The Large White is by far the most common breed in the world. In 1981 in England where registered 3.990 Great White pigs, thus placing it in the top pig breeds in their country of origin. Large Whites are distinguished by their appearance, very picturesque, raised ears, white-colored with pinkish skin. They were valued for the bacon production since the race came out. As the name suggests, it is characterized by the size .The breed is originally from Yorkshire Country, England, but it is difficult to determine their exact evolution.
The number of domestic pigs is about 961 millions of which 190 million in Europe and 483 million in China.
Fattening pigs is more cost-effective at a young age; feeding middle age pigs begins at 6 months and for the adult after 12 months or after the animal is removed from breeding. The fodder that enters their daily diet should be easily digestible, so it can be easily converted by the pig's stomach into substances that can be assimilated into the body and then transformed into meat
The best digestibility coefficient of feed is between 80-90% of the total quantity, and it is accomplished when the food given is based on barley and maize.
It has an elongated snout, a thick skin called rind and it is covered with stiff and rare hairs.
To facilitate their classification, pig breeds were divided into four groups:
- 1. mixed breeds, where we find the Large White, Landrace, Duroc.
- 2. meat breeds, which include the Pietrain, Landrace Belgian, Hampshire.
- 3. breeding races, includes the Meishan, Jianxing (Chinese breeds).
- 4. local breeds that are found predominantly in unfavorable areas, where raising conditions are poor.
Pigs of mixed breeds are good for both breeding and fattening , the meat pigs are bred almost exclusively for the carcass and the Chinese pigs from reproduction breeds offer the highest yields: between 14 and 17 piglets at one farrowing.
Almost every farmer knows that the pigsty must be free of rodents. Do not forget that the small mammals are responsible for transmitting many diseases, many of them fatal. So the most dangerous diseases that can affect pigs are: ascariasis, trichinosis, scabies or lice.
The Large White is regarded as a resistant breed, it can withstand climatic variations and of other surrounding factors. Its ability to cross and improve other breeds turned them into an important factor in commercial swine production. For decades they are known as preferred animals on the markets for pork and quality bacon. Their tendency to grow and not to have excess fat made them to be preferred where they're raised for small sizes, and also on the markets where there are bred to reach large sizes.
The Large Whites are known for excellent maternal instincts and high milk production. Not only lean and active, but also quite stable on their feet. They carry their considerable length with ease and grace. Their height, or legs length, help them stay active and have a long life. Although the Large White breed is originally created as an active and outdoor breed, it does well in confined or crowded spaces.
Sexual maturity is reached before the age of one year. The sow can even give birth to 15 piglets at the first birth. The gestation period and the frequency of the “ heat” state is about : 15 respectively 21 days. In the second “heat” period mating is recommended. After 12-16 hours, ie the next morning, after the so-called “acceptance reflex” develops (meaning that the female accepts the male to mount her), we can say that mating time comes. New breeders need to know that: the domestic sow is not violent and doesn't bite when defending the piglets, she just makes noise, but caution, there are still some exceptions.
A healthy sow, when mating at the optimal age and body weight, when well-kept and nourished properly, can produce piglets until the age of 6-7 years, during which she gives birth for about 8-10 times. Usually, sows are used more frequently for 4 to 8 calvings.
Factors that influence the growth of pigs:
Exogenous factors relate to: quantity, quality and mode of administration of feed, care conditions, breeding and fattening technology, transport options.
Endogenous factors are race, the breeding of animals, sex, prolificacy, nursing ability, number and weight of weaned piglets, fodder precocity and revaluation, health and endurance, slaughter yield and carcass quality. The gender also influences the meat production. Males, castrated or not give 8-10% more meat than females, but females give superior meat in terms of quality, and with less fat.
