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...

An investigation has been made to study the morphology of rumen ciliate protozoa from the subfamily Diplodiniinae. A total 814 rumen fluid samples of adult Indian cattle Bos indicus were collected. The present paper deals with the occurrence of Enoploplastron triloricatum. The body dimensions and variations of characters recorded from the specimen taken at random (n=50) from different slides an...

the effect of three levels of eucalyptus leaf (0, 28.65 or 57.37mg/200mg substrate), which were either oven, freeze or air dried on in vitro ruminal fermentation characteristics was assessed. the studied parameters were in vitro gas production (ivgp), methane production, ammonia (nh3-n) concentration, in vitro organic matter degradability, partitioning factor (pf) (ratio of substrate truly degr...

in this trial, the effect of different levels of echum amoneum (ea) (0.3, 30, 300 or 3000 µl) on in vitro ruminal fermentation characteristics and methane production was assessed. the parameters studied were in vitro gas production (ivgp), methane production, ammonia (nh3-n) concentration, in vitro organic matter degradability (ivomde), partitioning factor (pf) (the ratio of substrate truly deg...

This study examined the reticulo-rumen characteristics of the microbial community and its fermentative characteristics in milk-fed, at weaning and finished lambs in a conventional fattening system. Five lambs were assigned to each of three groups: milk-fed lambs slaughtered at 30 days (T30), weaned lambs slaughtered at 45 days (T45) and 'finished lambs' slaughtered at 90 days (T90). At slaughte...

in this expriment, the effect of different levels of ziziphus zizyphus(zz) (0, 30 or 60 mg) on fermentation parameters, total protozoa population  and three sub family of protozoa  entodiniinae, ophryscolecinae, diplodiniinae and family of isotrichdaeandmethane gas production was assessed using in vitro method and a completely randomized design. the rate of gas production for the insoluble frac...

the effect of three levels (0, 28.65, 57.31mg /200mg substrate) of golpar (heracleum persicum: hp) on in vitro rumen ecosystem and on methane production was assessed. gas production (gp) was recorded from 1 to 54h past of incubation. the parameters studied were in vitro gas production (ivgp), methane production, ammonia-n concentration (nh3-n), in vitro organic matter degradability (ivomde), pa...
