Key Messages: Breeding fr Breech Strike Resistance Wrinkle and Cver relatively quick prgress can be made in breeding terms.. less s fr super fines / fines Reducing dags is mre difficult in high dag cuntry, envirnmental causes f dags swamps genetic prgress Odur and bacteria may be imprtant factrs but will be sme time befre validated and usable by Industry May take sme pressure ff the need fr lw dag, lw urine stain and lw wrinkle?
Key Messages: Breeding fr Breech Strike Resistance Need t find & use high fleece weight, lw dag & lw wrinkle sheep Mre difficult in superfine and fine wl merins; less variatin Breeding Values can assist rate f gain especially when there are a) large numbers f traits t select fr b) reasnable number f traits negatively crrelated Fleece Weight and Micrn Fleece Weight and Wrinkle Fat and Prductivity (Fleece Weight and Reprductin) Wrm Egg Cunt and Dags It takes fcus, grup f fellw breeders n same path and time. t breed curve benders
Key Messages: Breeding fr Breech Strike Resistance Ram Breeding Industry is nw creating new lines f lw wrinkle, lw cver, lw wec, lw dag rams with high relatively fleece weight. Search criteria; Sire, <-0.3 Wrinkle, <-0.3 Cver<-0.1 Dag, Fat>0, Muscle>0, WEC <30, MP+ Order

Key Messages: Sheep Management Imprved pastures and high stcking rates have increased risk f breech strike ver last 50 years Tail dcking methds similar fr strike risk and welfare Castratin methds similar fr strike risk and welfare Dicyclanil and Cyrmazine prvide gd prtectin fr label perids listed n prduct labels Use existing chemicals wisely t delay nset f resistance
Key Messages: Sheep Management Harder t get new chemicals registered, csts much higher Wrms and flies Imprving ur understanding hw current chemicals wrk at DNA level. Targeting genes specific t parasite gd way frward. DNA f pest, hst, bacteria and their interactin with Envirnment prviding new leads
Key Messages: Grwer case studies unmulesed sheep Plan, plan, plan, dn t just stp mulesing need t rebalance basket f all ther cntrl prcedures Wrk in with ther like minded breeders Need clear fcus n a balanced prfitable merin and hw t achieve it; set breeding targets Need t manage bth upsides and dwnsides f intrducing genetics MUST practively market sheep and wl Whle business needs t be n bard
