Overview of Common Cattle Health Issues
Most Common Cattle Health Problems by Frequency
Understanding the prevalence and impact of various cattle health issues enables farmers to prioritize their prevention efforts and allocate resources effectively. The most common problems typically involve the respiratory and digestive systems, which are often interconnected with management practices, environmental factors, and nutritional programs.
Respiratory Diseases
Respiratory diseases represent the leading cause of morbidity and mortality in cattle operations worldwide. These conditions can significantly impact growth rates, feed efficiency, and overall productivity.
Bovine Respiratory Disease (BRD)
| Disease | Primary Symptoms | Secondary Signs | Risk Factors |
|---|---|---|---|
| Pneumonia | Coughing, nasal discharge, fever | Reduced appetite, labored breathing | Stress, overcrowding, poor ventilation |
| IBR (Infectious Bovine Rhinotracheitis) | Red, inflamed nose, clear discharge | Conjunctivitis, mouth lesions | New cattle introductions, stress |
| PI3 (Parainfluenza-3) | Mild cough, slight fever | Secondary bacterial infections | Young calves, immune suppression |
| BRSV (Bovine Respiratory Syncytial Virus) | Severe coughing, rapid breathing | Open-mouth breathing, weakness | Fall/winter seasons, confined spaces |
Early Detection Signs for Respiratory Issues
- Changes in breathing patterns or rates
- Persistent coughing, especially during feeding
- Nasal discharge (clear to purulent)
- Elevated body temperature (above 103°F/39.4°C)
- Reduced feed intake and water consumption
- Drooping ears and head positioning
- Isolation from the herd
Digestive Disorders
Digestive health directly impacts nutrient absorption, growth rates, and overall cattle performance. Proper nutrition management and monitoring are essential for preventing these issues.
Common Digestive Problems
| Condition | Cause | Symptoms | Prevention |
|---|---|---|---|
| Acidosis | Excessive grain intake, sudden diet changes | Diarrhea, dehydration, reduced rumination | Gradual diet transitions, proper roughage ratios |
| Bloat | Gas accumulation, legume consumption | Distended left side, difficulty breathing | Gradual pasture introduction, anti-bloat agents |
| Displaced Abomasum | High-concentrate diets, stress factors | Reduced appetite, ketosis, decreased milk | Balanced nutrition, stress management |
| Scours (Diarrhea) | Bacterial, viral, or nutritional causes | Watery feces, dehydration, weakness | Clean water, proper colostrum, vaccination |
Critical Warning Signs Requiring Immediate Attention
Severe digestive emergencies include:
- Acute bloat with visible left-side distension
- Complete loss of appetite lasting more than 24 hours
- Profuse, watery diarrhea with blood or mucus
- Signs of severe dehydration (sunken eyes, skin tenting)
- Grinding teeth or signs of abdominal pain
Reproductive Health Issues
Reproductive efficiency directly impacts the profitability of cattle operations. Understanding and preventing reproductive disorders is essential for maintaining breeding success rates.
Major Reproductive Disorders
Retained Placenta
Causes: Difficult births, nutritional deficiencies, infections
Prevention: Proper nutrition during pregnancy, assisted calving when needed, clean calving environment
Detection: Placenta not expelled within 12-24 hours after calving
Metritis
Causes: Bacterial infections, poor hygiene, retained placenta
Prevention: Sanitary calving conditions, proper nutrition, postpartum monitoring
Detection: Foul-smelling discharge, fever, reduced appetite
Dystocia (Difficult Birth)
Causes: Large calf size, poor presentation, maternal factors
Prevention: Appropriate bull selection, proper body condition, breeding management
Detection: Prolonged labor, visible distress, abnormal presentation
Abortion
Causes: Infectious diseases, nutritional stress, environmental toxins
Prevention: Vaccination programs, biosecurity measures, toxin management
Detection: Premature fetal expulsion, vaginal discharge
Metabolic Disorders
Metabolic disorders often occur during periods of high nutritional demand, particularly around calving and early lactation in dairy cattle.
Key Metabolic Conditions
| Disorder | Risk Period | Primary Symptoms | Prevention Strategy |
|---|---|---|---|
| Milk Fever (Hypocalcemia) | Around calving | Muscle weakness, inability to stand, cold extremities | Proper calcium/phosphorus ratios, vitamin D supplementation |
| Ketosis | Early lactation | Sweet/acetone breath, reduced appetite, weight loss | Energy-dense diets, glucose precursors, body condition management |
| Grass Tetany | Early spring grazing | Muscle twitching, aggressive behavior, convulsions | Magnesium supplementation, mineral programs |
| Fat Cow Syndrome | Late pregnancy | Excessive body condition, calving difficulties | Body condition scoring, controlled nutrition |
Parasitic Infections
Parasitic infections can significantly impact cattle growth, reproduction, and overall health. Both internal and external parasites require different management approaches.
Internal Parasites
Common Internal Parasites and Their Impact
- Gastrointestinal roundworms: Reduced weight gain, diarrhea, anemia
- Lungworms: Persistent coughing, reduced exercise tolerance
- Liver flukes: Poor growth, bottle jaw, liver damage
- Coccidia: Diarrhea in young calves, poor growth rates
External Parasites
| Parasite | Season | Impact | Control Methods |
|---|---|---|---|
| Horn Flies | Summer | Reduced weight gain, blood loss, stress | Ear tags, pour-ons, feed additives |
| Face Flies | Spring/Summer | Eye irritation, pinkeye transmission | Dust bags, oilers, fly control programs |
| Ticks | Warm months | Disease transmission, blood loss, hide damage | Acaricides, pasture management, inspection |
| Lice | Winter/Spring | Itching, hair loss, poor appearance | Pour-ons, sprays, injectable treatments |
Foot and Leg Problems
Lameness issues significantly impact cattle welfare and productivity. Early detection and proper management can prevent chronic problems and economic losses.
Common Foot Disorders
Foot Rot
Cause: Bacterial infection in wet, muddy conditions
Symptoms: Severe lameness, swelling between toes, foul odor
Prevention: Dry lot conditions, foot baths, regular trimming
Digital Dermatitis

White Line Disease
Cause: Separation of hoof wall from sole
Symptoms: Gradual lameness, visible separation line
Prevention: Proper hoof trimming, clean dry conditions
Mastitis and Udder Health
Mastitis remains one of the most economically significant diseases in dairy operations, affecting milk quality, quantity, and cow health.
Types of Mastitis
| Type | Symptoms | Causes | Treatment Approach |
|---|---|---|---|
| Clinical Mastitis | Visible udder swelling, abnormal milk, fever | Bacterial infections, environmental factors | Immediate antibiotic therapy, supportive care |
| Subclinical Mastitis | No visible signs, elevated somatic cell count | Chronic bacterial infections | Selective dry cow therapy, improved hygiene |
