Food produced via fermentation with mesophilic bacteria has been used to confer health benefits. In contrast, mammalian physiological responses to the intake of thermophile-fermented products have not been thoroughly investigated. We examined the effects of administering a compost extract consisting of fermented marine animals with thermophiles, including Bacillaceae, to pregnant sows and piglets. Retrospective studies were performed on two different swine farms (n=330–1050 sows). The rate of stillbirth was markedly lower in all parities of the compost extract-fed group compared to those of the control group (p≦0.001). Additionally, the birth to weaning period of newborns was significantly shorter (p<0.0001), while the ratio of weanlings per liveborn piglets was increased by more than 6.5% in the compost extract-fed group. Thus thermophiles and their products in the compost extract might promote growth and reduce stillbirths of piglets during the birth to weaning period.
