Embodiment 1

[0035] Example 1 provides an additive for freshwater fish with Huaxiangguo extract. The method for extracting the Huaxiangguo extract includes the following steps:

[0036] Step 1: Weigh 1000g of Huaxiang fruit sequence into a round-bottomed flask, add first-grade water at 80°C according to the material-to-liquid ratio of 1:15, heat in an oil bath at 80°C, extract for 1 hour, repeat the extraction twice, and combine the extracts. Concentrate under reduced pressure at 50°C to a quarter of the original volume.

[0037] Step 2: The concentrated solution is freeze-dried to obtain 510 g of extract, and the tannin content is 71.4%.

[0038] The present embodiment also provides an application of a freshwater fish using an aromatic fruit extract feed additive, which is applied in freshwater fish farming. As a preferred technical solution, the prepared feed additive is added in the feed It is 125g / t.

[0039] The specific application process is as follows:

[0040] Feed configuration: The test...

Embodiment 2

[0047] Example 2 provides a freshwater fish with Huaxiangguo extract additive. The extraction method of the Huaxiangguo extract is the same as that of Example 1.

[0048] The present embodiment also provides an application of a freshwater fish using an aromatic fruit extract feed additive, which is applied in freshwater fish farming. As a preferred technical solution, the prepared feed additive is added in the feed It is 250g / t.

[0049] The specific application process is as follows:

[0050] The test feed was prepared in the same manner as in Example 1, and 250 ppm of Huaxiangguo extract was added to the basic diet.

[0051] The juvenile freshwater fish (Tilapia) with the same specifications were randomly divided into 6 breeding buckets (specification 300L), 30 test fish in each breeding bucket. After 15 days of adaptation, the test fish were fed with the test diet and randomly fed with the compound feed supplemented with Huaxiang fruit extract. There were 6 parallel trials. The f...

Embodiment 3

[0053] Example 3 provides an additive for freshwater fish with Huaxiangguo extract, and the extraction method of the Huaxiangguo extract is the same as in Example 1.

[0054] The present embodiment also provides an application of a freshwater fish using an aromatic fruit extract feed additive, which is applied in freshwater fish farming. As a preferred technical solution, the prepared feed additive is added in the feed It is 500g / t.

[0055] The specific application process is as follows:

[0056] The test feed was prepared in the same manner as in Example 1, and 500 ppm of Huaxiangguo extract was added to the basic compound diet.

[0057] The juvenile freshwater fish (Tilapia) with the same specifications were randomly divided into 6 breeding buckets (specification 300L), 30 test fish in each breeding bucket. After 15 days of adaptation, the test fish were fed with the test diet and randomly fed with the compound feed supplemented with Huaxiang fruit extract. There were 6 parallel t...

Abstract

The invention discloses a feed additive for freshwater fish. The feed additive is prepared by extracting platycarya strobilacea infructescence. The additive is applied to freshwater fish culture according to the addition amount of 100-10000 g/t, so that the growth of freshwater fish can be remarkably promoted, the feed coefficient is reduced, the fatness and the serum superoxide dismutase activityare improved, the content of malondialdehyde and nitric oxide in serum is reduced, and the superoxide anion and glutamic oxalacetic transaminase resisting activity is improved. Not only is productionperformance improved, but also fish meat quality is improved. The feed additive does not contain antibiotics, is healthy and environment-friendly, is low in production cost and has a great application prospect.

Description

Technical field [0001] The present invention belongs to the field of feed production, and more specifically, the present invention relates to a feed additive of sesame fruit extract for freshwater fish and its application. Background technique [0002] my country is a big country in aquaculture and antibiotic production, producing approximately 210,000 tons per year. The long-term application of synthetic feed additives such as antibiotics, hormones and growth promoters in breeding has caused problems such as residues of harmful substances and low animal quality, which has brought serious harm to human health. Since 2006, the European Union has banned all additives in feed. antibiotic. my country is about to ban the addition of antibiotics in feed from 2020. The issue of alternatives to feed antibiotics has become a hot topic of widespread concern in society. Non-antibiotic growth-promoting feed additives include enzymes, probiotics, organic acids and plant feed additives. Esp...
