The difference between Landrace and Large WhiteThere were differences between Landrace and Large White in the following aspects:
1. ** Physical Appearance **:
- The Landrace pig has a long body, a small head and short neck, a long nose and a long mouth, long ears, straight back and waist or slightly arched, straight abdominal line, plump legs and buttocks, delicate appearance, white fur, and occasionally small dark spots at the corner of the eye or the root of the tail.
- Large White Pigs had white fur, moderate head size, slightly sunken face, medium-sized ears that stood up, deep and wide chest, long back and waist, full and tight abdomen, plump legs and buttocks, strong limbs, small black spots allowed on the skin of the corners of the eyes and forehead, but the additional Large White Pigs did not have obvious sunken face and large ears.
2. ** Breed characteristic **:
- The Landrace had a streamlined body, high lean meat percentage, good reproductive performance, and high milk production, but its limbs, especially the hind legs, were relatively weak. When the environment was not good, stress symptoms might occur, and it was not as good as the Large White as a mother.
- Large white pigs were the ideal lean-meat type of pigs. They had tight meat, little fat, strong limbs, strong physique, strong reproductive ability and strong milk secretion. They were not prone to stress reactions to the environment. Large-scale pig farms in China were mostly used as maternal pigs.
3. ** Production performance **:
- The first estrus period of Landrace sows was 6 - 7 months. At the age of 8 months, they weighed 110kg, had 11 litters, and had an average daily gain of more than 770g. The feed conversion ratio was lower than 2.7.
- The first estrus period of the Large White sow was 6 months. At the age of 7 - 8 months, the weight was 110kg, the litter size was 11 - 12, the average daily gain was more than 820g, the feed conversion ratio was lower than 2.7, the lean meat rate was 64%, and the weight could reach 100kg at the age of 165 - 168 days.
