What problems may arise by manipulating the breeding season of a horse?

Manipulating the breeding season of a horse can lead to several problems, including disruptions in the natural reproductive cycle, which may affect fertility and conception rates. It can also cause health issues for both the mare and foal, as foals born outside of the optimal season may face environmental stressors that impact their growth and development. Additionally, such manipulation can lead to behavioral issues in mares due to hormonal imbalances, ultimately complicating management and training. Lastly, there may be economic implications if breeding and foaling do not align with market demand.
