Newborns Pigs and lambs

Frostbite Affects extremities

Damages skin Burns

Hypothermia Prevention

Trauma Causes

Open wounds Puncture wounds Fractures Sprains

Complications Initially

Hemorrhage Later

Infections

Medical attention Soft tissue wounds Radiographs Lameness evaluation

Due to sprains

Symptoms Hot and swollen areas

Endocrine System

Disorders Excess hormones Deficient hormones Hormonal imbalance

Symptoms Alopecia

Hair loss Seizuers Excess urination

Polyuria Rapid weight loss Fractures

Causes Hyperfunctions Hypofunctions

Diagnosis Blood tests Diagnostic imaging Exploratory surgery
