The invention discloses a protein biomarker as CHI3L1 protein, whose sequence number is <210>1; PSMB4 protein, whose sequence number is <210>2; and LGALS3BP protein, whose sequence number is <210>3. The above protein biomarkers are used in the diagnosis of early pregnancy in sheep. A method for diagnosing early pregnancy in sheep, characterized in that: the specific steps are as follows: 1. collecting blood samples: collecting sheep peripheral blood 14 days after breeding; 2. processing blood samples: separating serum or plasma for the blood samples of 1. step: 3., Kit detection: ELISA kits were used to detect the blood samples processed in step ② to detect the contents of CHI3L1 protein, PSMB4 protein and LGALS3BP protein. |
