Chinese herbal medicine feed additive for preventing enteritis of Litopenaeus vannamei

Abstract

The invention discloses a Chinese herbal medicine feed additive for preventing enteritis of Litopenaeus vannamei. The feed additive provided by the invention is prepared by mixing rough gentian, Cortex Phellodendri, dried tangerine peel, rhubarb, Magnolia officinalis, rheum officinale, Poria cocos, the root of large-flowered skullcap and the root of membranous milk vetch, and adding a corn cob powder. The feed additive provided by the invention can be used for preventing enteritis of Litopenaeus vannamei, and has the advantage of enhancing growth rate and immunity of Litopenaeus vannamei, and raising success rate of breeding.

Description

technical field

[0001] The invention relates to the field of feed additives in breeding, in particular to a Chinese herbal medicine feed additive for preventing enteritis of Penaeus vannamei. Background technique

[0002] Penaeus vannamei is native to the waters of the Pacific coast of the Americas, and is mainly distributed from northern Peru to the coast of the Gulf of Mexico, with the most concentrated distribution along the coast of Ecuador. Penaeus vannamei has the advantages of large individual, fast growth, low nutritional requirements, and strong disease resistance. It has a strong adaptability to changes in water environment factors, has low requirements for feed protein content, has a meat yield of over 65%, and survives out of water. With the advantages of long time and other advantages, it is an excellent variety for intensive high-yield farming, and it is also the shrimp species with the highest yield per unit among the three major cultured prawns in the world. ...

Examples

Embodiment 1

[0015] Embodiment 1 additive preparation

[0016] Prepare 1kg of additives, raw materials used: gentian 5g, Phellodendron 5g, Tangerine peel 5g, Magnolia officinalis 5g, Rhubarb 4g, Poria cocos 6g, Scutellaria baicalensis 4g and Astragalus 6g, plus 60g of corn cob powder, mixed and crushed and sieved to make.

Embodiment 2

[0018] A kind of feed for Penaeus vannamei, in terms of air-dried weight percentage, comprising the following components: imported fish meal 28%, peeled soybean meal 21.5%, squid paste 3%, flour 20%, shrimp shell powder 6%, peanut kernel cake 14% , 1% fish oil, 2% phospholipids, 1.5% calcium dihydrogen phosphate, 1% Chinese herbal medicine feed additive, and 2% other additives;

[0019] This example contains 40.84% ​​of crude protein, 7.65% of crude fat, 2.48% of lysine, and 0.70% of methionine, and the composition ratio is reasonable;

[0020] Adopt this embodiment and contrast test of control group, by 20 breeding pond tests, compared with the vannamei of feeding control group feed, seed survival rate improves by 5-10%, and breeding success rate improves by 10-15%. The cycle is shortened by 5-7 days, and the specifications of the shrimp are similar;

[0021] The mass percentage of air-dried matter in the feed of the control group included the following components: 28% impor...

Embodiment 3

[0023] A kind of feed for Penaeus vannamei, in terms of air-dried weight percentage, comprising the following components: 30% imported fish meal, 20.5% peeled soybean meal, 3% squid paste, 20% flour, 6% shrimp shell powder, and 13% peanut kernel cake , 1% fish oil, 2% phospholipids, 1.5% calcium dihydrogen phosphate, 1% Chinese herbal medicine feed additive, and 2% other additives;

[0024] Contain 41.14% of crude protein, 7.78% of crude fat, 2.52% of lysine, 0.73% of methionine in this embodiment, and the composition ratio is reasonable;

[0025] In the Jiangmen area of ​​Guangdong, 20 farmers who adopted the formula feed of this embodiment, compared with Penaeus vannamei fed with other common feeds, the incidence of enteritis decreased by 10-15%, the breeding success rate increased by 10-15%, and the breeding cycle was shortened. 5-7 days, the breeding benefit is greatly improved;
