Embodiment 1

[0019] Example 1: Effects of sodium butyrate on eel growth and blood biochemical indicators

[0020] Experimental material: microcapsule sodium butyrate (effective content is usually 30%), commercially available, for example, can be purchased from Hangzhou Kangdequan Feed Co., Ltd.

[0021] Referring to the eel commercial feed formula, two basic feeds with different fish meal content were prepared, high fish meal basic feed (42% fish meal) and low fish meal basic feed (32% fish meal). Add 1000 mg / kg microcapsule sodium butyrate, and prepare 4 kinds of experimental feeds with equal nitrogen and equal energy.

[0022] The rice field eels used in the experiment were wild rice field eels with neat specifications. They were domesticated and cultured in cages in a rice field eel farm in Xihu District, Changde City. No bait was fed to the eels within 2 days after entering the cages. First, a small amount of earthworms and Fresh fish paste, according to the feeding situation, gradu...

Embodiment 2

[0032] Example 2: The effect of sodium butyrate on the intestinal morphology and absorption function of rice field eel

[0033] The experimental feed formula, experimental fish grouping and feeding methods were the same as in Example 1.

[0034] The experimental results are shown in Figure 1, Table 4 and Table 5.

[0039]

[0040] Depend on figure 1 It can be seen that the villi in group A are relatively thin, the intestinal epithelium occasionally falls off at the top of the intestinal villi, and the structure of the mucosa is incomplete; the villi in group B are thick and arranged neatly, the structure of the striation border on the surface of the mucosa is clear, the shape of the intestinal mucosal epithelial cells is regular, and the arrangement is tight. Brightly stained. However, there was...

Abstract

The invention discloses application of sodium butyrate to a feed for rice field eels, and a feed for the rice field eels. The content of fish meal in the feed is smaller than 35 percent, the content of plant protein sources in the feed is greater than 40 percent, sodium butyrate is added to the feed, and 0.5-1g of micro-capsule sodium butyrate is added to each kilogram of feed. According to the feed, sodium butyrate is added to the feed for the rice field eels in a manner of a feed additive, mainly aiming at the problems of high price of the fish meal, high formula cost, and structural damage of an intestinal tract form and reduced immunity and growth caused by reduced content of the fish meal in an aquatic feed formula and consumption of a large quantity of plant protein sources, the intestinal tract form of the rice field eels is effectively restored, the absorbing capacity of the intestinal track and the immunity of an organism are enhanced, the growth of the rice field eels is promoted, the feed utilization rate is increased, the application of the plant protein sources in an aquatic feed is improved, the feed cost is lowered; meanwhile, the feed is simple in adding manner, low in cost and remarkable in benefit.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive which can effectively restore the intestinal morphology of eel and improve intestinal absorption function, immunity and growth of eel when added to low-fishmeal feed, and belongs to the technical field of aquatic feed . Background technique [0002] Fish meal has high protein content, amino acid balance, good palatability, and less anti-nutritional factors. It is the most widely used protein source in aquaculture feed. Demand exceeds supply, therefore, seeking high-quality protein sources to replace fishmeal has become a research hotspot. Plant protein sources (such as soybean meal) are considered to be the best choice to replace fishmeal due to their low price, wide sources, balanced amino acids and high protein content, and are widely used in aquatic feed. Nutritional factors, such as soybean saponins, these anti-nutritional factors will destroy the intestinal morphology and...
