6Artificial Insemination in SwineEduardo Paulino da Costa 1 , Aurea Helena Assis da Costa 2,3 ,Gustavo Guerino Macedo 3 and Emílio César Martins Pereira 31 Federal University of Viçosa2 Germovet3 Post-graduation students from the first authorBrazil1. IntroductionThe world population is 6.4 billion people approximately and is constantly growing. In thiscontext, there is the expectation that it will reach 8.1 billion in 2030 and nine billion in 2050.In the next 25 years, this population growth will demand some 50% increase in foodproduction. So, the world will be required some 53% increase in meat production, thereforeelevating from 367 to 562 million tons. This will be necessary due the growth of thepopulation and the increase of the per capita consumption, which is foreseen to reach19.1Kg swine meat for inhabitant in 2030. So, the production of swine meat should present agrowth around 20%, therefore reaching 155 million tons (Roppa, 2006). This growth is reallyhappening, as considering that the world production of swine meat in 2010 reached 101million tons, with projection of 133 million for 2019 (ABIPECS, 2011).The increase of the productivity in the world swine confinement is happening along the lastdecades. According to data from ABIPECS (2011), China leads the world ranking byannually producing about 50 thousand tons of meat, as followed by the European Union,United States and Brazil (22,250, 10,052 and 3,170, respectively). This high productionbasically occurred by development and adoption of new technologies in practically all areas,such as genetics, nutrition, management, sanity and reproduction. Undoubtedly, in thereproduction area, the artificial insemination (AI) represents an enormous progress inproduction of swine. Since the beginning of the 70-ies, this technique provoked a greatimpact on increment of the swine production, especially in Europe and more recently inUSA (Gerrits et al., 2005).Initially, AI appeared in order to provide the genetic improvement of the animals and tosolve sanitary problems. However, a significant improvement in both productive andeconomical aspects were later observed, as making possible an acceleration in diffusion ofthe desirable characteristics of the reproducers with high genetic value. This occurred due toAI great potential in making possible the use of biotechnologies such as those related totechnology of the semen, preservation of embryos, and others.The intracervical insemination (ICAI) is most used in the technified farms. Under thepractical viewpoint, it is a simple and easily accomplished procedure. In this technique, thesemen is deposited in cervix and the spermatozoids are transported until the ampulla of theuterine tube, the place where fecundation occurs (Rath, 2002).
