Seasonal variation in pig production has been implicated in variation in productive and reproductive performance through direct and indirect effects of temperature on physiological responses, including intestinal integrity, endocrine signaling, adipose mobilization, and insulin regulation. Heat stress in pig production results in industry losses resulting from slower growth rates, inconsistent mar...

Wendy Rauw, due to the nature of the research, involving the thermal environment and production phases, was unable to identify how the authors considered in the analysis the variation in the initial weight of the animals, between the values of 30.60 kg to 40.40 kg. the animals' initial weight as a covariate, is that a possibility or not?
