Health Problems in Fast‑Growing, Confined Broiler Chickens

Ascites (Water Belly)

Fluid accumulation in abdomen due to right‑heart failure from pulmonary hypertension. Drivers: rapid growth, hypoxia (poor ventilation), high‑altitude, excess sodium.

Leg Disorders

• Tibial dyschondroplasia, femoral head necrosis, valgus/varus deformities.
• Caused by rapid skeletal growth outpacing mineralization, slippery floors, high stocking density.

Bumblefoot (Pododermatitis)

Staph infection of foot pad from abrasions on wet, dirty litter.

Respiratory Disease

Ammonia, dust, mold, poor ventilation → tracheitis, airsacculitis, colibacillosis.

Welfare Solutions

• Slower‑growing breeds, lower stocking density.
• Enriched environment (perches, litter quality, natural light).
• Optimal ventilation, temperature, nutrition.
