Bacterial protein degradation by different rumen protozoal groups.
Bacterial predation by protozoa has the most deleterious effect on the efficiency of N use within the rumen, but differences in activity among protozoal groups are not completely understood. Two in vitro experiments were conducted to identify the protozoal groups more closely related with rumen N metabolism. Rumen protozoa were harvested from cattle and 7 protozoal fractions were generated imme...

متن کاملReponses of sheep to a vaccination of entodinial or mixed rumen protozoal antigens to reduce rumen protozoal numbers.
Two rumen protozoa vaccine formulations containing either whole fixed Entodinium or mixed rumen protozoa cells were tested on Merino sheep with the aim of decreasing the number and/or activity of protozoa in the rumen. Negative control (no antigen) and positive control (Tetrahymena corlissi antigens) treatments were also included in the experiment. Blood and saliva were sampled to measure the s...
متن کاملRumen ciliate protozoal fauna of reindeer in Inner Mongolia, China.
Rumen ciliate species and composition were surveyed on the reindeer kept in Inner Mongolia, China. As a result of survey, all the reindeer had the same 18 species of 8 genera of the ciliates in their rumen. Appearance of Entodinium parvum is the first record in this host species. Of the species detected, 15 species including Entodinium anteronucleatum, E. bicornutum, Enoploplastron confluens an...
متن کاملRelation of rumen ATP concentration to bacterial and protozoal numbers.
Cultures of Streptococcus bovis and mixed populations of rumen bacteria were used to investigate the concentration of ATP and rumen bacterial numbers at various stages of growth. ATP, extracted with Tris buffer, was analyzed using the firefly luciferin-luciferase bioluminescent reaction. ATP concentrations of S. bovis and mixed cultures of rumen bacteria significantly correlated with live cell ...
