In February 2025, Yongcheng Breeding Group once again achieved an absolute advantage and topped the list of February calving age for Duroc pigs in the national core breeding farms! This is already the 13th consecutive month that Yongcheng has held the top position since February 2024! It fully demonstrates its strong strength and leading position in the field of pig breeding.

Ranking of the national core breeding herd Duroc pig performance at the February calving age

Analysis of February Data from the National Core Breeding Facility for Pigs

The report shows that Yongcheng Breeding Group not only ranks first in the growth rate of Duroc pigs, but also leads in the number of Duroc pigs measured. Among them, the number of Duroc boars measured is 254, and it only takes 151.92 days to reach 120 kg of age after correction; the number of Duroc sows measured is 268, and it only takes 157.03 days to reach 120 kg of age after correction.

The average correction time for Duroc pigs to reach 120 kg in age is only 154.55 days. This is 8 days faster than the second-place competitor, 12 days faster than the fifth-place competitor, and 26 days faster than the tenth-place competitor!

The corrected age of Yongcheng Dorper boars is 15-20 days faster than the national average.Behind this honor lies the 33-year dedication and perseverance of Yongcheng Breeding Group to pig breeding. It is also a vivid embodiment of the breeding philosophy of "Leading from Generation to Generation and Never Stopping". In the monthly rankings of national core breeding farms, the corrected age of Yongcheng Duroc boars has advanced by 15-20 days compared to the national average.

Advanced breeding technology leads the innovation of seed industry

Yongcheng Breeding Group has always been committed to technological innovation and actively introduces and applies advanced breeding technologies. The group adopts a combination of quantitative genetics breeding and whole genome breeding methods to build an outstanding breeding system.
 Large-scale measurement of pig growth performance
Yongcheng insists on large-scale measurement of pig growth performance. In 2023, the total number of measured pigs reached 21,392, and in 2024, it exceeded 25,486. Through genetic evaluation methods such as BLUP for cross-population genetics assessment and ssGBLUP for genome assessment, the genetic value of breeding pigs is accurately evaluated, providing scientific basis for selection and mating.
