| Abstract: | This study aimed to compare the lactation performance of Holstein and Jersey. This study collected 896 DHI production records from a dairy farm in Jiangsu province from January to December 2020,and then multivariate variance method was used to analyze the differences between Jersey and Holstein lactation performances for different measured seasons, parities, lactation stages and calving seasons. The results showed that different measured seasons, parities, lactation stages and calving seasons had extremely significant effects on the lactation performance of Holstein and Jersey. The milk production of Holstein in different measured seasons, parities, lactation stages and calving seasons was significantly higher than that of Jersey, and the milk fat and protein rates of Jersey were significantly higher than that of Holstein (P<0.01). The SCS of Jersey was extremely significantly higher than that of Holstein in 1st parity and calved in spring (P<0.01). The results showed that both the Jersey and Holstein had their own advantages of lactation performances. |
