- Abstract
A total of ten agricultural by-products commonly used in cattle rations in the central and southern regions of Peninsular Malaysia were evaluated. They included broken rice (BR), rice bran (RB), wheat bran (WB), copra cake (CC), malt barley (MB), wet brewers grain (WBG), tofu by product (TBP), soy sauce by product (SSBP), sago pith (SP) and palm kernel expeller (PKE). All samples were subjected to chemical analyses followed by in sacco digestibility study using 3 adult male fistulated Brahman crossed bulls. SSBP and WBG had highest CP content of 24.62% and 24.25%, respectively. SSBP also had the highest metabolised energy (p<0.05) of 17.49 MJ/kg and also the highest sodium content of 3.26%. WP and RB had significantly higher degradation (P<0.05) than other samples at 51.02% and 47.85%, respectively, after 12 h in sacco fermentation. At 24 h in sacco fermentation, WP had significantly the highest (P<0.05) degradability at 62.53% followed by RB (58.43%), MB (54.72%), and BR (53.37%). At 48 h, BR had the highest degradation (P<0.05) of 73.39% compared to all other samples. It was concluded that different protein and energy sources vary in degradability. A proper combination of these feed sources to meet the ruminant nutrient requirements would increase feeding value of the feed formulation.
