چکیده
Swine production is a highly scientific and specialized business in American agriculture. According to the Foreign Agricultural Statistics Web site, the total world hog numbers in 1999 were 762 million head. China ranks highest in the production of hogs, which amount to 422.5 million head. The European Community, which consist of France, Spain, Italy, West Germany, Belgium, Netherlands, Luxembourg, Denmark, Ireland, United Kingdom, Greece, and Portugal, ranks second in hog production with 122.8 million head. The U.S. ranks third with 62.2 million head. In the U.S., Iowa ranks first in hog production, while Texas ranks fifteenth. Hogs rank second only to cattle in total livestock production in the U.S. The per capita consumption of pork has remained fairly constant, but the human population has greatly increased. The increase in human population has caused swine production to increase through improved breeding, feeding, and management programs. Hog producers must select hogs to meet the needs of the current swine market.

Phylogenetic Relationships of the Mangalitsa Swine Breed Inferred from Mitochondrial DNA Variation
The Mangalitsa pig, a swine breed belonging to the protected gene fund of original and primitive animal breeds of the FAO (Food and Agriculture Organization), has been known to inhabit Romanian territories since the 19th century. The aim of this study was to compare the Mangalitsa breed with several European and Asiatic swine breeds in order to emphasize its uniqueness and to elucidate its orig...
متن کاملEffects of age on lipogenesis and lipolysis in lean and obese swine.
The effects of age on lipogenic and lipolytic activities in several breeds of swine were investigated. Females from a contemporary line and genetically selected populations of lean and obese pigs were utilized. Subcutaneous adipose tissue samples were taken from the shoulder area of nonfasted animals at 28-day intervals from 3 to 6 months of age for determination of in vitro lipogenic, lipolyti...
متن کاملMitochondrial DNA sequence and phylogenetic evaluation of geographically disparate Sus scrofa breeds.
Next generation sequencing of mitochondrial DNA (mtDNA) facilitates studies into the metabolic characteristics of production animals and their relation to production traits. Sequence analysis of mtDNA from pure-bred swine with highly disparate production characteristics (Mangalica Blonde, Mangalica Swallow-bellied, Meishan, Turopolje, and Yorkshire) was initiated to evaluate the influence of mt...

Phylogenetic Analysis of the Swine Leukocyte Antigen-6 Gene Generated from Spleentissue of Korean Native Pig
This study was aimed to search genetic variants, to investigate phylogenetic relationships between pig breeds and to provide basic genetic information of Korean Native Pigs (KNP) using the variations of the Swine Leukocyte Antigen-6 (SLA-6) gene. Cloning of the Swine Leukocyte Antigen (SLA)-6 gene in the MHC non-classical region was performed with spleen tissues of Korean Native Pigs (KNP). Seq...
