L'experimentation a dure 42 jours. Tandis qu'un lot temoin (lot 0) ne recut aucune supplementation, les lots 1, 2, 3 recurent respectivement 0,15 %, 0,20 % et 0,25 % de leur ration en jus de rumen lyophilise, tandis que le lot 4 recevait de la virginiamycine a 20 ppm. A la fin de l'experimentation les poids moyens sont de 2013,86 g (lot 0), 2065,51 g (lot 1), 2169,67 g (lot 2); 2110,47 g (lot 3) et 2102,14 g (lot 4). Le lot ayant recu de la virginiamycine (lot 4) eut la consommation la moindre (3,592 kg) et la meilleure conversion (1,75 kg de nourriture pour 1 kg de gain corporel). En conclusion l'addition de jus de rumen lyophilise augmente le poids des poulets de chair et ameliore la conversion.

Six male, Merino sheep were utilized in a 6 X 6 Latin square design. The rations were prepared as standard protein and standard energy level /(S-Group 1); low energy (LE-Group 2); low protein (LP-Group 3); high protein (HP-Group 4); high energy (HE-Group 5) and 10 g/day bicarbonate added to the high energy (HE+HCO 3-Group 6). The experimental period extended to 10 days feeding period for each ration. Rumen fluid samples were taken from animals 0 hours before feeding as well as in the 2 nd and the 4 th hours after feeding during the last two days of feeding period. The end of the experiment time and feed factor showed statistically significant differences in pH values (P<0.05). The lowest pH level was observed in sheep fed ration HE+HCO 3 before feeding time and pH levels were not statistically significant in the 2 nd and 4 th hours after feeding. It was found that the ammonia level in animals fed HP ration was the lowest (P<0.05) before feeding. Differences among time factors were found to be statistically significant (P<0.05) before feeding and 4 th hours after feeding. Among the protozoa species Entodinium minimum was the most common species. Differences among feed factors for Entodinium caudatum level are found to be statistically significant (P<0.05).

The study was conducted to determine the effects of glucose treatment of canola meal (CM) and canola seed (CS) on rumen degradability characteristics of dry matter (DM), organic matter (OM) and crude protein (CP) in four ruminally cannulated mature (2 years old) Merino rams. Canola meal and canola seed were treated first with water then heat, treated first with water then heat plus 2% glucose and treated first with water then heat plus 3% glucose. Crude protein degradability value of CM was reduced (p<0.001) by 3% glucose treatment at all rumen incubation times. Effective DM and OM degradabilities of CM were decreased (p<0.001) by 2 and 3% glucose treatments. Effective crude protein degradability of CM treated with 3% glucose was lower (p<0.001) than untreated CM, CM treated with water+heat and 2% glucose. While effective DM (p<0.05) and OM (p<0.001) degradabilities were reduced only in CS treated with 3% glucose, this effect was not determined for effective ...

The DM of meals was determined by drying at 105°C for 24 h, and sufficient water or mixtures of water and xylose (0.5 and 1%) were added to increase the moisture content of SBM and CSM to 25% (McAllister et al., 1993). These meals were thoroughly mixed with each solution and heated for 2 h at 100°C in a convection air oven. Trial 1 Three ruminally cannulated Merino rams aged 1.5 years weighing approximately 60 kg were fed twice daily (at 09.00 h and at 16.00 h) with a ration containing 200 g concentrate (barley, 51%; sunflower meal, 25%; wheat bran, 21%; salt, 1%; dicalcium phosphate, 1% and vitamin+ mineral premix, 1%) and 1.000 g alfalfa hay. Nylon bag technique was used to measure disappearance of DM, OM and CP in the rumen of untreated and treated SBM and CSM. Nylon bags (45 µm pore size; 9×14 cm bag size)

The study was conducted to determine the effects of xylose treatment of soybean meal (SBM), full fat soybean (FFSB) and soybean seed (SBS) on rumen degradability of dry matter (DM) and crude protein (CP) in four ruminally cannulated two years old Merino rams. These feedstuffs were treated with water + heat, water + heat + 2% xylose or 3% xylose. Xylose treatments at both levels (2% and 3%) decreased (p<0.001) effective degradability values (Pe) of DM and CP in SBM. Although the calculated reduction coefficients for effective CP degradability values of SBM treated with 2% and 3% xylose (37% vs 41%) were similar, they were different compared to that of untreated SBM. The calculated reduction coefficients for effective CP degradability values of FFSB and SBS treated with 2% and 3% xylose were 15.6% and 25%; 25.8% and 28.3, respectively. In conclusion, xylose treatment is more effective on protection of SBM proteins from rumen degradation compared to FFSB and SBS proteins wh...

In this study, Merino rams with ruminal fistulas were used (n = 4) to determine the effect of glucose treatment of soybean meal (SBM), full fat soybean (FFSB) and soybean seed (SBS) on the ruminal degradability of dry matter (DM) and crude protein (CP). All these feedstuffs were grinded, diluted with water and heated (2 h; 100 degrees C) either without or with supplementation of 2 or 3% glucose (20 or 30 g glucose per kg dry feed). For the determination of the ruminal degradability nylon bag technique was used (incubation times: 2-48 h). In general ruminal degradability of protein in all three soy products was reduced by glucose treatment. In FFSB CP disappearance ...
