According to the research team, the donor goats recorded average annual milk yields exceeding 2,800 kilograms, significantly outperforming standard dairy goat production levels. The animals also demonstrated strong milk fat and protein content, reliable reproductive performance, disease resistance and adaptability to environmental conditions, making them valuable genetic resources for the dairy goat sector.

The breakthrough relied on an advanced molecular breeding platform that combined genomic selection with somatic cell cloning technology. Researchers optimized the full cloning process, including cell isolation, embryo reconstruction, embryo transfer and pregnancy monitoring, ultimately achieving successful large-scale replication of elite dairy goat genetics.

Scientists said the technology could dramatically reduce breeding timelines compared with conventional methods. Traditional dairy goat improvement programs often require eight to 10 years to establish superior herds, while cloning enables faster multiplication of elite animals and improves the preservation of desirable production traits across generations.
