Abstract
The effects of dietary humic substances (HS) on egg Production and egg Quality were studied using 252(55-wk old) ISA brown laying hens. laying were divided into 21 groups of 12 hens each and seven groups (experimental units) were assigned to 1) CON (basal diet), 2) HS5 (basal diet 4- 5% humic substances) or 3) HS10 (basal diet +10% humic substances) in a completely randomized block design. Hens had free access to diets and water fur 6 wk. Egg Production and egg quality were monitored over the 6-wk Period. Results showed that 10% dietary HS decreased egg Production and yolk diameter (P<0.05) compared to CON. Egg weight and yolk cole. were improved (P<0.05) in HS10 compared to CON. Egg shell breaking strength was increased significantly (P<0.05) when hens were fed HS5 diet compared to the others. There were no effects of treatments on egg shell thickness, yolk index, albumen height and Haugh nit. The results suggest that the dietary supplementation of HS at 5% or 10% decreases egg Production, but HS at 5% can increase egg shell breaking strength. Hens fed 10% HS could increase egg weight and yolk color and decrease yolk diameter.
