Problems solved by technology

[0005] Although putrescine, xylanase, gallic acid and cinnamaldehyde all have certain anti-diarrhea effects, the growth-promoting effect is not obvious, and the single addition cost is high, so it cannot replace antibiotics

Embodiment

[0022] According to the ratio of 10:4:2:1, putrescine, gallic acid, xylanase, and cinnamaldehyde (all commercially available products) were evenly compounded to prepare piglet anti-diarrhea and growth-promoting feed additives. (purchased from a feed factory in Hebei Province) was added with 850 grams of anti-diarrhea growth-promoting feed additive for piglets, and mixed evenly.

[0023] Select 120 three-way weaned piglets of the same breed and weight at 25 days old, and set up 2 treatments in the experiment, with 10 repetitions for each treatment, and 6 piglets for each repetition. On the basis of the control group, additives prepared in this embodiment were added. From weaning to 42 days after weaning, the test period was 42 days. On the day of the end of the experiment, one piglet was selected from each pen for slaughter and sampling, and the jejunum and ileum segments were collected to measure the villus height and crypt depth, and calculate the ratio of villus height to c...

Abstract

The invention provides a piglet diarrhea-resisting growth-promoting feed additive. The piglet diarrhea-resisting growth-promoting feed additive is prepared from the following components in parts by weight: 2.5 to 12.5 parts of putrescine, 1 to 5 parts of gallic acid, 1 to 4 parts of xylanase and 0.5 to 2.5 part of cinnamyl aldehyde.

Description

technical field [0001] The invention relates to the field of animal husbandry production, in particular to the field of pig production, and in particular to a piglet anti-diarrhea growth-promoting feed additive and a preparation method thereof. Growth effect. Background technique [0002] China is a big pork producer and also a big consumer. China's per capita pork consumption accounts for about two-thirds of all meat consumption. Pig production plays a very important role in people's livelihood and national economy. It has been a long-standing goal in this field to raise my country's pig production level to the international leading level. [0003] Weaning is one of the most critical stages of pig production. Weaning stress can cause gastrointestinal disorders and decreased immune resistance, which can lead to diseases such as intestinal inflammation and diarrhea. According to statistics worldwide, infectious diseases and diarrhea in piglets during the weaning stage are ...
