A field intervention and 17 months’ monitoring of pig herd dynamics in seven villages in Northern Laos was conducted. The collected data show for the first time herd dynamics based on quantitative data. They show that dynamics follow a regular cyclic pattern based on the general farm management approach applied by farmers, which lacks a specific pig management focus. Interventions aimed at improving animal management and nutrition were far less successful than envisioned but revealed major conflicts in perception between implementers and farmers. Farmers did not shift their focus to pig production as major income-generating activity as envisioned by implementers. Nevertheless, despite only partially improved systems, farrowing and animal growth rates were increased among committed farmers, whereas death rates have decreased. However, our quantitative data show a significant number of constraints reflected in the way how animals enter, pass through and leave smallholder production systems. Disease and disease prevention, as well as animal feeding are the two dominant hindrances to improved production. Both these obstacles are rather related to a lack of focus on animal production and therefore animal requirements than to an inherent lack of understanding. To increase interest though, poor income opportunities due to lacking market opportunities will have to be tackled. However, even with an incomplete transition from a traditional to an improved system, overall production increased by 600% in committed farmers with an about equivalent increase in income from this activity, showing that current systems leave massive scope for improvement if perceptions and other external obstacles such as access to inputs and markets can be overcome.

Discriminatory Index

SUMMARYFor epidemiological investigations of the most common and non-host-adaptedSalmonellaserotypes, such as Typhimurium, highly discriminatory approaches are essential. In the present study, we evaluated three genotyping methods; amplified fragment length polymorphism (AFLP), pulsed-field gel electrophoresis (PFGE) and repetitive palindromic extragenic–PCR (Rep–PCR) using 40 isolates. AFLP showed the highest discriminatory index (0·939), resolution and throughput. To determine clonality ofSalmonellaTyphimurium isolates and epidemiological relatedness in different commercial pig production units, we employed AFLP in combination with antimicrobial resistance pattern and phage typing.Salmonellaserovar Typhimurium isolates (n=196) obtained from a longitudinal study of 18 pig farms over a 3-year period were studied. Using this approach, 16 distinct clonal types were identified. We found two common multidrug- resistant patterns including AmCmStSuTe and AmKmStSuTe. Two commonly multidrug- resistant phage types that are of known public health importance, DT104 and DT193, were also common. AFLP differentiated distinct clones within DT104, a phage type previously reported to be clonal. Fourteen of the clonal types were unique to one of the two production systems, showing diversity between independent commercial pig production systems located in the same geographical area. Clonal types obtained from nursery farms and corresponding finishing units were, however, similar.

Abstract There is world-wide increasing interest in the consumption of unprocessed, natural food commodities including fresh (unpasteurised) milk and milk products. Consumers are actively seeking out raw milk, partly due to health reasons, but also for taste, freshness, closeness to the producer and to support local agriculture. The need for high levels of hygiene and safety in farms producing raw milk for direct consumption has long been recognised and has led to federal and industry-initiated systems for safe raw milk production. Raw milk producers in North America and Europe have demonstrated that raw milk, intended for direct consumption, can be produced safe and hygienic. The aim of this paper is to describe practices that have been developed for safe raw milk production. The German Vorzugsmilch is a federally regulated programme for legal raw milk production that was established already in the 1930s to provide raw milk with high hygienic standards controlled for zoonotic diseases to consumers. The Raw Milk Institute is a non-profit organisation established in California that has developed a voluntary safe raw milk programme in North America. RAWMI has developed a risk analysis and management system for raw milk dairy farmers to assist farmers in making individually tailored solutions for various production systems. In British Colombia, Canada, small herd share farms have employed good manufacturing practices, a risk management approach and performed monthly samples for pathogens and indicator bacteria to demonstrate safety and consistency. The major components of the raw milk systems applied, and the results of regular milk microbial indicator bacteria are presented. For the German system, the results from standard monthly pathogen tests are compared to zoonotic pathogen tests from other milk sources. The overall results indicate that raw milk can be produced with a high level of hygiene and safety in various systems.

Mycotoxins are secondary metabolites produced by fungi under certain stress periods (Smith and Seddon 1998). When ingested, mycotoxins cause insidious losses, ill thrift and reduced disease resistance. Zearalenone is known to cause hyperestrogesium in pigs and hence a reduction in fertility in both sows and boars can occur (Binder 2004). Certain mycotoxins such as zearalenone (ZEA) and deoxinivalenol (DON) are produced by fungi of the fusarium species on crops in the field. Fusarium pseudograminearum (Crown Rot) produces both DON and ZEA in decreasing levels up the tiller of winter cereals (Blaney et al. 1987). Most studies carried out so far analysed the occurrence of mycotoxins in the grain and less is known about the prevalence of mycotoxins in the straw of the crop. Housing of sows during gestation on straw is becoming a favoured production system due to environmental and public perception pressures. The intake of straw by weaners on straw based systems has been found to account for 11.5% of total feed intake (Barneveld et al. 2004), such that there could be a considerable risk for increased ingestion of mycotoxins in animals on straw based systems. The objective of this study was to investigate the occurrence of mycotoxins in straw used for deep litter in Australian deep litter pig production systems.
