Great White Pig
Pig breeding veteran drivers know that the big white pig and the long white pig are both world-famous pig breeds.
The Great White Pig, also known as Yorkshire, is native to Yorkshire and its surrounding areas in northern England. Due to the strong reproductive capacity of large white pigs, feed conversion rate and slaughter rate, many countries have introduced and used to hybridize and improve local pig breeds, and achieved good results. Now many countries have more or less their bloodlines. For example, Hubei White Pig, Shanghai White Pig, Former Soviet Union Great White Pig and so on. Even the long white pig was introduced from the United Kingdom by Denmark and improved and bred with the local native breed of white pig.
The long white pig, formerly known as the Landres pig, is produced in Denmark and is raised in large quantities in major pig-raising countries around the world. Since 1964, China has been introduced from Sweden, the Netherlands, Denmark, the United States, Japan, and the United Kingdom, because of its particularly long body shape and white coat color, it is called "long white pig".

<h1 class="pgc-h-arrow-right" >2, variety characteristics</h1>
The great white pig is an ideal lean pig breed, with tight meat, less fat, thick limbs, strong physique, strong fecundity and lactation, and is not prone to stress response to the environment. At present, domestic large-scale pig farms are mostly used for mothers.
The body of the long white pig is streamlined, the lean meat rate is high, the reproductive performance is good, and the lactation is high. The disadvantage of this pig breed is that the limbs, especially the hind limbs, are relatively weak, and stress disorder may occur in poor environments, so it is not as good as the great white pig as a mother.
<h1 class="pgc-h-arrow-right" >3, production performance</h1>
The initial love period of the great white sow is 6 months, the weight of 7-8 months old is 110 kg, the number of litters is 11-12; the average daily weight gain is more than 820g, the ratio of feed to meat is less than 2.7, the lean meat rate is 64%, and the weight of 165-168 days old can reach 100 kg.
The first love period of the long white sow is 6-7 months, the weight of the 8-month-old is 110 kg, and the number of litters is 11; the average daily weight gain is more than 770g, and the ratio of feed to meat is less than 2.7. The lean meat rate is more than 65%, and the weight of 170-173 days old reaches 100 kg.
