Abstract
Egg yolk is considered to be one of the main sources of cholesterol for humans. The purpose of this study was to investigate the effect of feeding laying hens with dried horse chestnut (Aesculus hippocastanum) seed grains as 0.25%, 0.50% and 1.00% supplements to their basal diet on egg yolk cholesterol levels. Although there is a vast amount of researches about the medical and pharmaceutical effects of extracts of horse chestnut bark, leaves and seeds, to my knowledge, there is no academic research on the effect of feeding poultry with horse chestnut seeds without processing them chemically on egg yolk cholesterol level. My hypothesis predicted that dried horse chestnut seed supplement in non-toxic small amounts of 0.25%, 0.50% and 1.00% in the basal diet of laying hens is going to lower the egg yolk cholesterol level. Sixty Brown Nick breed laying hens were used in the experiment by dividing in 4 groups of 15 hens and each group in 5 trial groups of 3 hens. The first group was the control group and other three groups were fed with basal diet and water ad libitum for four weeks with dried grains of horse chestnut seed core grains. A total of 160 eggs were collected (10 from each test group at the end of each week) to analyze the egg yolk cholesterol level by using the enzymatic colorimetric test for cholesterol with lipid clearing factor method as described in Boehringer Manheim Gmbh Biochemica, 1989. At the end of the experiment, no health issues or deaths of hens were observed. The feed efficiency of laying hens were increased by 3.5% when fed with 1.00% dried horse chestnut seed grain supplement. The results showed that 0.25%, 0.50% and 1.00% horse chestnut seed supplement in the basal diet of laying hens does not affect egg yolk cholesterol levels significantly.
