Description
Technical Field
The invention relates to the technical field of poultry feed, in particular to a poultry compound feed and a preparation method thereof.
Background
The term "feed" is a general term for food of animals kept by all people, and generally, the term "feed" mainly refers to food of animals kept in agriculture or animal husbandry. It is often desirable that animals consume minimal feed in a minimal amount of time and are able to grow healthily and rapidly. The antibiotics can reduce the disease incidence caused by bacterial infection, promote the healthy growth of animals and improve the production performance of the animals, and are commonly used additives in pig and poultry feeds at present.
However, the problem of antibiotic residue in livestock and poultry products is serious due to the large use of antibiotics, and the antibiotic residue not only directly produces acute and chronic toxic effects on animals to cause the increase of bacterial drug resistance, but also indirectly causes potential harm to human health through the effects of the environment and food chain.
The occurrence of these problems has led to the use of antibiotic additives in animal feed being limited or banned, and therefore, reducing the use of feed antibiotics and finding suitable antibiotic replacement products are of great significance to the animal husbandry industry.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide the compound feed for the poultry, which does not contain antibiotics, can also reduce the morbidity of the poultry and has the effect of promoting the rapid growth of the poultry.
The technical purpose of the invention is realized by the following technical scheme:
a compound feed for poultry comprises the following components in parts by weight: comprises 650 parts of 550-650 parts of corn, 15-26 parts of vegetable oil, 250 parts of 140-250 parts of soybean meal, 30-45 parts of wheat middling, 40-60 parts of corn by-product, 35-55 parts of corn protein powder, 9-15 parts of calcium hydrophosphate, 14-22 parts of stone powder, 2-5 parts of sodium chloride, 2-7 parts of lysine, 0.3-0.7 part of enzyme preparation and 1-3 parts of substitution-resistant composition; wherein, the anti-displacement composition comprises the following components: 0.2 to 0.4 portion of medium-chain fatty acid, 0.3 to 0.5 portion of probiotics and 0.5 to 1.0 portion of astringent.
By adopting the technical scheme, as the component with the largest content in the main material, the corn contains rich nutrient substances such as protein, fat, vitamins, trace elements, cellulose and the like, and is an important raw material for preparing the poultry feed. The corn protein powder has protein as main component and can provide rich protein for poultry. The bean pulp is rich in protein, oil, amino acid, etc. The raw materials rich in protein are selected as the main materials of the raw materials, so that the growth of the poultry can be promoted. The stone powder contains a large amount of calcium carbonate, so that sufficient calcium is provided for the generation of poultry, and the growth of bones of the poultry is promoted. Calcium hydrogen phosphate mainly provides mineral substance nutrition such as phosphorus, calcium and the like for the feed, and the poultry are easy to digest and absorb, so that the growth and development of the poultry can be accelerated, the fattening period is shortened, and the weight is rapidly increased; meanwhile, the feed additive has the function of enhancing the disease resistance and cold resistance of poultry and has the function of preventing and treating chondropathy, white diarrhea and paralysis diseases of the poultry.
The sodium chloride keeps the osmotic pressure balance between cells and blood, the sodium can maintain the acid-base balance between the blood and tissue fluid, regulate the stability of normal osmotic pressure, stimulate the secretion of saliva, promote the appetite of poultry, increase the feed intake of poultry and improve the growth speed of poultry.
Lysine plays an important physiological role in the body, and its absence will directly or indirectly affect the growth, reproduction and development of birds. The amino acids contained in corn and soybean meal cannot meet the needs of poultry, but are deficient in essential amino acids. Lysine is an indispensable component of a synthetic protein, and the lack of amino acid easily causes the reduction of protein synthesis in a body, thereby causing the problems of protein metabolism and related enzyme synthesis in the body and leading to the slow growth of poultry. Lysine is added into the feed to meet the requirement of the poultry on lysine, and the synthesis of protein is increased, so that the rapid growth of the poultry is promoted.
The enzyme preparation is a protein with bioactive substances, has high efficiency and specificity on the action of a substrate, can effectively degrade antinutritional factors in the feed, ensures the quality of the feed, improves the utilization rate of nutritional ingredients of the feed, and can improve the intestinal microbial flora structure of poultry.
The antibacterial composition formed by adding medium-chain fatty acid, probiotics and an astringent has broad-spectrum antibacterial effect. The anti-bacteria composition containing the three components replaces the feed prepared by antibiotics, and can reduce diseases of poultry caused by bacterial infection after being eaten by the poultry, improve the diarrhea problem of the poultry and effectively promote the healthy growth of the poultry. In addition, the feed can improve the utilization rate of the poultry to nutrient components in the feed, promote the weight gain of the poultry and improve the conversion rate of the feed.
The medium-chain fatty acid has a good antibacterial effect, can affect the intestinal environment, effectively improve intestinal flora, improve the digestion of poultry on protein and fiber, promote the utilization rate of poultry on effective components in feed, and increase the weight gain speed of poultry. The medium-chain fatty acid also has antiviral property, and can reduce the toxicity of specific pathogenic bacteria, thereby improving the immunity of poultry and reducing the disease rate of poultry.
The probiotics can be adhered to intestinal wall cells of the poultry to play a barrier role, competitively inhibit and repel pathogenic bacteria, improve the intestinal environment of the poultry, inhibit the growth of harmful bacteria, maintain the flora balance of the intestinal tract of the poultry and improve the production performance of animals. Meanwhile, the existence of the probiotics reduces harmful microorganisms in intestinal tracts of the poultry, reduces the consumption of the probiotics to nutrients, and greatly reduces the occurrence of digestive tract diseases, particularly diarrhea of the poultry. In addition, probiotics are matched with medium-chain fatty acid, and the medium-chain fatty acid is used as an energy source, so that an environment which is not beneficial to proliferation of pathogenic bacteria is created, and harmful substances in intestinal tracts of poultry are further reduced.
The probiotics is a good immune activator, can stimulate the growth and development of intestinal immune organs, improve the antibody level of poultry, enhance the immune function of organisms and greatly reduce the morbidity and mortality of poultry.
The probiotics can also provide various substances beneficial to the growth and development of poultry organisms, such as vitamins, amino acids, amylase, protease and the like, and other growth promoting substances. The probiotics can generate high vitamin B1, vitamin B2, vitamin B6 and various amino acids in the growth and reproduction process, provide vitamin nutrition and protein for poultry intestines, and effectively promote the growth speed of the poultry.
The astringent has astringent effect, can solidify surface protein of intestinal mucosa to form a protective film, and has effects of relieving intestinal irritation and enterokinesia, astringing, and relieving diarrhea, effectively solving diarrhea problem of fowls, increasing feed absorption rate of fowls, and increasing growth speed of fowls. In addition, the astringent has the effects of astringing and inducing astringency, so that the constipation of the poultry is easily caused by excessively large dosage, and the medium-chain fatty acid and the probiotics can improve the intestinal environment, maintain the balance of flora in the intestinal tract and improve the constipation.
The medium-chain fatty acid, the probiotics and the astringent are matched, so that the diarrhea problem of the poultry is effectively reduced, the immunity is improved, the morbidity of the poultry is reduced, and the healthy and rapid growth of the poultry is promoted.
The present invention in a preferred example may be further configured to: the weight ratio of the medium-chain fatty acid to the probiotics to the astringent is 1: (0.8-1.6): (1.5-2.5).
By adopting the technical scheme, experiments show that the weight ratio of the medium-chain fatty acid to the probiotics to the astringent is 1: (0.8-1.6): (1.5-2.5), the incidence of poultry is low and the growth rate is high. The reason for this analysis is probably because although probiotics can improve the intestinal environment, the excessive probiotics easily make the intestinal tract gradually lose the ability of self-breeding beneficial bacteria, and the probiotics are dependent. In addition, excess probiotic bacteria can unbalance the bacterial species in the bird, causing new infections. Excessive use of astringents tends to cause constipation, while excessive intake of medium-chain fatty acids can increase calories, affect cholesterol levels, cause intrahepatic deposition of cholesterol, hinder hepatic glycogen synthesis, and reduce liver function. Thus, the weight ratio of medium chain fatty acids, probiotics and astringent is 1: (0.8-1.6): (1.5-2.5), the synergistic effect of the three components reduces the incidence of diseases of poultry and increases the growth rate.
The present invention in a preferred example may be further configured to: the astringent contains zinc oxide and tannase protein, and the weight ratio of the zinc oxide to the tannase protein is (0.9-1.3): 1.
by adopting the technical scheme, experiments show that the weight ratio of the zinc oxide to the tanned protein is (0.9-1.3): 1, the astringent has the best antibacterial and antidiarrheal effects. The reason for this is probably because molecular zinc oxide has the effect of inhibiting bacterial growth, and can prevent diarrhea of poultry when added into feed, and has good astringency. However, zinc oxide is easily dissociated into ionic zinc in the stomach by gastric acid, so that a large amount of zinc ions enter the intestinal tracts of poultry to cause zinc poisoning, and a small amount of molecular zinc oxide cannot achieve the expected antibacterial and antidiarrheal effects. The zinc oxide is matched with the tanned protein, and the tanned protein is not decomposed in the stomach, so that the zinc oxide is coated to a certain extent, the dissociation degree of the zinc oxide in the stomach is effectively reduced, more molecular zinc oxide enters the intestinal tract, and the effects of bacteriostasis and diarrhea stopping are further achieved. Meanwhile, the tannase is decomposed in the intestinal tract to generate tannic acid, and the tannic acid has an astringent effect, so that the tannase and the zinc oxide are cooperatively matched to effectively prevent the poultry diarrhea. In addition, the tannase protein has the function of detoxification, and the weight ratio of the zinc oxide to the tannase protein is (0.9-1.3): 1, under the action of ensuring the functions of bacteriostasis and diarrhea stopping, the zinc poisoning caused by excessive free zinc can be effectively prevented, and the metabolic balance of trace elements of poultry is ensured.
The present invention in a preferred example may be further configured to: the medium-chain fatty acid adopts lauric acid.
By adopting the technical scheme, lauric acid is a typical amphiphilic molecule, and the affinities of the head end and the tail end are quite different. The molecular head is polar gene and hydrophilic. The tail part is a hydrocarbon chain, is lipophilic and is easy to form micelles in solution. The medium-chain fatty acid is matched with the zinc oxide, so that the zinc oxide can be wrapped inside the micelle, the decomposition condition of the zinc oxide in the stomach is reduced, the utilization rate of the zinc oxide is improved, and the antidiarrheal function of the zinc oxide is improved.
The present invention in a preferred example may be further configured to: the raw materials also comprise 0.3 to 0.8 weight portion of anticoccidial drug.
By adopting the technical scheme, the coccidiosis is a parasitic disease, and can cause serious loss in the production of poultry meat and eggs. The multiplication of parasites in the small intestine results in the prevention of damage, reduction in feed intake and absorption of nutrients in the feed, dehydration and blood loss. The feed added with the anticoccidial drug can reduce the probability of poultry infected with coccidiosis, thereby ensuring that the poultry can grow healthily and rapidly.
The present invention in a preferred example may be further configured to: the probiotic bacteria are one or more of clostridium butyricum, lactic acid bacteria, bacillus subtilis, bacillus licheniformis and lactobacillus acidophilus.
By adopting the technical scheme, the clostridium butyricum can repair damaged intestinal mucosa, restore the balance of intestinal flora and has good effect of improving diarrhea. In addition, the clostridium butyricum decomposes polysaccharide in food into oligosaccharide, promotes the rapid growth of other beneficial bacteria in intestinal tracts, and is equivalent to the action of multi-connected bacteria.
The lactobacillus can promote absorption of protein, monosaccharide and nutrients such as calcium and magnesium, generate a large amount of beneficial substances such as vitamin B group, and increase growth rate of poultry.
The bacillus subtilis is an aerobic bacterium, needs to consume a large amount of oxygen in the growth process, and the environment is favorable for the growth of anaerobic bacteria such as lactic acid bacteria, bifidobacteria and the like, and inhibits the reproduction of aerobic enterobacteria, thereby reducing the occurrence of digestive tract diseases.
Bacillus licheniformis can regulate dysbacteriosis to achieve therapeutic effect, and can promote organism to produce antibacterial active substance and kill pathogenic bacteria. Can produce active resisting matter, has unique biological oxygen-taking action mechanism and can inhibit the growth and propagation of pathogenic bacteria.
Lactobacillus acidophilus has antagonistic effect on pathogenic microorganisms, and can regulate intestinal flora balance and inhibit proliferation of intestinal undesirable microorganisms.
The present invention in a preferred example may be further configured to: the enzyme preparation adopts one or more of amylase, protease, xylanase, mannase, cellulase and pectinase.

Feeding experiment
3600 healthy and disease-free broilers with the same variety, the weight average of the body weight of 1000 +/-10 g and normal growth and development are selected, and the variety is AA white feather broilers. 3600 broilers were equally divided into 18 groups of 200 broilers each, which were placed in 18 henhouses in the same environment, and fed with the feeds of examples 1-13 and comparative examples 1-5, respectively, for an experimental period of 20 days. The feed was timed to 2 times at 8:30 am and 5:30 pm daily. The disease number of broilers within 20 days and the average daily gain per broilers in each group were analyzed and the results are shown in table 1.
TABLE 1 feed test results
| Number of patients | Daily gain (g) | |
| Example 1 | 6 | 60.5 |
| Example 2 | 5 | 62.6 |
| Example 3 | 7 | 58.1 |
| Example 4 | 4 | 64.9 |
| Example 5 | 3 | 67.2 |
| Example 6 | 2 | 69.5 |
| Example 7 | 3 | 67.1 |
| Example 8 | 1 | 76.2 |
| Example 9 | 0 | 80.0 |
| Example 10 | 1 | 76.7 |
| Example 11 | 3 | 66.9 |
| Example 12 | 2 | 69.7 |
| Example 13 | 3 | 66.6 |
| Comparative example 1 | 5 | 62.0 |
| Comparative example 2 | 7 | 57.6 |
| Comparative example 3 | 4 | 64.4 |
| Comparative example 4 | 3 | 67.1 |
| Comparative example 5 | 20 | 43.9 |
According to the table 1, compared with the comparative example 5, when the feed prepared in the examples 1 to 13 is used for feeding the broilers, the disease number of the broilers can be reduced, and the daily gain of the broilers can be increased.
Combining example 2 and example 4, it can be seen that the lauric acid adopted by the medium-chain fatty acid can reduce the disease number of the broiler chicken and improve the daily gain of the broiler chicken. The lauric acid is a typical amphiphilic molecule and can form micelle in a solution, so that zinc oxide is wrapped inside micelles of the lauric acid, the proportion of the zinc oxide decomposed in the stomach of the broiler chicken is reduced, the molecular zinc oxide is increased, the zinc oxide entering the intestinal tract is increased, the effect of inhibiting the growth of bacteria is better exerted, the immunity of the broiler chicken is improved, and the problem of diarrhea of the broiler chicken is better solved.
As can be seen by combining examples 4-7 and comparative examples 1-2, the weight ratio of medium chain fatty acids, probiotics and astringents in the replacement anti composition was in the range of 1: (0.8-1.6): (1.5-2.5), the disease number of the broiler chickens can be effectively reduced, and the daily gain of the broiler chickens is increased. This is because the excess of medium-chain fatty acids affects cholesterol levels, while the excess of probiotics unbalance strains in the broiler body to cause infection, and the excess of astringents causes constipation, so the ratio of medium-chain fatty acids, probiotics and astringents is 1: (0.8-1.6): (1.5-2.5) can mutually promote and act synergistically to improve the immunity of the broiler chickens, so that the feed intake of the broiler chickens is improved, and the growth speed of the broiler chickens is increased.
By combining the examples 4 and 8-10, the zinc oxide and the tannate protein as astringents can greatly reduce the disease number of the broiler chicken and improve the daily gain of the broiler chicken. The zinc oxide is matched with the tannalbin, so that on one hand, the tannalbin is not decomposed in the stomach and can wrap the zinc oxide, the decomposition ratio of the zinc oxide in the stomach is reduced, more zinc oxide enters the intestinal tract, and the effects of bacteriostasis and diarrhea stopping are achieved; on the other hand, the tannic acid protein can be decomposed to generate tannic acid after entering the intestinal tract, the tannic acid has the antibacterial and antidiarrheal effects, and the tannic acid and the zinc oxide are matched to synergistically play the antibacterial and antidiarrheal effects, improve the intestinal environment of the broiler chicken and enhance the immunity of the broiler chicken.
Combining examples 8-9 and comparative examples 3-4, it can be seen that the weight ratio of zinc oxide to tannalbin is (0.9-1.3): 1, the disease number of the broiler chickens can be reduced, and the daily gain of the broiler chickens is increased. This is because the coating effect of the excessive tannase protein on the zinc oxide is better, so that the speed of the zinc oxide playing the role of bacteriostasis and diarrhea checking in the intestinal tract is slower. When the amount of the tannase is too small, the coating effect on the zinc oxide is poor, so that a large amount of the zinc oxide is decomposed in the stomach, and the zinc oxide entering the intestinal tract is less, so that the effects of bacteriostasis and diarrhea stopping cannot be achieved.
Combining with the examples 4 and 11-13, it can be seen that the addition of the coccidiostat can effectively reduce the number of broilers suffering from diseases and increase the daily gain of the broilers. The reason is that the adding of the coccidiostat can reduce the probability of coccidiosis infection of the broilers, keep the intestinal tracts of the broilers with good peristaltic activity, increase the absorption of the broilers on nutrient components in the feed and improve the growth speed of the broilers.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
