In conclusion, ANI is an appropriate method for assessment of laying hen welfare on a large number of farms with different housing systems. The results of this study show that ANI is valid and sensitive enough to show differences in animal welfare between housing systems, whereas differences in welfare within housing systems cannot be shown. A significant negative correlation was found between ANI and ‘wing damage’ (from FCS). From the developer: DataThief III is a program to reverse engineer data points from a graph. The application is categorized as Business Tools. The latest setup package occupies 290 KB on disk. Our antivirus scan shows that this Mac download is clean. Significant positive correlations were found between ANI, on the one hand, and ‘movement’ and ‘comfort’, two factors from behavioural observations, on the other hand. DataThief 3.0 for Mac can be downloaded from our software library for free. This resulted in two factors for each method. Data from behavioural observations and FCS were reduced with principal factor analysis. Instantaneous scan sampling and continuous focal sampling were used to assess the time spent on different behaviours and the occurrence of event behaviours. Co-authored PROSPERO research planning documents, co-authored peer-reviewed publications. Coordinated a team in the review and data extraction process. During a 1-day visit on each farm, ANI was assessed, FCS was scored, and behavioural observations were performed. Conducted systematic review and data extraction for network meta analyses. ago Another tool that I have been using is Engauge Digitizer: I don't have experience with Datathief, so I don't know which is better. There are a few websites that do the same thing. The study was conducted on 20 commercial laying hen farms, 10 farms with battery cages and 10 farms with deep litter systems. Datathief is a (free) computer program to do that. Objective of this study was to validate a mainly environment-based method, the animal needs index (ANI), with animal-based methods: behavioural observations and feather condition scores (FCS). The second category records animals’ responses to that particular environment and management more directly. The first category describes features of the environment and management, which can be considered prerequisites for welfare. It will warn you if too many or too few pixels are detected.Methods available to assess animal welfare at farm level are based on a range of welfare parameters, which can be divided into two categories, environment-based and animal-based parameters. This function will then return the x and y coordinates of each data point. Then one pixel for each data point you wish to extract (default color: pure green). Do the same for the y-axis (default color: pure red). To use this tool, first annotate the plot by adding a single pixel at the start and end of the x-axis in a specified color that does not exist anywhere else in the image (default color: pure blue). If you want to extract a lot of data, or extract data from a continuous line, you are better off using the original Java DataThief package, or one of the many online tools that do exactly this. This means, that apart from the excutable called Datathief.jar, one will has to have the Java Virtual Machine. However, it might be annoying for a large amount of data. This makes it more transparent how the data are being read and makes the results more reproducible. Unlike the Java DataThief package and similar online tools, here the user manually annotates the figure with the data points of their choosing. Inspired by the Java package of the same name. Small utility for retrieving data from figures.
