Cím:	Effects of heat stress on the performance of primiparous and multiparous sows and their progeny : a review / Arth David Sol Valmoria Ortega, Csaba Szabó
Dátum:	2022
Megjegyzések:	High ambient temperature (AT) is a burden that can negatively influence the productivity of pigs. Highly prolific sows with high metabolic demands during gestation and lactation are sensitive to hot temperatures. High AT exacerbates their metabolic heat production during these stages of reproduction, and they can suffer heat stress (HS). Considering the possibility of varied responses of sows at different parity to HS, this paper aims to review the effects of gestational HS on the reproductive performance of primiparous and multiparous sows. Concerning the possible difference in their performance, this paper will also look into the production performance of their progeny. Based on the reviewed manuscripts, gestational HS experienced by sows at any time of gestation can negatively affect their reproductive performance. Primiparous and multiparous sows' response to gestational HS differs, with the former having been highly affected by the stressor. Primiparous sows are less capable of thermoregulation upon HS challenge and greatly suffer from its reproductive consequences. The impact of HS was also observed in the production performance of their offspring. The growers and finishers born from primiparous sows had lighter average daily gain and were less efficient in converting feed into body weight gain, respectively, than the offspring of multiparous sows. Nevertheless, offspring from both parities responded with similar carcass quality. Although we reviewed these differences, the lack of research on this topic limits our information on the progeny's production performance differences at the weanling stage. Therefore, further research in this area is needed.
