Knowledge synthesis: Animal health and welfare in organic pig production - Final Report COREPIG

This report reviews the available information on the welfare of pigs when maintained according to organic standards in Europe. It begins by overviewing the populations of organic pigs in different countries at the time of writing (2007), the organic standards which govern their management and the systems in which they are typically kept. It then reviews for each stage in the production cycle (sows, suckling piglets, weaned pigs and fattening pigs) the available literature on health and welfare problems which might be experienced by the animals and the hazards which might give rise to these problems. Finally the report reviews the methods current available for the measurement of pig health and welfare and the extent to which monitoring systems currently exist in different countries, or might be developed. The information gathered in this review formed the basis for the subsequent development of tools for use in a HACCP based management and surveillance system for organic pig herds. These tools will assist the organic pig farmer to prevent selected pig diseases and welfare problems by monitoring and controlling the risk factors. Further details can be found on the COREPIG project website www.icrofs.org/coreorganic/corepig.htm

HACCP for Suckling Piglet Mortality

Deliverables of the COREPIG project are management tools based on the HACCP principle (Hazard Analysis Critical Control Points). These tools help farmers (in a farm specific way) to solve and prevent problems with endoparasites, reproduction and farrowing problems, weaning diarrhoea and suckling piglet mortality. They are available as Microsoft Excel® files. We recommend that the tools be used by the farmer together with the farm's advisor or veterinarian. Each tool contains instructions for use and consists of three parts: i) a questionnaire for the farmer, ii) a check list to be used in the barn and iii) the farm specific report

Corepig, final report of WP3: Development and evaluation of a HACCP based surveillance and management system

Organic farmer repeatedly face problems with suckling piglet mortality, weaning diarrhoea, en-doparasites and farrowing/reproduction. These problems are multifactorial, they are caused by many factors whereby the key factors often differ from farm to farm. Thus, it was the aim of the 3rd work package of Corepig to develop a management tool based on the HACCP (hazard anal-ysis critical control points) principle, which can be used by farmers, advisers and veterinarians to solve health problems on organic pig farms. Several teams of experts for organic pig production including advisers and researchers created four risk assessment protocols, one each for suckling piglet mortality, weaning diarrhoea, endo-parasites and farrowing/reproduction problems. As the lists of possible risk factors are long and complex, the assessment protocols were incorporated into semi-automated MS Excel® files. The tools were tested on 32 farms in Austria, Denmark, France and Germany, where risks for the four problem areas could but reduced on 72% of farms. Farmers as well as advisers acknowledged the HACCP based management tools as valuable helps for organic pig produc-tion. The revised tools and their descriptions can be downloaded from the project homepage at http://www.coreorganic.org/research/projects/corepig/index.html (to be launched 01.09.2011)

Sow body condition at weaning and reproduction performance in organic piglet production

The objective was to investigate the variation in backfat at weaning and its relations to reproduction results in organic sow herds in Denmark. The study included eight herds and 573 sows. The average backfat at weaning mean�13 mm; SD�4.2 mm) ranging from 10.5 to 17.3 mm among herds shows that it is possible to avoid poor body condition at weaning even with a lactation length of seven weeks or more. No main effect of backfat at weaning on reproduction performance was found, but the probability of a successful reproduction after weaning tended to decrease with decreasing backfat for first parity sows, whereas the opposite was the case for multiparous sows

Changes in back fat thickness during late gestation predict colostrum yield in sows

Directing protein and energy sources towards lactation is crucial to optimise milk production in sows but how this influences colostrum yield (CY) remains unknown. The aim of this study was to identify associations between CY and the sow’s use of nutrient resources. We included 37 sows in the study that were all housed, fed and managed similarly. Parity, back fat change (ΔBF), CY and performance parameters were measured. We obtained sow serum samples 3 to 4 days before farrowing and at D1 of lactation following overnight fasting. These were analysed for non-esterified fatty acids (NEFA), urea, creatinine, (iso) butyrylcarnitine (C4) and immunoglobulins G (IgG) and A (IgA). The colostrum samples collected 3, 6 and 24 h after the birth of the first piglet were analysed for their nutrient and immunoglobulins content. The technical parameters associated with CY were parity group (a; parities 1 to 3 =value 0 v. parities 4 to 7 =value 1) and ΔBF D85-D109 of gestation (mm) (b): CY (g) =4290–842a–113b. ( R2=0.41, P<0.001). The gestation length ( P<0.001) and the ΔBF between D109 and D1 of lactation (P=0.050) were identified as possible underlying factors of the parity group. The metabolic parameters associated with CY were C4 at 3 to 4 days before farrowing (a), and 10logC4 (b) and 10logNEFA (c) at D1 of lactation: CY ( g) =3582–1604a+1007b− 922c ( R2=0.39, P=0.001). The colostrum composition was independent of CY. The negative association between CY and ΔBF D85-D109 of gestation could not be further explained based on our data. Sows that were catabolic 1 week prior to farrowing seemed unable to produce colostrum to their full potential. This was especially the case for sows with parities 4 to 7, although they had a similar feed intake, litter birth weight and colostrum composition compared with parities 1 to 3 sows. In conclusion, this study showed that parity and the use of body fat and protein reserves during late gestation were associated with CY, indicating that proper management of the sow’s body condition during late gestation could optimise the intrinsic capacity of the sow’s CY

Mycoplasma suis infection in suckling pigs on a Belgian farm

Mycoplasma suis (formerly known as Eperythrozoon suis) is an epicellular bacterium that affects porcine red blood cells. M. suis infections occur worldwide and are associated with weakness and anemia in suckling and weaned pigs, and reproductive disorders in sows. The present field report describes the detection of M. suis in anemic piglets originating from a Belgian farrow-to-finish herd. The herd was experiencing increased piglet mortality (16%) in the farrowing unit and had a high percentage of repeat breeders (22%). A control program using antimicrobials and hygienic and sanitary measures significantly decreased the number of clinically anemic piglets and the mortality rate in the farrowing unit. However, it did not have any significant influence on the reproductive failure of the farm. The lack of a significant effect on reproductive failure was probably due to the circulation of porcine reproductive and respiratory syndrome virus (PRRSV) on the farm

Organic Pig Production in Europe - Health Management in Common Organic Pig Farming

Organic farmers in Europe have developed different housing systems for pigs based on the availability of land, soil characteristics, climate, tradition and national organic certification schemes. This guide gives an overview of the typical housing systems used for pigs in organic farming. It lists advantages and disadvantages of the different systems and provides relevant recommendations to farmers for health managment
