|Title:||Benefits of MOET and JIVET in Optimised Sheep Breeding Programs||Contributor(s):||Granleese, Tom (author); Clark, Sam A (author) ; Van Der Werf, Julius H (author)||Publication Date:||2013||Handle Link:||https://hdl.handle.net/1959.11/14476||Abstract:||The additional genetic gain from implementing multiple ovulation and embryo transfer (MOET) and juvenile in vitro embryo production and embryo transfer (JIVET) additional to using artificial insemination (AI) and natural mating (N) in sheep breeding programs was assessed. This study was a stochastic simulation and selection based on optimum contributions for varying levels of inbreeding restriction. The genetic gain achieved after 20 years for an AI/N program was 4.89 and 5.16 units of genetic SD (h²=0.3) when inbreeding was restricted to 1% and 2% per generation, respectively. The additional gain from MOET was 23% and 28% and the additional gain from the addition of JIVET to MOET and AI/N increased genetic gain 60% and 56% for these two levels of inbreeding when compared to AI/N. With the addition of each technology, generation interval decreased, as did the number of breeding ewes.||Publication Type:||Conference Publication||Conference Name:||20th Conference of the Association for the Advancement of Animal Breeding and Genetics: Translating Science into Action, Napier, New Zealand, 20th - 23rd October, 2013||Conference Details:||20th Conference of the Association for the Advancement of Animal Breeding and Genetics: Translating Science into Action, Napier, New Zealand, 20th - 23rd October, 2013||Source of Publication:||Proceedings of the Twentieth Conference of the Association for the Advancement of Animal Breeding and Genetics, p. 94-97||Publisher:||AAABG: Association for the Advancement of Animal Breeding and Genetics||Place of Publication:||Palmerston North, New Zealand||Field of Research (FOR):||060412 Quantitative Genetics (incl Disease and Trait Mapping Genetics)||Socio-Economic Outcome Codes:||830311 Sheep - Wool||Peer Reviewed:||Yes||HERDC Category Description:||E1 Refereed Scholarly Conference Publication||Other Links:||http://www.aaabg.org/aaabghome/proceedings20.php||Series Name:||Proceedings of the AAABG ...
