Effect of synchronizing the rate degradation of protein and organic matter of feed base on corn waste on fermentation characteristic and synthesis protein microbial

Abstract

Synchronization of feed sources of energy and protein can produce a positive influence on microbial protein synthesis, especially in ruminants that are fed low quality feed such as corn waste. Corn waste, including corn straw and corn peri carp are widely used as beef cattle feed. The objective of this research was to determine the effect of synchronizing the rate degradation of protein and energy of feed base on corn waste on rumen fermentation characteristic and synthesis protein microbial on 24 hours in vitro condition. The three synchronization index levels in corn-based feed waste are 0.4 (low); 0.5 (moderate) and 0.6 (high) were used in this study. Characteristics of rumen fermentation observed were pH, individual volatile fatty acids (acetic acid, propionic acid and butyric acid), NH3, C02, CH4, degradation of organic matter, microbial protein production, and efficiency of microbial protein synthesis. Increasing the synchronization index level caused a significant increase (P<0.05) of NH3 (53.60 to 59.07 mg/L) and efficiency of microbial protein synthesis (14.83 to 17.87) , but high synchronization index decrease (P<0.05) the concentration of acetic acid (22.45 mM to 15.95 mM), estimated CO2 (18.69 to 15.50 mol) and CH4 (11.49 to 7.98) in rumen fluid. This result indicated that the improvement of synchronization index can improve the productivity of livestock through increase efficiency of microbial protein synthesis and it reduce global warming.

“…This is presumably because cassava contains easily digestible carbohydrates and the T2 ration also has the lowest crude fiber compared to other treatment rations. According to [9] high digestibility can occur due to rumen microbial growth which is affected by the provision of sufficient rumen degradable protein (RDP) and readily available carbohydrate (RAC). T1 rations numerically had the lowest digestibility compared to other treatment rations, which may be due to their high CF and low CP.…”
