The Comparison of Lactation Curve with Different Models in Mediterranean Water Buffalo Raised in Istanbul

This study was aimed to investigate biometry of lactation curve for Mediterranean water buffalo imported from Italy raised in private farm in Turkey. Total 72 head Italian water buffalo were used at first lactation and three calving seasons as animal material. Wood, Wilmink and Cobby and Le Du models were chosen in present study. The general average lactation period, total lactation milk yield average and average daily milk yield were found 234 days, 1607.4 kg and 6.86 kg, respectively. Determination coefficient was calculated for Wood, Wilmink and Cobby and Le Du models for summer calving season as 0.94, 0.92 and 0.93, respectively. Wood model was found the highest coefficient of determination in general. Moreover, persistency (S) and maximum milk yields (Ymax) for Wood model were calculated. These values were found as 5.89 and 9.76 for first lactation in general group, respectively.
