- Abstract
The aim of this experiment was to study the effect of biofermented feed on the performance, egg quality and intestinal microflora of laying hens. A total of 18 000 healthy laying hens at 43 weeks of age with similar egg production rate and average egg weight were selected and randomly divided into 2 groups (6 replicates per group). The control group was fed the basic diet, and the experimental group was fed the basic diet with 5% fermented feed. The experimental period was 60 days. The results were as follows: ① compared with the control group, the egg production rate of the experimental group increased, and the feed to egg ratio, egg breakage rate and dead rate were reduced. ② On the 60th day, the average egg weight, egg white height, yolk color, eggshell weight and yolk weight of the test group were all extremely significantly higher than those of the control group (P<0.01), and the eggshell thickness was significantly higher than that of the control group (P<0.05). ③ Compared with the control group, the superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities of the test group were significantly increased (P<0.05); malondialdehyde (MDA) content was significantly decreased (P<0.05); and the immunoglobulin G (IgG) content was highly significantly increased (P<0.01). ④ Compared with the control group, the experimental group of laying hens showed an increase in the abundance of the intestinal thick-walled phylum, a decrease in the abundance of the anaplastic phylum, an increase in the intestinal thick-walled phylum/anaplastic phylum (F/B) ratio, and an increase in the diversity of the community. It can be seen that the addition of biofermented feed to the ration can improve the production performance of laying hens, improve egg quality, enhance the antioxidant capacity and immunity of laying hens, and improve the intestinal microflora of laying hens. Therefore, it is important to use biofermented feeds to improve the performance and intestinal health of laying hens, and this paper can pro‐ vide a reference for the popularization and application of biofermented feeds in laying hens' diets.
