Effects of Mitragyna speciosa Leaf Powder Supplementation in Layer Diet on Production Performance and Egg Quality

Abstract

The objective of this study was to examine the effects of kratom leaf powder supplementation in layer diet on production performance and egg quality. Forty 73-week-old Hisex Brown hens were divided into 4 treatment groups with 5 replications of 2 hens each. A basal diet supplemented with kratom leaf powder at 0, 0.5, 1.0 or 2.0% of diet for 8 weeks were fed to these hens. Body weight, egg production, egg weight, egg mass, feed intake and feed conversation ratio were recorded. Egg quality was measured on the last day of the experiment. The results showed that supplementation of kratom leaf powder at 0.5% level gave better egg production, egg mass and feed conversion ratio than other groups (P < 0.01). In addition, the supplementation of kratom leaf powder resulted in a reduction in feed intake (P < 0.01). In terms of egg quality, it was found that eggshell weight, eggshell strength, eggshell thickness, yolk weight, albumen weight, yolk color and Haugh unit were not statistically different (P > 0.05). From these findings, it can be concluded that kratom leaf powder can be supplemented in layer diet at 0.5% level.
