Problems solved by technology

However, long-term use of antibiotics in piglets will cause antibiotics to remain in piglets, leading to the emergence of antibiotic-resistant bacteria, which is not conducive to disease prevention and control

Embodiment 1

[0020] Embodiment 1: Antibacterial test in vitro.

[0021] (1) Take 5 parts by mass of cinnamaldehyde, 5 parts by mass of galangin, 7 parts by mass of kaempferol, 8 parts by mass of jatrorrhizine, and 75 parts by mass of carrier, and prepare a substitute feed additive product. Divide the experiment into 3 groups, and see Table 1 below for the grouping and the amount of antibiotics or alternative feed additives added, and a 5120 μg / ml mother solution was prepared in 20% ethanol aqueous solution.

[0022] Table 1 The use of antibiotics and alternative feed additives in test groups and in vitro antibacterial tests

[0023]

[0024] (2) Use this solution as the mother solution, and use 20% ethanol aqueous solution as the diluent to obtain the following medicinal solutions with different concentrations. The diluted mother liquor was mixed evenly without centrifugation, and the turbid solution was taken for dilution to obtain diluted concentrations of 512, 256, 128, 64, 32, 16, ...

Embodiment 2

[0031] Example 2: Experiments on improving growth performance and reducing diarrhea of ​​weaned piglets with alternative feed additives.

[0032] 1. Experimental design

[0033]120 healthy weaned piglets (23±2 days old, initial weight 7.07±0.34 kg) were selected for the experiment, and were divided into 5 groups according to the initial weight according to the complete randomized block method, with 6 repetitions in each group. 4 piglets are repeated each, half male and half female, sharing 30 circles. Among them, group A is the control group, fed with basal diet, group B added 20 g / t of anti-enemycin on the basis of basal diet, and groups C, D, and E added cinnamaldehyde and galactose on the basis of basal diet, respectively. The mixed feed additive 300g / t, 500g / t and 700g / t of gingerol, kaempferol and jatrorrhizine, the addition ratio of this mixed feed additive is 5 parts by mass of cinnamaldehyde, 5 parts by mass of galangin, and 7 parts by mass of natol, 8 parts by mass ...

Embodiment 3

[0043] Example 3: The test of improving the immune performance of weaned piglets by using anti-antibiotic feed additives.

[0044] 1. Experimental design

[0045] A total of 175 healthy weaned piglets (aged 22±3 days, initial body weight 7.89±0.23 kg) were selected and randomly divided into 5 groups, with 7 replicates in each group, 5 piglets in each replicate, half male and half female . Among them, group A is the blank control group, fed with basal diet, group B added 20 g / t of anadrenin on the basis of basal diet, and groups C, D, and E added cinnamaldehyde, The mixed feed additives of galangin, kaempferol and jatrorrhizine are 300g / t, 500g / t and 700g / t, and the addition ratio of the mixed antibiotic feed additive is 6 mass parts of cinnamaldehyde, 6 mass parts of galangin, 7 parts by mass of kaempferol, 8 parts by mass of jatrorrhizine, and 73 parts by mass of carrier. In the test, chlortetracycline 75g / t, olaquindox 100g / t and enramycin 10g / t were added to each group, ...

Abstract

The invention discloses an anti-feed additive for relieving the post-weaning stress of a piglet and a preparation method thereof and aims to solve the problems that the weanling stress is easy to occur after the piglet is artificially weaned; the nutrition dyspepsia results in diarrhea; the feed conversion rate and the immunity are reduced. Cinnamyl aldehyde, galangin, kaempferol and jateorhizine as components of the anti-feed additive are extracted from natural plants and not only can replace part of antibiotics of weaned piglet feed, but also have a good antibacterial effect after entering a piglet intestine, so that the intestinal micro-ecological balance can be maintained, the digestion and the absorption of intestinal nutrients are promoted, the body immune performance of the piglet is regulated, the growth and development levels of the piglet are improved, the post-weaning piglet diarrhea is reduced, and the post-weaning stress of the weaned piglet is effectively relived finally. Therefore, the economic benefits of the pig farming industry are improved.

Description

technical field [0001] The invention relates to an antibiotic-replacement feed additive for relieving weaning stress of piglets and a preparation method thereof, in particular to an antibiotic-replacement feed additive for improving growth performance and immune performance of weaned piglets, reducing diarrhea of ​​weaned piglets and alleviating weaning stress and its preparation method. Background technique [0002] In modern intensive pig farming, weaned piglets after 21-28 days are generally artificially weaned, so that sows can enter the next breeding period earlier and faster, reduce the chance of piglets being infected with maternal diseases, promote piglet growth, and improve breeding quality. economic benefits. After artificial weaning, the diet of piglets suddenly changed from breast milk to solid pellet feed, and the piglets were forced to separate from the sow. The development of the digestive system and immune system of the weaned piglets has not fully adapted t...
