An experiment was conducted to study effects of using various levels of dry pumpkin
supplementation as a source of pigment in layer diets. Different levels of dry pumpkin were
added in commercial layer diet (without any nutrients adjusted) to make five different
experimental diets containing 0, 2, 4, 6 and 8% dry pumpkin, respectively. Two hundred Hisex
Brown layers, 23 weeks of age, were randomly separated into 5 groups. Each group had 5
replications with 8 hens per replication. All birds were kept in layer cages. The results of the
experiment throughout six 14- day periods showed that there were no significant differences in
egg production, average egg weight, feed consumed per dozen eggs, livability, Haugh unit, and specific gravity of eggs. However, yolk color score was found significantly different
