Blood fat profile of laying hens consuming rations fortified with citric acid and beta-carotene

Abstract Extreme climate change greatly affects the metabolism of laying hens due to their intolerance high environmental temperatures. Hence, improve metabolism, feed quality also needs be improved. This study aims determine blood lipid profile consuming a diet rich in citric acid and beta-carotene (β-carotene). During study, 200 Lohmann strain aged 35 weeks ration with crude protein content 18.39% metabolic energy 2960 Kcal/kg were used. The treatment was fortification various levels β-carotene sources 0.2% acid, namely T0 (without acid), T1 (0.1% + T2 ( 0.15% T3 (0.2% acid). data analyzed by analysis variance further testing Duncan’s Multiple Range Test. Furthermore, observed variables cholesterol HDL, as well triglycerides. results showed that significantly affected but had no significant effect on concentration HDL Considering these results, it concluded ratio decreased amount fat blood.
