Successful breeding just got easier with this cattle insert (progesterone) that improves the timing and efficiency of any breeding program you’re currently using. It’s indicated for synchronization of estrus in dairy yearlings and for synchronization of return to estrus in lactating dairy cattle. Synchronizes return to heat and tightens estrous synchronization so groups come into heat and can be bred in a narrow window. Induces fertile estrus, regardless of the stage of cycle. Eazi-Breed™ CIDR® results in: higher pregnancy rate (PR), because more cows and yearlings become pregnant at early breedings; easier and more accurate heat detection, improved value from semen and greater genetic gain, due to greater potential for successful artificial insemination (AI); more focused heat detection and easier AI breeding, since groups of cows and yearlings come into heat and can be bred at approximately the same time; yearlings freshening at a younger age; accurate breeding and calving dates of cows and yearlings; a more profitable dairy herd; more cows becoming pregnant in the first two cycles after the voluntary waiting period; and improved efficiencies in labor management. Each Eazi-Breed™ CIDR® contains 1.38 grams of progesterone in silicone molded over a nylon spine. Pkg. of 10 inserts. Applicator not included.
