Common Disorders
Displaced Abomasum
Bloat
Milk Fever

6. Bloat Description Symptoms Build up of gas in the rumen
Hunger Pains
Principles of Agricultural Science – Animal
Unit 5 – Lesson 5.4 Nutritional Disorders
Bloat
Description
Build up of gas in the rumen
Symptoms
Distended left abdomen
Pain, discomfort, and bellowing
Death can occur within 15 minutes
Curriculum for Agricultural Science Education Copyright 2015

7. Bloat Causes Effects on Production Death can reduce the herd
Hunger Pains
Principles of Agricultural Science – Animal
Unit 5 – Lesson 5.4 Nutritional Disorders
Bloat
Causes
Occurs when eructation of gas is prevented
Stable foam develops on top of liquid in rumen, which is caused by legumes such as clover and alfalfa
Effects on Production
Death can reduce the herd
Decrease milk production and quality

Unit 5 – Lesson 5.4 Nutritional Disorders
Bloat
Prevention Measures
Avoid using high risk pastures
High clover pastures should not be used
Do not allow cattle to graze pastures when wet
Administer anti-foaming agent daily (baking soda works)

9. Milk Fever (Hypocalcaemia)
Hunger Pains
Principles of Agricultural Science – Animal
Unit 5 – Lesson 5.4 Nutritional Disorders
Milk Fever (Hypocalcaemia)
Disorder that occurs close to calving, metabolic disease caused by low blood calcium levels
Symptoms
Dry muzzle
Starring eyes
Cold legs
Cold ears
Constipation
Drowsiness
Weak and faster heart beat
Body temperature falls below normal
Curriculum for Agricultural Science Education Copyright 2015

10. Milk Fever (Hypocalcaemia)
Hunger Pains
Principles of Agricultural Science – Animal
Unit 5 – Lesson 5.4 Nutritional Disorders
Milk Fever (Hypocalcaemia)
Causes
About 80% of cases occur near calving as colostrum drains the calcium from the blood
Age is important, older cows are more susceptible
Effects on Production
Decreases milk production

11. Milk Fever (Hypocalcaemia)
Hunger Pains
Principles of Agricultural Science – Animal
Unit 5 – Lesson 5.4 Nutritional Disorders
Milk Fever (Hypocalcaemia)
Prevention Measures
Management of the diet
Cows should be kept on low calcium diet while dry
Jersey cattle are more susceptible
Calcium Borogluconate injections
