Nutritional effects of spottail shark (Carcharhinus sorrah)‎ liver oil on biochemical and embryological changes of white mice (Mus musculus)‎

الملخص EN

This investigation was carried out in an attempt to study the nutritional effects of Spot tail shark liver oil (SLO) on blood serum lipids and embryological changes of experimental mice as well.

The blood serum lipids levels were significantly different in control group compared to that fed provender mixed with 5 and 10 % shark liver oil.

The beneficial effect of shark liver oil appear in the raise of high density lipoprotein (HDL) cholesterol and in the adverse trend in low density lipoprotein (LDL) cholesterol level which showed decreasing with adding the oil to mice provender.

During pregnancy there are no such good effects with adding of shark liver oil to animal diet.

It causes significant decreases in weight and length of fetuses and neonatal (prenatal and postnatal), and decrease of placenta weight.

Addition to congenital malformations appeared, such as Anencephaly and musculoskeletal abnormalities, whereas significant increases appeared in weight of liver, kidney and spleen for mothers and neonatal.
