A postgastric, fermentative breakdown of structural plant tissue was demonstrated for green turtles. About 90% cellulose was hydrolyzed. Bacterial and protozoan numbers compared with those of the rumen.

I . A technique for the separation and colorimetric estimation of z,4-diaminopimelic acid (DAP) using automated ion-exchange chromatography coupled with an acid ninhydrin detection system is described. 2. Only traces of DAP were found in rumen protozoa and no DAP was detected in rumen fluid prepared by ultracentrifugation or dialysis. 3. The concentration of DAP in rumen bacteria from sheep on ...

Five total mixed rations prepared from finger millet (Eleusine Coracana) straw as a roughage (48%) and mixed concentrate (52%), supplemented with a 1% isoacid mixture (i-C4, i-C5, C5 and phenylacetic acid in equal proportions) or oil (groundnut oil, 5% more than the control) or urea (5% more nitrogen than the control), and protein (groundnut cake, 5% more nitrogen than the control) were given i...

Therapeutic efficacy of certain poly herbal formulations and probiotics along with heterologous cud transplantation was evaluated in simple indigestion in buffaloes. A total of 18 buffaloes suffering from simple indigestion were treated with Suruchi bolus (10 g twice daily) or Gastricare powder (15g twice daily) or Yeasacc bolus with heterologous cud from healthy sheep. Clinical examination and...

Whether live bacteria are required to culture the rumen protozoa Entodinium exiguum and E. caudatum in vitro was studied. Treatments were protozoa plus antibiotics (PA), PA plus autoclaved bacteria (PAB) or protozoa plus live bacteria (PLB). Generation times at 24 h were 22.8 and 31.0 h for E. exiguum and E. caudatum. Protozoal concentrations were unaffected by the absence of bacteria up to 48 ...

Six sheep fitted with ruminal fistulas were used in a repeated measurement design with two 24-d periods to investigate the effect of adding a specific mixture of essential oils (MEO) at 0 (control), 0.8 and 1.6 ml/d on apparent nutrient digestibility, rumen fermentation characteristics, rumen microbial population and blood chemical metabolites. Animals were fed with a 50:50 alfalfa hay: concent...
