ABSTRACT The aim of the current experiment was to evaluate the chemical composition, metabolizable energy (ME), organic matter digestibility (OMD), gas and methane production of some legume plants estimated by in vitro gas production technique, and to determine the relationship among chemical composition, ME, OMD, gas and methane production of some legume plants. Although species has a significant effect on the chemical composition, gas production, ME and OMD species has no effect on methane emission of legume hays. Neutral detergent fibre (NDF) and acid detergent fibre (ADF) ranged from 22.86% to 42.93% and 20.24% to 37.16% respectively. Crude protein (CP) contents of legume hays ranged from 13.61% to 20.55%. Neutral detergent fibre and ADF contents of legume plants are negatively correlated with gas production, ME and OMD. It can be concluded that legume plant studied in the current experiment showed a wide nutritional diversity and will provide not only protein but also fibre for livestocks. They may exhibit complementary role for ruminant animals grazing on poor quality forages. Legume species studied in the current experiment had a no anti-methanogenic properties.

The aim of the present study was to compare the leaves of Liquidambar orientalis with leaves of Laurus nobilis and Eucalyptus globulus in terms of chemical composition and anti-methanogenic potentials using the in vitro gas production technique. Species had a significant effect on the chemical composition, gas production, methane production, metabolisable energy and organic matter digestibility of tree leaves. Crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and condensed tannin (CT) contents of tree leaves ranged from 9.11 to 12.8, 22.49 to 35.85 and 32.76 to 49.31, 1.55 to 9.29% respectively. Gas production, methane production, metabolisable energy (ME) and organic matter digestibility (OMD) ranged from 21.72 to 31.54 ml, 2.62 ml to 4.41 ml, 6.62 to 9.24 MJ /kg DM, 41.23 to 54.84 % respectively. It is likely that leaves of Liquidambar orientalis will be more effective for methane mitigation in ruminant animals as compared with Eucalyptus globules and Laurus nobilis. However before large implication it should be tested in vivo to evaluate the effect of leaves of Liquidambar orientalis on animal production

The objective of this experiment was to determine the effect of peppermint essential oil on in vitro gas, volatile fatty acids (VFA), methane, ammonia production, metabolisable energy (ME) and organic matter digestibility (OMD) of barley grain. Gas productions of barley grain were determined at 3, 6, 12, 24, 48, 72 and 96 h incubation times in the presence (100, 200, 400, 800 and 1200 mg/L) and in the absence of peppermint essential oil. The supplementation of peppermint essential oil significantly (P < 0.001) reduced the total gas production (A), ME, OMD, total VFA, methane and ammonia production. The mean decreases in A, OMD, ME, total VFA, methane and ammonia production of barley grain were 0.0338, 0.0341, 0.0054, 0.041, 0.023 and 0.0079 units per mg peppermint essential oil supplementation, respectively. In conclusion, the current study has provided significant information on the anti-microbial activity of peppermint essential oil causing an inhibition of the overall fermentation process of barley grain. Therefore, before large scale implementation, further investigations are required to determine the effect of peppermint essential oil on voluntary food intake, animal performance and the profitability of the supplementation in vivo.

The aim of this study was to determine the potential nutritive value of cotton gin trash obtained from five different companies using chemical composition and in vitro gas production technique. There was considerable variation among cotton gin trash obtained from five different companies in terms of chemical composition and in vitro gas production, metabolizable energy (ME) and organic matter digestibility (OMD). The crude protein (CP) contents of cotton gin trash ranged from 6.59% to 12.55% on dry matter (DM). Neutral detergent fibre (NDF) and acid detergent fibre (ADF) contents ranged from 49.24 to 62.22% on DM and 40.73 to 48.31% on DM respectively. The gas production ranged from 22.91 to 33.51 ml of 200 mg of DM after 24-h incubation. The ME and OMD contents of cotton gin trash ranged from 5.38 to 7.09 MJ/kg DM and 37.44 to 52.69% respectively. In conclusion, chemical characterization of CP, OMD and ME suggests that the cotton gin trash moderate level of CP concentration and was digestible therefore it could be said that cotton gin trash will provide roughage of an acceptable quality for ruminant animals.

The aim of this study was to determine the potential nutritive value of pistachio hulls obtained from six different varieties using chemical composition and in vitro gas production technique. In vitro gas productions of pistachio hulls were determined at 0, 3, 6, 12, 24, 48, 72 and 96 h incubation times and their gas production kinetics were described. There is considerable variation among pistachio hulls obtained from six different varieties in terms of chemical composition and in vitro gas production, metabolisable energy (ME) and organic matter digestibility (OMD). Dry matter (DM) contents of pistachio hulls ranged 26.45 to 29.25%. Ash content of pistachio hulls ranged from 8.50 to 19.86%. The crude protein (CP) contents of pistachio hulls ranged 7.27 to 14.99%. The hulls from Kırmızı, Ohadi and Keten Gömlegi (KG) had significantly higher CP contents than the others. The NDF and ADF contents of pistachio hulls ranged from 18.25 to 22.49% and 14.32 to 18.29% respectively. The pistachio hulls from Ohadi and Uzun had significantly higher NDF and ADF contents than the others. The CT contents of pistachio hulls ranged from 2.03 to 2.63%. The hulls from Beyaz Ben (BB) had significantly higher CT content than that of KG. The gas production rate ranged from 0.071 to 0.107%. The gas production rate of pistachio hulls from Sultani and KG were significantly higher than the others. The potential gas production of pistachio hulls ranged from 65.92 to 73.46 mL. The potential gas production of pistachio hulls from BB and Ohadi were significantly higher than the others. The ME and OMD contents of pistachio hulls ranged from 9.76 to 11.05 MJ/kg DM and 69.00 to 74.50% respectively. The ME contents of pistachio hulls from BB and Ohadi were significantly higher than those of Kırmızı, Uzun and KG whereas the OMD contents of pistachio hulls from Ohadi were significantly higher than those of pistachio hulls for Kırmızı, Sultani, Uzun and KG. In conclusion, chemical characterization with CP, OMD and ME suggests that the pistachio hulls had moderate level of CP concentration and was quite digestible therefore it can be said that pistachio hulls will provide feedstuffs of an acceptable quality for ruminant animals.

Summary The potential nutritive values of acorns of Quercus suber, Quercus branti, Quercus coccifera, Quercus cerris and Quercus infectoria were estimated by chemical composition and in vitro gas production technique. Acorns collected at least 10 different trees in three experimental plots. There were significant (P 0.5) differences in the potential gas production of acorn among oak species when incubated in the absence of PEG, there is significant (P<0.001) differences in the potential gas production of acorn among oak species when incubated in the presence of PEG. Although the estimated organic matter (OMD) and metabolisable (ME) contents of acorn for Q. suber and Q. infectoria were significantly (P<0.001) higher than those for Q. branti, Q. coccifera and Q. cerris when incubated in the absence of PEG, the estimated OMD and ME contents of acorn for Quercus cerris and Q. infectoria were significantly lower than those for Q. suber, Q. branti and Q. coccifera when incubated in the presence of PEG. The improvement in gas production, OMD and ME in the presence of PEG emphasizes the negative effect of tannins on digestibility. As a conclusion, oak acorns have potential nutritive values for ruminant animals such as sheep and goat since acorns have high starch, OMD and ME but low level of CT contents. However these results obtained in the current study should be supported by in vivo feeding experiments.
