Embodiment 1

[0064] A premix for preventing stress enteritis of sea bass, which is prepared from the following components in parts by weight: 8 parts of guava leaf fermentation liquid, 28 parts of fermented liquid of Michelia chinensis, 12 parts of fermented liquid of pearl vegetable, compound mineral 0.3 parts, 55 parts of soybean meal.

[0065] Wherein, the guava leaf fermentation liquid is prepared by a method comprising the following steps: mixing guava leaves: water: photosynthetic bacteria liquid medium and photosynthetic bacteria, and cultivating in a closed light transmission at 30-37°C until the OD value is 3-4.5 Obtain the culture, continue to fully illuminate until the end of the culture period during the culture, the culture is centrifuged, and the supernatant collected is the guava leaf fermentation liquid; Wherein, the guava leaf: water: the weight-to-volume ratio of the photosynthetic bacteria liquid medium is 1:( 6-12): (2-8), the amount of photosynthetic bacteria added is ...

Embodiment 2

[0071] A premix for preventing stress enteritis of sea bass, which is prepared from the following components in parts by weight: 9 parts of guava leaf fermentation liquid, 30 parts of fermented liquid of fenugreek, 14 parts of fermented liquid of pearl vegetable, compound mineral 0.4 parts, 50 parts of soybean meal.

[0072] Wherein, the guava leaf fermentation liquid is prepared by a method comprising the following steps: mixing guava leaves: water: photosynthetic bacteria liquid medium and photosynthetic bacteria, and cultivating in a closed light transmission at 30-37°C until the OD value is 3-4.5 Obtain the culture, continue to fully illuminate until the end of the culture period during the culture, the culture is centrifuged, and the supernatant collected is the guava leaf fermentation liquid; Wherein, the guava leaf: water: the weight-to-volume ratio of the photosynthetic bacteria liquid medium is 1:( 6-12): (2-8), the amount of photosynthetic bacteria added is 1╳105cfu-...

Abstract

The invention relates to fish feed premix, in particular to premix for preventing sea bass irritable enteritis and a preparation method and application thereof. The premix comprises, by weight, 5-10 parts of guava leaf fermentation broth, 15-35 parts of Euphorbia thymifolia fermentation broth, 10-15 parts of Lysimachia clethroides fermentation broth and 0.1-0.5 part of compound minerals. Compared with existing nutritional premix added into sea bass feed, the premix has the advantages that various active factors are obtained by using the unique fermentation technology, the compound minerals are added to achieve a synergistic effect, and the premix has an evident preventing effect on the sea bass irritable enteritis and can effectively relieve the symptoms of the sea bass irritable enteritis.

Description

technical field [0001] The invention relates to a fish feed premix, in particular to a premix for preventing sea bass irritant enteritis, a preparation method and an application of the premix. Background technique [0002] Sea bass is an important economic species of mariculture. There are mainly two types of culture in earthen ponds and offshore cages in China. The culture is mainly distributed in Zhuhai, Guangdong and coastal areas of Fujian. Due to the objective limitations of seed hatching and breeding water quality, the production of sea bass farming remains stable, and the profit return of farming is also relatively stable. Therefore, technological innovation to stabilize the survival rate of sea bass farming is beneficial to the cultivation of sea bass farming industry in my country synergy. [0003] Practice has found that sea bass are more sensitive to local climate conditions, especially to stress factors such as air pressure and white rain. In production, it is of...
