Can Mrs. Su keep the sow with the Landrace?
The offspring of Sutai sows and Landrace boars were called Inner Sanyuan Sows and Changtai Erza Sows. For rural free-range farmers, if they wanted to keep sows, they might be more inclined to choose sows born by Taihu Lake with Landrace or Large White. The average number of sows born by Changtai Yuan was more than 17. Although the offspring of the Sutai sow with the Landrace had certain advantages, such as faster growth and higher lean meat percentage, it was not clearly indicated that it was very suitable to be kept as a sow. Therefore, whether to keep it or not still needed to consider a variety of factors, such as the scale of breeding (whether it was free-range or large-scale breeding), the purpose of breeding (whether to pay attention to the number of litters, meat quality or other aspects), etc. Changbai's novel is equally exciting.

Is the reserve sow, White or Landrace, better?
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.

Which is better to be a sow, a big white pig or a Landrace pig?
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.

What breed of pig is Landrace?
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.

Which is bigger, Duroc or Landrace?
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.

Which grows faster, Landrace or Duroc?
Both Landrace and Duroc pigs were breeds that grew faster. Landrace pigs grew fast and had good feed utilization rates. Duroc pigs only needed 114 days to grow to 100 kg, and it took about 170 days for them to grow to 200 kg (100 kg). However, based on the available information, it was difficult to determine exactly who grew faster between Landrace and Duroc pigs because there was a lack of comparison data under the same feeding environment and feeding conditions.

The difference between Landrace and Large White
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.

What is the best breed of Landrace pigs?
The Ying-Rui line Landrace had a stronger adaptability, a stronger physique, and more litters, but the percentage of lean meat in the carcass was lower. The Danmark line Landrace had a poorer adaptability, a weaker physique, and less litters than the Ying-Rui line, but the percentage of lean meat in the carcass was higher. In China, there were mainly American, British, French, Belgian, New Danian and other breeds. The crossbred offspring of the American and New Danian breeds grew faster and had higher feed returns. The offspring of the Belgian breeds had better body shape and higher lean meat percentage. Different strains had their own advantages and disadvantages in terms of production performance. It was not easy to determine which strain was the best. It had to be selected according to specific breeding needs and production goals. For example, if one focused on adaptability and the number of litters, the Anglo-Swiss line might be more suitable; if one pursued lean meat rate, the Danmark line might be better; if one considered the growth rate and feed reward of crossbred offspring, the American or New Danian line might be better; if one focused on body shape and lean meat rate, the Belgian line was a good choice.
