Description

A kind of milk cow plant essential oil composition and preparation method thereof
Technical field
The invention belongs to field of feed additive technology more particularly to a kind of milk cow plant essential oil composition and its preparations Method.
Background technology
The use of antibiotic ionophore (Rumensin) can reduce energy caused by lumen fermentation and protein Loss.However, drug-fast bacteria may be remained and generate in livestock products without by big well-established by adding antibiotic in feed. In January, 2006, European Union has prohibited the use of antibiotic.China cannot clearly add antibiotic in milk cow forage. Based on this, the begin one's study substitute of antibiotic of animal nutrition science man regulates and controls lumen fermentation, including yeast, organic Acid, plant extracts (mainly plants essential oil) and probiotic.
Plants essential oil has extensive antibacterial activity, has inhibitory or killing effect for Gram-negative bacteria and positive bacteria.These What substance had can promote lumen fermentation, some inhibition lumen fermentations, some inhibition methane to generate, and what is had can change volatility The composition and nitrogen metabolism of aliphatic acid.Some are the study found that certain plants essential oil and its group branch change each volatile fatty acid Ratio, effect is similar with coban (for example reducing proportion of acetic acid, increase propionic acid ratio), these are considered as addition plant essence The Beneficial Effect of oil.
Thymol (C10H14O), it is also Thymol, is the isomer of carvacrol, to most of Gram-positives Bacterium and Gram-negative bacteria have inhibiting effect, are the active constituents for studying a kind of more plants essential oil at present.Borchers (1965) influence of the thymol to lumen fermentation is had studied in vitro method, adding the thymol of 1000mg/L reduces culture The concentration of ammonia nitrogen improves the concentration of amino acid nitrogen, illustrates that it can inhibit deamination.Evans etc. (2000) reports, Under the conditions of pure culture, thymol has an impact bargen's streptococcus and the energetic supersession for ruminating the crescent monad of beast.It can be dropped The concentration of low methane and lactic acid, but the production of nutritive digestibility and general volatile aliphatic acid can be reduced by improving additive capacity Amount.Addition 100-400mg/L thymols make the ratio of acetic acid and propionic acid increase.Sensitivity of the crescent monad to thymol Property by force than bargen's streptococcus (main Lactic Acid Producing), so as to cause the accumulation of lactic acid in rumen fluid, causes rumen fluid ph to drop It is low, it has a negative impact to lumen fermentation.And the purpose of regulating rumen is exactly the opposite, it should try hard to reduce the concentration of lactic acid.It answers The growth of the stimulation meniscus monad, inhibits the growth of bargen's streptococcus.It is slow that cud can be added while adding thymol Electuary (NaHCO3 etc.).Castillejos etc. (2006) in vitro study shows that the thymol of 50mg/L does not have lumen fermentation It influences, but the dosage of 500mg/L reduces the concentration of general volatile aliphatic acid and ammoniacal nitrogen;Long-term continuous cultivation and fermentation system Result of study shows that the optimal dose of thymol is 50-500mg/L.In addition, the effect of thymol is by daily ration and cud The influence of pH value.In daily ration essence slightly than being 40: 60 (coarse fodder is alfalfa), under conditions of pH is 6.4, thymol improves The ratio of acetic acid and propionic acid.In daily ration essence slightly than being 90: 10 (coarse fodder is stalk, and fine fodder is corn, barley and dregs of beans), pH is Under the conditions of 5.5, thymol reduces the ratio of acetic acid and propionic acid.
Eugenol (C10H12O2) have extensive antibacterial activity, be cloves, cassia oil main active.Continuous culture Fermentation system reduces the molar ratio of acetic acid and branched chain fatty acid studies have shown that adding 2.2mg/L, improves mole of propionic acid Ratio.Eugenol can also influence the metabolism of nitrogen, improve the concentration of peptide and reduce the concentration of amino acid nitrogen, illustrate that it can be reduced The activity of rumen fluid peptase.Busquet etc. (2006) is studies have shown that eugenol can regulate and control the fermentation of cud, the total volatilization of reduction Property aliphatic acid and ammoniacal nitrogen concentration, the linear molar ratio for improving propionic acid, the influence to acetic acid and butyric acid is in quadratic effect.One As for, suitable dosage can improve dietary digestibility of energy and the utilization ratio of nitrogen.There is data to suggest that in daily ration essence slightly than being 40 : under conditions of 60 (fine fodder is corn, barley and dregs of beans, and coarse fodder is alfalfa), eugenol reduces branched chain fatty acid and tumor The concentration of gastric juice ammoniacal nitrogen, deamination are inhibited.Daily ration essence slightly than for 90: 10 (coarse fodder is stalk, fine fodder be corn, Dregs of beans and barley) under the conditions of, eugenol reduces the concentration of general volatile aliphatic acid and the ratio of propionic acid, improves the ratio of acetic acid The ratio of example and acetic acid/propionic acid.This fermentation pattern is unfavorable to beef cattle production, and is advantageous to lactating cow.
Cinnamic acid (C9H8O) has antibacterial activity, is the main active of cassia oil, accounts for 75% of extract or so. Cardozo etc. (2005) reports that experiment uses dosage for the continuous culture system of 0.22mg/L rumen fluids, the results showed that, it is right Nitrogen metabolism has regulating and controlling effect, inhibits the activity of peptase, but to volatile fatty acid almost without effect.Cassia oil and cinnamic acid Additive capacity, which is 3000mg/L rumen fluids, reduces general volatile aliphatic acid and ammonia nitrogen concentration.To single volatile fatty acid ratio Influence it is different, cassia oil improves the molar ratio of acetic acid, but is not influenced on the molar ratio of propionic acid and butyric acid, Cinnamic acid improves the ratio of propionic acid, is not influenced on acetic acid and butyric acid.These results indicate that cinnamic acid is the main of cassia oil Active constituent, the other compositions in cassia oil have interaction, the effect of cinnamic acid more ideal with cinnamic acid.Busquet etc. (2005) every liter of rumen fluid is had studied using Dual-flow continuous culture fermentation system and adds 31.2,312mg cinnamic acids respectively to tumor The influence of stomach fermentation.The result shows which reduce the molar ratio of acetic acid, the molar ratio of propionic acid and butyric acid is improved.Ferme It is reported Deng (2004), cinnamic acid can reduce the quantity of melaninogenicus, and this bacterium has the function of deamination.Above experiment knot Fruit and discussion are obtained based on milk cow under conditions of high coarse fodder daily ration.Cardozo etc. (2005) uses smart slightly ratio for 90: 10 The rumen fluid of beef cattle under the conditions of daily ration, the in vitro study effect of cassia oil and cinnamic acid.When pH is 7, can both improve The ratio of acetic acid and propionic acid reduces the concentration of ammonia nitrogen, shows that nutrient utilization ratio reduces.Comparatively, when pH is 5.5, Ammonia nitrogen concentration and the third ratio of second all reduce.
(2011) such as domestic scholars woods waves have studied cinnamon oil, origanum oil and its main component cinnamic acid, perfume (or spice) in vitro method 0,50,200,500 and 750mg/L, hair are added in the influence that celery phenol ferments to vitro Rumen and methane generates in zymotic fluid respectively Existing general volatile fatty acid concentration is reduced with the increase of plants essential oil additive amount, and high dose (500,750mg/L) addition When, entire fermentation process is significantly inhibited.
In conclusion addition cinnamic acid and eugenol have positive acting to function of rumen of cow, you can to improve in cud Propionic acid yield reduces acetic acid/propionic acid ratio.And add thymol has negative role to function of rumen of cow, that is, reduces propionic acid production Amount improves acetic acid/propionic acid ratio.
Han Xu (2013) on laying hen studies have shown that addition origanum oil after can reduce enteron aisle Escherichia coli, Salmonella The quantity of bacterium improves enteron aisle lactic acid bacteria and bifidobacteria, improves the height of intestinal villi, reduce the depth of crypts, improves The activity of enteron aisle amylase, trypsase and lipase, increases glucose transporters (SGLT1, GLUT2) and small peptide transhipment carries The mrna expression amount of body (PePT1), and then improve laying hen enteron aisle digestion and absorption function, improve the quantity of small bowel lymphatics cell.Hao Dan Dan (2014), further studies have shown that can improve the amount of CD4+ in spleen after addition origanum oil, reduces CD8+ on laying hen Amount, improve CD4+/CD8+ ratios, the amount of IgG, IgA, IgM in chicken serum can be improved.The expression quantity of IL-2mRNA in spleen It is significantly improved with the expression quantity of IL-4mRNA.Show that the immunity of body significantly enhances.
