Problems solved by technology

However, early weaning of piglets can easily lead to unsound digestive function, insufficient secretion of gastric acid and digestive enzymes, and imbalance of digestive tract flora, resulting in low utilization of plant protein and starch and nutritional stress; it is easy to cause intestinal dysfunction in piglets, The height of the intestinal villi of piglets decreases, and the depth of crypts deepens, thereby reducing the area for digestion and absorption of piglets' digestive tract, which in turn affects the growth performance of piglets

preparation example Construction

[0034] The preparation method of the above-mentioned feed premix may include the following steps: mixing silage straw, intestinal membrane protein, citric acid, glucose, oregano extract, brewer's yeast, salt and carrier according to the ratio, that is, mixing the raw material components according to the ratio.

[0035] The feed premix mentioned above can be added to the feed of weaned piglets to improve the intestinal function of the weaned piglets, regulate intestinal health, enhance immunity and improve the growth performance of piglets. For reference, the feed premix can be added to the feed of weaned piglets at a mass percentage of 1-1.5%, for example.

Embodiment 1

[0038]The feed premix containing 20 parts by weight of silage stalks, 15 parts by weight of intestinal membrane protein, 10 parts by weight of citric acid, 10 parts by weight of glucose, 4 parts by weight of oregano extract, 5 parts by weight of feed premix per 100 parts by weight Brewer's yeast and 2 parts by weight of salt, the balance is defatted rice bran and mix the above raw materials to obtain a feed premix that increases the height of piglet intestinal villi and reduces the depth of crypts.

[0039] Among them, the silage straw is obtained by the following method: mix straw, green juice fermentation liquor and cellulase in the ratio of 1.5mL / kg green juice fermentation broth and 2500U cellulase in a vacuum bag, and then add a small amount of water, air pumping, sealing, and anaerobic fermentation at room temperature for 60 days. The above-mentioned cellulase is a cellulase with an enzyme activity of 20000 U / g sold by Guangdong VTR Company.

[0040] The green juice fer...

Embodiment 2

[0043] The difference between this embodiment and Example 1 is that every 100 parts by weight of feed premix contains 40 parts by weight of silage straw, 35 parts by weight of intestinal membrane protein, 25 parts by weight of citric acid, 20 parts by weight of glucose, 9 parts by weight of oregano extract, 10 parts by weight of brewer's yeast and 5 parts by weight of salt, and the balance is defatted rice bran.

Abstract

The invention relates to a feed premix capable of increasing piglet villus height and reducing crypt depth as well as a preparation method and an application thereof, the feed premix belongs to the technical field of feed. Every 100 parts by weight of the feed premixing agent comprises 20-40 parts by weight of silage straw, 15-35 parts by weight of dried porcine soluble, 10-25 parts by weight of citric acid, 10-20 parts by weight of glucose, 4-9 parts by weight of an oregano extract, 5-10 parts by weight of saccharomyces cerevisiae, 2-5 parts by weight of salt and the balance of carriers. Thecontent of effective viable bacteria in every g of saccharomyces cerevisiae is 7*10<9>-7.5*10<9> CFU. The feed premix has no drug resistance, and has better and stable effects after all raw materialsare matched for use. According to the preparation method, all raw materials are mixed in parts, simple and quick, the feed has good stability. After the feed premix is added to the feed of weaned piglets, the intestinal function of piglets can be improved, the intestine healthy of piglets is regulated, the immunity of piglets is strengthened and the growing performance of piglets is effectively improved.

Description

technical field [0001] The invention relates to the field of feed, and in particular to a feed premix for increasing the height of piglet intestinal villi and reducing the depth of crypts, as well as its preparation method and application. Background technique [0002] With the continuous improvement of the intensification of pig breeding, early weaning of piglets has become a technical measure to improve breeding efficiency. However, early weaning of piglets can easily lead to unsound digestive function, insufficient secretion of gastric acid and digestive enzymes, and imbalance of digestive tract flora, resulting in low utilization of plant protein and starch and nutritional stress; it is easy to cause intestinal dysfunction in piglets, The height of intestinal villi of piglets decreased, and the depth of crypts deepened, thereby reducing the area for digestion and absorption of piglets' digestive tract, which in turn affected the growth performance of piglets.
