In developing south-east Asia countries, mid-quality broiler chicken breeds, such as: New Lohmann, were normally harvested at body weight 1.5-2.0 kgs in 5-6 weeks. In European countries and the United States, hyline broiler chickens breeds, such as: Ross 308, Ross 708, or Cobb 500, can be harvested at weight 4.2 - 5.0 kgs in 9 weeks (Aviagen, 2007 Aviagen, 2014 Cobb-Vantress, 2015). Broiler chickens nowadays have very low feed conversion rate, high growth rate, and less costly nutrition. The fast growth of this meat-type chickens is supported by superior quality feed stuffs which contain high quality nutrients and energy that provided in proper amount. In recent era, protein and amino acids which required were supplied by conventional protein source feed stuffs, such as: soybean meal (SBM). As a by-product in soybean oil industry. SBM contains not only high level of crude protein and digestible amino acids, but also is a good energy source for broiler chickens (Meng and Slominski, 2005). However, price of this commercial imported soybean meal becomes higher when the monetary crises is happened or when the national supply is low. Alternative locally available low-priced feed stuffs should be explored to change over the position of conventional high-priced poultry feedstuffs. One of the alternatives that might be investigated is soy-milk waste (SMW). SMW has also been shown as useful candidate as this by-product in soy-milk industry might contains high quality of nutrients (O'toole, 1999), which in turn should be beneficial in improving quality of meat yield. Aimon and Satrianto (2014) predicted a high trend in SMW availability in the next couple of years due to the increase of soybean consumption and import. A study must be done to explore the benefits of soybean meal dietary substitution with soy-milk waste using growth performance, protien-energy efficiency, and meat quality
