**3. Conclusion**

Chemical messengers or pheromones have a direct developmental effect on hormone levels and behavior, and therefore, have a potential role in modulating animal behavior and reproduction management. The cattle pheromones acts as efficient means to decrease calving interval, post-partum anestrus period, optimized milk production, reducing anxiety and phobia, building a good maternal relationship, and helps in assisted reproductive, artificial insemination and BAS technologies. Pheromones have proved an economic and alternative role in estrus synchronization against hormonal treatment, and their potential to transform the animal behavior and management of reproduction has led to development and use of synthetic pheromones to manipulate reproduction and behavior, and once chemically synthesized and characterized, have got huge scope of application that is beneficial for livestock owners.
