Invited review: Enhancing quality of dairy cattle research through adequate power analysis. By Wang et al., page 8981. Animal research necessitates controlled experiments and statistical hypothesis testing to evaluate treatment effects and answer specific research questions. Given the logistical challenges of sampling entire dairy cow populations, selecting an appropriate group with sufficient sample size is vital for reliable results. Power analysis, which evaluates the probability of detecting true treatment effects, is critical for designing robust experiments.
