Abstract

The present study aimed to examine the effects of dietary illite as a feed additive on the Haugh unit and fatty acid profiles of eggs. One hundred and twenty laying hens (48-week-old Hy-line Brown) were randomly assigned to one of the following two treatments: control or 2% illite powder. At 2 and 4 weeks, the Haugh unit values between the control and 2% illite powder groups were not significantly different (p>0.05). In addition, individual fatty acid content at 2 and 4 weeks did not differ between the treatments (p>0.05), except for palmitic (C16:0) and palmitoleic acid (C16:1) content. The addition of 2% illite powder caused no difference between the total saturated and total unsaturated fatty acids at 2 and 4 weeks (p>0.05). In conclusion, the addition of dietary illite at a rate of 2% did not improve the Haugh unit values or fatty acid profiles of eggs.
