Introduction: The main concern in aged hens is reduced production and reproductive performance at the end of the laying period. Different types of diseases and stress during the production period are among the most important factors affecting the reduction of production performance in old hens. Today, the use of medicinal plants as natural antioxidants instead of drugs and synthetic compounds has received increasing attention. Nanofertile plant extract additive (Nano Egg Booster) contains the extract of several types of medicinal plants, including milk thistle, saffron stigma, nettle, and ginger.
Aim: This research was carried out to investigate the effects of different levels of Nano Egg Booster on productive performance, quality characteristics of eggs, and some blood parameters of laying hens post-peak production.
Material and Methods: The number of 72, 35-weeks-old Hy-Line-W36 laying hens were assigned in a completely randomized design with 4 treatments, 6 replicates, and 3 birds each and it lasted for 14 weeks. Experimental groups were designed at four levels of Nano Egg Booster including 0, 0.01, 0.02, and 0.04 % of the diet. During the test period, functional traits and quality characteristics of eggs were recorded and blood parameters were evaluated at the end of the experiment period.
Results: The results of this research showed that using a nanofertile plant extract additive in the amount of 0.01 % improved the percentage of egg production, feed conversion ratio, and eggshell thickness compared to the control (P<0.05). Serum concentrations of malondialdehyde, total cholesterol, and triglycerides decreased and the antioxidant status of plasma improved (P<0.05).
Conclusion: In general, it is concluded that supplementing of diet with Nano Egg Booster can promote laying performance, sustain egg production, and maintain the physiological function in post-peak laying hens.
