Qualities• Meat Quality• typically dark red in color,• maintains moisture well and has good fat marbling throughout • all highly desirable qualities in cuts of pork. • significant amount of lean muscle and high tenderness• High carcass yield• High quality meat & delicious

•Duroc qualityDuroc gives the meat unbeatable texture, juiciness and flavour. The fatty streaks between the muscles give the meat its unique organoleptic properties so keenly enjoyed by even the most demanding palates.

Qualities cont.

• Growth• Duroc pigs are one of the fastest growing breeds• Sow mature body weight- 204 to 295 kg & boar -227 to 340 kg• very hardy. • Can tolerate both cold and warm climates • Average lifespan is 10-15 years

Qualities cont.• Temperment• genle• Males are little aggressive during breeding season

• Socialize them• Must be carefully handled

• Can be trained easily

Produce large litters (9.78)Suitable for cross breeding and upgrade other breeds( superior genetic quality)Good mothering abilityExcellent feeding capacity and produce large quantities of milk

• Breeding problems• Breed with a smaller boar• If litter is too large sow will abandon smaller piglets.

• Smaller piglets have to be hand fed• Cross breed with Hampshire will eliminate the breeding problems

• Most frequently used sire for terminal cross breeding programs• Durability, growth, and muscle qualities attributes, carcass leanness

and feed efficiency • provide 100% heterosis when mated to Yorkshire x Landrace F1

Duroc to improve robustness and longevity in their sow herds.
