Ketosis and metritis can flare with rising temperatures

Heat stress can add fuel to the flames when it comes to fresh cow risk factors for metritis. Ketosis is a fresh cow disease that is highly linked to metritis. Around 15 percent of early lactation, at-risk cows have subclinical ketosis in the first week after calving. In addition, cows with ketosis are 13.8 times more likely to develop a displaced abomasum and 1.7 times more likely to be challenged by metritis. Metritis incidence also climbs during periods of heat stress, costing producers between $304 and $354 in lost production and performance per case. FULL STORY »

Lameness in dry cows will likely mean ketosis in fresh cows

Ketosis is often a problem in fresh cows. A recently published study shows a strong link to lameness in dry cows. FULL STORY »
