Abstract: 【Objective】 This study was aimed to systematically compare the lactation performance differences between Fleckvieh F1 and Montbéliarde F1 cows under the feeding conditions in Northern China. 【Method】 Dairy herd improvement (DHI) records from 2021 to 2024 were collected and obtained from a large-scale dairy farm in Yantai,Shandong province.The analysis focused on F1 cows from Chilean Simmental dams crossed with Fleckvieh and Montbéliarde sires.A mixed linear model was constructed using the SAS 9.4 software (Mixed procedure) to analyze the effects of breed,parity,measurement season,lactation stage and their interactions on lactation traits in Fleckvieh F1 and Montbéliarde F1 cows. 【Result】 Parity,season and lactation stage were found to significantly affect milk yield,milk fat percentage,milk protein percentage,and somatic cell score (SCS) in Fleckvieh F1 and Montbéliarde F1 cows (P<0.05).With the increase of parity,the milk yield,milk fat percentage and milk protein percentage were significantly increased across the first three parities in Fleckvieh F1 and Montbéliarde F1 cows (P<0.05).The milk yield and SCS were the highest in summer,while milk fat percentage and milk protein percentage were the highest in winter.With the increase of lactation days,the milk fat percentage,milk protein percentage and SCS initially declined and then increased in Fleckvieh F1 and Montbéliarde F1 cows.In the first lactation,Montbéliarde F1 cows exhibited significantly higher milk protein percentage than Fleckvieh F1 cows (P<0.05),with the difference becoming even more pronounced in the second lactation (P<0.01).Seasonal comparisons revealed that Montbéliarde F1 cows had significantly higher milk protein percentages only during winter (P<0.01).Regarding lactation stages,although Montbéliarde F1 cows demonstrated markedly higher milk protein percentage in early lactation (P<0.01),their values were significantly lower than those of Fleckvieh F1 cows in late lactation (P<0.05).Notably,the Montbéliarde F1 cows exhibited consistently lower SCS than the Fleckvieh F1 cows across all parities,seasons,and lactation stages.The results suggested that Montbéliarde F1 cows exhibited superior lactation performance and enhanced resistance to mastitis compared with Fleckvieh F1 cows. 【Conclusion】 Under the feeding conditions in Northern China,parity,season and lactation stage had varying effects on the lactation performance in Fleckvieh F1 and Montbéliarde F1 cows.The results provided valuable insights for breed improvement and production management decisions on dairy farms.
