Landrace and Large White pigs could be distinguished from the following aspects: 1. ** Appearance ** - ** Landrace **: White fur, long body, small head and short neck, long nose and long mouth, long ears, straight back and waist or slightly arched, flat abdominal line, plump legs and buttocks, delicate appearance, occasionally small dark spots at the corner of the eye or tail root. - ** Large White Pig **: All white fur, moderate head size, slightly sunken face (the additional Large White pig's face is not obviously sunken and the ears are larger), medium-sized ears, upright, 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. 2. ** Species Specialties ** - ** Landrace pig **: Its body is streamlined, has a high lean meat percentage, good reproductive performance, and high milk production. However, its limbs, especially its hind legs, are relatively weak. When the environment is not good, stress symptoms may occur. As a mother, it is not as good as a large white pig. - ** Large White Pig **: It is an ideal lean-meat type pig breed. It has tight meat, less fat, strong limbs, strong physique, strong reproductive ability and strong milk secretion. It is not easy to have a stress reaction to the environment. At present, large-scale pig farms in China are mostly used for maternal pigs. 3. ** Production Performance ** - ** Landrace sows **: 6 - 7 months of puberty, 110kg of weight at 8 months of age, 11 litter size, average daily gain of more than 770g, feed conversion ratio of less than 2.7, lean meat percentage of more than 65%, 100kg of weight at 170 - 173 days of age. - ** Large white sows **: 6 months of puberty, 110kg of weight at 7 - 8 months of age, 11 - 12 litter size, average daily gain of more than 820g, feed conversion ratio of less than 2.7, lean meat rate of 64%, 100kg of weight at 165 - 168 days of age.

There 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.

The advantages of the big white pig: It originated from the United Kingdom and is a world-famous lean-meat pig breed. It has the characteristics of strong adaptability, fast reproduction speed, fast growth speed, high lean meat rate, good meat quality, etc. It is an ideal lean-meat pig breed with tight meat quality, less fat, strong limbs, strong physique, strong reproductive ability and strong milk secretion, and is not easy to have a stress reaction to the environment. It has strong disease resistance, strong adaptability, and tolerance to coarse food. Its first estrus period is 6 months, its weight is 110kg at 7 - 8 months old, and the litter size is 11 - 12 heads. The average daily gain was more than 820g, the feed conversion ratio was less than 2.7, the lean meat percentage was 64%, and the body weight could reach 100kg at the age of 165 - 168 days. Disadvantages: Fewer papilles, relatively poor productivity. The advantages of Landrace pigs: They are native to Denmark. The obvious advantages are the large number of litters, fast growth, and low feed consumption. The carcass lean meat rate is high. At the age of 6 months, the weight can reach 200 pounds. The feed conversion rate is 2.8: 1. The selling price of live pigs is relatively high. The birth rate is more, the milk is sufficient, and the weaning litter weight is higher. Disadvantages: Weak physique, poor resistance, high requirements for feeding techniques and environment, sows are prone to reproductive obstacles and hoof cracks; long limbs, thin skin, weak resistance to the sun and skin diseases; Although the lean meat rate is high, the overall physique is not good, often causing irreparable losses to pig farmers.

The big white pig was native to England, also known as the Great Yorkshires. Small dark spots occasionally appeared on the forehead (not in the stage of small and medium pigs). The ears were of moderate size and upright, the mouth was straight, the face was flat or slightly concave, the head was of medium size, the lower jaw occasionally drooped, the chest was wide, the back and waist were straight, the abdomen was well developed but not drooping, the legs and buttocks were muscular, and the limbs were thick and strong. Overall, it showed a "rectangular" body shape. The average number of piglets produced in a large white pigsty was usually more than 10, and the back fat at 100 kg of body weight usually did not exceed 20 mm. The growth speed was fast, and it usually reached 100 kg of body weight 150 - 155 days after birth. The carcass lean meat percentage was usually 65%. The Landrace was native to Denmark, formerly known as Landrise. Its head was narrow and long, its ears inclined forward, its body length was longer than that of ordinary pigs, it had 1 - 2 more cervical vertebrae, its chest was shallow, its back was flat or slightly arched, its thighs were plump, and its buttocks were developed. Each litter had 10 - 12 pigs, and the newborn piglet weighed 1 - 1.5 kg. The adult boar could weigh more than 250 kg. Landrace pigs grew fast, produced a lot of meat, had good meat quality, and had high feed utilization rate. However, they had the shortcomings of weak limbs, thin skin, and weak resistance to the sun and skin diseases. Changbai's novel is equally exciting. Everyone is welcome to click and read it!

Overall, it showed a "rectangular" shape. Its whole body was covered in white hair, but small dark spots were occasionally seen on the forehead.(Dark spots do not appear at the stage of small and medium pigs.) The whole body of the Landrace pig is white, the head is narrow and long, the ears are inclined forward, the body length is longer, there are 1 to 2 more vertebrae than ordinary pigs, the chest is shallow, the back is flat or slightly arched, the thighs are plump, and the buttocks are developed. In terms of performance, Large White pigs had strong reproductive ability, high feed conversion rate, high slaughter rate, and strong adaptability. The average number of piglets produced in a litter was usually more than 10, and the back fat of 100 kg of body weight usually did not exceed 20 mm.

Large White and Landrace pigs could be used as gilts, each with its own advantages and disadvantages. From the perspective of reproductive performance, the number of litters of Landrace pigs was generally slightly higher than that of Large White pigs, with a difference of about 1 - 2 pigs. From the perspective of adaptability to the environment, Large White pigs were short and fat, with well-developed limbs, which were more suitable for rural free-range rearing; Landrace pigs had short front legs and long waist, which were more suitable for house rearing. From the birth weight of the piglet, the Landrace was better than the Large White. The average weight of the piglet produced by the Large White was 1.3 kg, while the Landrace was 1.36 kg. In terms of lifespan, the average lifespan of a Large White pig was 6 - 10 years, while that of a Landrace pig was 8 - 10 years. When selecting a gilt, in addition to the characteristics of the pig breed itself, it was also necessary to pay attention to the individual's body shape (such as the head and neck are light, the hind body is full, the limbs are strong, the abdomen is slightly protruding, the Pelvic shelf is wide, etc.), health status (water gate development, the number and arrangement of teats, whether the legs and feet are normal, eye condition, breathing rate, mental state, etc.), growth speed, estrus, and other factors.

Large white pigs and Landrace pigs had their own advantages and disadvantages when used as breeding sows. In terms of litter size, Landrace sows may have slightly more litter sizes than Large White sows, with a difference of about 1 - 2 pigs per litter. In terms of estrus and breeding time, the estrus time of Large White sows was generally 165 - 195 days old, and the suitable breeding time was about 220 - 240 days. The estrus time of Landrace sows was generally 170 - 200 days old, and the suitable breeding time was about 230 - 250 days. Landrace pigs grew fast. At six months of age, they could weigh up to 200 pounds and had a high lean meat percentage (about 64% lean meat percentage). However, their physique was weak and their resistance to stress was poor. They had high requirements for feeding techniques and the environment. Sows were prone to reproductive problems and hoof cracks. Large White pigs had a lean meat percentage of 62%, and their body weight could reach 200 pounds before they were six months old. The feed conversion rate was 2.8: 1 like Landrace pigs, but the meat quality was excellent, the resistance was strong, the requirements for the environment were not high, and the mortality rate was low. Therefore, if the breeding technology and environmental conditions were better, and the pursuit of higher lean meat rate and growth speed, the Landrace pig could be chosen as the breeding sow; if the breeding technology and environmental conditions were limited, and the sows were hoped to have strong resistance and meat quality welcomed by the slaughterhouse, then the Large White pig was more suitable as the breeding sow.

Landrace boars weighed about 400 - 500 kilograms, sows weighed about 300 kilograms, and Duroc sows were of moderate size. From the upper limit of the boar's weight, the Landrace was larger, but from the description of the sow's body size, the Landrace's weight data was clear and relatively larger, while the Duroc sow was only of moderate size and was difficult to compare. In general, it was impossible to determine with certainty which was bigger, the Duroc or the Landrace, based on the available information. Changbai's novel is equally exciting.

Landrace pigs originated from Denmark, formerly known as Landrise. They were a lean-type pig breed with a worldwide distribution. In 1887, it was bred from a cross between the Yorkshires and the Danes. In 1961, it became the only breed in Danes. Its whole body is white, its head is narrow and long, its ears are inclined forward, its body length is longer than that of ordinary pigs (1 to 2 more vertebrae than ordinary pigs), its chest is shallow, its back is flat or slightly arched, its thighs are plump, and its buttocks are developed. Each litter has 10 to 12 litters. The newborn piglet weighs 1,000 - 1.5 kg, and the adult boar weighs more than 250 kg. This kind of pig grew fast, produced a lot of meat, had good meat quality, and had a high feed utilization rate. However, it had the disadvantages of long limbs, thin skin, weak resistance to the sun and skin diseases, and high feeding conditions. In China, there were different breeds of Landrace pigs, such as the British, French, Belgian, and American breeds. They were mainly divided into the New American, Canary, French, and Danian breeds. Different breeds had their own characteristics. For example, the New American breeds had good body shape, strong limbs, and strong disease resistance. In the National Livestock and Pork Genetic Resource Species List published in May 2020, Landrace pigs belong to traditional livestock and poultry. Changbai's novel is equally exciting.
