Temperature is an important factor in embryonic development because temperature plays a role in determining the overall development of the embryo. The effect of high temperature on the embryo will cause the embryo to make a defense by diverting some of its energy to form thermal homeostasis, which is a physiological response. The purpose of this study was to analyze heat stress on embryonic development. This study used a systematic literature review (SLR) following PRISMA guidelines and gathered the sample of papers through the PubMed databases using keywords categorized as heat, stress, and embryo. There were 31 papers used as samples. The result showed that hyperthermia in chickens caused an increase in heart rate per minute as a result of temperature pressure. It affects the hatching percentage, hatching time, weight, and mortality rate in chicken embryos. In summary, heat stress has an impact on embryonic development heat stress gives an impact on the development of embryos.
