A 10-week trial with 56,000 laying hens reveals: extended peak egg production, ovaries 20% younger, and a 34.9% increase in follicle count—Qimei Su delivers the results.

Editor's Note: In layer hen farming, the late laying period ( 50 After a certain number of weeks, declining egg production rates and deteriorating egg quality are challenges that trouble every farm owner. Guangdong nuacid NIC The R&D team collaborated with a poultry company in Fujian Province, in 5.6 Wan Yu Jing Hong 1 A large-scale field trial was conducted at a commercial layer farm. The results showed that: in 55~60 Added to the diet at a certain age 200g/t Qimei Su (flavonoid complex), serum SOD Antioxidant enzyme activity increased 14% , ovary SOD Antioxidant enzyme activity increased 24.6%, Ovarian index improvement 20.0% , egg weight increased 10.0% , yolk-to-white ratio improved 25.8% ! Data sourced from large-scale farming operations.
Under big data conditions, the use of Qimei can steadily increase peak egg production in laying hens during the later stages of their laying period.
Production performance is the primary metric of concern for poultry farms. The results show that, compared with the standard laying rate, Group A’s laying rate was slightly lower than the Jinghong No. 1 standard, and its laying rate exhibited substantial fluctuations, with a coefficient of variation of 1.82%. This indicates that the poultry farm has experienced stress, resulting in production performance below expectations.
After the subsequent addition of Qimei Su, during weeks 55–60, the laying rate did not decline significantly compared with the earlier period; instead, it increased by 0.5%. Compared with the standard laying rate of Jinghong No. 1, the laying rate showed a steady improvement of 2.7%, with minimal fluctuations and an intra-group coefficient of variation of 1.28%. These findings indicate that Qimei Su mitigates the adverse effects of stress on egg production rates and, to some extent, reverses the natural decline observed in the later stages of the laying period. Helps extend the peak egg-laying period.

Qimei Su improves egg weight and yolk ratio in the late laying period.
Egg quality directly affects the commercial value and market competitiveness of eggs. As shown in Table 1, the average egg weight of hens in Group B was significantly higher than that of Group A, increasing by 10.0%; the yolk ratio also increased significantly, by 25.8%. This indicates that the flavonoid complex promoted yolk deposition and increased egg weight, thereby enhancing the nutritional value and economic benefits of the eggs.

Effect of Qimei Su on the Ovarian Index of Laying Hens in the Late Laying Period
The organ index reflects the development and functional status of visceral organs. As shown in Figure 3, the ovarian index of laying hens in Group B was significantly higher than that of Group A, increasing by 20.0%. This indicates that the flavonoid complex exerts a specific promoting effect on reproductive organs, helping to maintain reproductive health in laying hens during the late production phase. The increased ovarian index provides a physiological basis for subsequent follicular development and the maintenance of egg-laying performance.

Qimei Su increases the number and index of small yellow follicles in laying hens during the late laying period.
Follicular development is a direct reflection of laying hens’ egg production capacity. The results (Figure 4) show that the number of small yellow follicles in Group B tended to increase by 34.9%. This upward trend in the number of small yellow follicles suggests that the flavonoid complex may have promoted early follicular development, potentially supporting the maintenance of subsequent egg-laying rates.

Qimei Su enhances the antioxidant capacity of serum and ovaries in laying hens during the late production phase.
Antioxidant capacity is an important indicator of the health status of laying hens, particularly in the later stages of production. As shown in Figure 5:
Serum antioxidant capacity was significantly enhanced: In Group B, hepatic SOD activity increased from 89.18 U/mL to 99.6 U/mL (P<0.01), representing a 12% increase; serum MDA levels decreased from 4.20 nmol/mL to 2.46 nmol/mL (P<0.05), a reduction of 41.4%;
Enhanced ovarian antioxidant capacity: Ovarian SOD activity increased from 1110.4 U/mg to 1383.2 U/mg (P<0.05), an increase of 24.6%. Ovarian GSH-Px enzyme activity rose from 999.02 U/mg to 1047.71 U/mg. Ovarian MDA content decreased from 19.82 nmol/mg to 12.05 nmol/mg (P<0.05), a reduction of 39.2%.
These data indicate that the flavonoid complex effectively reduces lipid peroxidation levels by enhancing antioxidant enzyme activity in serum and ovaries, alleviates oxidative stress during the late laying period, and delays the aging process of the reproductive system.

Conclusion
Red in Beijing 1 Laying hens in the late stage of egg production ( 55~60 Added to the feed at (weeks of age) 200g/t Qimei Su can stabilize egg production rates, effectively extend the peak laying period, and simultaneously improve egg quality (increased egg weight). 10.0% Egg yolk ratio improvement 25.8% ), promoting ovarian development (increased ovarian index) 20.0% , the number of small yellow follicles increased 34.9% ), and enhance the body’s antioxidant capacity, thereby delaying aging of the reproductive system.
