Problems solved by technology

At present, the animals that use purple elephant grass as feed are all herbivores, and most of them are fed directly with fresh purple elephant grass, because the growth time of purple elephant grass is only a few months, and the use of fresh feeding severely limits the feeding of purple elephant grass. time, and feed fresh purple elephant grass directly. This method has the problem of long digestion time after feeding. It is necessary to strictly control the feeding time to prevent animals from being starved if they are not supplied in time.
At this stage, forage is also used after silage, but there are several problems with silage. The storage requirements of silage are high, and it is necessary to avoid damp and moldy and produce aflatoxin. Feeding animals containing aflatoxin is not only harmful to the growth of animals, but also easy to cause Animals get sick or die, and if people eat the meat, eggs or milk of these animals, it is easy to cause human poisoning or cancer. Therefore, it is urgent to find a new feed for purple elephant grass

Embodiment 1

[0029] A kind of purple elephant grass feed, according to the percentage by weight, the feed ratio is shown in Table 1, 2, 3,

[0030] The astragalus extract of this example is prepared by the following method: after taking out the stems of fresh astragalus and performing ultra-microwave pulverization, adding 2 times the volume of pure water, refluxing and extracting at 70°C for 3 times, combining 3 times of reflux and filtering Filtrate, then the combined filtrate is concentrated in a water bath and microwave-assisted to concentrate to 1.10 times the original volume. Extraction for 30S, followed by vacuum drying to obtain Astragalus extract. The content of astragalus polysaccharide in it reaches 98%.

[0031] The ginkgo leaf extract of this example is prepared by the following method: dry the fresh ginkgo leaves at 40°C, then crush them, add 2 times the volume of pure water to soak for 5 minutes, and then heat them in a water bath to 38°C After adding cellulose degrading en...

[0041] A kind of purple elephant grass feed, according to the percentage by weight, the feed ratio is shown in Table 1, 2, 3,

[0042] The astragalus extract of this example is prepared by the following method: after taking out the stems of fresh astragalus and performing ultra-microwave pulverization, adding 2 times the volume of pure water, refluxing and extracting at 70°C for 3 times, combining 3 times of reflux and filtering Filtrate, then the combined filtrate is concentrated in a water bath and microwave-assisted to concentrate to 1.10 times the original volume. Extraction of 40S, followed by vacuum drying to obtain Astragalus extract. Wherein the content of astragalus polysaccharides reaches 99%.

[0043] The ginkgo leaf extract of this example is prepared by the following method: dry the fresh ginkgo leaves at 40°C, then crush them, add 2 times the volume of pure water to soak for 5 minutes, and then heat them in a water bath to 38°C Add cellulose degrading enzymes t...

Embodiment 3

[0053] A kind of purple elephant grass feed, according to the percentage by weight, the feed ratio is shown in Table 1, 2, 3,

[0054] The astragalus extract of this example is prepared by the following method: after taking out the stems of fresh astragalus and performing ultra-microwave pulverization, adding 2 times the volume of pure water, refluxing and extracting at 70°C for 3 times, combining 3 times of reflux and filtering Filtrate, then the combined filtrate is concentrated in a water bath and microwave-assisted to concentrate to 1.10 times the original volume. 32S was extracted, followed by vacuum drying to obtain Astragalus extract. Wherein the content of astragalus polysaccharides reaches 98.5%.

[0055] The ginkgo leaf extract of this example is prepared by the following method: dry the fresh ginkgo leaves at 40°C, then crush them, add 2 times the volume of pure water to soak for 5 minutes, and then heat them in a water bath to 38°C After adding cellulose degradin...

Abstract

The invention discloses a pennisetum purpureum Schumab cv.Purple feed and a preparation method and application thereof. The pennisetum purpureum Schumab cv.Purple feed is prepared from the following raw materials in percentage by weight of 55%-70% of pennisetum purpureum Schumab cv.Purple, 20%-30% of fermentation additives and 10%-15% of mixed microorganisms through anaerobic fermentation, whereinthe fermentation additives comprise astragalus extracts, ginkgo leaf extracts, Chinese magnoliavine fruit extracts, soyabean bran, 5%-10% calcium chloride, manganese sulfate, and ferrous disulfide; and the mixed microorganisms comprise cellulose decomposing bacteria, flavobacterium, bacillus subtilis and lactobacilli. The pennisetum purpureum Schumab cv.Purple feed disclosed by the invention hasthe advantages that the obtained pennisetum purpureum Schumab cv.Purple feed has acid flavor, and the storing condition is not high; and according to the pennisetum purpureum Schumab cv.Purple feed disclosed by the invention, the palatability of the feed is improved, the appetite of animals is stimulated, and the food consumption is increased.

Description

【Technical field】 [0001] The invention belongs to the technical field of feed preparation, and in particular relates to a purple elephant grass feed and a preparation method and application thereof. 【Background technique】 [0002] Purple elephant grass (Pennisetum purpureum Schumab cv.Purple) is native to Brazil. It has tall plants, well-developed root system, purple stems and leaves, asexual reproduction, cold resistance, strong stress resistance, many tillers, high yield, and the fiber contained in purple elephant grass. The protein (cellulose, hemicellulose, lignin) is higher, the crude protein content is also higher, and the amino acid weight content accounts for 7-8% of the nutritional labeling. At present, the animals that use purple elephant grass as feed are all herbivores, and most of them are fed directly with fresh purple elephant grass, because the growth time of purple elephant grass is only a few months, and the use of fresh feeding severely limits the feeding ...
