Embodiment 1-5

[0028] On the basis of the basal ration, 5 wt% of the basal ration was replaced with bio-fermented feed, and the specific composition of the bio-fermented feed was:

[0029]

[0030] Comparative example, embodiment 1-5 midgut villi growth result is as follows figure 1 and shown in Table 1.

[0031] Table 1

[0032] comparative example Example 1 Example 2 Example 3 Example 4 Example 5 villi height 320.69 369.59 350.28 350.39 372.44 330.49 Crypt depth 190.59 172.39 183.39 198.49 179.18 162.10 villus height / crypt depth 1.68 2.14 1.91 1.77 2.08 2.04

[0033] It can be seen from the results that adding fermented feed can increase the height of piglet jejunum villi, reduce the depth of crypt, and increase the height of villi / depth of crypt. This shows that bio-fermented feed can improve the intestinal villi structure of piglet jejunum, improve the digestion and absorption rate of nutrients, and improve immune function.

Abstract

The invention relates to a biological fermentation feed capable of improving the digestion and absorption rate of piglets as well as a preparation method and application of the biological fermentation feed. The biological fermentation feed comprises the following components in parts by mass of 590-2400 parts of grain residues, 300-900 parts of algae, 3-15 parts of amino acids, 8-37 parts of fungi and 2-10 parts of enzymes. The preparation method comprises the following steps of fermenting the grain residues, the algae, the amino acids, the fungi and the enzymes in parts by mass in a breathing bag to obtain the biological fermentation feed for improving the digestion and absorption rate of the piglets, wherein fermentation moisture content is 30-40%, the temperature is 30-35 DEG C, and the time is 3-5 days. The biological fermentation feed is added into a basic ration of piglets and used for increasing the piglet jejunum villus height, reducing the crypt depth and increasing the villus height / crypt depth, and the adding amount of the biological fermentation feed is 5-10 wt%. Compared with the prior art, the biological fermentation feed has the advantages of improving antinutritional factors in the feed raw materials, fully utilizing agricultural and sideline products, increasing the intestinal villus height and the like.

Description

technical field [0001] The invention relates to the field of biologically fermented feed, in particular to a biologically fermented feed that improves the digestion and absorption rate of piglets, a preparation method and application thereof. Background technique [0002] Compared with growing and finishing pigs, piglets have an imperfect digestive tract, so their digestion and absorption of nutrients is not perfect. The intestine is not only the main place for digestion and absorption, but also an important immune organ. Therefore, it is of great significance to improve the integrity of the small intestine structure of nursery pigs, improve the digestion and absorption rate of nutrients, and improve the immune barrier function of the intestine. [0003] Traditionally, raw materials such as antibiotics and soybean meal are widely used in piglet diets. Studies have found that anti-nutritional factors in soybean meal, such as glycinin and plant lectins, can damage the intesti...
