Title: | Estimates of Genetic Parameters for Seasonal Weight Changes of Beef Cows | Contributor(s): | Meyer, Karin (author); Colditz, Ian (author) | Publication Date: | 2015 | Open Access: | Yes | Handle Link: | https://hdl.handle.net/1959.11/19021 | Open Access Link: | http://www.aaabg.org/aaabghome/AAABG21papers/Meyer21193.pdf | Abstract: | Genetic parameters were estimated for seasonal body weight changes of cows and weaning weight of their calves in two beef herds run at pasture in a Mediterranean climate. Heritability estimates for weight changes were low. Cows predisposed to lose more weight were also likely to gain more weight, and larger cows had greater genetic potential for weight changes. Low to moderate genetic and permanent environmental correlations indicated that cows with greater seasonal weight changes weaned heavier calves, due in part to the genetic association between weaning weight and cows' mature body weight. Results indicate that in this environment, scope to select for heavy weaning weight without penalty to cow body weight during periods of seasonal feed scarcity is limited. | Publication Type: | Conference Publication | Conference Details: | AAABG 2015: 21st Conference of the Association for the Advancement of Animal Breeding and Genetics, Lorne, Australia, 28th - 30th September, 2015 | Source of Publication: | Proceedings of the Association for the Advancement of Animal Breeding and Genetics, v.21, p. 193-196 | Publisher: | Association for the Advancement of Animal Breeding and Genetics (AAABG) | Place of Publication: | Armidale, Australia | ISSN: | 1328-3227 | Fields of Research (FoR) 2008: | 070201 Animal Breeding | Fields of Research (FoR) 2020: | 300305 Animal reproduction and breeding | Socio-Economic Objective (SEO) 2008: | 830301 Beef Cattle | Socio-Economic Objective (SEO) 2020: | 100401 Beef cattle | Peer Reviewed: | Yes | HERDC Category Description: | E1 Refereed Scholarly Conference Publication | Publisher/associated links: | http://www.aaabg.org/aaabghome/proceedings21.php |
