Serum metabolites and body condition score associated with metritis, endometritis, ketosis, and mastitis in Holstein cows

Abstract: The objective of this work was to identify the serum metabolites and the body condition score (BCS) of Holstein cows associated with the occurrence of periparturient diseases, when under heat stress. Blood samples were collected from 181 cows one week after calving, and the BCS was recorded at calving. Cows with β-hydroxybutyrate (BHBA) concentration ≥ 0.8 mmol L-1 were 2.2 times more likely to develop metritis and 4.4 times more likely to develop clinical endometritis (CE). Cows with serum creatinine levels ≥ 2.0 mg dL-1 showed 2.2 and 4.5 greater risk (p ≤ 0.05) of suffering from metritis and CE, respectively, during the current lactation. The odds of metritis and CE occurrence were 2.7 and 4.6 times greater (p < 0.01) in cows with serum total protein (TP) ≥ 5.0 mg dL-1. Cows with serum glucose levels ≤ 70 mg dL-1 and non-esterified fatty acids (NEFAs) ≥ 0.5 had 9.4 and 8.8 times greater odds of developing clinical ketosis, respectively, than cows with lower glucose and NEFA blood levels. The strategic use of metabolic tests to monitor transition Holstein cows, aiming to prevent some postpartum diseases due to heat stress, should focus on blood BHBA, NEFAs, glucose, creatinine, and TP. Additionally, the BCS ≤ 3.2 should be avoided to prevent endometritis.
