Effect of breed, finish weight and sex on pork meat and eating quality and fatty acid profile
Monday, 4 April 2011
By 2007 the terminal sire breed that was commonly used in Northern Ireland had changed from Landrace to Pietrain or Tempo due to the onset of Post Weaning Multi Systemic Wasting Syndrome (PMWS). A study was instigated which aimed to examine the production and carcass performance of pigs representative of these breeds. In addition, the meat and eating quality of pork from these pigs was investigated.

The economic and welfare impact of lameness in sows in England
Monday, 4 April 2011
Lameness in pigs is a major welfare concern and one of the most commonly reported reasons to premature culling of breeding sows.
Development of an Acute Phase Protein Index as an objective indicator of sub-clinical disease status in live pigs
Monday, 29 November 2010
Sustainable Livestock Production LINK Programme

This feasibility study has shown that sub-clinical infection in young pigs evokes APP responses, and that an APP Index has the potential to objectively assess the presence and extent of sub-clinical disease in pigs.

Evaluation Of Zeolite As A Binding Agent To Mitigate Ammonia Loss From Pig Slurry And Manure
Tuesday, 12 October 2010
The work reported here considered the use of zeolite as a binding agent to mitigate NH3 volatilisation from pig manure and slurry applied to soil. Zeolites are clay like minerals from sedimentary deposits. Zeolites selectively adsorb cations.

Assessment of Novel Sire Lines for Meat Quality Traits
Tuesday, 12 October 2010
The aim of this project was to investigate whether there is a significant difference in meat eating quality as assessed by shear force, drip loss and pH, between progeny sired by different sire lines crossed with the same dam line.

Evaluation of a PCR assay for Porcine Reproductive and Respiratory virus in oral fluids
Tuesday, 3 August 2010
Following reports from the US that oral fluids may prove a useful and convenient diagnostic measure of group disease status in pigs, the aim of this study was to investigate the potential of this methodology in the UK herd, using Porcine Reproductive and Respiratory Syndrome Virus (PRRSv) as the target pathogen.

Sustainable systems for management of the weaner pig through nutrition: NUTWEAN
Friday, 28 May 2010
NUTWEAN's aim was to develop sustainable
management systems for weaner pigs through nutrition, without input from antimicrobial growth promoters (AGP), whilst maximising use of home-grown cereals and oilseeds. Nutrition around weaning was modified through exploiting the potential of dietary components to enhance gut health and food intake.

Lighting for pig units
Friday, 21 May 2010
The behaviour of the progenitor species of the pig and the anatomy and physiology of the porcine eye suggest that the domesticated pig is best adapted for dim levels of natural light. This knowledge can therefore be used to specify lighting for domesticated pigs kept either indoors or outdoors. In general, English law is based on sound scientific evidence.

On farm epidemiology of major enteric diseases
Friday, 21 May 2010
The objective of this project was to achieve a better understanding of the transmission of diseases by vectors on pig farms by studying their role in the epidemiology and control of key diseases – Lawsonia, PCV 2b and Brachyspira.

Does the Rearing Environment affect the Incidence of Zoonotic Infections in Pigs?
Friday, 21 May 2010
Research partners: University of Leeds

Sponsors: BPEX, Yorkshire Agricultural Society

Project duration: 2006 - 2009

This project aimed to address the question of whether differences in rearing environment on pig farms can affect incidence of zoonotic infections in pigs.

Implementation of existing knowledge on tail biting by the development and evaluation of prevention and outbreak husbandry advisory tools
Tuesday, 30 March 2010
Whichever actions are tried, the key is to do something as soon as possible, before more tails are bitten, before lesions become more severe with infection setting in, and before more pigs develop the habit of biting tails. Whilst dealing with an outbreak it’s also worth considering what triggered the behaviour in that particular batch of pigs to help prevent it in the next batch.

Critical review of on–farm intervention strategies against Salmonella
Wednesday, 17 June 2009
The purposes of this study are to summarize the available scientific literature on the effectiveness of on-farm interventions against Salmonella, to evaluate existing diagnostic tests for Salmonella, and to review studies on the cost-benefits of single interventions or Salmonella control programs. A summary of the existing scientific evidence associated with antimicrobial resistance and Salmonella in swine is also provided.

Efficacy of some Disinfectant compounds against porcine bacterial pathogens
Wednesday, 17 June 2009
Seven chemical disinfectants were tested against 10 species of porcine bacterial pathogens that are common in UK pig units, using the British Standard method BS EN 1656:2000. A range of temperature conditions, two contact times and two levels of organic soiling were included.
The bacterial pathogens showed widely different susceptibilities to the different disinfectants and none of the compounds was universally effective.
