Utilization of agricultural wastes in animal nutrition is a matter of great concern. Dried citrus pulp (DCP) is a potential
source of some valuable nutrients for animal and poultry. In an experiment with completely randomized design, the effect of
different levels (0%, 4%, 8%, 12%, and 16%) of DCP was evaluated on performance, egg quality, and blood parameters of laying
hens from 25 to 37 weeks of age. The birds were randomly allocated to five groups with six replicates and three birds in each
replicate. The results showed that with increasing the level of DCP up to 12%, there were no significant differences among
treatments for feed intake, egg production, egg mass, feed conversion ratio, final body weight, yolk index, and yolk color.
There were no significant differences between treatments in shell thickness, eggshell index, egg score, and Haugh unit. Utilization
of DCP up to 16% significantly increased serum glucose and high-density lipoprotein and reduced cholesterol, low-density lipoprotein,
and triglycerides (P < 0.05). Results of the present study indicated that use of 12% DCP in laying hen diets had no adverse effect on performance
and egg quality of laying hens in early phase of production. 相似文献
