This review focuses on bull breeding behaviors and management strategies to improve reproductive efficiency. Breeding soundness evaluations are utilized classify a bull's physical ability sperm quality, yet roughly 20 % of bulls fail meet the minimum criteria. Furthermore, despite achieving criteria, few in multi-sire groups sire majority calves, indicating need for better understanding behavior that impact siring capacity, thus, Several factors influence libido such as age, breed, environmental conditions. Although service capacity tests have been used measure libido, standardization repeatability, along with variability age can be problematic. Management collection facilities largely pre-stimulation through behavioral cues quality quantity during collection, thus improving efficiency fewer collections increased doses harvested. In groups, social interactions, bull-to-female ratios, synchronization females, DNA testing determine parentage, techniques New research utilizing remote monitoring technology is being developed understand without constraints direct observation. may predict manage based dynamics, potentially detect lameness or injury capacity.

Criollo cattle, the descendants of animals brought by Iberian colonists to Americas, have been subject natural and human-mediated selection in novel tropical agroecological zones for centuries. Consequently, these breeds evolved distinct characteristics such as resistance diseases exceptional heat tolerance. In addition European taurine (
