The control of the estrous cycle and ovulation in bovine breeders significantly improves the livestock cattle business. Controlled hormones release through loaded polymer matrices may control the estrous cycle and artificially induces ovulation. Hormones release from  biocompatible, biodegradable and injectable microbeads is an interesting alternative to the existing intravaginal devices. Some advantages of this technology are the possibility to perform massive artificial insemination at very low product and labor costs, fast and economic genetic improvement, delivery, feeding and vaccination programming and optimization. In addition, storage,  ransportation, application and dosage of microbeads are easier than using intravaginal devices. Moreover, aseptic conditions and the actions for introduction, retire and final deposition of intravaginal devices can be avoided.
