“…The fermentation efficiency index (FE, expressed as a %) was calculated according to the equation: FE = (0.622 A + 1.092 P + 1.56 B) 100 / (A + P + 2 B) (Baran and Žitň an 2002) where A, P and B represent the molar proportions (mol%) of acetate, propionate and butate, respectively, in the total SCFA concentration.…”

The aim of the in vitro study was to determine the effect of corn dried distillers grains with solubles (corn DDGS), used as a replacement for the concentrate ingredients of sheep diet, on rumen fermentation. The material for the study was the ruminal fluid of Polish Merino sheep which was incubated during 4-, 8-or 24-hour periods. Five groups of samples were prepared for in vitro fermentation: C -control, incubated with the substrate consisting of the concentrate ingredients; D1, D2 and D3, where DDGS was used as a substrate added in proportions of 10, 20 and 30% of dry matter of the concentrate; and D4, where 100% DDGS was used as a substrate. After fermentation, the gas and short chain fatty acids (SCFAs) analyses were performed using gas chromatography. The ammonia concentration and pH were also determined, and the SCFA utilization index (NGR), the fermentation efficiency (FE) and the index of cell yield of ruminal microorganisms (CY) were calculated. This research showed no effect of DDGS on the methane emission. The positive correlations between the amount of methane and ammonia concentrations in the 8-and 24-hour fermentation periods were found. DDGS addition increased propionate proportion, but decreased production of acetate (p<0.01). Additionally, D1, D2, D3 and D4 substrates lowered isobutyrate (p<0.05) and isovalerate (p<0.01) production. Based on the results obtained, it can be stated that partial substitution of the concentrate ingredients with DDGS did not have deleterious effect on sheep rumen fermentation processes.

“…However, the value for co-supplementation was higher than that for Enz-supplementation by about 1% and higher than that calculated for control by about 2%. Calculation of fermentation efficiency is based on convertion of hexose energy to VFAs energy on the basis of equations worked out by Orskov (1975) and modified by Baran and Zitnan (2002). Metabolism of VFAs is less efficient than metabolism of glucose as more energy is used for formation of one mole of ATP (Livesey and Elia, 1995).…”

With the objective of improving the impact of multi-enzymes feed additives on cecal fermentation pattern and rabbit metabolism, sodium bentonite was co-supplemented with "Kemzyme", a multi-enzyme blend of Kemin Agrifoods Europe. Co-supplementation decreased cecal pH value, increased total VFAs concentration, increased propionate at the expence of acetate and butyrate, increased fermentation efficieny and VFAs utilization. Additionally, co-supplementation increased serum glucose concentration and decreased serum triglycerides and cholesterol concentrations. Cecal ammonia nitrogen and serum urea concentration were also decreased by co-supplementation while no change was recorded in serum total proteins concentration. The study therefore, suggested that, coupling bentonite to multi-enzyme feed additives could improve the impact of such enzymes on cecal fermentation pattern and rabbit metablism.

“…according to the method of Mathew et al (1997). After the results of VFAs molar proportions had been received, the fermentation efficiencies (FE) were calculated on the basis of the equation worked out by Orskov (1975) and modified by Baran & Zitnan (2002): FE = (0.622a + 1.092p + 1.56b) 100/(a + p + 2b)…”

“…In contrast, addition of urea alone exerted a declining effect on fermentation efficiency by modifying cecal VFAs profile in the direction of increased acetate. Calculation of fermentation efficiency is based on convertion of hexose energy to VFAs energy on the basis of equations worked out by Orskov (1975) and modified by Baran & Zitnan (2002).…”

Seventy six New Zealand white rabbits of about 700 ± 80 gm live weight were used to evaluate the influence of diet supplemented with urea-bentonite combination on cecal characteristics, metabolism and rabbit growth performance. The rabbits were assigned into four dietary treatments control, bentonite-supplemented (with 2.5% sodium bentonite), urea-supplemented (with 1% urea) and urea -bentonite co-supplemented (1% urea+ 2.5% sodium bentonite). Co-supplementation decreased cecal pH value and ammonia nitrogen (NH 3 -N) concentration, increased total volatile fatty acids (VFAs) concentration, increased butyrate at the expence of acetate and propionate, increased fermentation efficieny and bacterial mass. Additionally, co-supplementation increased serum total proteins and glucose concentrations while no change was recorded in serum urea and creatinine concentrations. Serum levels of AST were decreased in all experimental groups in comparison with control group whereas, serum levels of ALT were increased only by addition of urea alone. Moreover, urea-bentonite combination achieved an improvement in live weight gain and feed conversion effeciency by about 32% and 33% respectively with reference to control and thus considered cost effective. The study indicates that, a low cost urea-bentonite combination can replace about 50% of protein content of the high cost conventional rabbit feed and additionally improve rabbit growth performance that would be a valuable feeding strategy in developing countries.
