28797

In this study, lifetime yield performances of Holstein Fresian cattle raised in Ceylanpınar Agriculture Farm were evaluated. Data for herd life, productive life, total calf numbers, total real milk yield, lactation length and daily milk yield were analyzed. Herd life varied between 1004 and 5471 days with an average of 2229.07±18.53 days (74.3 months). Average length of staying in production was determined to be 1236.10±13.87 days (41.2 months) ranging between 345 and 3929 days. Calf numbers produced lifetime varied between 1 and 8 with an average of 3.4±0.036. The average total real milk yield and lactation length were determined to be 16105.28±215.69 kg and 864.62±11.031 days (28.8 months), respectively. Daily milk yield varied between 9.57 and 46.50 kg with an of average 18.60±0.08 kg. Findings indicate that herd life is appropriate however; calf numbers per cow is low. The results of this study may provide valuable data for the farms in similar conditions.
