Özet: This investigation was conducted to determine lactation curve parameters in Anatolian buffaloes by polynomial model (AS). As a research material, 1092 test days milk yield records belonging to 190 head Anatolian buffaloes were used. For this purpose, the data of 3 and 4 year old Anatolian buffaloes that started lactation in year 2017 was used. The test day data were grouped according to age groups. Lactation curve parameters had established by via STATISTICA program. Lactation curve parameters (a, b, c, d and g) were determined as 4.82±0.809, 1.61±0.052, 0.71±0.249, 7.31±1.811 and 2.93±0.059, respectively, for three year old. The coefficient of determination and mean square error were estimated 98.17 and 0.032, respectively for three year old. Lactation curve parameters (a, b, c, d and g) were determined as 5.31±0.647, 1.07±0.049, 0.62±0.413, 6.11±0.988 and 2.15±1.740, respectively, for four year old. The coefficient of determination and mean square error were estimated 99.46 and 0.013, respectively for four year old.
