Mortality data and associated variables
This is an Excel (.xlsx) file derived from an Access database of cumulative mortality data collected in the field from farm records in the UK, Sweden and the Netherlands. Associated data include housing system, flock size and genotype. See Notes sheet for description of abbreviations
Predicted CM for a free range flock reaching 72 weeks at different times of year (modelled from 2,848 flocks, on 1,649 farms, from six studies).

Box plots for mortality in each housing system between 60 and 80 weeks of age using the full data set from 10 studies (3,851 flocks).
<p>Box plots for mortality in each housing system between 60 and 80 weeks of age using the full data set from 10 studies (3,851 flocks).</p
Shows the predicted change in mortality over the lifetime of a flock for each breed (or genotype group) represented in the dataset.
<p>Predictions were generated assuming a date of 1st July 2012 for a free range housing system.</p
Effects of increasing levels of cumulative mortality at 72 weeks on cumulative energy demand (CED) and greenhouse gas emissions (GHGE) for free range egg production.
<p>Levels of up to 30% are modelled. The vertical gridlines show values for the 1st quartile, median, 3rd quartile and upper adjacent value associated with the mean CM of 10%.</p
Effect of skin temperature on threshold.
<p>For lame and non-lame birds, the modelled predictions (+/−95% CI) of the effect on thermal nociceptive threshold of skin temperature (keeping other factors in the model at their reference values).</p
Effects of meloxicam on skin temperature.
<p>Modelled predictions (means ±95% confidence intervals) of skin temperature for lame and non-lame birds administered saline or meloxicam (keeping all other variables in the model at reference values).</p
Key sample characteristics for birds administered butorphanol or saline (n = 76).
1<p>Mean±SD (range).</p>2<p>Value assigned according to a severity scale of 0–4, where 0 =  none, 4 =  severe open ulcers (Welfare Quality, 2009).</p>3<p>In those individuals with an identified pathology the prevalence of each pathological ‘type’ was also calculated. Each type was recorded independently (therefore allowing >100% total).</p
Position of reflective markers for kinematic data collection from a broiler chicken.
