|Title:||Genetic Trends in the Estimated Feed Intake of Angus Cattle||Contributor(s):||Walmsley, Bradley J (author); Henzell, Anthony L (author); Barwick, Stephen (author)||Publication Date:||2017||Open Access:||Yes||Handle Link:||https://hdl.handle.net/1959.11/23432||Open Access Link:||http://agbu.une.edu.au/AAABG%202017/14Walmsley22061.pdf||Abstract:||Genetic trends are presented for the estimated feed intake of young Angus animals at pasture and in the feedlot, and of Angus cows at pasture for a self-replacing, 100d-finished production system. Increases in feed intake over time, both at pasture and in the feedlot, are estimated to have accompanied genetic gains in productivity traits in Angus cattle. The estimated increases are both in feed requirement and residual feed intake, with the latter being smaller in magnitude. The need for industry to record feed intake to facilitate selection for feed efficiency and, in the absence of this, for stocking rate to be managed in commercial herds to offset increases in feed intake, are factors briefly discussed in connection with industry realising benefits from genetic improvement.||Publication Type:||Conference Publication||Conference Name:||22nd Conference of the Association for the Advancement of Animal Breeding and Genetics, Townsville, Australia, 2nd - 5th July, 2017||Conference Details:||22nd Conference of the Association for the Advancement of Animal Breeding and Genetics, Townsville, Australia, 2nd - 5th July, 2017||Source of Publication:||Proceedings of the Twenty-second (22nd) Conference of the Association for the Advancement of Animal Breeding and Genetics, v.22, p. 61-64||Publisher:||AAABG: Association for the Advancement of Animal Breeding and Genetics||Place of Publication:||Fitzroy, Australia||ISSN:||1328-3227||Field of Research (FOR):||070201 Animal Breeding||Socio-Economic Outcome Codes:||830301 Beef Cattle||Peer Reviewed:||Yes||HERDC Category Description:||E1 Refereed Scholarly Conference Publication||Other Links:||http://www.aaabg.org/aaabghome/
