I compiled this post after so many questions been asked about the types of breed of pigs that are reared in Nigeria, so here are some breeds .........................
The Large White, also known as the English Large White, is a breed of domestic pig originating in Yorkshire, hence also known as the Yorkshire pig. First recognized in 1868, the breed is the progenitor of the American Yorkshire (or simply Yorkshire) in North America.
[1] The Large White is one of the most numerous of all pig breeds, widely used in crossbreeding for intensive pig farming around the world.
[2] True to its name the breed is a big white-skinned pig, with erect ears and a dished face. It was originally developed as an outdoor breed, but today it is one of those favored by commercial pig breeders, lending uniformity to pigs produced for meat on a large scale.

The American Landrace is a medium to large breed of domestic pig, white in colour, with long bodies, fine hair, long snouts, and heavy, drooping ears. They are bred for pork production. The American Landrace derives from the Danish Landrace of 1895 Danish origin. In the early 1930s, the United States Department of Agriculture (USDA) entered into an agreement with the Ministry of Foreign Affairs in Denmark for the purchase of 24 Danish Landrace to be used for swine research studies, with the stipulation that they would not be commercially propagated as a pure breed. Landrace were subsequently used in numerous comparisons with American breeds. In 1949, upon USDA petition, Denmark released the United States from its breeding restrictions. The American Landrace Association was formed in 1950, and the American Landrace breed was established from outcrosses with Norwegian and Swedish breeding stock.

the duroc pig, In 1812, early "Red Hogs" were bred in New York and New Jersey. They were large in size. Large litters and the ability to grow quickly were characteristics Durocs possessed from the beginning. The foundation that formed today's "Duroc" was comprised of Red Durocs from New York and Jersey Reds from New Jersey.
In 1823, Isaac Frink of Milton in Saratoga County, New York, obtained from Harry Kelsey of Florida New York, a red boar, one of a litter of ten pigs. The sire and dam of these pigs were probably imported from England. Kelsey owned a famous trotting stallion named Duroc, so Frink named his red boar in honour of the horse. This boar was known for his smoothness and carcase quality.
His progeny continued the Duroc name and many of them inherited his colour, quick growth and maturity, deep body, broad ham and shoulder, and quiet disposition. The Duroc was smaller than the Jersey Red, with finer bones and better carcase quality. Beginning in the early 1860s, Durocs were made from a systematic blending of the two very different strains.
The first organization for the purpose of recording, improving, and promoting Red Hogs was the American Duroc-Jersey Association, which was established in 1883. At the 1893 Chicago World's Fair, Durocs gained wide popularity at the first successful Duroc Hog Show.
The Duroc made two attempts to gain a foothold in this country; the first in the early 70s was not very successful, although some of those pigs were exported on to Denmark. They were re- imported in the early 80s and a comprehensive trial was undertaken by the MLC to assess the merits of the Duroc as a terminal sire. It was found that in the British skin-on fresh pork market the Duroc could not be used as a purebred but only as component of a crossbred boar. The development of Duroc crossbred boars produced large numbers of crossbred gilts. A market was found for these due to a resurgence of interest in outdoor pig production. This has resulted in breeding and selection programmes for the British Duroc focusing on female line characteristics rather than the traditional terminal sire traits associated with the breed. The Duroc has now found a special niche in the British industry and a unique British version of the breed has been developed.
Their thick auburn winter coat and hard skin allows them to survive the cold and wet of the British winter. This coat moults out in summer to leave the pig looking almost bald, but as a consequence it can cope with hot dry summers equally well. All purebred Durocs are red in colour and the development of a so-called “White Duroc” has only been achieved by crossbreeding with a white breed.
Its tenacity in looking after its young combined with its docility between times makes it an ideal candidate for an outdoor pig, either as a dam or sire line, and its succulence and heavy muscling makes it very suitable for anything from light pork to heavy hog production.
Further research funded by the MLC has investigated the Duroc’s claim to produce high levels of tenderness. This has led to a recommendation to include Duroc genetics as part of the meat quality Blueprint.

Infectious Bursal Disease (Gumboro)
Infectious bursal disease is an acute, highly
contagious viral disease of young chickens. It is
most often found in highly concentrated poultry
producing areas. It causes marked morbidity
and mortality in affected flocks. Although the
disease causes severe losses, its affect on
reducing the bird's ability to develop immunity
to other diseases may be the most serious effect
produced by this disease.
The transmission or spread of the disease can
occur by direct contact (bird to bird),
contaminated litter and feces, caretaker,
contaminated air, equipment, feed, servicemen
and possible insects and wild birds. It is
extremely contagious.
Birds have ruffled feathers, a slight tremor at
onset of the disease, strained defecation, loss of
appetite and are dehydrated. Affected birds
have a tendency to sit and when forced to move,
have an unsteady gait. Vent picking is common
and a whitish diarrhea frequently develops. A
sudden rise in body temperature is followed by a
drop to subnormal temperature, prostration and
death. Birds surviving the initial infection will
recover rapidly within two weeks.
Postmortem lesions include dehydration and
changes in the bursa, skeletal muscle, liver and
kidneys. All affected birds have bursal changes
characterized by swelling, change in shape
(oblong), color (pink, yellow, red, black) and the
formation of a gelatinous film around the bursa.
Within a few days the bursa shrinks to half its
normal size or smaller.
Diagnosis of infectious bursal disease is based on
flock history and postmortem lesions. Laboratory
procedures may be used to substantiate the
diagnosis.
Vaccines are available but must be carefully
used. If given correctly, good immunity can be
developed. There is no specific treatment for
infectious bursal disease and indiscriminate
medication with certain drugs may severely
aggravate mortality. Supportive measures such
as increasing heat, ventilation and water
consumption are beneficial.
