บทคัดย่อ (ABSTRACT)
Abstracts This trial was conducted to investigate the effect of dietary addition of flaxseed and fish oil on productive performance, egg yolk fatty acid composition, and on cholesterol levels in yolk and blood serum of laying hens as well as sensory evaluation of eggs. In total, 200 laying hens were divided into 5 groups. Ten birds were randomly assigned to each treatment (5 cages) and each treatment was replicated 4 times. The birds were fed a standard layer diet (17% CP; 2800 Kcal/ME/kg diet). The diets contained 0-0, 10-1.5, 15-1.5, 10-3.0 and 15-3.0% combinations of flax seed to fish oil in FS0 FO0 , FS10FO1.5, FS15FO1.5, FS10FO3.0 and FS15FO3.0 treatments, respectively. When compared to the controls, only FS15FO3.0 hens consumed more feed per day (P0.05). Key words: Cholesterol, fish oil, flaxseed, laying hen, yolk fatty acids
