What's the difference between Landrace sow and Large White sow?

Large white pig, also known as British large white pig and Yorkshire pig, is native to Yorkshire, England. It was domesticated and cultivated by the Soviet Union. Later, after crossbreeding with China pig breeds, it was white all over, and its ears stood up forward, forming three kinds: large, medium and small, of which the largest is large white pig, which is a widely distributed pig breed in the world at present.

Landrace is native to Denmark, formerly known as Landrace. After it was introduced to China, it was named Landrace Pig because of its poor health and all-white fur. At present, it is mainly distributed in Zhejiang, Hunan, Hubei, Guangdong, Hebei and other regions.

2. Appearance difference:

The whole body hair of large white pigs is also white with some black spots in the middle, which is why many people often can't tell their nutrition. Its head is moderate in size, its nose is slightly concave, its ears are erect, its limbs are strong, its back is wide and straight, its hindquarters are plump, and its overall shape is rectangular.

Landrace pig has a long body, a little black spots on its white fur, a small head and a light neck, a long and narrow nose and mouth, big ears inclined forward or downward, straight back and waist, plump hips, developed hind legs, light front and heavy back, and strong limbs.

3. Differences in production performance:

The estrus time of large white pigs and sows is 165- 195 days, and the suitable breeding time is 220-240 days. In terms of litter, their performance is basically the same, and the initial litter size is generally around 9. In terms of slaughter, the slaughter rate of Landrace pigs is above 72%, and that of Large White pigs is above 70%, with little difference.

They are slightly different in production performance. Landrace sows generally start estrus at the age of 170-200 days, and the suitable mating age is 230-250 days.
