Abstract:
The present study was conducted in an Assaf flock in which the FecB (Booroola) mutation was segregated to determine whether the FecB mutation affects birthweight and the pre- and post-weaning growth rate of ewe lambs, as well as the mature bodyweight of ewes. Significant differences (P = 0.01) in birthweight (mean ± s.e.m.) were found between BB ewe lambs (4.03 ± 0.08 kg) and B+ and ++ ewe lambs (4.16 ± 0.04 and 4.32 ± 0.07 kg, respectively), which themselves did not differ significantly (P > 0.05). An FecB-associated maternal effect on the birthweight of ewe lambs was also detected, with the birthweight of lambs born to BB mothers (3.93 ± 0.08 kg) being significantly (P < 0.0001) different from the birthweight of lambs born to B+ and ++ mothers (4.26 ± 0.04 and 4.33 ± 0.07 kg, respectively), which did not differ significantly. The genotypes of the lambs did not affect their preweaning growth rate. However, the post-weaning growth rate of ewe BB lambs (274 ± 5 g day-1) was significantly (P = 0.05) different from the similar (P > 0.05) post-weaning growth rates of B+ and ++ lambs (284 ± 3 and 290 ± 4 g day-1, respectively). The genotype at the FecB locus also affected the mature bodyweight of ewes, with that of BB ewes (67.3 ± 1.4 kg) being significantly (P < 0.001) different from the similar mature bodyweight of B+ and ++ ewes (70.8 ± 1.1 and 70.1 ± 1.7 kg, respectively). © CSIRO 2006.
