Problems solved by technology

At the same time, wheat straw has the characteristics of being annual, rich in resources, and low in price. However, the high content of crude fiber in wheat straw limits the digestion of the contents of the cell wall by microorganisms and digestive enzymes in the rumen, resulting in poor palatability and low nutritional value of straw. , cannot be efficiently absorbed and utilized by animals, therefore, it is imperative to develop and utilize straw feed resources to improve their utilization rate and nutritional value

Embodiment 1

[0046]

[0047]

[0048] Add the components of the above-mentioned TMR fermented feed materials 1-5 into the TMR mixer truck, stir and mix evenly, adjust the water content to 45%-55% of the total mass of the feed; pour it into a polyethylene plastic bag, and pump it out with a vacuum pump Air, to reach the required density (500-800kg / m 3 ), the bag is sealed and finished; after 10-50 days of fermentation, it can be fed to back cattle.

[0049] Each group of raw materials in the above-mentioned embodiment is feed grade, and is conventional commercially available product, and information is as follows:

[0050] Wheat straw: Shanghai Dingniu Feed Co., Ltd.

[0051] Silage corn: Shanghai Dingniu Feed Co., Ltd.

[0052] Basic material: Shanghai Dingniu Feed Co., Ltd.

[0053] Molasses: Shanghai Mengxin Animal Husbandry Co., Ltd.

[0054] Lactic acid bacteria: French Laman company

[0055] Calcium formate: Shanghai Luyuan Fine Chemical Co., Ltd.

Embodiment 2

[0057] Using the first fermented feed material in Example 1, add each component in the TMR mixer truck in order to stir and mix evenly, adjust the water to 50% of the total mass of the feed; pour the stirred fermented TMR into a polyethylene plastic bag , use a vacuum pump to pump out the air to reach the required density (500-800kg / m 3 ); it is completed after the bag is sealed. Leave it to ferment for 15 days on open ground.

[0058] Laboratory analysis: Sampling and testing the TMR of wheat straw fermented for 0 days and 15 days. The test indicators are dry matter, crude protein, crude fat, neutral detergent fiber, acid detergent fiber and ash.

[0059] Therefore, the raw data of the detection were statistically analyzed with SPSS17.0. The results showed that the dry matter of the fermented wheat straw fermented TMR feed for 15 days was 0.8% lower than that of the fermented wheat straw fermented TMR feed for 0 day, the crude protein was increased by 0.2%, the crude fat wa...

Embodiment 3

[0061] Use the second fermented feed material in Example 1, add each component in the TMR mixer truck in order to stir and mix evenly, adjust the water to 50% of the total feed mass; pour the stirred fermented TMR into a polyethylene plastic bag , use a vacuum pump to pump out the air to reach the required density (500-800kg / m 3 ); it is completed after the bag is sealed. Leave it to ferment on open ground for 20 days.

[0062] Laboratory analysis: Sampling and testing the TMR of wheat straw fermented for 0 days and 20 days. The test indicators are dry matter, crude protein, crude fat, neutral detergent fiber, acid detergent fiber and ash.

[0063] Therefore, the raw data of the detection were statistically analyzed with SPSS17.0. The results showed that compared with the fermented wheat straw fermented TMR feed for 20 days, the dry matter of the fermented wheat straw fermented TMR feed decreased by 0.9%, the crude protein increased by 0.3%, the crude fat increased significa...

Abstract

The invention relates to totally mixed rations (TMR) fermented feed which serves wheat straw as a raw material and is used for reserve cattle of dairy cattle and preparation method thereof. The TMR fermented feed comprises the following components in part by mass: 400 to 700 parts of wheat straw, 100 to 300 parts of ensiling corn, 100 to 300 parts of basic material, 30 to 80 parts of molasses, 3 to 8 parts of lactic acid bacteria and 1 to 5 parts of mildew preventive. In the preparation method, after being stirred and mixed by a stirrer, the components are subjected bagging and fermenting to prepare the TMR fermented feed for the reserve cattle of dairy cattle. The fermented feed has the advantages of good palatability, high digestive absorption rate of animals and the like, so the daily gain in the reserve cattle is improved, and the disease resistance is enhanced. In the TMR fermented feed, a source of the fermented TMR raw material for the reserve cattle of the dairy cattle is enlarged, the cost of the raw material is reduced, the operation is simple, and the application prospect is excellent.

Description

technical field [0001] The invention belongs to the technical field of TMR fermented feed with crops as raw materials, in particular relates to a TMR fermented feed for dairy cows with wheat straw as raw material and a preparation method thereof. Background technique [0002] The concept of Totally Mixed Rations (Totally Mixed Rations) for dairy cows refers to the full-price nutrition of dairy cows designed according to the nutritional regulation technology and the principle of multi-feed matching according to the nutritional needs and feeding purposes of dairy cows in different growth and lactation stages. Diet formula, according to this formula, the various feeds (roughage, silage, concentrated feed and various special feeds and feed additives) fed to dairy cows every day are evenly mixed together through specific equipment and feed processing technology for dairy cows to collect. food feed processing technology. Total Mixed Ration (TMR) technology for dairy cows ensures ...
