ABSTRACT

A study was conducted to investigate the effect of vitamin E on lipid blood parameters of laying ducks kept under a village system. The study involved 600 local laying ducks (Tegal ducks) aged 12.3 ± 0.9 months. The ration contained 18.91% protein, 64.48% dry matter, 5.02% fat, 8.91% crude fiber, 10.03% ash, 2.29% calcium, and 0.78% phosphorus. A Completely Randomized Design was used with 4 groups: control, and vitamin E administration (D1= 400 IU, D2= 500 IU, and D3=600 IU per day). Each treatment group was replicated 6 times with 25 laying ducks per replication. Commercial vitamin E was administered for 3 months. At the end of the study, blood samples were collected for hematologic tests. The results showed that cholesterol and LDL levels were significantly lower (P<0.05) in D2 and D3; HDL was significantly higher (P<0.05) in D1, D2, and D3; while triglycerides were significantly lower (P<0.05) in D1 and D3. it is concluded that vitamin E supplementation has decreased blood cholesterol, LDL, and triglycerides levels and increased blood HDL levels of laying ducks under the village management system.
