“…After that there was a gradual decrease in daily urinary N excretion until inoculation (on 34 day) and gradually increased up to the 3 to 6 days reaching almost constant level at the end of the digestion trial. Results in the present study are in agreement with that of Matsumoto et al (1991), and are opposite with that of Fujihara et al (2002) using goats. Therefore from the above evidence, there is no relationship between protozoa population in the rumen and urinary N excretion when there is a lapse in time after inoculation.…”

“…This clearly indicates that the amount of nucleic acid metabolized to be higher in defaunated than in faunated lambs. In our previous experiment using goats, contrarily, there was no clear difference in defaunated and faunated periods (Fujihara et al, 2002). Figure 3 shows the daily changes in plasma allantoin levels with time after inoculation, and there were no clear trend as same as the result of our previous experiment, in which there were also no increases or decreases in plasma allantoin level …”

Thirty six zebu steers (35 Gobra and 1 Maure), 2.5 years-old on average, were equally alloted in 3 groups fed different crop by-product based diets. For diets 1 and 2, molassed rice straw and molassed millet straw were offered ad libitum as a basal diet while the other ingredients were mixed and given (2.5 kg/animal/d) as supplement 1 and 2, respectively. In diet 3, all ingredients were mixed and given as a compound feed. The energy content was higher in diet 3 (0.83 FU/kg DM) than in diet 1 and 2 which were isoenergetic, 0.65 and 0.63 FU/kg DM, respectively. Animals were group-fed twice daily (at 08.00 and 16.00 h) during 3.5 months. Diets offered and refusals were daily measured. Cattle were monthly weighed, their body condition was scored using 2 scales of 6 (BCS 0-5 ) and 9 (BCS 1-9 ) points, and body lipids and energy were estimated. The level of intake of steers was 101, 94.3, and 148.3 g DM/d/BW 0.75 for the 1 rst , 2 nd and 3 rd groups, respectively. Groups 1 and 2 had average daily gain similar (ADG) (446.7 and 425.5 g BW/animal, respectively) and gain in BCS 0-5 (+0.8 points) and in BCS 1-9 (+1.9 points). A spectacular development of the hump was observed in cattle of the 3 rd group which was submitted to the richest diet. They also gained more (P<0.01) weight (AOG : 1012 g BW/animal), BCS 0-5 (+1.9 points) and BCS 1-9 (+3.5 points) than did the others groups. Increased rate of BW gain resulted in an acceleration of body lipids deposits (22.8 kg in the 3 rd group vs 11.5 kg in the 1 rst and 11.6 kg in the 2 nd group) and in gain in body net energy (936.6 MJ in the 3 rd group vs 473.9 MJ in the 1 rst and 490.3 MJ in the 2 nd groups). Each kg of gain in BW contains on average 264.7 g of lipids and 11.4 MJ of net energy.

“…Sixteen Black Belly rams (average live weight: 43.7 6 5.5 kg, 2-year old) fitted with ruminal and duodenum cannulas were used in this trial. Eight rams were defaunated using a milk diet derived from the method Fujihara et al (2003). During the defaunation process, the diet was gradually changed from a fresh immature grass to a milk powder diet over 10 days.…”

The effects of defaunation on growth and digestion were measured in sheep fed fresh Digitaria decumbens grass cut at four stages of regrowth 14, 28, 42, and 56 days, and with different protein to energy (P/E) ratios. Two completely randomized designs trials (growth and digestion) were conducted using faunated animals, defaunated rams and protozoa free lambs. The digestion trial: eight faunated and eight defaunated rams fitted with ruminal and duodenal cannulas were fed 4 diets (diets D1 to D4) to measure digestion parameters. The dietary P/E ratios were 120 (D1), 130 (D2), 130 (D3), and 140 (D4) g PDIN/UFL (Protein Digested in the small Intestine supplied by microbial protein from rumen-degraded protein/Feed Unit for Lactation) and the grass stages of regrowth were 56, 42, 28, and 14 days, respectively. Increasing the dietary P/E ratios increased dry matter intake (DMI) and the total tract digestibility of organic matter (OM), NDF and CP. Defaunation decreased DMI, except for rams fed D4 diet. Defaunation also decreased total tract digestibility of OM except for rams fed D1 diet and that of NDF except for rams fed D1 and D4 diets. Increasing the dietary P/E ratios also increased nitrogen intake and ammonia (NH 3 ) concentration in the rumen, whereas defaunation decreased them. The dietary P/E ratio increased non-NH 3 nitrogen and microbial nitrogen duodenal flows and microbial efficiency. Defaunation did not affect duodenal flows of neither non-NH 3 nitrogen and microbial nitrogen or microbial efficiency. The growth trial: 20 faunated and 20 protozoa free lambs were fed four diets (diets D5 to D8) to measure their average daily gain (ADG). The dietary P/E ratios were 60 (D5), 70 (D6), 80 (D7) and 100 (D8) g PDIN/UFL and the stages of regrowth were 56, 42, 28, and 14 days, respectively. DMI of lambs increased with P/E ratio. Protozoa free lambs had greater DMI than faunated ones when fed D7 diet (80.8 v. 74.9 g/kg LW 0.75 , respectively). The ADG of the lambs increased with P/E ratio. Fed on the same D5 diet, protozoa free lambs had greater ADG than faunated lambs (29.8 v. 11.6 g/day, respectively). In conclusion, animal response to defaunation was modulated by the P/E ratio of the D. decumbens grass diets. Defaunation increased ADG of lambs fed forage with the lowest P/E ratio, while digestion and nitrogen duodenal flows of rams fed the lowest P/E ratio were not affected.
