Characteristics of Holstein cows predisposed to ketosis during the post‐partum transition period

BACKGROUND: Ketosis is a common metabolic disorder during the post‐partum transition period of dairy cattle. How the method of reproduction, parturition time, and calf birth weight affect the occurrence of ketosis on dairy herds remains elusive. OBJECTIVES: This study investigated factors associated...

description BACKGROUND: Ketosis is a common metabolic disorder during the post‐partum transition period of dairy cattle. How the method of reproduction, parturition time, and calf birth weight affect the occurrence of ketosis on dairy herds remains elusive. OBJECTIVES: This study investigated factors associated with the severity of ketosis. METHODS: We divided 186 Holstein cows into three classifications based on the highest β‐hydroxybutyrate (BHBA) concentration during the post‐partum transition period, namely non‐ketosis (<1.2 mmol/L, n = 94), subclinical ketosis (1.2–2.9 mmol/L, n = 58), and clinical ketosis (≥3.0 mmol/L, n = 34). We evaluated characteristics of cows associated with the severity of ketosis. RESULTS: Ketosis was not associated with the method of reproduction, parturition time, pregnancy wastage, premature delivery, retained placenta, and type of calf. Cows calving in spring and especially summer were at higher risk of severe ketosis (p < 0.01). Cows with increased body condition score (BCS) at parturition, age, lactation number, and calving interval were more likely to develop severe ketosis (p < 0.05). Cows with clinical ketosis produced most milk (29.9 ± 1.0 kg) from days four to six, whereas cows without ketosis produced the least (21.3 ± 0.8 kg) (p < 0.001). Heavier calf birth weight resulted in high risk of severe ketosis (p < 0.01), due to increased milk yield during the early lactation. CONCLUSIONS: The severity of ketosis is associated with the calving season, BCS at parturition, age, lactation number, calving interval, milk yield in the early lactation period, and calf birth weight. Nonetheless, it was not associated with the method of reproduction, parturition time, pregnancy wastage, premature delivery, retained placenta, and type of calf. This study is the first to investigate the associations between ketosis and calf birth weight. Our findings could help predict cows at risk of ketosis and take precautions.
