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.

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...

The challenge to get sows and gilts to cycle and then maintain subsequent pregnancy occurs every year. But with vets in some parts of the UK reporting increased incidence of reduced appetite resulting in failure to come on heat and, therefore, increased weaning to service intervals, producers are likely to be looking at ways of improving sow fertility. BPEX AI programme manager Angela Cliff says there is no definite pattern with infertility, so it is vital to provide sows with the...

Tim S Rymer, JSR Genetics, reflects on his recent trip to China and the industry he witnessed.
The size and scale of the Chinese pig industry takes your breath away, 1.3 billion consumers eat their way through 600 million slaughter pigs, produced from 50 million sows - 50 % of the world's pig population. But the size and scale of the industry is not enough to guarantee a profit, as today most pig producers are emerging from a period of sustained losses.
The Chinese pig market appears to...

With new technologies for artificial insemination, a key question is often "What is the correct volume and concentration of a semen dose to achieve optimal performance?"
For AI to be successful, the physical displacement of the uterus is crucial for effective transport of the semen to the oviduct. For this to occur, it is essential to mimic the naturally large volume of a boar ejaculate. Scientific...

A change in service house design to limit sows contact with boars immediately after weaning may help improve breeding herd productivity, new research has shown.
While weaned sows are generally given partial access to boars to encourage the 'standing response' as an indicator of oestrus, continual contact may not be helpful, since the sows become used to the boars. This can lead to faulty heat detection and therefore inaccurate timing of insemination, says ACMC animal scientist, Lucy...
