An autonomous robot for feeding outdoor pigs Organic Eprints
Andersen, B.H.; Kristensen, E.K.; Jensen, H.F.; Persson, A.; Jørgensen, R.N.; Sørensen, C.G.; Jensen, K.; Pedersen, J.M..
The objective of this is to develop a rational feeding technique for outdoor pigs and at the same time improve the outdoor system with regard to environmental impact and health. For a rational and competitive free ranch system ensuring high animal welfare and low environmental strain automation is crucial.

Abstract – A large variety of methods has been proposed in the literature for microarray data analysis. The aim of this paper was to present techniques used by the EADGENE (European Animal Disease Genomics Network of Excellence) WP1.4 participants for data quality control,normalisation and statistical methods for the detection of differentially expressed genes in order to provide some more general data analysis guidelines. All the workshop participants were given a real data set obtained in an EADGENE funded microarray study looking at the geneexpression changes following artificial infection with two different mastitis causing bacteria:Escherichia coli and Staphylococcus aureus. It was reassuring to see that most of the teams found the same main...

Analysis of the real EADGENE data set : Multivariate approaches and post analysis Inra
Sorensen, P.; Bonnet, A.; Buitenhuis, B.; Closset, R.; Déjean, S.; Delmas, C.; Duval, M.; Glass, L.; Hedegaard, J.; Hornshoj, H.; Hulsegge, I.; Jaffrézic, F.; Jensen, K.; Jiang, L.; Koning, D.J.; Lê Cao, K.A.; Nie, H.; Petzl, W.; Pool, M.H.; Robert-Granié, C.; San Cristobal, M.; Lund, M.S.; Van Schothorst, E.M.; Schuberth, H.J.; Seyfert, H.M.; Tosser-Klopp, G.; Waddington, D.; Watson, M.; Yang, W.; Zerbe, H..
The aim of this paper was to describe, and when possible compare, the multivariate methods used by the participants in the EADGENE WP1.4 workshop. The first approach was for class discovery and class prediction using evidence from the data at hand. Several teams used hierarchical clustering (HC) or principal component analysis (PCA) to identify groups of differentially expressed genes with a similar expression pattern over time points and infective agent (E. coli or S. aureus). The main result from these analyses was that HC and PCA were able to separate tissue samples taken at 24 h following E. coli infection from the other samples. The second approach identified groups of differentially co-expressed genes, by identifying clusters of genes highly...

FeederAnt - An autonomous mobile unit feeding outdoor pigs Organic Eprints
Jørgensen, R.N.; Sørensen, C.G.; Jensen, H.F.; Andersen, B.H.; Kristensen, E.F.; Jensen, K.; Maagaard, J.; Persson, A..
Small robots and the concept of decentralized animal husbandry make it possible to renew the principles of organic agriculture. The farm animals will be able to use the same type of housing and are placed integrated with the fields. This is expected to achieve a better utilization of nutrients and a better survival rate for useful insects and micro organisms. The small fields are flexible and could fit to the variation in soil structure topography. This type of precision agriculture has the possibility of increasing biodiversity. The paper presents the concept of an autonomic feeding system for outdoor piglets. Initial results are presented using a remote controlled feeding unit (a prototype of the FeederAnt) to feed several pens with piglets. The...

Abstract – Microarray analyses have become an important tool in animal genomics. Whiletheir use is becoming widespread, there is still a lot of ongoing research regarding the analysis of microarray data. In the context of a European Network of Excellence, 31 researchers representing 14 research groups from 10 countries performed and discussed the statistical analysesof real and simulated 2-colour microarray data that were distributed among participants. The real data consisted of 48 microarrays from a disease challenge experiment in dairy cattle, whilethe simulated data consisted of 10 microarrays from a direct comparison of two treatments (dye-balanced). While there was broader agreement with regards to methods of microarray normalisation and significance...
