A large-scale breeding group in Jiangsu optimized the genetic foundation of its commercial-generation pigs by introducing Duroc semen from Yongcheng Gene's certified boar station. Production data indicates that under identical rearing conditions, Yongcheng-line commercial pigs demonstrated significant advantages from weaning to market weight: Daily gain reached 810g/d, exceeding the group's original level (750g/d) by 60-80g/d; feed conversion ratio dropped to 2.47, improving by 0.03-0.11. Calculations indicate this genetic advantage generated direct economic benefits exceeding 63 yuan per head in comprehensive efficiency gains for the group's commercial pigs.
Note: Data collection period: December 2023 to June 2024; Statistical data volume: 90,000 market hogs.

Yongcheng Breeding Group has established a deep partnership with Fujian Longyan Yizheng spanning from breeding stock to production systems. By introducing Yongcheng's high-performance boars, Yizheng's boar station has achieved core metrics including 100% boar training success rate, consistently high semen motility exceeding 90%, and deformity rates controlled between 5% and 10%. Simultaneously, synergistic optimization in areas such as crossbred sow multiplication has jointly driven significant improvements in overall farming efficiency and economic benefits for clients.

Since establishing a strategic partnership with Yongcheng in July 2024, Jilin Liangyuan has achieved significant improvements in pig herd production performance under the on-site guidance of Yongcheng's technical team. The farm now averages 12.63 healthy piglets per litter, with a weaning survival rate of 12.31 piglets. The 21-day weaning weight has increased from 6.8 kg to 7.4 kg, representing an 8.8% growth.
For 25 years, Liangyuan has continued to deepen its collaboration with Yongcheng. Its boar station has fully adopted high-performance Yongcheng-line boars, and its commercial pig semen has gained widespread market recognition for its consistent quality.

Since partnering with Yongcheng in June 2024, we have successfully introduced 1,150 crossbred sows, achieving a replacement utilization rate of 95.2%. With technical support from Yongcheng's team, we effectively addressed winter diarrhea challenges, attaining a farrowing room survival rate of 96.7% and a 21-day weaning weight of 7.5kg. We have now become a core supplier providing stable, high-quality piglets to major groups across Northeast China.
