The objective of this study was to initiate the constructing of correction factor in standardization of milk yield that needed in dairy cattle selection. Recording of pedegree, mating date, calving date, lactation period and milk yield obtained from Balai Besar Pembibitan Ternak Unggul (BBPTU) Sapi Perah Baturraden-Purwokerto were used as materials. Monthly record was obtained for milk yield. Milk yield in a lactation period was predicted by using modified Simplified Method. Modified Multiplicative Correction Factor was performed for calculating the length of lactation correction factor. Cows were grouped into Age Group I (KU-I) and Age Group II (KU-II), those were cows calving at <36 and ≥36 months old, respectively. Results showed that mean of milk yield of KU-I was smaller than that of KU-II. Correction factor for length of lactation for <305 days showed <1,00, whereas it for 305 days showed >1,00. In conclusion, length of lactation correction factor both in KU-I and KU-II indicated the same pattern along with the length of lactation in days. Keywords: correction factor, length of lactation, Simplified Method, Multiplicative Correction Factor, milk yield, dairy cattle
