What nutritional problem in cattle is characterized by swelling and lameness?

1. Acidosis

2. Founder

3. Milk fever

4. Grass tetany

The correct answer is: Founder

The nutritional problem characterized by swelling and lameness in cattle is founder, also known as laminitis. This condition occurs when there is inflammation of the sensitive laminae in the hoof, leading to severe pain and subsequent lameness. Founder is often linked to dietary issues, particularly excess consumption of carbohydrates, which can lead to an overload of sugars in the bloodstream and result in an inflammatory response. When cattle eat too much grain or carbohydrate-rich feeds, it can cause an increase in volatile fatty acids and lactic acid in the rumen. This shift may ultimately change the pH of the rumen, leading to an unhealthy digestive environment. As a result, the bacteria responsible for fermentation can proliferate, causing an imbalance in nutrients absorbed into the bloodstream, which contributes to the development of founder. Swelling may occur in the hooves due to the inflammation of the sensitive tissues within, causing discomfort and leading to lameness. It’s critical for cattle owners to manage the diet of their livestock carefully to prevent this serious condition, ensuring that grain is gradually introduced and balanced with fiber-rich forage to maintain a healthy digestive system. In contrast, acidosis primarily affects the rumen and does not typically result in swelling or lameness. Milk
