Abstract

Managing the variability in pasture quality and quantity is a challenge for beef producers supplying to certified grass-fed beef programs. In southern Australia, the quality during the summer-autumn period is often below the maintenance requirements for livestock. Traditionally, many producers supplement livestock with grains or a grain-based pellet to enhance energy and protein supplies for ruminants grazing on low quality pastures (Lee et al. 1985; Leng 1990). Canola meal (CM) is one protein supplement that has become more available, cost competitive and is an approved Pasture fed Cattle Assurance System (PCAS) supplement (PCAS 2016). Feeding standard guidelines have indicated the rate of supplementing CM can vary from 0.3 to 3 kg DM/d (Blackwood and Clayton 2007; Mailer 2004) for growing cattle. Therefore, the objective of this experiment is to determine the optimum inclusion rates for supplementing canola meal to weaner calves when offered low quality roughages.

OtherIt is with enormous pleasure that we invite you to Perth, Western Australia for the 33rd conference of the Australian Association of Animal Sciences (formerly Australian Society of Animal Production), which will be held at the Esplanade Hotel in the beautiful city of Fremantle, 1st – 4th February, 2021.
For the last 60+ years this conference has brought together animal production scientists, consultants, extension specialists, producers and students to share information – from blue sky research to practical outcomes. The cross-species forum has allowed researchers to glean knowledge and ideas from outside of their areas of reference and provided an opportunity to communicate with a broad range of animal production specialists.
