpose of this study was to develop a new injection-molded intravaginal insert man-ufactured from ethylene-vinyl acetate containing progesterone for a 7-day insertion periodin cattle. The manufacturing process resulted in a reduction in the residual drug comparedto the silicone insert available while still maintaining biological performance.
