Utilization of Ruminal Epithelial Cells by Ruminococcus albus, with or without Rumen Protozoa, and Its Effect
Effects of supplementation with ruminal epithelial cells on fiber-degrading activity and cell growth of Ruminococcus albus (R. albus, strain 7) was tested using a basal substrate of rice straw and formulated concentrate. Cultures of R. albus alone and R. albus with rumen protozoa were grown at 39C for 48 h with an 8.4% crude protein (CP) substrate, 33% of the CP supplemented with either rumina...
متن کاملEffect of acid and alkali treatment of soybean meal on nitrogen utilization by ruminants.
Soybean meal (SBM) was treated with acid or alkali to determine effects on N solubility, in vitro NH3-N accumulation, in situ N degradability, and N digestion and retention in growing lambs. The following SBM treatments resulted in decreased (P less than .05) N solubility and in vitro NH3-N accumulation compared with control SBM: spraying with 2.5 or 5% acetic or propionic acid, soaking in .5 N...

متن کاملEffect of protozoa on rumen protein degradation in sheep.
We have studied the contribution of ciliate protozoa to the degradation of dietary protein, utilizing 5 defaunated and 6 faunated sheep. Rumen samples from these animals were used as inocular for in vitro determination of the degradability of different protein sources: lupine grain, peanut and soybean cake, and fish meal. We also applied the in sacco method to measure the digestibility of soybe...
