Problems solved by technology

However, the use of traditional methods such as antibiotics will lead to an imbalance in the intestinal flora of weaned piglets, and cause many negative effects such as drug residues and drug resistance enhancement, which has been unable to fundamentally solve the problem of piglet intestinal health

Embodiment 1-4

[0033] 1.1 Experimental design

[0034] In this experiment, a single factor design was adopted, and 150 28-day-old Du Sanyuan pigs with similar body weight and consistent health status were selected and randomly divided into 5 groups, with 3 replicates in each group and 10 pigs in each replicate. The control group was fed with basal rations (see Table 1-1, Table 1-2), and the basal rations were fed with reference to the nutritional requirements of NRC (2012) pigs in the United States. Embodiment 1-4 groups were fed with basal rations+different formula feed additives respectively (See Table 2), the test period was 28 days, and food and water were ad libitum during the test.

[0035] 1.2 Measuring indicators

[0036] 1.2.1 Production performance

[0037] The test pigs were weighed at the beginning and end of the test, and the average daily gain was calculated; at the start and end of the test, the feed consumption of the test pigs was settled with each repetition as a unit, an...

Embodiment 5

[0067] A feed additive for improving intestinal health of weaned piglets. The feed additive comprises the following components and contents in parts by weight: 40 parts of lactobacillus, 40 parts of tributyrin and 10 parts of β-mannanase.

[0068] Among them, lactobacillus is fermented by lactic acid bacteria in a culture solution with a pH value of 6.5, and the enzyme activity of β-mannanase is 35000U / g.

[0069] The preparation method of the feed additive comprises the following steps:

[0070] 1) Pass lactobacillus, tributyrin and β-mannanase through 80-mesh sieve respectively;

[0071] 2) Mix lactobacillus, tributyrin and β-mannanase evenly to obtain the feed additive.

[0072] Among them, the preparation method of lactobacillus is as follows: under anaerobic conditions, add lactic acid bacteria into the culture solution with a pH value of 7 to ferment for 36 hours, and then undergo ammonium sulfate precipitation, dialysis, and concentration to obtain lactobacillus.

Embodiment 6

[0075] A feed additive for improving intestinal health of weaned piglets. The feed additive comprises the following components and contents in parts by weight: 60 parts of lactobacillus, 20 parts of tributyrin and 25 parts of β-mannanase.

[0076] Among them, lactobacillus is fermented by lactic acid bacteria in a culture solution with a pH value of 7, and the enzyme activity of β-mannanase is 45000U / g.

[0077] The preparation method of the feed additive comprises the following steps:

[0078] 1) Pass lactobacillus, tributyrin and β-mannanase through 80-mesh sieve respectively;

[0079] 2) Mix lactobacillus, tributyrin and β-mannanase evenly to obtain the feed additive.

[0080] Among them, the preparation method of lactobacillus is as follows: under anaerobic conditions, add lactic acid bacteria into the culture solution with a pH value of 6.5 to ferment for 60 hours, and then undergo ammonium sulfate precipitation, dialysis, and concentration to obtain lactobacillus.

Abstract

The invention relates to a feed additive for improving the intestinal health of weaned piglets, and preparation and application thereof. The feed additive comprises the following components in parts by weight: 40-60 parts of lactein, 20-40 parts of tributyrin and 10-25 parts of beta-mannase. When in preparation, firstly, the lactein, the tributyrin and the beta-mannase are respectively sieved withan 80-mesh sieve, and then the lactein, the tributyrin and the beta-mannase are uniformly mixed. When in application, the feed additive is added into the basic ration of weaned piglets, and the addition proportion of the feed additive is 2-4 percent by weight. Compared with the prior art, the feed additive can enhance the ability of inhibiting the growth of pathogenic microorganisms, promote thegrowth of probiotics, effectively improve the intestinal development condition of piglets, relieve the damage to intestinal tissues caused by the stress, maintain and give full play to intestinal functions, and finally improve the growth performance and health level of piglets, and is green and safe, and stable in performance.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and relates to a feed additive for improving intestinal health of weaned piglets and its preparation and application. Background technique [0002] The health of piglets is largely affected by the health of their intestines, because the intestines of piglets are an important place for digestion and absorption of nutrients, and play an extremely important role in maintaining the normal and healthy growth and development of piglets. At present, with the development of the pig industry in the direction of scale and intensification, the early weaning technology of piglets has been widely used in major pig farms. Weaning will bring great stress to piglets. At this stage of early weaning, the development of the digestive tract of piglets is not perfect, and various physiological functions are not perfect. They are more sensitive to changes in various external factors, and Due to changes in nutrien...
