The balance of rumen degradable protein and readily available carbohydrate in sheep rations on in vitro fermentability.
Objective: Protein and carbohydrates are substances needed by ruminants, especially sheep. Providing protein and carbohydrates must pay attention to their degradation. In addition, balancing nutrients to meet the nutritional needs of rumen microbes is very important because the unbalanced availability of rumen degradable protein (RDP) and readily available carbohydrate (RAC) at one time can cause suboptimal microbial protein synthesis efficiency.
Materials and methods: Completely randomized design with a nonfactorial pattern of five treatments with three replications. Treatment includes RDP and RAC ratios, namely R1 = 2.30, R2 = 2.00, R3 = 1.70, R4 = 1.50, and R5 = 1.30.
Results: The results showed that the balance of RDP and RAC in sheep ration formulation in vitro had a very significant effect (p < 0.01) on NH3, microbial protein synthesis, total gas, total microbes, and organic matter digestibility (OMD) but had no significant effect (p > 0.05) on rumen pH and dry matter digestibility (DMD).
Conclusion: The optimal balance of RDP and RAC in the formulation of sheep rations in vitro was obtained at a ratio of 2.30 with NH3 (mM) 8.47, rumen pH 5.97, microbial protein synthesis (mg/100 ml) 123, gas (ml/g of material) 145, total microbes (cells/ml) 2.012 × 106, (log CFU cells/ml) 6.3025, DMD 61.0%, and OMD 63.1%.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
