Effect of hydrolyzed leather shavings as food additives, partially replacing vegetable proteins in the fish food, on histopathology of rohu ( Labeo Rohita ) fingerlings

摘要

The effect of hydrolyzed chrome shavings on the histopathology of liver kidney, stomach and intestine in the fingerlings of Labeo rohita were investigated using 5%, 10% and 15% levels of chrome shavings. After supplementation histopathology of liver Kinney, stomach and intestine showed varying degrees of changes such as necrosis, pyknosis, karyolysis, hemorrhages and degeneration of epithelial linings in the tissues of groups exposed to chrome shaving. Results showed that these are time and dose dependent.
