A. Jaundice
Jaundice is a clinical sign which often arises in diseases of the liver and biliary system but also in diseases in which there are no lesions of these organs.
Although jaundice is a result of the accumulation of bilirubin, the staining is much more pronounced with direct bilirubin than with indirect bilirubin. The levels of bilirubin in blood also affect the intensity of the jaundice.

The staining of jaundice is due to staining of tissues, especially elastic tissue. Hemolytic jaundice is common in animals and it¢s being caused by bacterial toxins, invasion of erythrocytes by protozoa or viruses, inorganic and organic poisons and immunological reactions is well known.
Clinically hemolytic jaundice is characterized by a moderate degree of yellowing of the mucosae, and by the presence of haemo-globinuria in severe cases. Clinic pathological findings indicate the presence of anemia, an increase in urobilinogen and an absence of bilirubin in the urine, and a preponderance of indirect bilirubin in the serum.
Jaundice due to Hepatic Cell Degeneration. The cause may be any of those diffuse diseases of the liver which cause hepatic cells degenerating and which are listed under hepatitis. Because there is only partial obstruction of biliary excretion, the changes in serum and urine lie between those of hemolytic jaundice and extra hepatic biliary obstruction. Increasing of serum levels of total bilirubin is caused by retention of direct bilirubin. Its passing out in the urine causes an elevation of urine levels. Rising of the urobilinogen levels in the urine is also observed.

B. Hepatitis
Clinical Findings. The cardinal signs of hepatitis are anorexia, mental depression, with excitement in some cases, muscular weakness and jaundice but in the terminal stages somnolence, recumbency and coma with intermittent convulsions. Animals which survive the early acute stages may evidence photosensitization, a break in the wool or hair leading to shedding of the coat and susceptibility to metabolic strain for up to a year.
The initial anorexia is often accompanied by constipation and punctuated by attacks of diarrhea. Vomiting may occur in pigs. The nervous signs are often pronounced and vary from lethargy with yawning, or coma, to hyper excitability with muscle tremor, mania and convulsions. A characteristic syndrome is the dummy syndrome in which we may observe the affected animals, pushing with their heads making no response to normal stimuli and blindness. There may be subacute abdominal pain usually manifested by arching of the back, and pain on palpation over the liver. The enlargement of the liver is usually not palpable.

Jaundice and edema may or may not be present and are more commonly associated with the less acute stages of the disease. Photosensitization may also occur but only when the animals are on a diet containing green feed and are exposed to sunlight. A tendency of bleeding more freely than usually it may be observed. In chronic hepatic fibrosis the signs are similar to those of hepatitis but develop more slowly, and persist for longer periods, often months. Ascites and the dummy syndrome are more common than in hepatitis.
