The pride of Saikai City, Nagasaki — an SPF-certified brand pork raised under strict hygiene management and on a grain-based diet.
Nagasaki Daisaikai SPF Ton is a Japanese brand pork (meigara-buta) from Yokose-go, Saikai-cho, Saikai City, Nagasaki Prefecture, managed by Daisaikai Farm Co., Ltd. Breed / crossbreeding: Female (Landrace ♀ × Large White ♂) × Duroc.
Nagasaki Daisaikai SPF Ton (Nagasaki Greater Saikai SPF Pork), raised in Saikai City, Nagasaki Prefecture, is a committed brand pork produced by thoroughgoing hygiene management and a healthy rearing environment. ‘SPF’ stands for Specific Pathogen Free — meaning raising piglets born from healthy sows in a clean environment where disease-causing bacteria cannot intrude.
At Daisaikai Farm — upon entry and exit of the farm, vehicle and personnel disinfection is thoroughly maintained, and staff are obligated to shower and change into dedicated clothing before entering the pigsty — a thoroughgoing disease prevention system is in place. The SEW method (Segregated Early Weaning) is adopted — by separating rearing in stages from pregnancy/farrowing barn through piglet barn and further to fattening barn — pathogen intrusion from outside is blocked.
A designated compound feed richly containing barley, wheat, and feed rice is used — in the finishing period, further abundant grains are given to draw out rich umami. Furthermore, by utilizing food by-products such as shochu lees and syrup lees in liquid feed — minimal drip is produced, with a rich, deep flavor born. After 70 days of age, feed is switched to antibiotic-free — thoroughgoing production of pork that can be put in the mouth with confidence.
The meat born from such devoted rearing has fine muscle fibers and a smooth texture. The sweetness of the fat and the inherent umami of pork spread in the mouth — minimal scum during cooking is also a major appeal. Please do enjoy at your table this specialty — nurtured by the rich landscape of Nagasaki where the whirlpools of Saikai Bridge flow.
