Problems solved by technology

Under normal circumstances, the diarrhea rate of 3-5 days after weaning is 0.6%; and 8-13 days, the diarrhea becomes severe, and the diarrhea rate reaches about 32%. The mortality rate caused by the disease can reach 10-20%. , its growth and development will also be seriously affected, delaying the slaughter time and bringing huge economic losses to farmers
[0003] Longan shell is a common fruit shell in life, which contains a lot of ingredients that are beneficial to animals and humans. It is reported that longan shell contains a lot of alkaloids and other traditional Chinese medicine ingredients. my country's longan production ranks first in the world. A large number of shells are discarded as waste, resulting in a great waste of resources
[0004] The current feed additives do not have a specific and effective feed additive to combat this piglet diarrhea, most of them are treated with drugs. Some Chinese herbal medicines have been used as feed additives in China, but no active ingredients added to processed longan shells have been seen. Feed Additives

Embodiment 1

[0022] The preparation method of the feed additive mainly preventing and treating piglet diarrhea comprises the following steps:

[0023] Take the longan shell and dry it, weigh 200g of the longan shell, and crush it in a tissue grinder to obtain the longan shell crushed material; add 1000ml of purified water to the crushed material, and then add 4000U of cellulase for enzymatic hydrolysis. The hydrolysis time was 180min, and the enzymolysis temperature was 55°C; the enzymolysis liquid after enzymolysis was extracted at 100°C, so that the active ingredients were dissolved in hot water, and the extraction time was 3 hours; The liquid is centrifuged, the rotating speed of the centrifuge is 4000r / min, the centrifugation time is 10min, and the upper layer liquid is collected after centrifugation;

[0024] Weigh 20g of glucose, 5g of sodium chloride, 20g of Divine Comedy powder, 30g of licorice, 20g of baldhead grass, 60g of herb, 50g of carrot, and 50g of rice flour. Add the above...

Embodiment 2

[0027] The preparation method of the feed additive mainly preventing and treating piglet diarrhea comprises the following steps:

[0028] Take the longan shells and dry them, weigh 200g of the longan shells, and crush them in a tissue grinder to obtain ground longan shells; add 1500ml of purified water to the ground longan shells, and then add 5000U of cellulase for enzymolysis. The hydrolysis time was 120min, and the enzymolysis temperature was 55°C; the enzymolysis solution after enzymolysis was extracted at 100°C, so that the active ingredients were dissolved in hot water, and the extraction time was 4 hours; Liquid was subjected to centrifugation, the rotating speed of the centrifuge was 3500r / min, and the centrifugation time was 12min. After centrifugation, the upper layer liquid was collected and concentrated to 1L by a rotary evaporator; 50g licorice, 30g baldhead, 60g herb, 80g carrot, 70g rice flour, add the above ingredients to the upper liquid after centrifugation; ...

Abstract

The invention discloses a preparation method of a feed additive mainly used for preventing and treating piglet diarrhea and the feed additive prepared by using the preparation method, and belongs to the field of feed processing. The preparation method mainly comprises the steps of firstly processing longan shells, carrying out enzymolysis, leaching and centrifuging to obtain supernatant liquid, adding glucose, sodium chloride, medicated leaven, licorice, Chinese bulbul, rhizoma atractylodis, carrots and rice flour into the collected supernatant liquid, and carrying out blending, filling, sterilizing, cooling and warehousing. The preparation method is scientific and reasonable. According to the feed additive prepared by adopting the preparation method, intestinal floras can be effectively adjusted, the growth of pathogenic microorganisms is inhibited, the normal intestinal microflora is beneficially maintained, the diarrhea rate of weaned piglets can be reduced, and the healthy growth of the piglets can be promoted; by adequately utilizing effective constituents in the longan shells, the resource wasting of the longan shells is avoided.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to a preparation method of a liquid feed additive mainly for preventing and treating piglet diarrhea and the feed additive. Background technique [0002] Diarrhea in weaned piglets is quite common in pig production. According to the survey, the diarrhea rate of weaned piglets is around 20% to 30%. Under normal circumstances, the diarrhea rate of 3-5 days after weaning is 0.6%; and 8-13 days, the diarrhea becomes severe, and the diarrhea rate reaches about 32%. The mortality rate caused by the disease can reach 10-20%. , its growth and development will also be seriously affected, delaying the slaughter time and bringing huge economic losses to the farmers. [0003] Longan shell is a common fruit shell in life, which contains a lot of ingredients that are beneficial to animals and humans. It is reported that longan shell contains a lot of alkaloids and other traditional Chinese medici...
