Despite the increase in milk yield in dairy cows, pregnancy rates have decreased by approximately 1% per
year in the last 25 years. The regular annual downward trend in conception rates has been steady in recent
years. Improvements in genetic tendencies for fertility may reverse this situation. For example, the calving
interval was shortened and the longevity was increased. Reproductive yield is a key factor in determining
profitability in dairy cows. Reproductive management is widely reviewed within the reproductive herd
health control program. New methods and technologies are being developed to assist reproductive
management. Breeding target for optimum yield in cows; to produce a live calf that gives birth at the right
time every year, with the right genetic value and without the problem of dystocia. Infertility is classified
as infectious, noninfectious (feeding, stress, genetic factors). Functional and infectious infertility is more
common in the cases of infertility. It is important to determine whether infertility is an individual or herd
problem. Although the fertility management of dairy cows differs from that of large and small farms,
similar procedures are performed as a result. Lack of regular registration system and inaccessibility of data
is an obstacle in small farms. Establishing a perfect monitoring system with the registration system in
fertility management, realizing a large number of data usage, feeding management, control of infectious
diseases, evidence based veterinary medicine, clinical and paraclinical examinations in a reliable and
accurate time to quickly determine the reproductive status , herd or individual problems, the use of
biotechnological methods such as genomic choice and selection, and fertility improvement programs such
as oestrus and ovulation synchronization, pre-synchronization and resynchronization should be
implemented. All these initiatives facilitate the implementation of the reproductive herd health
management program and produce satisfactory and economic results for veterinarians and farmers. In this
presentation titled infertility management in cows, striking sections of the reproductive herd health control
program, which has been implemented in dairy cattle enterprises in different regions of our country for
approximately 15 years, will be shared.
