“…If CO 2 levels varied by 20% or ammonia differed by 5 ppm between rooms, ventilation was increased or decreased accordingly in each room independently to match air quality and temperature across all rooms ( Beaulac and Schwean-Lardner, 2018 ; Beaulac et al., 2019 ). The ammonia and CO 2 results from this study were previously reported ( Jhetam et al., 2022 ). Room temperatures and RH were monitored hourly using iButton Hygrochron temperature and humidity data loggers (Maxim Integrated; San Jose, CA).…”

“…The protocol was approved by the University of Saskatchewan's Animal Care Committee (AUP 19940248). The primary objective of this manuscript focused on the effects of SD on turkey hen behavior, health, and welfare, however, the data regarding the effects of SD on turkey hen performance and environmental conditions have also been reported ( Jhetam et al., 2022 ). A summary of basic performance data is provided in Table 1 for reference.…”

“…Feeder and drinker space were equalized on a per bird basis for each SD treatment (35 birds/feeder; 30 birds/nipple), thereby eliminating impacts of variable feeder and drinker space. Birds were fed a commercial 5-phase diet in specific quantities per bird ( Jhetam et al., 2022 ) and supplemental feeders and drinkers were provided throughout the first 10 d. Diet changes were made when the ration was finished, and feed amounts were adjusted for mortality.…”

“…This study was part of a larger study that included evaluating the effects of SD on turkey hen performance ( Jhetam et al., 2022 ) in addition to health and welfare parameters. Jhetam et al. (2022) observed a linear decrease in BW at 11 wk with increasing SD (30–60 kg/m 2 ) and there was a trend observed for overall BW gain (0–11 wk) to decrease with increasing SD.…”

For the welfare assessment on commercial broiler and turkey farms, not only the recording of animal-based indicators but also the evaluation of the resulting prevalence or rate is essential. Two evaluation methods were compared using data on welfare indicators collected over 1 year from 11 broiler and 11 turkey farms in Germany: the application of normative values from an evaluation framework and the calculation of a benchmark. The evaluation framework had recently been developed in a participatory process that provided an evaluation with target and alarm values. The target range was predominantly based on ethical considerations, while the alarm range was aligned with the current status quo from farm investigations. The 25th percentile and the 75th percentile of the benchmarking were similarly classified as target and alarm. When applying the evaluation framework across all indicators and flocks, 30.6% of broiler flocks were in the target range, while 41.4% were in the alarm range, mostly for indicators such as footpad dermatitis, weight uniformity, and mortality. For turkeys at week 5 or at the end of the fattening period, 51.6% and 32.9%, respectively, were in the target range and 12.3% and 14.4% were in the alarm range. Most alarm classifications were related to footpad dermatitis, low-weight uniformity, plumage damage, and skin injuries. The application of normative values led to a significantly worse average welfare rank over all indicators and flocks for broilers compared to the benchmark, while no difference was observed for turkeys. The farm selection process may have favored turkey farms with better management practices, resulting in a more rigorous benchmark than in broilers. In addition, the farm data used to set the normative values had indicated a poorer status quo in turkeys for certain indicators, resulting in less stringent limits for the alarm range. This highlights the challenges associated with both evaluation methods: normative values are affected by the process and criteria used to set them, while benchmarks are affected by the reference population, which calls for large databases with regular updates. Also, for normative values, developments in the sector and the latest scientific evidence should be used for recurrent validation.
