... The different survival rate of progeny from the two sire lines of Duroc and Pietrain showed that breeds might be different and that choice of breed can be a useful tool to increase animal welfare. Since the breeds were obtained from different breeding programs, it furthermore demonstrates that breeding can be a useful tool to increase animal welfare ( Kanis et al., 2004). ...
... Therefore, pigs must maintain a constant internal body temperature, produce heat, and the remaining excess heat must be released into the environment. This process of generating and dissipating heat is called thermoregulation (Kanis et al 2004). Nienaber and Brown Brandl (2009) noted that indoor climate control in animal housing will not always be within the pig's thermal comfort zone. ...
... The ability of a sow to produce and rear a high number of viable piglets that meet weight targets for a desired age at slaughter is the ultimate goal in pig production. Irrespective of the target slaughter weight, which differs across countries and production systems, both management and breeding programs have to be tailored and continuously optimized to achieve this goal [3,4]. Reproductive traits have been genetically improved over recent decades [5][6][7]. ...
