Growth, mortality and wool cover of F1 lambs.h[electronic resource]  c1997  aAbstract: Sumatra ewes were mated to give Java Fat-tail crossbred (E1), Virgin Island crossbred (H1) and purebred Sumatra (S) lambs, or were inseminated to give Barbados Blackbelly crossbred (B1) lambs. A total of 882 lambs were born to 407 ewes in 568 lambings. Average litter size was 1.55 and lamb mortality to weaning at 3 months was 22.5%. Weights of lambs averaged 1.83 kg at birth and 8.7 kg at weaning. For female lambs only, weights averaged 14.4 kg at 6 months and 17.9 kg at 9 months of age. At weaning the average increases in weight of the crossbreds above S were E1 10–13%, H1 14–15% and B1 32%. At 3 months of age all breed groups had similar wool scores, but in older animals the ranking was B1 (least wool) &lt H1 &lt E1 &lt S (most wool).  aBarbados Blackbelly  aLambs  aVirgin Islands  aCrescimento  aCruzamento  aPerformance  aGrowth  aHair sheep  aJava Fat-tail  aOvino deslanado  aSumatra1 aBRADFORD, G.
