Common Name: Pig, Swine
Latin Name: Sus scrofa
Classification: Kingdom: Animalia; Phylum: Chordata; Class: Mammalia; Order: Artiodactyla; Family: Suidae; Genus: Sus; Species: Sus scrofa

Subspecies: There are multiple subspecies of Sus scrofa, including the wild boar (Sus scrofa scrofa) and the domestic pig (Sus scrofa domesticus).
Life cycle: Pigs typically have a lifespan of 10-15 years, with wild boars potentially having a shorter lifespan.
Distribution: Pigs can be found in various habitats across Europe, Asia, Africa, and Oceania, such as forests, grasslands, and agricultural fields. Domestic pigs are raised globally and are one of the essential livestock species.

Genome size: The pig genome is approximately 2.8 Gb (gigabase pairs) in size.
Chromosome number: Pigs have 19 pairs of autosomes and one pair of sex chromosomes, totaling 38 chromosomes.
Gene number: The pig genome is predicted to contain around 20,000-25,000 genes.
Known significant genes: Important genes in the pig genome include those related to growth, reproduction, and disease resistance, such as growth hormone (GH), the protein kinase AMP-activated non-catalytic subunit gamma 3 (PRKAG3), and the toll-like receptor 4 (TLR4) for viral resistance. These genes have a significant impact on pig growth and development, production performance, and disease resistance.
