Effect of sustained exposure to elevated ambient temperature during pregnancy on lamb and placental weight around birth. Weighted means for lamb weights and placenta weights at term were calculated from studies in which hyperthermic conditions were induced using approximate circadian rhythms, and measures were taken from either new born lambs, or fetuses within 15 d of predicted full term. Lamb birth weight data were derived from the following 15 papers: [20, 26, 126,127,128,129,130,131,132,133,134,135,136]. Placental weight data were derived from the following 5 papers: [126, 130,131,132, 135]
