IntroductionFeed is the most significant cost in livestock production, representing as much as 60–70% of production outlays (Strauchand Stockton, 2013). In most developing countries, there are problems with the quality and quantity of feed and foragedue to natural calamities, poor soil fertility and lack of natural grasslands, with subsequent effects on ruminant production(Devendra and Leng, 2011). Many hill farmers in South-east Asia do not have enough flat land to produce their own grass,silage or hay and therefore must use imported supplements, which are expensive. Due to successful technology transfer,the livestock sector in Malaysia has grown over the years, especially the poultry and pig sectors (Hassan and Azmie, 2012).However, the ruminant sector continues to lag behind, and it remains underdeveloped, despite considerable scope forexpansion (Abdullah et al., 2012). More research is needed, stating changing the type of feed could potentially offer majorbenefits due to the significant role that feed plays in current production costs.
