Abstract :This research was conducted out to determine the knowledge, ideas and behaviors related to the managerial practices of calf’s 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 ten or more dairy cattle in Hendek district. Random sampling method was used to determine the sample size. The identified farms are divided into five class 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. In feeding management, farms with a capacity of 40 heads and less prefer grazing and supplementary feeding, while farms with a capacity of 40 heads and above prefer to feed in barns (P<0.05). While 74% of all farms have an annual average milk yield of less than 5000 liters, 26% yield more than 5000 liters (P<0.05). 15.6% of the farms produce less than five calves, 33.8% 6-10 calves, 28% 11-20 calves, and 22.5% have 20 or more calves (P<0.05). In 70.5% of the farms, calf losses occur within the first 30 days, followed by a decrease in deaths in the following weeks. While the answer to the question of separating the calves from their mothers after birth comes to the forefront in small-scale farms, the approach to separate them immediately or within the first 12 hours becomes prominent as the farm capacity increases (P<0.05). It was determined that approximately 77% of the farms did not have such an approach to determine the quality of the colostrum given to the calves, and it was determined that quality assessments were made as the farm capacity increased (P<0.05).Keywords : Buzağı, yaşama gücü, refah, kolostrum, sürü büyüklüğü, sürü yönetimi
