Minimizing Subclinical Metabolic Diseases


Abstract

Subclinical ketosis is a common disease in lactating dairy cows with a lactational incidence rate above 40% in many herds. This condition is associated with increased clinical disease risk, reduced milk production, and impaired reproductive performance. On a herd basis, subclinical ketosis is much more costly than clinical ketosis. Prevention is achieved largely through effective dry cow programs that encompass both good nutrition and excellent cow management. However, certain additives are helpful in reducing subclinical ketosis. These include propylene …

Progress in the Understanding of Hemorrhagic Bowel Syndrome


Abstract

Hemorrhagic bowel syndrome (HBS), a deadly digestive tract disease, has been reported with increasing frequency in adult dairy cows. Cattle affected with HBS usually die within 12 to 36 hours after the onset of clinical disease. Cattle present with acute enteritis and concurrent dehydration and shock, with or without signs of abdominal pain. The case fatality rate is 85 to 100%. Pathologic examination of affected animals reveals severe hemorrhagic enteritis with intraluminal hemorrhage or blood clots. Both Clostridium perfringens…

Inflammation and Transition Cow Disorders

 

Introduction

The multitude of disorders that dairy cows face during the transition to lactation is a perennial source of concern for dairy producers, nutritionists, and veterinarians. Total disease incidence in the several weeks after parturition accounts for a substantial proportion of all morbidity on many dairies (Ingvartsen, 2006), with particularly high rates of mastitis, metritis, milk fever, displaced abomasum, ketosis, and fatty liver, among other problems. Not surprisingly, these issues have been the focus of much research in recent …

Nutrition and Claw Health


Abstract

The health and function of the bovine claw is dependent upon sound nutrition and feeding practices. In this context, the avoidance of rumen acidosis, which is considered to be the predominant predisposing cause of laminitis, is believed to be of paramount importance. Acidosis in its acute form is a life-threatening disease. In its subclinical form, acidosis contributes to decreased performance, poor body condition, and lameness most often due to laminitis and related claw disorders. In addition to being the …

Prevention of Displaced Abomasum


Abstract

Because of intake depression prior to calving and slow intake ascent postcalving, the transition period is the major risk period for abomasal displacements. Feeding and management practices that prevent other calving-related disorders reduce the risk of abomasal displacements. Cows that have excess body condition at calving are at increased risk of ketosis and abomasal displacements. Both excessive and minimal feeding of concentrates precalving may increase the risk of abomasal displacements. Feed bunk management is an important risk factor for …
