Using Australian Sheep Breeding Values to increase lean meat yield percentage

This study describes the impact of Australian Sheep Breeding Values (ASBV) for post-weaning weight (PWWT), C-site fatness (PFAT) and eye muscle depth (PEMD) on lamb carcasses within the Australian Sheep Industry CRC Information Nucleus Flock. These results are taken from the 2007 drop progeny, consisting of ~2000 lambs slaughtered at a target weight of 21.5 kg. These lambs were the progeny of sires selected to ensure genetic diversity across various production traits. As expected, the PWWT ASBV increased weight at slaughter, and hot standard carcass weight. Dressing percentage was markedly improved by increasing PEMD ASBV, thus prime lamb producers will be maintaining an animal of similar weight on farm, but delivering a markedly larger carcass at slaughter. Lean meat yield % (LMY%) was highest in the progeny of sires with low PFAT ASBV, which decreased whole carcass fatness and increased muscularity. PWWT ASBV affected carcass composition but had little impact on LMY%, as the decreased fatness was largely offset by increased bone, with relatively little change in muscle content. Lastly, PEMD ASBV had little impact on whole carcass LMY%, but did appear to cause some level of muscle redistribution to the higher value loin cuts, in turn increasing the value of the carcass lean

Revisiting repatriation concerns: organizational support versus career and contextual influences

This paper reviews and integrates two perspectives on repatriate retention: a traditional one, which suggests that the main determinant of repatriate retention is the availability of repatriation support programs; and an emerging one, which focuses on individual career activism in a changing employment context. Results of a study of 133 expatriates from 14 MNCs indicate that both views contribute to our understanding of repatriate retention. Building on the results of our study, we put forward a framework to guide future research. Journal of International Business Studies (2007) 38, 404–429. doi:10.1057/palgrave.jibs.8400273
