Several systems of models were developed the thermodynamic-like theory of adaptation of ensembles and several families of models of individual adaptation. Historically, the first group of models was based on Selye's concept of adaptation energy and used fitness estimates. Two other groups of models are based on the idea of hidden attractor bifurcation and on the advection-diffusion model for distribution of population in the space of physiological attributes. We explore this world of models and experiments, starting with classic works, with particular attention to the results of the last ten years and open questions.In pregnant sows, heat stress (HS) not only affects sows, but also has long-term effects on offspring growth. However, it is still unclear how HS in pregnant sows influences offspring skeletal muscle development. In this study, 12 sows with similar body conditions were assigned into either a control (CON) or an HS group. The CON sows were housed at 18-22 ℃, and the sows in the HS group were housed at 28-32 ℃ from day 85 to 114 of pregnancy. The results showed that maternal HS decreased the total protein content (P less then 0.05) and prolactin level (P less then 0.05), yet increased the triglyceride content (P less then 0.05) of milk. The piglets of both groups had similar body weight and longissimus dorsi (LD) muscle weight at birth, but body weight (P less then 0.05) and LD weight (P less then 0.05) was significantly lower at weaning age in the HS group. Increased expression of myostatin (MSTN) (P less then 0.05) and its receptor (P less then 0.05) in the LD of HS piglets was observed at weaning. The following decreased in HS piglets expression of serine/threonine-specific protein kinase (P less then 0.05), the mammalian targe
