DB3205/T 101—2018 梅山种猪饲养管理技术规程
This file reproduces a published official local standard for research. No original standard is authored here.
This is a Suzhou municipal agricultural local standard on feeding and management of Meishan breeding pigs, not a conformation “standard of excellence.” It does contain a formal definition of the Meishan pig and selection criteria for replacement breeding stock (including teat-number and appearance requirements). Those clauses are the parts most relevant as a breed-standard source; the rest of the document is husbandry, health, and nutrition.
