Reproduction in fightingbull farm is conditioned by some factors that affect the stud and the cattle, where it emphasizes the stress derived of the using, the health, the environment and the food, just as the selection that have been subjected breeding. It means that different breeding techniques put into practice in other bovines don�t give good results and cause that bullfight farmer discard the use. The objective of this study is to obtain a estrus synchronization protocol valid for a bullfight farm with natural mount, to plan the births. This study was made in 20 bullfight cows with different ages and 1 eight years old stud used before, that formed one breeding lot in a bullfight farm of de centre zone. A estrus synchronization protocol in two steps was used. Firstly it was put progestin sponge in the vagina for 8 days and it was inyected intramuscular equine chorionic gonadotropine and F2á prostaglandine with cow, introducing then the synchronized animal in the enclosure with the stud, to the natural mount. The synchronization and the introduction to the enclosure were made gradual, with 4 cattle in each synchronization group. The results obtained were positive, with an increase of the fertility in the group of synchronized animals up to the 85%
