Beneficial effect of dietary copper sulphate supplementation on japanese quail performance and fatty acid profile [electronic resource].

Includes references.

A total number of 240 unsexed 21-day old Japanese quail birds (113-116 gm) were divided equally into four groups (60 birds in each). First group received basal diet+ 4% used restaurant oil (basal oxidized oil, B-OxO), second group received basal diet+ 4% non oxidized oil (control, B-NOxO). The third and fourth groups received 200 mg CuSo4/kg plus B-OxO or B-NOxO, respectively. Feeding B-OxO (1st group) reduced body weight, egg production, egg weight, fertility and hatchability percent and increased morality percent, cholesterol and triglycerides of blood, eggs and breast meat of the birds. Copper sulphate supplementation reduced the bad effect of oxidized oil on these parameters especially fatty acid profile and cholesterol content of blood, eggs and breast meat of the birds. Copper sulphate supplementation has a positive effect also when added to non-oxidized oil on body weight, egg production and cholesterol level.
