Experiments were carried out in vivo to investigate the pathways of ammonia incorporation into rumen bacteria, bacterial fractions and free amino acids within the bacteria. Steers were alternately given two isoenergetic, isonitrogenous diets containing the nitrogen mainly as either urea or decorticated groundnut meal (DCGM). At the end of each period on a given diet, a solution of 15NH4Cl was i...

This study was conducted to investigate effects of disodium fumarate (DF) on fermentation characteristics and microbial populations in the rumen of Hu sheep fed on high-forage diets. Two complementary feeding trials were conducted. In Trial 1, six Hu sheep fitted with ruminal cannulae were randomly allocated to a 2 × 2 cross-over design involving dietary treatments of either 0 or 20 g DF daily....

the major aim of this study was to compare the morphology and activity of rumen protozoa of khuzestan water buffalo and holstein cow using in vitro digestibility and gas production parameters of steam treated sugarcane pith. rumen fluid obtained from two buffalo and cow steers fed the same diet, 30:70 concentrate: forage. to separate rumen protozoa, antibiotic solution and fungicides were added...

an in vitro experiment was conducted to determine the effect of supplemental non-fiber carbohydrate(nfc) on the disappearance kinetics of cellulose (ce) by mixed ruminal microorganisms. non-supplementedor nfc supplemented cellulose (467 mg nfc/g cellulose as sucrose (cesu) or starch (cest) or a 1:1 mixtureof sucrose + starch (cesust)) were incubated for 24, 48, and 96 h at 39°c. after each incu...

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...

Differences in the nutritive value of four grades of stackburned yenow maize, obtained from a single storage unit in Mozambique, were examined. Samples were analysed for chemical composition, and subjected to the fonowing in vitro assays for estimating digestibility: total dietary fibre and pancreatin for non-ruminants, and gas production using sheep rumen fluid for ruminant livestock. Samples ...
