Abstract :This research was conducted out to determine the knowledge, ideas and behaviors related to the managerial practices of calf survival in dairy cattle farms in Hendek district of Sakarya province, and to analyze the status of the existing farms. In the research, were identified farms which are registered to Turkvet and e-breeding system database having 10 or more dairy cattle in Hendek district. Random sampling method was used to determine the sample size. The identified farms are divided into 5 groups which are 10-20 heads, 21-30 heads, 31-40 heads, 41-50 heads and over 50 heads of cattle. In this context, after obtaining general data about the farms, questions related to the main topics about the care and management of calves such as colostrum use, feeding practices, health protection and housing were evaluated. Milk-fed to calves, marketed milk, marketed milk + waste milk, and marketed milk + milk replacer are given in three ways. Within the scope of the size of the farms, the difference between the source of the milk consumed during the milk feeding period was found to be significant (P<0.05). Until the first 30 days of age, in farms with a capacity of over 30 heads, approximately 8 liters of milk are given (P<0.05), while in small farms, sucking milk from the mother or giving less milk is preferred. Farms are sensitive about reaching the concentrate and rough feed of the calves, and they generally apply it from the first week. The concentrated feed used in calf feeding is approximately 70% in pellet form. The weaning age of the calves is 90 days in farms with 40 heads and below and after 90 and 120 days in farms over 40 heads (P<0.05). Age criterion taken into consideration at weaning was found to be more important than body weight and feed consumption (P<0.05). While the calves are housed mainly in groups (60%) in small-scale farms, individual pens (70%) stand out among the preferences due to the increase in capacity. Small-scale farms prefer metal, wood, and brick, and large-scale farms mainly plastic and metal materials for calf shelters (P<0.05). Eight weeks or more is preferred for keeping calves in individual pens (P<0.05).Keywords : Buzağı, yaşama gücü, refah, kolostrum, sürü büyüklüğü, sürü yönetimi
