During a four-year period, mature ewes were either shorn in mid-pregnancy or post-partum to study impacts on lamb live weight and survival. Furthermore, placental measurements were collected post-partum from a subset of single-bearing ewes and yearly fleece weights and wool samples were collected from a subset of single- and twin-bearing ewes. Lambs born to ewes shorn in mid-pregnancy were heavier (p&#8201;<&#8201;.05) and displayed greater (p&#8201;<&#8201;.05) survival than those born from post-partum shorn ewes regardless of litter size. Shearing treatment had no effect (p&#8201;>&#8201;.05) on the weight of the placenta, and diameter or the weight of the cotyledons. However, the number of cotyledons was greater (p&#8201;<&#8201;.05) in mid-pregnancy than post-partum shorn ewes. Ewes shorn in mid-pregnancy produced lighter (p&#8201;<&#8201;.05) fleeces with greater (p&#8201;<&#8201;.05) yields. The fleece displayed shorter (p&#8201;<&#8201;.05) staple length, stronger staple strength (p&#8201;<&#8201;.05), and was less (p&#8201;<&#8201;.05) bright with poorer (p&#8201;<&#8201;.05) colour than those shorn in post-partum. © 2017 The Royal Society of New Zealand  aCORDERO  aLANA  aOVEJA  aLAMB BIRTH WEIGHT  aLAMB SURVIVAL  aMID PREGNANCY  aMID-PREGNANCY  aPLACENTA  aWOOL1 aMONTOSSI, F.1 aVIÑOLES, C.1 aKENYON, P.
