About Volume 63
A group of three papers explores endemic diseases. Wallgren catalogues the transition of PMWS in Sweden from an exotic disease to an endemic one. These transitions are al1 too familiar in the field, but are rarely explored and described in print. The theme is continued by Wieland and her co-authors who have studied PMWS in England and its effects on endemic diseases. PMWS has been such a severe disease in the United Kingdom since 1999/2000 that some endemic diseases had almost been forgotten but are now being recognised once· more as PMWS is brought under control by the use of efficient vaccines. Finally, Sanchez - Vásquez examines the possible causes of enzootic pneumonia like lesions and pleurisy in slaughtered British pigs. This study has arisen following the detailed recording of slaughter pig lesions in relation to farm of origin, and is particularly pertinent as other countries do not appear to have the same levels of these as the UK.The general section comprises papers on antimicrobial concentrations in plasma and lung in bacterial lung infections. There is relatively little known about the distribution of these active molecules in the various compartments of the lung and their interaction with organisms at the site of infection, so this is a welcome contribution to the body of knowledge. Respiratory disease remains one of the major causes of mortality and 10wered production in the UK, and any new information which allows us to manage and control respiratory disease more successfully and more efficiently is very welcome. The second paper provides a view of the reasons why salmonella infection in pigs is still a problem in the UK pig herd, and helps to explain why eradication has not be en accomplished. Reducing the level of salmonella contamination is a major challenge to both pig keeper and veterinary surgeon. To date, little progress has be en achieved but over the next few years there must be a significant reduction in contamination levels and all possible avenues for achieving this goal must be explored.
The research papers address basic nutrition and gut physiology in the weaner in two ways; firstly by examining the effects on feed intake and gut structure of organic acids and phytase in the diet (Carroll and Miller) and secondly by evaluating its health following treatment with oral toltrazuril, a coccidiostat. This paper quantifies and helps explain the observed improvements in growth seen when coccidia are controlled in sucking piglets. The study of Mycoplasma Ilyorllillis by Nicholas and Rosales represents a re-examination of an organism which is ubiquitous and which was shown by Gois in the 1970s to cause pleurisy. This organism has re-emerged as a major pathogen on some farms and so this study is very timely. The final paper in this section, by Ruiz and co-authors, addresses one of the practical problems of artificial insemination, not just the number of sperm, but the concentration and volume effects on sow fertility, which have been the subject of empirical recommendations for many years. More and more pig farms in the UK are moving over to 100% artificial insemination and the more we can learn and understand about semen and artificial insemination practices the more successful sow reproduction performance will become. The case report by Donadeu and her co-authors describes a method of eradication of enzootic pneumonia which reduces the interruption in production caused by partial or complete depopulation. The final paper is about a single pig and serves to remind the readership that the pig can be an individual and that careful examination of individuals can contribute to our knowledge of the species. With pig keeping becoming an increasingly popular pastime amongst members of the general public it is important that pig veterinarians and general practitioners remain aware of potential individual pig problems. Twomey and his co-authors are to be commended.
The selection of papers in this Volume of The Pig Journal provides a useful addition to our knowledge of the pig.
