The influence of different levels of expanded perlite on the performance
and egg quality traits was studied in laying hens. Forty Lohmann Brown
females at 30 weeks of age were randomly assigned to four groups
consisting of five replicates with two hens in each. Four diet groups
were supplemented with 0\% (control group), 1\%, 2\%, and 3\% perlite,
respectively. Feed and water were provided ad libitum. There were no
significant differences in final body weight, feed intake, egg yield,
and egg weight. Feed conversion ratio and egg weight decreased with
addition of 2\% perlite. Dietary perlite supplementation has no
significant effects on shape, yolk, and albumen index. Haugh unit was
affected significantly by addition of 2\% perlite. Fecal pH, dry matter,
and NH3-N did not significantly differ among treatments. Dietary perlite
has no negative effect on performance and egg quality traits except 2\%
perlite group. Dietary expanded perlite can be added at 1\% level in
laying hen rations without changing the animal performance.
