In Vitro Gas Production

This study was carried out to determine the nutritional value of some selected peanut varieties and line in the Eastern Mediterranean Agricultural Research Institute of Adana, Turkey. The peanut varieties used were Gazipasa, Sultan, NC7, Cihangir, and Halisbey; while the peanut line was DA335/2011. The chemical composition, metabolizable energy (ME), net energy lactation (NEL) and organic matter digestibility (OMD) of the selected peanut varieties and line were determined through Hohenheim in vitro gas production technique. Incubation times for Hohenheim gas production technique were 3, 6, 9, 12, 24, 48, 72 and 96 hours. The analysis of variance (General Linear Model) was carried out using the SPSS package program. The differences among groups in terms of nutrient contents were found to be significant (P<ou=0.05), except for dry matter (DM) and hemicellulose (HC). The highest crude protein (CP) (40.13%) was found in Sultan variety, while the crude oil (CO) content was found to be between 21.32 and 31.01%. The ADF, NDF, and ADL content of the peanut varieties and line were within the ranges of 2.32-7.91%, 4.85-9.88%, and 0.43-2.62%, respectively. Conversely, the Sultan variety had the highest crude cellulose (CC) value, Cihangir variety was determined to contain the highest hemicellulose (HC) value. The differences in 24 hour gas and methane production among different peanut varieties and line were found to be not-significant. (P > 0.05).

Tridax Procumbens

Studies were conducted to evaluate the nutritive value of eight selected forages (Tridax procumbens, Merremia aegyptia, Aspilia africana, Tithonia diversifolia, Alchornea cordifolia, Alchornea laxiflora, Synedrella nodiflora, and Newbouldia laevis) consumed by ruminants in South-Western Nigeria. Chemical composition and qualitative analysis of saponins, phenol and steroids of the plants were determined. In vitro gas production (IVGP) was carried out for 72 hours on the plants. Metabolizable energy (ME), Organic matter digestibility (OMD) and Short chain fatty acids (SCFA) were predicted and methane (CH4) was measured. Five of the plants were subjected to acceptability study using cafeteria method. The result of the chemical composition revealed that M. aegyptia had the highest value of CP (22.09 %) while Tridax procumbens had the lowest (10.50 %). A. africana had the highest content of Calcium, Phosphorus and Zinc with values of 3.10 %, 0.93 % and 39 ppm respectively. The analysis of secondary metabolites showed that A. africana, T. diversifolia and S. nodiflora were high in saponin while A. cordifolia, A. laxiflora, T. diversifolia and A. africana were implicated for condensed Tannin. N. laevis recorded a high level of steroids. Results showed significant variations in the values of IVGP, ME, OMD, SCFA and CH4 obtained for the plants. The order of preference of the plants by the calves were M. aegyptia>A. cordifolia > N. laevis > A. axiflora> T. diversifolia. The study revealed that the forages are rich in crude protein as well as micro and macro minerals. They are also rich in highly fermentable carbohydrates which affirm them as ruminant feed resource.

Abstract Twelve feedstuffs (cereals, fibrous byproducts, protein-rich byproducts and forages) were determined for methane (CH4) production by the in vitro gas production technique (IVGPT) and were correlated with their chemical compositions to predict enteric CH4 originating from these feedstuffs in ruminants. Corn, soybean hull, soybean meal and corn silage generated the highest CH4 production from their respective categories. The average CH4 production of fibrous byproducts (44.6 ml/g DM incubated) was significantly higher than that of cereals (40.3 ml/g DM incubated), forages (33.3 ml/g DM incubated) and protein-rich byproducts (31.0 ml/g DM incubated) after the 48-h incubation (P≤0.05). The highest average total volatile fatty acid (VFA) concentration was determined in cereals (53.6 mM). The acetate to propionate ratio was significantly lower in cereals when compared with other categories of feedstuff (P≤0.05). The correlation analysis showed that in vitro true digestibility (IVTD) positively correlated with the CH4 production in all four categories of feedstuffs (P≤0.05). The neutral detergent fiber (NDF) and acid detergent fiber (ADF) content positively correlated with CH4 production in every category of feedstuffs except cereals. The starch content negatively correlated with CH4 production for fibrous and protein-rich byproducts (P≤0.05), but it positively correlated with CH4 production for forages (P≤0.05). The CH4 production was predicted more accurately by the equations proposed for each category (R2=0.944, 0.876, 0.942 and 0.915 for cereals, fibrous and protein-rich byproducts and forages, respectively) than for the unclassified feedstuffs (R2=0.715). In conclusion, the contribution of individual chemical composition to CH4 production differed depending on the category of feedstuffs. The precision of CH4 prediction could be substantially improved by classifying feedstuffs into categories according to their chemical composition, and selecting the appropriate predictors for each category. Information about the CH4 output of these feedstuffs will be useful in formulating low CH4-producing diets for ruminants.

Ad Libitum

The in vivo determination of methane (CH4) production requires specialist equipment which is costly to maintain. Whilst the in vitro gas production technique has been demonstrated to show potential to rank diets for their methanongenic potential at maintenance planes of nutrition (Moss and Givens, 1997) no study has investigated this relationship when feedstuffs are fed ad libitum. The objective of this study was to assess the ability of the technique to predict in vivo CH4 production and animal performance from six diets differing in their chemical composition.

The purpose of this study was to compare the chemical composition, metabolizable energy, net energy lactation, total digestible nutrient, in vitro digestion parameters, and relative feed quality of some grass forage plants growing naturally in the meadows and pastures of Erzurum province in Turkey. Orchardgrass (Dactylis glomerata), Variegated brome (Bromus variegatus), and Intermediate wheatgrass (Agropyron intermedium) were used as the research material. In this study, the metabolizable energy (ME) and net energy lactation (NEL) contents of the green grass crops forage plants were determined by in vitro gas production method, and their digestibility parameters and relative feed quality (RFQ) by the neutral detergent fiber (NDF) procedure using an Ankom Daisy incubator. As a result of the study, the differences between the forage plants were found to be statistically significant in terms of chemical composition, metabolizable energy, net energy lactation, true organic matter digestibility (TOMD) and RFQ (P<0.05). While the green intermediate wheatgrass was found to have the highest crude protein (CP) (19.56%), crude fat (CF) (3.06%), dry matter (DM) (9.14%), ME  (8.82%), NEL (5.42%), and TOMD (97.75%); the green variegated brome was found to have the highest RFQ (149.79). The green orchardgrass was found to have the highest contents of neutral detergent fiber (NDF), acid detergent fiber (ADF), and acid detergent lignin (ADL) with 66.23%, 34.14, and 8.52%, respectively. In conclusion, the green grass forage plants examined in this study can be used to eliminate the quality roughage deficit.

Guinea Grass

The experiment was conducted to determine the nutritive value of ensiled guinea grass with different additives using in-vitro gas production method. The silage were in 5 treatments T1: 90% of guinea grass + 10% yellow maize residue, T2: 90% of guinea grass + 10% white maize residue, T3: 90% of guinea grass + 10% guinea corn residue, T4: 90% of guinea grass + 10% soy bean residue, T5: 100% of guinea grass.. The silage quality, physical properties, chemical composition, the in vitro gas production after 24hours of incubation were investigated. Methane (CH4) gas produced was measured. Metabolizable energy (ME), Organic matter digestibility (OMD) and the short chain fatty acid (SCFA) were estimated from the in vitro gas production parameters. The colour of the silage varied among the silage treatments and were closer to the colours of the fresh forage. All the silage had pleasant smell and the temperature had no significant difference among the silage treatments. The pH ranged from 4.23 � 5.60 which has significant difference among the silage treatments. The chemical composition of the silage were as follows: Dry matter (DM) 23.73 to 29.50%, Crude protein (CP), 6.93 to 11.05%; Crude fibre (CF), 27.84 to 31.20%; and ash, 15.01 to 17.50%. Hemicellulose ranges from 23.29 to 26.05%, Cellulose ranges from 21.07 to 30.50%. The mineral composition value of the ensiled ranges are as follow: CA, 0.19 to 0.23%; P, 0.17 to 0.19%; NA, 0.08 to 0.11%; k, 0.34 to 0.45%; MG, 0,10 to 0.13%. Potential gas production varied from 13.00 ml/200mg DM to 18.67 ml/200mg DM. The high (P<0.05) potential gas value of 18.67 ml/200mg DM was obtained for silage T4. The highest value of ME (5.41MJ/kg DM); OMD (46.10%) and SCFA (0.51-mol) were obtained in silage T3 which contain 90% guinea grass with 10%guineacorn residue. Result indicates that silage from 90% guinea grass with 10% white maize residue have the best nutritive value.
