Mixed feed for preventing diarrhea of weaned piglets

Abstract

The invention relates to mixed feed for preventing diarrhea of weaned piglets and a preparation method thereof. The mixed feed is prepared from the following raw materials in parts by weight: 20 to 40parts of corns, 10 to 20 parts of baken and flaked corn, 5 to 15 parts of whey powder, 5 to 15 parts of bean pulp, 5 to 8 parts of expanded soybean, 1 to 5 parts of fermented soybean pulp, 5 to 10 parts of skim milk powder, 1 to 5 parts of saccharose, 0 to 5 parts of plasma protein powder, 1 to 1.5 parts of organic compound acidifier, 0.1 to 0.4 part of a organic mineral premix, 0.1 to 0.8 part of mountain flour, 0.1 to 1.5 parts of calcium hydrogen phosphate, 0.3 to 1.5 parts of compound amino acid, 0.1 to 0.4 part of table salt, 0.05 to 0.3 part of choline chloride, 0.02 to 0.05 part of a vitamin premix, 0.05 to 0.2 part of a complex enzyme preparation, 0.05 to 0.1 part of glutamine, 0.1 to 0.2 part of glycerol monobutyrate, 0.1 to 0.3 part of a Chinese herbal medicine preparation, 0.03to 0.1 part of probiotics and 0.05 to 0.5 part of a mildew preventive. The mixed feed disclosed by the invention is capable of effectively increasing the feed intake, increasing the digestibility ofthe mixed feed, helping repair intestinal functions of piglets and build a normal intestinal microflora, effectively relieving or avoiding the diarrhea of early-weaned piglets, reducing a diarrhea rate and a death rate and realizing rapid growth of the piglets.

Description

technical field [0001] The invention belongs to the technical field of animal nutrition, and in particular relates to a compound feed for preventing diarrhea of ​​weaned piglets and a preparation method thereof. Background technique [0002] Modern pig farming generally adopts early weaning. When piglets are weaned, the body's own digestive enzyme system and intestinal absorption system are not fully developed. In addition, the material eaten by piglets in the early weaning period changes from liquid breast milk to solid feed, resulting in weaning stress in piglets. Low food intake, insufficient intake of nutrients, and high rates of diarrhea. Piglet diarrhea causes slow growth or even negative growth, decreased immunity, increased disease, and prolonged slaughter time, which brings huge losses to the pig industry. [0003] The main causes of diarrhea in weaned piglets are as follows: (1) During early weaning, the piglets are young, the digestive enzyme system of the body ...

Piglet diarrhea causes slow growth or even negative growth, decreased immunity, increased disease, and prolonged slaughter time, which brings huge losses to the pig industry

[0003] The main causes of diarrhea in weaned piglets are as follows: (1) During early weaning, the piglets are young, the digestive enzyme system of the body is not fully developed, the gastric acid secretion capacity is low, and the secretion of digestive enzymes such as pepsin and trypsin is insufficient and the activity is poor, resulting in The protein in the diet cannot be fully digested and enters the hindgut, where it is utilized by harmful microorganisms and causes a large number of harmful microorganisms to multiply, causing diarrhea; (2) The intestinal structure of piglets undergoes a huge change after weaning, the intestinal villi become shorter, and the crypts As the depth increases, the intestinal defense function decreases, resulting in poor absorption capacity of piglets, and they are easily stimulated by allergic factors in the diet to cause diarrhea; (3) In the early stage of weaning, the intestinal microflora of piglets needs to be re-established, and harmful microorganisms increase. Beneficial microorganisms are reduced, and the microbial flora is unbalanced, causing diarrhea; (4) The compound feed for weaned piglets is mostly plant-derived solid feed, which has low digestibility and provides insufficient energy for piglets, and the anti-nutritional factors in plant protein raw materials cause diarrhea. Intestinal hypersensitivity reaction in piglets, leading to diarrhea
