Organic matter (OM), neutral detergent fibre (NDF) digestibilities and metabolizableenergy content of some available agro-chemicals wastes (AIW) such as dry brewer's grain cocoa shell, cocoa dust, dessicated cocnut waste meal, wheat bran and rice bran used as ruminant feeds were setimated from in vitro gas production technique. Their crude protein (CP) content varieted from 13.7-25.6%, NDF ranged from 21.9-48.4% Om from 88.6-95.4% and non structural carbohydrates (NSC) estimates increased from 7.2 - 45.6%. Dessicated coconut waste meal(DCWM) had the lowest NSC content. Nutrient contents varied among AIW. Net gas production ranged from 7.7-23.1 ml/day and significant differences (P<0.05) were observed among the AIW in net gas production. The lowest and highest gas productions were obtained in cocoa dust (CD) and wheat bran (WB) respectively. Om digestibility  also had higher ME values showed significantly the differences between the AIW. AIW with high OM digestibility also had higher ME values. Finally the investigation demonstrated that available AIW in the pacific Island countries have potential as animal feedstuffs

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).

An experiment was conducted to quantify the chemical composition, different forms of tannins and their effects on in vitro gas production, organic matter digestibility and metabolisable energy content in Syzigium cumini (Blackberry) seed with and without polyethelene glycol (PEG). The DM, OM, ash, CP, NDF and ADF contents of S. cumini seeds were 90.1, 87.6, 2.6, 4.6, 32.9 and 15.5%, respectively. The total phenol, total tannin, condensed tannin and hydrolysable tannin content were 5.89, 4.25, 0.42 and 0.05mg/g seed, respectively. In vitro gas production, organic matter digestibility and metabolisable energy content of S. cumini seed were 54 ml, 42.91% and 6.43 MJ/Kg DM, respectively. Addition of PEG to tannin containing seed was significantly (P<0.05) increased in vitro gas production, OMD and ME content. Higher levels of tannins in S. cumini seed could limit utilization through impaired digestibility and nutrient utilization but the addition of PEG increased all the fermentation parameters studied. It is predictable from the present findings that S. cumini seed could be utilized as natural source of feed additives to alter rumen fermentation parameters especially to protect protein and other nutrients from ruminal degradation, thereby make the nutrients available in the lower tract for higher milk and meat yield.Progress.

The present study was planned to evaluate the chemical composition and nutritive values of commonly available pulse chunies of Green gram (GGC), Black gram (BGC), Bengal gram (BnGC) and Red gram (RGC) available in the local markets of Hyderabad, Andhra Pradesh. These chunies were subjected to chemical analysis followed by measurement of in vitro gas production (IVGP) with sheep rumen liquor. By calculation, in vitro organic matter digestibility (IVOMD), total digestible nutrient (TDN), Metabolizable Energy (ME) was determined. DM (P<0.001), CP (P<0.001), CF (P<0.001), TA (P<0.001), NDF (P<0.001), ADF (P<0.001), cellulose (P<0.01), hemicelluloses (P<0.001), lignin (P<0.01) silica (P<0.001) and Ca (P<0.05) varied significantly. The cumulative gas production in IVGP technique at 0-2, 0-4, 0-6, 0-8, 0-12 and 0-18h incubations varied significantly. The TDN and ME content were highest (P<0.01) in GGC. IVOMD (mg/24h) was comparable (P>0.05) among them. The study concluded that these chunies are good energy sources. GGC was the best with respect to its energy and organic matter digestibility among these. High protein and energy contents of BGC and GGC signified that these can be a good feed replacement of concentrates for livestock feeding.

The gas production (GP) technique has previously been used to estimate the gas volume (fermentable energy (FE)) of compound feed ingredients for ruminants (Newbold et al., 1996). It was shown that the FE content of feed mixtures was represented by the combination of the total gas from the incubation of the individual feeds. However this additivity might not be consistent throughout the incubation period. The objectives were to test whether 1. other GP parameters give better estimates of FE for simple mixtures and are they additive; 2. whether organic matter apparently degraded in the rumen (OMADR) explain differences in GP; and 3. to find out if there are any other better measures than OMADR for estimating FE.

Abstract The aim of the research was to evaluate the effect of three Eucalyptus globulus extracts rich in phenolic compounds, especially flavonoids, on rumen fermentation, methane (CH4) production, organic matter degradability and protozoa population using an in vitro gas production technique. Four concentrations (0, 50, 75 and 100 mg) of three Eucalyptus extracts (ethyl acetate, n-butanol and aqueous) were added to a diet of ruminants (forage: concentrate ratio 60:40) and incubated at 39°C under anaerobiosis with buffered rumen fluid. After 24 h, the fermentation fluid was analysed for ammonia-N and volatile fatty acids (VFA). Organic matter degradability (OMD) and protozoa were also determined; in vitro gas production was also recorded and CH4 concentration was measured. Compared to the control, CH4 production was significantly lower for ethyl acetate extract (P<0.05), but higher for n-butanol and aqueous extracts. Production of ammonia- N was lower in all Eucalyptus extracts (P<0.05). Propionate production (P<0.05) increased for ethyl acetate and n-butanol extracts, whereas no effect was registered for VFA, for all Eucalyptus extracts. Ethyl acetate extract decreased in vitro OMD (P<0.05), whereas n-butanol and aqueous extracts were comparable to the control. Protozoa population decreased (P<0.05) for all extracts in comparison with the control. Eucalyptus ethyl acetate extract might be promising to be used as a potent anti-methanogenic additive. Moreover, the assessment of the right dosage seems to be important to decrease methane production, without reducing feed nutritional value.
