ABSTRACT
This study investigates the effect of supplementation of Perilla seeds (PS) on the performance, egg quality, blood biochemical parameters, and egg yolk fatty acids composition in the diet of egg-laying chicken. A total of 1600 Lohmann laying hens were randomly assigned to four different groups with 4 replicates each (100 chickens/replicate) and were subjected to varying PS concentrations (PS0, PS6, PS12, and PS18; 0%, 6%, 12%, and 18%, respectively) for four weeks, including an acclimation period of one week. The results showed no significant differences among the groups for average egg weight (P > 0.005). The laying rate (%), feed conversion ratio (FCR) and average feed intake (AFI) decreased significantly for birds fed on 18% PS as compared to the other treatments (P < 0.005). Haugh unit, albumin height, egg-shape index and eggshell thickness among hens fed PS diets were greater averaging 80.53, 7.00, 1.29, 0.34 compared to 76.84, 6.86, 1.25 and 0.32 from Control hen eggs (P < 0.05). Serum analysis showed a trend towards elevated levels of glucose (Glu), total protein (TP) and aspartate aminotransferase (AST) among treatments. Total cholesterol (TC), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) decreased for the birds fed on 6% PS. The fatty acid composition of egg yolk showed a substantial reduction for α-linolenic acid and docosahexaenoic acid increased significantly by the incorporating PS in the diet (P < 0.001). PS incorporation in diets resulted in significant improvements in both performance indicators and greater amounts of α-linolenic acid and DHA in egg yolks. These findings indicate that PS at 6% inclusion has the potential to improve fatty acid profiles of egg yolk without any adverse effect on performance of egg quality.
