Effect of Protein Sources on Rumen Microbial Protein Synthesis Using Rumen Simulated Continuous Culture System
A rumen simulated continuous culture (RSCC) system was used to study the influence of supplementation of the three different types of protein sources such as urea, casein and soy protein on rumen microbial synthesis in terms of rumen microbial synchronization. The urea treatment showed the highest pH value. Ammonia nitrogen concentration was rapidly increased after feeding and not significantly...
متن کاملEffect of Phosphorus Supplementation to Ammoniated Rice Straw on Rumen Fermentability, Microbial Protein Synthesis and in vitro Nutrient Degradability
The effect of phosphorus supplementation to ammoniated rice straw was studied. The in vitro experiment was carried out following the first stage of Tilley and Terry method. The treatments consisting of four diets were A= 50% ammoniated rice straw + 50% concentrate (control), B= A + 0.2% phosphorus (P) supplement, C= A + 0.4% phosphorus (P) supplement, and D= A + 0.6% phosphorus (P) supplement o...
متن کاملNutritional interdependence among rumen bacteria during cellulose digestion in vitro.
A study has been made of the promoting effect of starch on cellulose digestion by mixed rumen bacteria in a cellulose-urea medium. Starch supplementation of the medium promoted the growth of bacteria that required neither amino acids (AA) nor branched-chain fatty acids (BrFA). The growth of these bacteria was followed by the growth of AA-dependent bacteria, AA- or BrFA-dependent bacteria, BrFA-...
متن کاملEFFECT OF VARIOUS NON PROTEIN NITROGEN SOURCES ON IN VITRO DRY MATTER DIGESTIBILITY, AMMONIA PRODUCTION, MICROBIAL GROWTH AND pH CHANGES BY RUMEN BACTERIA
Four slow releasing non-protein nitrogen (NPN) sources viz. urea-straw (US), urea-starch (UST), biuret-straw (BS) and biuret-starch (BST) were compared with cotton seed meal (CSM) as control nitrogen source. In all experiments, 2% nitrogen level on DM basis in contents of each fermentation flask were maintained through replacing 30, 50 and 70% of CSM by respective NPN source. Four in vitro expe...
متن کاملEffects of Forage Sources on Rumen Fermentation Characteristics, Performance, and Microbial Protein Synthesis in Midlactation Cows
Eight multiparous Holstein cows (632±12 kg BW; 135±16 DIM) were used in a replicated 4×4 Latin square design to evaluate the effects of forage sources on rumen fermentation characteristics, performance, and microbial protein (MCP) synthesis. The forage portion of the diets contained alfalfa hay (AH), oat hay (OH), Leymus chinensis (LC), or rice straw (RS) as the primary source of fiber. Diets w...
