Problems solved by technology

In order to improve the survival rate of piglets and solve the bottleneck problem of pig breeding, researchers at home and abroad have conducted a lot of research on drug treatment, nutritional regulation, gene breeding, etc., but they still cannot solve this problem well.
[0003] Since January 2006, the European Union has completely banned the use of antibiotics as growth-promoting feed additives for food animals, and Denmark and Sweden have also banned the use of antibiotics to varying degrees, which limits the use of antibiotics

Embodiment 1

[0017] Proportion (by weight): short-chain fatty acid 50%, sodium humate 15%, glutamine 10%, Chinese herbal medicine additive 15%, wheat germ powder 10%. The above-mentioned raw materials are all dry powders with particle sizes less than 0.5 mm.

[0018] Chinese herbal medicine additives (parts by weight): hawthorn 50, astragalus 15, honeysuckle 10, licorice 15, mixed and crushed into 80-mesh dry powder.

[0019] Feeding effect:

[0020] For the experiment, 40 litters of 20-day-old DLY piglets with similar birth dates were selected for feeding experiments in Linyi Xinglong Original Breeding Pig Farm from October to December 2013. The feeding experiment was randomly divided into 4 groups with 10 litters in each group. There were 98 piglets in the first group, 96 piglets in the second group, 95 piglets in the third group, and 96 piglets in the control group. , the number of piglets and the starting age of piglets in each group were basically the same without significant di...

Embodiment 2

[0028] Proportion (by weight): short-chain fatty acid 51%, sodium humate 14%, glutamine 9%, Chinese herbal medicine additive 16%, wheat germ powder 10%. The above-mentioned raw materials are all dry powders with particle sizes less than 0.5mm.

[0029] Chinese herbal medicine additives (parts by weight): hawthorn 60, astragalus 20, honeysuckle 15, licorice 20, mixed and crushed into 100-mesh dry powder.

[0030] How to use: The feed additive is added in an amount of 2.5% of the total weight of the piglet's diet, and it is directly added to the piglet's diet.

Embodiment 3

[0032] Proportion (weight ratio): short-chain fatty acid 49%, sodium humate 16%, glutamine 10%, Chinese herbal medicine additive 14%, wheat germ powder 11%. The above-mentioned raw materials are all dry powders with particle sizes less than 0.5 mm.

[0033] Chinese herbal medicine additives (parts by weight): hawthorn 55, astragalus 18, honeysuckle 12, licorice 16, mixed and crushed into 200-mesh dry powder.

[0034] Method of use: The amount of this feed additive added is 2.0% of the total weight of the piglet's diet, and it is directly added to the piglet's diet.

Abstract

The invention discloses a feed additive for improving intestinal development of piglets and a using method thereof. The feed additive is prepared from the following raw materials: short-chain fatty acid, sodium humate, glutamine, Chinese herbal medicine additives and wheat germ powder, wherein the Chinese herbal medicine additives comprise the following components: hawthorn, astragalus membranaceus, honeysuckle and liquorice. The raw materials are compounded, the raw materials impact with one another, the intestinal benign development of the piglets is promoted, the intestinal recess depth and intestinal villus height are increased, and the feed utilization rate is increased. Meanwhile, the immunity of the piglets is enhanced, and the influence on the intestinal metabolism caused by weaning stress of the piglets is relieved, so that the growth performance and health level of the piglets are improved.

Description

technical field [0001] The invention relates to a feed additive for improving intestinal tract development of piglets and an application method thereof, belonging to the technical field of feed. Background technique [0002] The intestinal development and immune function establishment of piglets not only affect the growth performance of piglets, but also affect their growth performance during growth and fattening stages. The piglet stage refers to piglets aged 0 to 70 days. At present, the piglet mortality rate is 10-20%, the piglet diarrhea rate is 10-15%, and the death rate due to diarrhea reaches 15-20%. The piglet death due to diarrhea accounts for 39.8% of the total mortality %. In order to improve the survival rate of piglets and solve the bottleneck problem of pig breeding, researchers at home and abroad have conducted a lot of research on drug treatment, nutritional regulation, gene breeding, etc., but they still cannot solve this problem well. [0003] Since Janua...
