Compound feed for promoting proliferation of intestinal lactic acid bacteria of ctenopharyngodon idella, and preparation method thereof

Abstract

The invention discloses a compound feed for promoting proliferation of intestinal lactic acid bacteria of ctenopharyngodon idella, and a preparation method thereof. A microecological preparation (bacillus coagulans or clostridium butyricum living bacteria preparation) is added into the compound feed special for the ctenopharyngodon idella; preferably, the beneficial microecological preparation cantolerate high temperature and high pressure in the feed processing process; therefore, bacillus coagulans and clostridium butyricum which are preferred by the preparation can be directly added in a secondary mixing stage of feed production; the operability in practice is greatly improved; a direct and effective result can be achieved on prevention and treatment of enteritis of the ctenopharyngodon idella; the obtained technical effect is also the technical effect brought by the bacillus coagulans or clostridium butyricum living bacteria preparation and the technical effect of soybean oil in the previous ctenopharyngodon idella feed; furthermore, the lactic acid bacteria solution protected by the grease is added into the feed in a spraying manner, so that a certain survival rate in vitro can be ensured; the lactic acid bacteria solution can be rapidly proliferated after entering the fish body; and the quantity of the lactic acid bacteria in the fish body is directly increased.

Description

technical field [0001] The invention relates to the technical field of aquatic product feed production, in particular to a compound feed for promoting the proliferation of grass carp intestinal lactic acid bacteria and a preparation method thereof. Background technique [0002] Grass carp (Ctenopharyngodon idella) is a typical herbivorous fish belonging to the order Cyprinidae, Cyprinidae, Yarofish subfamily, and grass carp. Grass carp, as the most aquacultured freshwater fish species in China, is cultivated all over the country. Grass carp enteritis is one of the "three diseases of grass carp". Since the intestine is responsible for the important physiological function of digesting and absorbing nutrients, it is also the largest immune organ in the body. Therefore, enteritis directly destroys the normal physiological structure of the intestine and affects the digestive enzymes. Secretion and glandular secretion, thereby reducing the immune function of the body. [0003] T...

AI Technical Summary

Problems solved by technology

Chinese herbal medicine can also treat grass carp enteritis to a certain extent, but the current application process is not standardized. No consistent and positive conclusion has been obtained in terms of experimental prescriptions or curative effects. damage, and at the same time it is inconvenient to use

2) Splashing disinfectants such as chlorine preparations, iodine preparations, etc. into the breeding environment; but at the same time also killed beneficial bacteria and most algae in the water body, breaking the ecological balance of the water body, causing secondary pollution

This invention is unscientific and unreasonable, mainly because: 1) The lactic acid bacteria and lactobacillus referred to in the invention are not resistant to high temperature, and when the ambient temperature reaches 60°C, the lactic acid bacteria will be killed

2) During conditioning and granulation in the existing aquatic feed production process, the temperature inside the modulator should reach at least 85°C, and the conditioning time should be at least 10s, while the pelleting temperature and time of extruded feed are longer, as can be seen from this invention , the lactic acid bacteria it refers to are uncoated, even if they are coated, it is difficult to withstand such harsh production conditions, and they will be killed during the granulation process, so they will not play a role in the intestinal tract of animals at all

3) If it is not added to the commercial feed, but only mixed and fed directly at the breeding terminal, the added lactic acid bacteria are easily lost into the water environment, and only a small part may enter the fish intestines. Due to the small amount of lactic acid bacteria It also cannot play the role of colonization and proliferation, and it is difficult to play the role of probiotics

It can be seen that the invention is neither practical nor scientific.
