Swine genetics and reproduction
The performance of pigs is the result of two influences: genetics and environment. Because the genetics of a pig plays an important role in its performance and meat quality, all pig producers should be familiar with the potential and application of genetic selection.
The genetic potential of pigs can have a major influence on the productivity and profitability of a pig enterprise. It is the combination of genetics, nutrition, health, environment and management that influences such factors as litter size, growth rates and carcass quality.
The reproductive herd is for the multiplication of maternal and paternal lines that are prized for economically valuable reproductive traits, or, traits that generate desirable offspring reliably. Typically, prized reproductive traits include litter size, particularly total number of pigs born, and pigs weaned, weight of the litter of piglets at birth and weaning, wean-to-estrus interval (WEI), and pigs per sow per year (PSY). In more recent years, length of time a sow remains productive in the herd (longevity or survivability) is increasing in priority for major genetic lines. These traits are prioritized due to the impact on value of the sow to the herd.
The efficacy of organic trace minerals in swine nutrition has not been adequately evaluated, particularly during the reproductive period. However, the research to date has generally used a combination of inorganic and organic mineral mixtures. This procedure does not evaluate either source independently and may be confounded further because both inorganic and organic trace minerals may be found in several forms. The bioavailability of each is influenced not only by its form but the...

Orders for breeding stock from Russia, worth £1 million to Yorkshire-based pig-breeding company ACMC and due to be shipped in September and November, have been placed in jeopardy as a result of the foot-and-mouth (FMD) outbreak, says the company. It also predicts severe financial upheaval for the pig industry as a whole. "Parts of the pig carcase which have little or no value on the home market are exported to the Far East. If this export market is closed, British pigmeat...

The creator of Dolly the sheep has called for farmers to take up cloning as a way of producing cheap food. Professor Keith Campbell believes the country's farms should be populated by superstrong, super-sized offspring of clones. The US expects to be eating clone-farmed burgers, pork and bacon within two years, and supporters of the method say Europe must follow suit. A US clone cow has already been born on a British farm for the first time, making Frankenstein Farming a...

Advances in swine productivity through genetic selection, management, health and nutritional strategies have resulted in reproductive performance once unimaginable. Feed efficiencies during the growing and finishing phase of production have improved in the range of 25% over the past 15 years (Fremaut, 2003). Sow reproductive efficiency has shown equal improvement and the biological potential of today’s modern, hyperprolific genotypes is truly staggering (Close and Cole, 2001; Johnson, 2006;...

Prolificacy, in pigs, has increased substantially during the last 10 years after several decades of stagnation. Two main approaches have been followed in order to develop the so-called ‘hyperprolific’ lines of pigs. The first approach is based on crossbreeding between occidental and Chinese breeds, known for their high litter size. In this case, the litter size improvement is due mainly to a higher embryo survival rather than an increase in ovulation rate. However, the poor meat quality...
