The study was carried out to investigate effect of Moringa oleifera Lam. leaf powder
supplementation in layer diet on production performance and egg cholesterol, and conducted at Lampang
Animal Nutrition Research and Development Center, Hangchat, Lampang. Totally one hundred and sixty
commercial laying hens were used.The experiment stated at 31 weeks old of age and finished at 57 weeks
of age of the laying hens. The experimental design was completely randomized design (CRD), the hens were
divided into four treatments in four replications with 10 hens each. The treatment groups were (1) No
Moringa oleifera Lam. leaf powder supplementation (0%, (2), (3) and (4) supplemented Moringa oleifera
Lam. leaf powder 2%, 4% and 6% respectively. The dietary treatments were isonitrogenous and isocaloric.
The hens were kept in individual cages in open-house system and lighted 16 hours per day.
The results showed that Moringa oleifera Lam. leaf powder supplementation did not effect to
egg weight, egg mass, daily feed intake, feed conversion ratio, survival rate, egg composition such as yolk,
albumen and shell percent, particularly egg quality such as albumen height, haugh unit and shell thickness
(p>0.05). However, egg production and yolk score was increased, while egg cholesterol decreased. Moringa
oleifera Lam. leaf powder supplementation 2, 4 and 6% showed hen day production 86.23, 87.25 and
87.03 %, and yolk color score 8.01, 8.96 and 9.19, particular yolk cholesterol 13.00 12.51 and 12.46 mg/g
yolk, respectively. There were significantly different when compared with the group were given no Moringa
