Product Description

EstroPlan is a prostaglandin F2-alpha analogue containing cloprostenol sodium. It is intramuscularly injected for luteolysis induction of dairy and beef cattle. This medication's luteolytic action is useful in manipulating estrous cycles to conform to specific management practices, treat prolonged luteal function-related conditions, and terminate pregnancies in mismating situations.

What is EstroPLAN?

EstroPLAN (cloprostenol sodium 250 mcg/mL) is an injection to induce luteolysis in beef and dairy cattle. The luteolytic action of estroPLAN injection can be utilized to manipulate the estrous cycle to better fit certain management practices, to terminate pregnancies resulting from mismatings, and to treat certain conditions associated with prolonged luteal function.

Why use EstroPLAN?

Features of EstroPlan:
  • Treats some prolonged luteal function-related conditions
  • Terminates pregnancies when mismating occurs
  • Manipulates the animal's estrous cycle to conform to specific management practices
  • Works to induce luteolysis in dairy and beef cattle

How does EstroPLAN work?

Corpus luteum morphological and functional regression (luteolysis) occurs in cattle. Non-pregnant, normal-cycling animals experience this effect on the corpus luteum lifespan, resulting in estrus between two and five days post-treatment. Animals with luteal cysts, mummified fetus, or pyometra (prolonged luteal function) will experience luteolysis and resulting condition resolution, then cyclicity return.
