dc.description.abstractThe survival rate of calves in cattle farms provides information about calf mortality in the farm and is obtained by dividing the number of calves that live up to a certain period by the number of live-born calves. Factors such as breed, nutrition, climate, diseases, shelter, hygiene, type of birth, and gender affect the health and survival of newborn calves. In this study conducted on calf mortality in dairy cattle farms in the Tekirdag province, data collected through face-to-face surveys from 207 randomly selected dairy cattle farms were evaluated. The survey examined the structural characteristics of the farms and in-farm practices, focusing on calf care, feeding, and mortality. The total number of animals raised in the farms was found to be 15.9% for 0-5 heads, 26.6% for 6-10 heads, 31.4% for 11-20 heads, 18.4% for 21-30 heads, and 7.7% for 31 or more heads. It was determined that 71.5% of the farm owners were primary school graduates, 14% were secondary school graduates, 12.1% were high school graduates, and 2.4% were university graduates. The rate of septicemia vaccination for pregnant animals in the farms was 45.9%, and the rate of septicemia serum application to calves after birth was 69.1%. It was found that 33.8% of the farms had a calf mortality rate of 5%, with 48.3% of the deceased calves having a lifespan of 1-7 days, and 18.2% of the deceased calves' mothers also having lost other calves. Diarrhea was identified as a significant factor in calf mortality, and it can be suggested that increasing the use of prebiotics and probiotics, paying more attention to care, feeding, hygiene, and preventive health practices such as vaccinations, can reduce mortality rates. Another issue that can be considered as calf loss is the long service period. The extension of the service period, which is the time between giving birth and becoming pregnant again, results from various causes. Reducing the service period to optimal durations in farms depends on employing technical personnel, appropriate care and feeding practices, increasing heat detection applications and observation times, employing sufficient and qualified personnel, and implementing artificial insemination techniques. The results of this study suggest that enterprises involved in dairy cattle farming should take measures to reduce calf mortality rates and systematically monitor and control these rates through record keeping.
