Red Ginger

Red ginger is herb that commonly used as part of traditional medicine due to its essential oil content. Some essential oil have proven as rumen fermentation modifier. Addition of red ginger in ruminant diet was studied using in vitro gas production technique to evaluate its effect on nutrient digestibility. Red ginger meal was added to meet essential oil level in fermentation medium of 0 mg/l as control, 25, 50, 75 and 100 mg/l. The diet consisted of Penisetum hybride, rice bran, wheat pollard in ratio 60:20:20 DM basis. Feed fermentation was incubated for 24 h at 39°C. At the end of incubation data of gas production volume was taken, and residual feed were collected for further nutrient analysis to calculate the digestibility of dry matter (DM), organic matter (OM), crude protein (CP) and crude fiber (CF). Variance analysis was used to analysis collected data, followed by DMRT analysis.  Addition of red ginger increase total volume of gas production at level 50 mg/L and above. DM and OM digestibility did not affected by red ginger addition whereas CP digestibility were significantly decreased start at level 50 mg/l. In contrast, CF digestibility of treatment level of 50 mg/l significantly higher than control. In conclusion, addition of red ginger correspond to level essential oil of 50 to 100 mg/l improve ruminal nutrient fermentation.

Context Feeding ruminants with fresh cassava roots (FCR) is limited because they have a high concentration of hydrocyanic acid (HCN). Thus, it was hypothesised that receiving a feed block containing high sulfur (FBS) would reduce hydrocyanic acid (HCN) in FCR and improve rumen fermentation and nutrient digestibility in animals. Aims The goal of the present work was to study the influence of the ratio of FCR to rice straw (RS) together with FBS on kinetics of gas production, HCN concentration, fermentation characteristics and nutrient digestibility, using in vitro technique. Methods The experimental design was a 4 × 2 factorial arrangement in a completely randomised design, with three replications per treatment. Factor A was the FCR to RS ratio, which was 100:0, 60:40, 40:60 or 0:100. Factor B was sulfur, which was provided as two concentrations in FBS (2% and 4% DM). Gas production was recorded after incubation, at 0, 0.5, 1, 2, 4, 6, 8, 12, 18, 24, 48, 72 and 96 h. Fermentation liquor was collected and determined for kinetics of gas production, HCN concentration, fermentation characteristics and nutrient digestibility. Key results Cassava root to RS ratio influenced the cumulative gas production after 96 h. Inclusion of sulfur in the FBS at 4% increased the cumulative gas production, when compared with inclusion at 2%. The gas production from degradable fraction (b) and the rate of gas production (c) were significantly different among the treatments with different FCR:RS ratios, whereas there was no difference between using 2% and 4% sulfur in the FBS. The HCN concentration in fermentation liquor increased with an increasing proportion of FCR. Furthermore, inclusion of sulfur in the feed block at 4% reduced HCN concentration by 42.8%, when compared with inclusion at 2% (P < 0.05). Ammonia-nitrogen concentration was significantly different among the FCR:RS-ratio treatments and was reduced when the proportion of FCR was decreased (P < 0.05). In vitro digestibility was significantly increased with an increasing proportion of FCR. Increasing the proportion of FCR with 4% of sulfur in the FBS significantly increased in vitro DM digestibility, compared with 2% sulfur. Increasing the FCR:RS ratio with 4% of sulfur in the FBS increased the proportion of propionic acid (P < 0.05). Conclusions Using a high FCR:RS ratio (100:0 or 60:40) with 4% sulfur in the FBS enhanced kinetics of gas production, propionic molar proportion, nutrient digestibility, and HCN detoxification by rumen microbes in an in vitro trial. Implications An in vivo study should be encouraged to verify the results and obtain more data.

Abstract The purpose of this study was to investigate the effect of adding various levels of waste sour lemon pomace to lucerne on the properties and ruminal gas production of silage. Levels of 0 (Control), 25 (L1), 50 (L2), 75 (L3), and 100 (L4) % lemon pomace were replaced by lucerne for silage preparation and silenced for 60 days. The experiment was conducted in a completely randomized design with three replications (3 silos per treatment). After opening the silos, pH and dry matter were measured immediately, and the dried samples were kept at -20 until further tests. The silage pH decreased with the addition of lemon pomace compared to the control (p < 0.05). Total silage volatile fatty acids and dry matter content increased with adding lemon pomace. The results of gas production also showed that lemon pomace increased the in vitro gas production volume. Adding lemon pomace to lucerne silage due to the high pectin content in these agricultural wastes caused a rapid decrease of silage pH and an acidic environment. It prevented the growth of non-beneficial bacterial species. The obtained data showed that waste sour lemon has a good potential to use as a livestock feedstuff that can be useful in reducing the cost of ruminant production and preventing environmental pollution.

Endophytic fungi isolated from red ginger (Zingiber officinale) can inhibit growth of Fusarium oxysporum, but the ability of the fungi to control Candida albicans  as human pathogen has not been reported. The aims of this research were to study the mechanism of ten endophytic fungi isolates derived from red ginger to control C. albicans in vitro using dual culture methode and fungal extract, and to determine fungal bioactive chemical groups produced by the fungi. Three out of ten isolates tested, Talaromyces assiutensis JMa 7, T. assiutensis JMbt 3, and Curvularia affinis JMbt 9 inhibited growth of C. albicans with inhibition zones were 4.0 mm, 4.9 mm, and 11.3 mm, respectively. The cultures of the three potential endophytic fungi were extracted by maceration method using 3 solvents i.e ethyl acetate, n-hexane and ethanol. The three isolates were grown in PDB separately for 21 days incubation. At harvest, the culture filtrate was extracted by ethyl acetate and n-hexane, while fungal mycelia were extracted by all the three solvents. Ethyl acetate extracts obtained from culture filtrate of all the three fungal isolates consistently inhibited C. albicans with inhibition zones were 2.0-3.8 mm. For n-hexane extract, however, only Talaromyces assiutensis JMbt 3 that had positive effect with inhibition zone was 2.0 mm. All extracts from mycelia did not have any effects on C. albicans. The ethyl acetate extract of T. assiutensis JMbt 3 was analysed to determine its chemical groups using visible color on thin layer chromatography (TLC). The results showed that the bioactive compounds was terpenoids, and antioxidant.

Indigofera Zollingeriana

This study was conducted to evaluate the fermentability and nutrient digestibility of concentrate feed containing Indigofera zollingeriana using in vitro technique. Randomized complete block design was used on 3 types of concentrate feed and 4 groups (replicates) of goat's rumen liquid. The concentrate feeds were R1, R2 and R3 containing I. zollingeriana at 0 (control), 20 and 40%, respectively. Variables observed were total gas production, in vitro dry matter digestibility (IVDMD), organic matter (IVDOM), and crude protein (IVDCP), volatile fatty acid (VFA) profiles and NH3 concentration. Data were analyzed using analysis of variance (ANOVA). Results showed that there was no significant effect of R3 on IVDMD, IVDOM and IVDCP as compared to R1 and R2. However, there was significant difference (P<0.05) of the parameters between R1 and R2 (P<0.05). There was no significant effect (P<0.05) of different Indigofera levels on total gas production. The partial VFA of each concentrate feeds was not significantly different, but the percentage of acetic acids of concentrates containing I. zollingeriana were higher than those of control (P<0.05). The concentration of rumen NH3 of R2 was lower than R1 and R3 (P<0.05) even though the IVCPD of R2 was higher than R1. It could be concluded that the inclusion of I. zollingeriana as concentrate feed ingredient at 20% maximum level .
