Method used

In summary, it can be illustrated by experiments of the present invention that cinnamaldehyde and eugenol are made into slow-release agents to replace rumenin to play a role in the rumen, promote the proliferation of rumen microorganisms in the rumen, and improve the volatility of the rumen in the rumen Fatty acid content can increase propionic acid production, reduce the ratio of acetic acid/propionic acid, and improve rumen function.

In the above-mentioned steps, the specific method that carvacrol and thymol are used to pass through the rumen with the carrier to do rumen coating comprises the following steps: the carrier with the rumen is heated to 90 ℃ of melting, add carvacrol and thyme in proportioning Phenol, mix well, then spray dry and cool. Heating the rumen-passing carrier to 90...

Abstract

The invention provides a plant essential oil composition for dairy cows and a preparation method thereof. The plant essential oil composition comprises, by weight, 1-8 parts of eugenol subjected controlled-release treatment, 1-15 parts of cinnamyl aldehyde and a mixture of carvacrol and thymol which are subjected to rumen bypass treatment, wherein the mixture comprises 1-8 parts of carvacrol, 1-8 parts of thymol and 10-40 parts of carriers for rumen bypass. The preparation method includes: using the carriers for rumen bypass as the rumen bypass coating of the carvacrol and the thymol to obtain a product, and evenly mixing the obtained product with the eugenol and the cinnamyl aldehyde to obtain the plant essential oil composition. The plant essential oil composition is mainly used for replacing rumensin in the rumen, inhibiting and killing harmful bacteria in the intestinal tracts of the dairy cows, promoting the proliferation of beneficial bacteria, preventing the diarrhea and constipation of the dairy cows, lowering somatic cell counts and increasing milk yield, milk fat rate and milk protein rate.

Example Embodiment

[0066] Example 1

[0067] In this example, the preparation of a plant essential oil composition for dairy cows with a total plant essential oil content of 10% includes the following steps:

[0068] 1) Weigh 30 g of eugenol, 40 g of cinnamaldehyde, 10 g of carvacrol, and 20 g of thymol for use.

[0069] 2) Weigh 8g of methylcellulose and 17g of xanthan gum, dissolve them in 295ml of distilled water, add eugenol and cinnamaldehyde, mix well, then add 180g of white carbon black, mix, and use white carbon black for adsorption , Get the first mixture.

[0070] 3) Weigh 400g of saturated fatty acids (in the saturated fatty acids, the content of C16-C18 saturated fatty acids is 72%, and the melting point of saturated fatty acids is 52°C), heat to 90°C to melt, add carvacrol and thymol to the molten product And mix, and spray the mixed product into the cooling tower through the nozzle of the centrifugal spray dryer to obtain the second mixture.

[0071] 4) Mix the first mixture and the second mixture uniformly to obtain a plant essential oil composition for dairy cows with a plant essential oil content of 10%.

Example Embodiment

[0072] Example 2

[0073] In this example, preparing a plant essential oil composition for dairy cows with a total plant essential oil content of 20% includes the following steps:

[0074] 1) Weigh 80 g of eugenol, 70 g of cinnamaldehyde, 30 g of carvacrol, and 20 g of thymol for use.

[0075] 2) Weigh 10g of methyl cellulose and 20g of xanthan gum, dissolve them in 200ml of distilled water, add eugenol and cinnamaldehyde, mix well, then add 400g of white carbon black, mix evenly, use white carbon black Adsorption to obtain the first mixture.

[0076] 3) Weigh 170g of saturated fatty acids (in the saturated fatty acids, the content of C16-C18 saturated fatty acids is 72%, and the melting point of saturated fatty acids is 52°C), heat to 90°C to melt, and add carvacrol and thyme to the molten product Phenol is mixed evenly, and the mixed product is sprayed into the cooling tower through the nozzle of the centrifugal spray dryer to obtain the second mixture.

[0077] 4) Mix the first mixture and the second mixture evenly to obtain a plant essential oil composition for dairy cows with a plant essential oil content of 20%.

Example Embodiment

[0078] Example 3

[0079] In this example, preparing a plant essential oil composition for dairy cows with a total plant essential oil content of 25% includes the following steps:

[0080] 1) Weigh 50 g of eugenol, 100 g of cinnamaldehyde, 50 g of carvacrol, and 50 g of thymol for use.

[0081] 2) Weigh 10g of methylcellulose and 20g of xanthan gum, dissolve them in 350ml of distilled water, add eugenol and cinnamaldehyde, mix well, then add 200g of white carbon black, mix, and use white carbon black for adsorption , Get the first mixture.

[0082] 3) Weigh 170g of saturated fatty acids (in the saturated fatty acids, the content of C16-C18 saturated fatty acids is 72%, and the melting point of saturated fatty acids is 52°C), heat to 90°C to melt, and add carvacrol and thymol to the molten product And mix well, and spray the mixed product into the cooling tower through the nozzle of the centrifugal spray dryer to obtain the second mixture.

[0083] 4) Mix the first mixture and the second mixture evenly to obtain a plant essential oil composition for dairy cows with a plant essential oil content of 25%.
