Welcome to this week's newsletter

Editorial – Focus on Research

Researchers at the Institute for Animal Health (IAH) and collaborators at the Jenner Institute at the University of Oxford in the UK, have discovered why some vaccines are not as effective at stimulating an immune response as hoped and have investigated ways in which improvements could be made.

The research was led at IAH by Dr Jayne Hope (who is now based at The Roslin Institute, University of Edinburgh), Dr Efrain Guzman and Dr Bryan Charleston. The work was published last week in the journal, Vaccine.

Dr Charleston said: "We knew that sometimes even when we know a bacteria or virus well, it has been a struggle to make effective vaccines against certain diseases. We discovered that dendritic cells – a type of immune cell – are activated better by some vaccines than others.

"There are a lot of human and animal diseases that we would like better vaccines for but until now we haven't been able to find a good reason why, for example, the BCG vaccine against tuberculosis isn't always effective but the bovine herpes virus vaccine is extremely efficient at establishing long–term immunity."

The study focussed on the BCG vaccine that has been used against tuberculosis in humans and animals and which is known to have variable efficacy, but this discovery is important for developing new vaccines against many different diseases caused by viruses as well as bacteria.

A three-year feeding study has shown no adverse health effects in pigs fed genetically modified (GM) maize.

By coincidence, also in the UK, research carried out by pig breeding company, PIC, into the effect of semen age on reproductive performance in AI has seen a surprising result – that fresh semen is not necessarily best.

In a test to quantify the effect of the storage of semen on reproductive performance, the research team found that semen age does affect fertility but 'fresh' was not best.

The researchers are now questioning whether this is a semen effect – capacitation – or the processes sperm pass through to achieve fertilisation.

The company's supply chain manager commented that the research needs to include more information on the motility of the sperm, which, it has been discovered, does not necessarily mean greater fertility.

Now, PIC has a range of new tests and studies it is to conduct to gain more clarity and information about the results of the trials that have already been conducted.

Another genetics company, Topigs has announced its introduction of the Nador concept, which allows the possibility to select and use finisher boars that produce offspring with 40 per cent less boar taint.

In Canada, optimism among pig producers is on the rise. In 2011, three–quarters of hog producers (75 per cent) agreed that their farm or business will be better off five years from now.

Also in Canada, an associate professor at the Western College of Veterinary Medicine is encouraging pork producers to step up their focus on biosecurity to guard against the introduction of swine dysentery.

The Russian government has approved a reduction in meat import quotas for this year. Pork imports will decrease by 14 per cent – from 500,000 tonnes in 2011 to 430,000 tonnes this year.

And finally, nine new outbreaks of African swine fever (ASF) have been reported in South Africa in the last week. There is an unconfirmed report of a new outbreak of ASF in the Krasnodar region of Russia, and testing has been stepped up in the Ulyanovsk region.

We have 6 new features this week:

Outlook for the Irish Pig Sector in 2012
Over the last two years, the Irish pig industry has experienced the lowest profitability in more than a generation, according to Michael McKeon from Teagasc's Pig Development Department in his outlook for pigs in 2011/12.
Reducing Food-borne Illness: Gut Health
Genes and genetic pathways involved in the intestinal health of chickens and pigs are described and genome-wide prediction tools for intestinal health are defined in the final scientific report from the EU group, Sustainable Animal Breeding (SABRE) subtitled 'Cutting Edge Genomics for Sustainable Animal Breeding'.
One–Night Downtime Period Prevents Spread of PRRS Virus and M hyo by Personnel and Fomites
Basic biosecurity measures prevented the spread of porcine reproductive and respiratory syndrome virus (PRRSV) and Mycoplasma hyopneumoniae (M hyo) between pig herds by workers and fomites such as tools, according to researchers based in Minnesota, US. Extended downtimes did not reduce the spread of infection in their study, however.
Exploring Breeding Opportunities for Reduced Thermal Sensitivity of Feed Intake in the Lactating Sow
Despite carrying out their research on sows in climate-controlled houses, scientists in the Netherlands and Australia found variable effects of temperature on lactation feed intake, and there was an interaction between temperature and humidity. Average heritability for feed intake during lactation was 0.29.
Epidemiology and Control of Porcine Circovirus Diseases with Focus on Postweaning Multisystemic Wasting Syndrome
A review of the epidemiology and control of porcine circovirus (PCV) diseases by Poul Baekbo of the Danish Agriculture & Food Council and co-authors, presented at the International Symposium on Emerging and Re-Emerging Diseases in Pigs in 2011.
Denagard Performance - Issue 7 - Ileitis in vitro studies
In vitro studies show that L. intracellularis, the cause of ileitis, is sensitive to Denagard®.

New Head of Marketing for BPEX
UK - BPEX has appointed a new Head of Marketing to replace Chris Lamb who is retiring at the end of February after more than 20 years in the industry.
PIC Opens New AI Research Centre
UK - Pig breeding company PIC opened a gene technology research centre in the UK on Tuesday – believed to be the first of its type in the UK and probably in Europe.
BPEX Launches Revamped Website
UK - The BPEX website has been given a makeover to make it easier to navigate around the vast amount of information it contains.
US Hog Margins
US - Margins started 2012 off on a strong note, improving noticeably since the end of the year, writes Doug Lenhart.
Improving AI to Improve Commercial Pig Herd
UK - Fresh work on the study of porcine semen production could go a long way to improving the commercial pig herd in the UK, writes ThePigSite editor in chief, Chris Harris.
Less Boar Taint with TOPIGS Nador Concept
GERMANY & NETHERLANDS - TOPIGS introduces the Nador concept. With Nador it is possible to select and use finisher boars that produce offspring with 40 per cent less boar taint. With this innovation one of the challenges of producing with non-castrated male finishers is minimized. TOPIGS is the first breeding company that offers this solution for boar taint.
Research into AI Semen Age and Fertility
UK - Research carried out by pig breeding company PIC in the UK into the effect of semen age on reproductive performance in AI has seen a surprising result - that fresh is not necessarily best, writes ThePigSite Editor in Chief Chris Harris.
