Problems solved by technology

[0004] In order to solve various problems existing in the existing methods for preventing salmonella infection, the present invention provides an anti-salmonella pollution-resistant laying hen compound feed and additives, which are prepared by combining biological fermentation raw materials, yeast metabolites, and plant lactobacillus. The additive, when used in feed, can significantly inhibit the growth of Salmonella, and can ensure that the detection of Salmonella in the feed is negative. It can prevent laying hens from being contaminated by Salmonella without heating process and without additional formaldehyde additives or organic acids. It has obvious antibacterial effect on both Salmonella and Escherichia coli

Embodiment 1

[0023] A compound feed for laying hens resistant to salmonella contamination, comprising the following components by mass: 580 parts of corn, 180 parts of soybean meal, 20 parts of biological fermentation raw materials, 10 parts of chili powder, 40 parts of rice bran, 10 parts of soybean oil, and 2 parts of yeast metabolites 0.5 parts of Lactobacillus plantarum, 65 parts of stone powder, 8 parts of calcium hydrogen phosphate, 2.5 parts of table salt, 0.6 parts of methionine, 0.8 parts of lysine, 1 part of choline chloride with a purity of 60%, 1.5 parts of baking soda, plant 0.1 part of acid enzyme, 0.2 part of multivitamin, 1 part of trace element.

[0024] A compound feed for laying hens resistant to Salmonella contamination, comprising the following components by mass: 635 parts of corn, 240 parts of soybean meal, 50 parts of biological fermentation raw materials, 20 parts of chili powder, 80 parts of rice bran, 20 parts of soybean oil, and 4 parts of yeast metabolites 5 pa...

Embodiment 2

[0027] The present invention adopts three raw materials of yeast metabolites, biological fermentation raw materials, and plant lactobacillus to prepare a combined solution according to the ratio in the first formula in Example 1, wherein the total concentrations of the three raw materials are 160 μg / ml and 320 μg / ml respectively , 640 μg / ml, 1280 μg / ml, 2560 μg / ml, 5120 μg / ml, and add sterile water as a blank group, add the above solution to the culture dish with Salmonella and Escherichia coli, so as to detect the three combinations used in the present invention Bacteriostatic effect of raw materials against Salmonella and Escherichia coli.

Embodiment 3

[0032] Select 153000-156000 laying hens and divide them into three groups and raise them in three chicken coops, with 51000-52000 chicken coops in each poultry coop, feed the feed ratio in Example 1, then randomly sample 500 eggs in every poultry coop, and divide 500 chicken coops The eggs were randomly divided into 13 groups, and all the eggs in each group were cracked and mixed, and samples were taken to detect Salmonella. At the same time, the feed of each chicken house was also sampled and tested, and 2 eggs were randomly sampled in each chicken house. "+" means Salmonella positive, "-" means Salmonella negative.

Abstract

The invention discloses a salmonella-pollution-resistant compound feed for laying hens. The salmonella-pollution-resistant compound feed comprises the following components: corn, soybean meal, biological fermentation raw materials, chili powder, rice bran, soybean oil, yeast metabolites, lactobacillus plantarum, mountain flour, calcium hydrophosphate, table salt, methionine, lysine, choline chloride with the purity of 60%, baking soda, phytase, composite vitamins and trace elements. According to the feed disclosed by the invention, three raw materials, namely the biological fermentation raw materials, the yeast metabolites and the lactobacillus plantarum, are combined to be used as an additive for cooperation, so that the feed can remarkably inhibit the growth of salmonella, it is ensuredthat salmonella detection in the feed is negative, and a finished feed product is not polluted in a transfer process; meanwhile, the feed laying hens can be prevented from being polluted by salmonellaunder the condition that a heating process is not needed and formaldehyde additives and organic acids are not additionally added into the feed, and the antibacterial effect on salmonella and escherichia coli is obvious.

Description

technical field [0001] The invention relates to a chicken feed, in particular to an anti-salmonella pollution-resistant laying hen compound feed and an additive. Background technique [0002] Salmonella is a general term for bacteria that parasitize in the intestinal tract of humans and animals, and whose biochemical reactions and antigenic structures are similar to those of Gram-negative bacteria. If laying hens ingest feed containing Salmonella, on the one hand, it may cause acute or chronic diseases of poultry, including pullorum, poultry typhoid and poultry paratyphoid, etc., resulting in weakness, malnutrition, fatigue and reduced resistance of the chickens, which eventually lead to production performance decline and death, on the other hand, the eggs produced by infected layer hens may also contain salmonella and affect human health. [0003] Since the processing technology of laying hen feed is relatively simple, most of the raw materials are only crushed and mixed, ...
