White Leghorn (G and J strain) hens (n=108) of 55 weeks of age were randomly allocated to six dietary treatments, each with 18 birds in a completely randomized design. The dietary treatments consisted of one basal control (D1), supplemented with 0.5% arjuna bark powder (D2), 0.5% guggul resin powder (D3), 0.5% cinnamon bark powder (D4), 1% amla pulp powder (D5) and combination of 0.25% arjuna bark powder + 0.25% guggul resin powder + 0.25% cinnamon bark powder + 0.5% amla pulp powder (D6). The basal diet consisted of 2700 ME (kcal/kg) and 17% CP with 3% calcium and 0.4% available phosphorus. During 6 week period of feeding there was a non-significant difference in terms of egg production, egg weight, feed intake and feed efficiency amongst the dietary treatments. The egg yolk cholesterol of the hens on 14 th and 28 th day of feeding of diets with herbs did not reveal much difference, while on 42 nd day the egg yolk cholesterol reduced significantly in hens received guggul resin alone (D3) or the diets containing mixture of herbs (D6).
