Problems solved by technology

[0003] In 2010 and 2011, during the cultivation of Penaeus vannamei across the country, there were cases of stealthy deaths caused by enteritis, and the incidence rate in the whole country exceeded 50%, especially the cultivation area of ​​Penaeus vannamei accounted for 60-70% of the national cultivation area. In South China, more than 80% of the cases of enteritis in the breeding process lead to stealing deaths, which caused great economic losses to farmers.

Example Embodiment

[0015] Example 1 Preparation of additives

[0016] To prepare 1 kg of additives, the raw materials used: 5 g of gentian, 5 g of cork, 5 g of tangerine peel, 5 g of magnolia bark, 4 g of rhubarb, 6 g of tuckahoe, 4 g of scutellaria, and 6 g of astragalus, plus 60 g of corncob powder, mixed and crushed, and then sieved.

Example Embodiment

[0017] Example 2

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

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

[0020] Using the comparison test between this example and the control group, through the experiment of 20 breeding ponds, compared with the Penaeus vannamei fed the control group feed, the seed survival rate increased by 5-10%, and the breeding success rate increased by 10-15%. The cycle is shortened by 5-7 days, and the shrimp size is similar;

[0021] The weight percentage of the air-dried feed of the control group includes the following components: 28%...

[0022] Example 3

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

[0024] This example contains 41.14% crude protein, 7.78% crude fat, 2.52% lysine, and 0.73% methionine, and the composition ratio is reasonable;

[0025] In Jiangmen, Guangdong, the 20 farmers who used the formula feed of this example had a 10-15% reduction in the incidence of enteritis, an increase in the breeding success rate by 10-15%, and a shortened breeding cycle compared with those fed with other common feeds of Penaeus vannamei. Within 5-7 days, the breeding efficiency will be greatly improved;

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. ...
