The difference between Landrace and Duroc
The Landrace was native to Denmark, formerly known as Landrise. Its entire body was white, its head was narrow and long, its ears inclined forward, and its body length was longer than that of ordinary pigs. It had 1 to 2 more cervical vertebrae than ordinary pigs, a shallow chest, a flat or slightly arched back, plump thighs, and well-developed buttocks. Each litter had 10 to 12 litters. The newborn piglet weighed 1,000 - 1.5 kg, and 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, weak resistance to the sun and skin diseases, and high feeding conditions. Duroc pigs were produced in the United States. Their fur was brownish-red (there were also golden to dark brown, with cherry red being the most popular. Black spots might appear on the skin, but black or white hair was not allowed on the body). Their heads were of moderate size, their faces were slightly sunken, their mouths were short and straight, and their ears were medium-sized and slightly inclined forward. Their backs and waists were straight, and their abdominal lines were straight. Their hind legs and buttocks were well-developed, their limbs were thick and strong, and their hooves were black and mostly upright. There were six pairs of effective papilles, which were arranged evenly and neatly. Adult Duroc boars weighed 300 - 350kg, and adult sows weighed 250 - 300kg. They were small in size but compact in structure. Duroc pigs could not only be used for slaughtering meat, but also for breed improvement. They were a lean-type pig breed. There were differences between the two in terms of origin, appearance, weight, reproductive performance, and advantages and disadvantages. Changbai's novel is equally exciting.

Compared to the Landrace Duroc
Landrace pigs are native to Denmark, Large White pigs are native to the United Kingdom, and Duroc pigs are native to the United States. ** 1. Appearance ** 1. ** Long White Pig ** - Its entire body was white, its head was long and narrow, its waist was slender, and its spine was two more segments than that of ordinary pigs. - There were two types of eyeballs: sky blue (jade eyes) and gray brown. The neck was slender, the shoulders were plump, the buttocks were plump, the limbs were slender, the abdomen was flat and slender, and there were more than seven pairs of papillions. Occasionally, there were green spots. 2. ** Big White Pig ** - It was also white all over and was a world-famous lean-type pig breed, but it did not have the unique characteristics of the Landrace, such as a slender waist and many vertebrae, which were particularly distinct from other pig breeds. 3. ** Duroc Pig ** - Its fur was brownish-red (clearly different from the white of Landrace and Great White), and its body was muscular and had an excellent skeletal structure. ** 2. Production performance ** 1. ** Long White Pig ** - Fast growth and development, high feed utilization rate, and more lean meat. The daily weight gain could reach 800 - 900 grams, the lean meat rate could reach 68%, and the specialized maternal line could give birth to up to 13 heads. The production performance of different breeds of Landrace pigs was different. For example, the Landrace sows of the Canada-series, Dan-series and French-series had a large number of litters, and the number of live litters could reach more than 12. The American and Canada-series Landrace boars had excellent growth performance, and the age of 100 kg was only about 147 days. The New American Landrace had a strong physique, excellent skeletal structure, obvious double-muscled buttocks, plump hindquarters, thick limbs, average nutritional requirements, and obvious crossbreeding advantage. The Landrace was long, with dumbbell-shaped buttocks, thick limbs, high hanging hoofs from the ground, ears completely covering the forehead, high reproductive performance, fast growth speed, thick limbs and hoofs, and even performance. Dan-type Landrace pigs had delicate limbs. They had a sense of weight when they walked and swayed. Their backs were wide and flat, and their ears leaned forward. They had a long pregnancy period, and they had more limb and hoof diseases. They had a higher demand for nutrition and were very adaptable. - Landrace sows had a long lifespan, had more farrowing, and gained more weight on the market; they were more docile in the delivery room (good maternal nature); the quality of weaned pigs was good, and the weaning was heavy and uniform; compared with other breeds, the mortality rate of sows was halved or less; the better body condition and weight of sows at the time of elimination meant the added value at the time of slaughter. 2. ** Big White Pig ** - high feed conversion rate and slaughter rate, and strong adaptability. Large number of teats, good quality, even spacing, no blind teats; good motherhood, mild, large weight and large number of piglets; long service life, more litter in a lifetime, large weight on the market; insisting on lean meat growth traits breeding, commercial pigs have excellent lean meat growth performance; compared with other breeds, the loss is halved or less; better sow conditions and slaughtering weight mean the added value at slaughter. 3. ** Duroc Pig ** - It was originally a fat type pig, but it was later improved to a lean type pig. It was one of the most famous lean type pigs in the world. Excellent body shape and skeletal structure (tall/long/muscular), stronger limbs and hooves, able to withstand heavy pressure (long service life); Good meat-making performance, able to maintain growth under high pressure or disease environments (disease resistance and adversity resistance breeding, high survival rate of offspring); Selection based on commodity group testing increased the rapid transmission of pure excellent genes to the commodity group level. ** 3. Function in the hybrid system ** 1. ** Long White Pig ** - It could be used for pure breeding to establish high-quality basic sows, and it could also be used for crossbreeding to improve existing pig breeds. It could produce dual sows when crossed with large white pigs, and it played an important role in the crossbreeding system of pigs. 2. ** Big White Pig ** - As a world-famous lean-type pig breed, it could pass on its excellent traits (such as reproductive performance, lean growth performance, etc.) to its offspring in the crossbreeding system. It was an important parent for crossbreeding. 3. ** Duroc Pig ** - In the three-way hybrid system, Duroc pigs were often used as the terminal male parent. Their excellent growth performance, body shape, lean meat percentage and other traits could significantly improve the quality of crossbred offspring. At present, the commercial pig production in China is mainly the three-way hybrid breed of Duroc, Landrace and Large White. 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 Changbai and Duroc
The main differences between Landrace, Large White, and Duroc pigs were as follows: ** 1. Origin ** 1. ** Long White Pig ** - It was produced in Denmark and was bred from the cross between the Yorkshires and the Danes. 2. ** Big White Pig ** - It originated from the United Kingdom. Due to its wide distribution in the world, different countries formed different families after selection, such as the British family, the French family, etc. 3. ** Duroc Pig ** - It is produced in the northeastern United States. Its main parents are the Duroc of New York and the jersey red of New jersey. ** 2. Appearance ** 1. ** Long White Pig ** - The whole body was white, the head was narrow and long, the ears were inclined forward, the body was long, there were 1 - 2 more vertebrae than the average pig, the chest was shallow, the back was flat or slightly arched, the thighs were full, and the buttocks were developed. 2. ** Big White Pig ** - The whole body is covered in white hair, but there are occasional small dark spots on the forehead. The ears are of moderate size and upright. The mouth is straight, the face is flat or slightly concave, the head is of medium size, the lower jaw is occasionally drooping, the chest is wide, the back and waist are straight, the abdomen is well developed but not drooping, the legs and buttocks are muscular, and the limbs are thick and strong. The whole body shows a "rectangular" shape. 3. ** Duroc Pig ** - The fur color was brownish-red, but there were also golden to dark brown. Cherry red was the most popular. Black spots might appear on the skin, but black or white hair was not allowed on the body. The ears were medium-sized and slightly drooping forward. The back and waist of an adult pig were slightly arched, the muscles on the back were full, and the limbs were thick. ** 3. Production performance ** 1. ** Long White Pig ** - The growth and development were fast, and the feed utilization rate was high. Each litter had 10 - 12 pigs. The newborn piglet weighed 1 - 1.5 kg, and the adult boar weighed more than 250 kg. The meat quality was good, but its long limbs were weak, its skin was thin, and its resistance to the sun and skin diseases was weak. It required high feeding conditions. 2. ** Big White Pig ** - It had a large body, strong reproductive ability, high feed conversion rate, high slaughter rate, and strong adaptability. The average number of piglets in a litter was usually more than 10. The back fat of 100 kg was usually no more than 20 mm, and the growth speed was fast. It could usually reach 100 kg in 150 - 155 days after birth, and the lean meat percentage of the carcass could usually reach 65%. 3. ** Duroc Pig ** - As a meat-type breed, the average 158-day-old live weight of the growing-finishing pig was 95 - 100kg, the daily gain was 760g, the feed conversion ratio was 2.8 - 3.0: 1, and the carcass lean meat percentage was 60 - 65%. Sows had high fertility and good maternal instincts. Primiparous sows gave birth to about 9 sows with an average birth weight of 1.20kg. Multiparous sows gave birth to about 10 sows with an average birth weight of 1.30kg. Boars weighed 340 - 450kg and had a body length of 160 + 6.0 cm, while adult sows weighed 360 - 390kg and had a body length of 157.9 + 4.3 cm. The gilts showed their first estrus at 6 - 7 months of age and began mating at 9 months of age. ** 4. In terms of roles in the hybrid system ** 1. ** Long White Pig ** - It can be used as an important maternal or paternal breed in the hybrid system. 2. ** Big White Pig ** - Due to its strong reproductive ability and other characteristics, it was often used as a maternal or paternal breed in the hybrid system. Through the use of matching pig technology, it could be divided into two types, paternal and maternal. 3. ** Duroc Pig ** - It was mostly used as the paternal line of crossbred pigs. When it was used to improve local breeds, it had a significant hybrid advantage as a terminal paternal line. Changbai's novel is equally exciting. Everyone is welcome to click and read it!
