Stor variation i dødsårsag blandt økologiske pattegrise

Farlig start: Nye resultater viser, at de primære dødsårsager blandt øko-pattegrise er klemning og dødfødsel, men variationen er stor

Risk factors for piglet mortality in Danish organic sow herds

High piglet mortality is a considerable problem in Danish organic sow herds. The aim of this study was to determine causes of preweaning mortality and to identify risk factors for piglet mortality within the Danish organic pig production. A large-scale study was performed in nine commercial Danish organic sow herds during a one-year period. Data included recordings on piglet mortality in 6000 litters. Moreover, 3000 piglets were necropsied in order to determine the cause of death. The results indicates that it is possible to achieve a lower piglet mortality in the future and that the Danish organic pig production and a high piglet mortality is not inevitably synonymous

Flere dødsfødsler om sommeren i danske økologiske besætninger

I projektet ViPiglet viser nye resultater, at varme, kuldstørrelse samt lægnummer i kombination med huld er risikofaktorer for dødfødsler i den økologiske faremark

Potential risk factors for piglet mortality in Danish organic pig production

An on-going large scale study in nine medium-large sized Danish organic pig herds during one year from June 2014 until June 2015. Detailed mortality registrations on 6000 farrowings. Necropsies of 4000 piglets

VIPiglets – de første tal

Relationer mellem søernes læg nr., huld og halthed og dødeligheden. Størrelsen af de obducerede grise. Er der diagnoser som er mere sandsynlige at se hos små grise modsat store grise? Har man større eller mindre chance for at overleve hvis man er født ind i et stort eller lille kuld? Er der større dødlighed hos grise som havde mange dødfødte kuldsøskende? Hvornår i fravænningsperioden dør der flest grise ved klemning? Har klemte grise andre diagnoser? Er det altid de små grise der bliver klemte

Piglet mortality in Danish organic herds

Summary Preliminary results On farm mortality registrations – high mortality Hot summer in 2014! Necropsies Crushed piglets represent the largest group of diagnoses The majority of the crushed piglets had suckled before dying The majority of stillborn piglets die during the farrowin

Obduktioner af økologiske pattegrise

Om projektet: Hvad: Undersøge risikofaktorer for pattegrisedødelighed i den dansk økologisk svineproduktion Hvorfor: En estimeret dødelighed i fravænningsperioden på mellem 25 og 40 % er uholdbart både ud fra et økonomisk og dyrevelfærdsmæssigt synspunkt. Hvordan: 1. Detaljerede dødelighedes registreringer foretaget i 9 besætninger over en etårig periode 2. Obduktioner af et udvalg af døde pattegrise fra de 9 besætninge

Increase sustainability of organic pig production with more vital piglets

About every third piglet dies before weaning within the Danish organic pig production, making the organic piglet mortality higher, than what is seen in the conventional indoor production. The high piglet mortality is in conflict with both the idea of increased animal welfare and the organic principles. As most of the piglets die within the first days after farrowing, improving the thermal conditions around the time of farrowing is important, since the thermal environment in many cases may be a significant contributor to piglet death also for piglets that are categorized as crushed or starved to death. This paper describes a subproject under the larger Danish VIPiglets project with the overall aim to reduce piglet mortality in Danish organic pig production. The subproject described in this paper has three overall aims concerning 1) ways to improve the thermal environment around the time of farrowing 2) how the temperature and humidity inside the farrowing hut relate to piglet mortality 3) how temperature affects farrowing duration and inter birth interval. Studies concerning aim two and three are still ongoing and so no results are presented. In the study concerning aim one the average total litter size was 17 piglets and total piglet mortality was 31%. The study showed that providing sows with access to poplar trees (a shaded area) significantly affected paddock use compared to sows without a shaded area (control sows), by increasing the use of the paddock before farrowing and day zero and one post partum (pp) (F4,218=2.91, p<0.05) and the paddock use particularly increased at hot temperatures. Furthermore the sows with access to poplar were lying more when outside compared to controls (29 % vs 18 % respectively; F1,70=15.13, p<0.0005). In general the sows were seen lying more in the paddock at high temperature compared to low temperature particularly before farrowing, on day 0 and 1 pp and again after day 11 pp

Data i stakkevis om døde grise

Eksperter er i gang med at samle data fra 6.000 faringer og 4.000 obduktioner af døde pattegrise. Det gælder om at klarlægge hvornår i diegivningsperioden pattegrisene dør, og hvad de dør af. Der er tale om den hidtil største datamængde i Danmark om emnet

Identification of sow level risk factors on early piglet mortality in Danish organic sow herds during different seasons

The objective of this study was to identify season, litter size, sow parity and sow health as risk factors for still birth and early piglet mortality in Danish organic pig herds
