Genetically divergent prime lambs were supplemented with Spirulina and had ad libitum access to Lucerne hay in a nine-week feeding trial. The main objective was to model residual feed intake, liveweight gain, standardised daily feed intake (SDFI), feed conversion ratio and daily feed intake (DFI) and test for sire breed and sex variations. Level of Spirulina supplementation and sex were found to have no independent effects on lamb feed intake (P>0.05). However, DFI and SDFI in Merino sired lambs were lower than in their crossbred counterparts (P<0.023). Merino ewe lambs consumed more Lucerne hay than wethers (P<0.05). These findings could prove useful when balancing feed resources to match Spirulina supplementation levels and lamb breeding management goals.

|Other||The joint US-Canada organizing committee is proud to welcome you to the 10th World Congress on Genetics Applied to Livestock Production (WCGALP) being held from 17 – 22 August 2014 at the Westin Bayshore Conference Center situated on the bay in the gorgeous city of Vancouver, British Columbia, Canada. |
This congress is the premier conference for researchers and professionals involved in genetic improvement of livestock. Delegates from around the world gather every four years to attend the scientific program and network with colleagues. This 10th WGCALP builds from previous successful congresses in Madrid (1974 and 1982), Lincoln (USA, 1986), Edinburgh (UK, 1990), Guelph (Canada, 1994), Armidale (Australia, 1998), Montpellier (France, 2002), Belo Horizonte (Brazil, 2006) and Leipzig (Germany, 2010).
