<p>This experiment was performed to investigate the effects of some essential oils on chemical properties and aerobic stability of lucerne silage. Treatments included lucerne silage without additives (control), lucerne silage with 60 mg cinnamon essential oil/kg, lucerne silage with 60 mg flaxseed essential oil/kg, lucerne silage with 60 mg lemon seed essential oil/kg, lucerne silage with 180 mg blend of essential oils (60 mg cinnamon + 60 mg flaxseed + 60 mg lemon seed essential oils/kg).<strong> </strong>Adding essential oils to lucerne silage reduced silage pH (<em>p </em>&lt; 0.001) compared to control. The highest level of total volatile fatty acids (tVFA) was found when lemon seed essential oil and the lowest level when flaxseed essential oil was used. The lucerne silages treated with essential oils had the highest crude protein contents (<em>p </em>&lt; 0.01). Untreated lucerne silage had the highest level of gas production compared to lucerne silage treated with lemon seed and flaxseed essential oils (<em>p </em>&lt; 0.01). The essential oil additives increased the aerobic stability of the silage. It can be concluded that the use of essential oil additive in the preparation of high quality lucerne silage, can improves the quality and nutritive value of silages.</p>

AbstractFinding new fodder resources with moderate to high nutritional value that are cheaper and available is one of the most challenges in livestock industries. Hence, the nutritive value of some tree leaves (quince, pear, olive, mirabelle plum, greengage, sour cherry, and persimmon) was investigated by different laboratories and in vitro methods. Also, partial substitution of alfalfa and corn silage (50%) with these leaves was investigated using forty-eight goats in a randomized complete block design in vivo. Highest total phenol and tannin contents were obtained in quince (p < 0.001). Greengage (146.37 g/kg DM) and persimmon (136.96 g/kg DM) exhibited the highest crude protein, respectively (p < 0.001). Calcium content (19.82 g/kg DM) was highest in persimmon leaves (p < 0.001). Greengage (66.07 mmol/L) and mirabelle plum (65.58 mmol/L) produced more total volatile fatty acids in the culture medium, respectively (p < 0.001). Potential gas production ranged from 39.65 mL for pear to 55.32 mL mirabelle plum. Sour cherry had the highest acid–base buffering capacity (183.73 mEq × 10–3, p < 0.001). Highest dry matter intake (1087 g/day) and crude protein digestibility (70.80 %) were observed in diets containing greengage (p < 0.001). Total antioxidant capacity of serum increased when olive, quince, and persimmon were considered in goats feeding (p < 0.001). Although all studied leaves can be fed in diets of goats without deleterious effects on performance, serum, and hematology parameters, in vivo and in vitro results indicated that greengage in terms of nutritive value was superior to other studied leaves.

The aim of the present study was to evaluate the impact of essential oils (EO) from Lippia turbinata (LT) and Tagetes minuta (TM) as well as the rotation of both EO on fermentation parameters in vitro. Daily addition of LT, TM, or a 3-day rotation between them (TM/LT), as well as a control (without EO), was evaluated using the rumen simulation technique (Rusitec). The experiment lasted 19 days, with a 7-day adaptation period, followed by 12 days of treatment (Days 0–12). The EO were dissolved in ethanol (70% vol/vol) to be added daily to fermenters (300 μL/L) from Day 0. Daily measurements included methane concentration, total gas production, apparent DM disappearance and pH, which started 2 days before the addition of treatments. On Days 0, 4, 8 and 12 apparent crude protein disappearance and neutral detergent fibre disappearance, ammonia and volatile fatty acid concentration and composition were determined. Methane production was significantly inhibited shortly after addition of both EO added individually, and persisted over time with no apparent adaptation to EO addition. The TM/LT treatment showed a similar effect on methane production, suggesting that rotating the EO did not bring further improvements in reduction or persistency compared with the inclusion of the EO individually. Gas production, total volatile fatty acid concentration and composition and apparent crude protein disappearance were not affected by EO addition. Compared with the control, a 5% reduction of apparent DM disappearance and a 15% reduction of neutral detergent fibre disappearance were observed with the addition of EO. Only TM and TM/LT reduced ammonia concentration. Given the significant and persistent antimethanogenic activity of both EO, and the potential of T. minuta to modify nitrogen metabolism, EO from these plant species are of interest for developing new feed additives with potential application in ruminant nutrition that are also likely to be acceptable to consumers.

AbstractEmulsion is an efficient encapsulation tool for enhancing the functional properties of essential oils (EOs). Herein, two two-dimensional cinnamon essential oil emulsions (from micro- to nanoscales) were emulsified by hydroxypropyl methylcellulose, and their antimicrobial and physicochemical properties were investigated. For the models of Escherichia coli CGMCC 1.0907, Salmonella enterica subsp. Enterica serovar Typhi (CICC 10867), Staphylococcus aureus CGMCC 1.0089, and Listeria monocytogene CGMCC 1.9144, the minimum inhibitory concentration (MIC) of the nanoemulsion was 31.25 μL/mL compared to that of the microemulsion (62.5–125 μL/mL) and pure oil (125–250 μL/mL), indicating the superiority of nanoemulsion as an antibacterial agent. The results showed that the highest activity was seen in the gram-positive L. monocytogenes whereas the lowest was in the gram-negative S. enterica. The identified properties of HPMC (hydroxypropyl methylcellulose) provide the potential for emulsifying and enhancing essential oils in light industries, especially for food processing.

Abstract: The objective of this work was to evaluate the effects of re-ensiling and bacterial inoculation on the quality of corn silage. The experiment was carried out in a 2x2 factorial design with or without inoculant (association of Lactobacillus plantarum and Propionibacterium acidipropionici), and with re-ensiling after 36 hours of aerobic exposure or only ensiling of the whole plant of 'BRS 1055' corn. The fermentative quality, nutritional parameters, dry matter losses, aerobic stability, and microbiological counts of silages were evaluated. Re-ensiling caused an increase of pH and in acetic acid and propionic acid concentrations, as well as in the dry matter (DM), crude protein, neutral detergent fiber, and neutral detergent fiber crude protein contents. Conversely, there was a reduction in the nonfiber carbohydrates concentration and in in vitro dry matter digestibility for the re-ensiled material. All changes were explained by the higher-effluent production and DM loss of re-ensiled material that was subjected to two compactions. Microbiology was not altered by the treatments. The use of inoculant altered ash content, but it did not influence other parameters. In contrast, re-ensiling after 36 hours of aerobic exposure caused a reduction in the nutritive value of corn silage and accentuated the DM losses.

This study is a part of the valorization of extract from three most commonly used Algerian spices, namely; caraway and cumin seeds and cinnamon bark. On the one hand, it aims at characterizing the chemical indices of extracted essential oils and evaluating the antibacterial activity of each essential oil by titration and disc diffusion method respectively. On the other hand, it attempts at evaluating the combined action of essential oils against four reference pathogenic bacterial strains, namely Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Enterococcus faecalis by well and Chabbert-type diffusion method. The essential oils obtained by the hydrodistillation method have a relatively average extraction about 1.43, 2.3 and 2.5%, respectively for caraway, cumin, and cinnamon. The acid index indicates the behavior and amount of free acids present in the essential oil, in which the acid and saponification indices of cinnamon essential oil indicate a value of 4.48 and 168.56 respectively. It can also inform us about the susceptibility of the oil to undergo alterations. The antibacterial activity results showed that cinnamon essential oil (EO) proved to be the most active against the tested bacterial strains; caraway EO was active against Enterococcus faecalis, and the antibacterial action of cumin EO was the lowest. However, the association of the extracted essential oils has a higher synergistic effect than the independent effect of each essential oil, in which the MIC value found was estimated at 10 to 20 (V/V), 40 to 50 (V/V) and 50 to 70 (V/V) respectively for cinnamon, cumin and caraway. The obtained results show that the response to the antibacterial activity varies according to the plant species used and the extract tested alone or in combination.

Beef is rich in amino acids and vitamin B6, carnitine, potassium, protein, and other nutrients. It can improve the body’s ability to resist disease and is especially suitable for growth, development, and postoperation and postrehabilitation care. Under such circumstances, the demand for beef consumption in various countries continues to grow steadily. At present, domestic beef prices continue to rise, and beef supply is insufficient. In addition, fresh beef is easy to be infected with microorganisms in the process of cold storage, which makes fresh beef deteriorated. Therefore, it is very important to add preservatives to prolong the shelf life of chilled beef. In this paper, the preservation of chilled beef with nanocapsules made of natural essential oil from plant extracts was studied. In this study, cumin, Zanthoxylum, ginger, cinnamon, clove, and thyme were selected to study the effect of six kinds of essential oils on beef preservation through comparative experiments. On the basis of such research data, the six kinds of essential oils were compounded, respectively, and different nanoessential oil capsules were applied to the fresh-keeping of chilled beef to make different kinds of nanoessential oil capsules. Through the experiment, the compound essential oil with better preservation effect was obtained. And through the comparison, cinnamon essential oil has obvious antibacterial activity, while ginger essential oil has the worst antibacterial effect. The pH value of beef can be changed and the degradation rate of protein in beef will be slowed down by applying appropriate amount of decomposed plant essential oil to beef samples. Through the above experimental results, we applied the compound essential oil to the preservation of cold and fresh beef at nanometer level and found that the effect was significant, which was worthy of application in major beef products processing plants.

Cob regarded as a waste product, constituting source of environmental pollution could be utilized as an energy source in feed formulation if properly processed and harnessed through fungal degradation. Hence, this study was designed to evaluate the nutritive value of biodegraded corncob meal based diet using in vitro gas production technique. Aspergillus niger was isolated and sub-cultured to obtain a pure culture. Degraded corn cob meals(DCCM) of four dietary treatments were prepared to include: T (0% DCCM which served as 1 the control), T (15% DCCM), T (30% DCCM) and T (45% DCCM). Each diet sample 2 3 4 (200mg) was incubated in buffered rumen liquor for 48 hours and gas volume was estimated using established in vitro gas production models. Amount of gas volume produced was determined every 3 hours for 48 hours of incubation in buffered rumen fluid. After 48 hours ofincubation, methane gas produced was estimated and determined in triplicates. The proximate composition of Aspergillus niger biodegraded corn cob indicated that Aspergillus niger improved the nutritive value of the corn cob. Untreated corn cob meal was lower in nutritive values when compared with treated corncob meal with crude protein, crude fibre and ash values ranging from 6.88 to 9.78%, 32.68 to 26.37% and 2.87 to 2.88% respectively.The proximate composition of the dietary treatments showed that the crude protein varied from (11.67-12.67%), crude fibre (10.94-21.56%), ether extract (2.12-4.88%), ash (6.48- 9.44%) and nitrogen free extract (58.17-62.99%). Results obtained for volume of gas (35.960-72.770mL/200mgDM) produced in time “t” denoted by (b) were significantly different (P<0.05) across the dietary treatments. However, rate of gas production (0.0297- 0.0425mL/hr) and time between incubation and gas production (2.083-2.683hr) were not significantly different (P>0.05) across the dietary treatments. Cumulative gas volumeproduction at 24 hours were significantly (P<0.05) influenced by different inclusion levels of DCCM with values obtained ranging from T (15.33 ml/gDM) to T (35.33 ml/gDM). There 4 3 were significant differences (P<0.05) across the dietary treatments. The post estimated parameters ranging from metabolisable energy (4.96-7.74MJ/Kg DM), organic matter digestibility (37.98-58.03%), short chain fatty acids (0.31-0.78μmol), Methane estimate (3-8  ml/200mgDM) and Carbon dioxide estimate (10-30 ml/200mgDM). It can be concluded that 30% DCCM based diet had the potential of meeting the nutritional needs as smallruminant livestock feeds, if properly biodegraded and incorporated into feeds.

Essential oils are known to be susceptible to changes and degradation that can lead to loss of quality and pharmacological properties. In this work, lemongrass essential oil is stored under different storage conditions under the influence of light and temperature, assessing the physical and chemical properties as well as the chemical composition of the citronella essential oil respectively. The change in the chemical composition of citronella oil is determined based on the storage time of 4 months under different conditions i.e. light (45 ºC) and in dark (4 ºC). To determine the change in the composition of the essential oil, based on the results of GC-MS analysis methods to monitor the chemical changes of the essential oil. The content of main components of citral and β-myrcene increases significantly after storage time under the influence of light and temperature. Some low content components (β-citronello, β-caryophyllen, p-cymen-8-ol, etc.) are likely to be oxidized and lost under light conditions, even in the dark. Therefore, the importance of external storage factors for the chemical and physical stability of essential oils is a matter of concern to control the quality of scientific evaluation.

Abstract: The objective of this work was to evaluate the effects of urea ammoniation of pearl millet silage, at different compaction densities, on chemical composition, losses in the ensilage process, fermentation profile, microbial population count, and aerobic stability. The experimental design was completely randomized, in a 2×4 factorial arrangement, with two compaction densities (600 and 800 kg m-3) and four urea levels (0, 2, 4, and 6% on a dry matter basis), with five replicates. For the aerobic stability assay, the experimental design was completely randomized, in a 2×4 factorial arrangement, with two times (0 and 72 hours) and four urea levels (0, 2, 4, and 6%, on dry matter basis), with five replicates. The urea levels interacted significantly with density as to the contents of organic matter, crude protein, neutral detergent insoluble protein, and as to dry matter recovery; and with exposure hours as to the contents of acid detergent fiber and lignin. Molds and yeasts were not observed in the ammoniated silages. The 800 kg m-3 density reduced losses in the fermentation process of pearl millet silage, and promoted better nutritive value than the compaction at 600 kg m-3. The use of urea does not reduce losses and does not improve the aerobic stability of silages; however, it controls mold growth after silage exposure to air.

The objectives of this study were to evaluate the antimicrobial efficacy of cinnamon essential oil (CEO) and rosemary essential oil (REO) against 4 food-related microorganisms. The chemical components of CEO and REO were also analyzed by GC/MS. The major active constituents of CEO were cinnamaldehyde (80.010%) and 2-methoxycinnamaldehyde (10.550%), and the major active constituents of REO were 1,8-Cineole (51.783%) and α-Pinene (13.508%).The antimicrobial results indicated that both them display strong inhibition against 4 strains. The combination showed additive efficacy against all tested microorganisms. Thus, our study demonstrated that CEO and REO can be considered potential alternatives to control pathogens and microbial in the food or food packaging material.
