Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of feed, in particular to a pigeon health-care feed based on natural plant extracts and a preparation method thereof. BACKGROUND

[0002] In the field of breeding of weaned pigeons, traditional feed mainly relies on basic energy and protein raw materials such as corn and soybean meal, and adds minerals to meet the nutritional needs, but there are significant defects. First, because the immunity of weaned pigeons is relatively weak, they are easily attacked by diseases such as trichomoniasis and salmonella, and antibiotics or chemically synthesized drugs are generally relied on for prevention and control in breeding, which not only brings about drug residues and food safety risks, but also aggravates the problem of drug resistance, which is contrary to the development trend of green and healthy breeding.

[0003] Moreover, in the intensive breeding of weaned pigeons, it is crucial to provide balanced and efficient utilization of mineral nutrients, especially calcium needed for rapid skeletal development. Currently, inorganic calcium sources such as pearl shell powder and stone powder are commonly added to feed as the main calcium supplement. However, such inorganic calcium has a significant bioavailability bottleneck, with generally low absorption rate, resulting in a large amount of unabsorbed calcium waste, and even possibly interfering with the absorption of other mineral elements or causing intestinal discomfort. In addition, in order to meet the needs of trace elements (such as iron, zinc, copper, manganese, etc.), inorganic salts (such as sulfate, oxide) need to be added to the feed. These inorganic forms of trace elements are easily interacted with (such as combined with phytic acid and fiber) in the digestive tract, forming insoluble complexes, further reducing their bioavailability, making it difficult to ensure that pigeons can fully absorb and utilize even with sufficient addition.

[0004] On the other hand, weaned pigeons may come into contact with heavy metals (such as lead, cadmium) through feed or environment during growth, and the accumulation of these harmful substances in the body poses a potential threat to health, while conventional feed formulations lack effective ingredients to actively promote the excretion of these toxins.

[0005] Therefore, the existing technology is difficult to meet the needs of weaned pigeon health breeding in both efficient utilization of minerals and active removal of harmful substances in the body, and there is an urgent need to develop new feed additives that can improve the overall bioavailability of minerals and have health protection functions. SUMMARY

[0006] The present application provides a pigeon health-care feed based on natural plant extracts, which has excellent chelating ability by using modified pearl shell powder, not only improving the absorption efficiency of minerals to promote the growth of weaned pigeons, but also chelating harmful heavy metals in the body; the synergistic effect of each component can significantly improve the survival rate of weaned pigeons and promote their growth, ensuring their health.

[0007] Therefore, it is necessary to provide a pigeon health-care feed based on natural plant extracts, raw materials including the following components in mass fraction:

[0008]

[0009]

[0010] The modified pearl shell powder is a product coupled by pearl shell powder and citric acid.

[0011] Further, the plant extract is selected from one or more of grape extract, wolfberry leaf extract, sophora leaf extract and elm leaf extract.

[0012] Specifically, the grape extract contains polyphenol antioxidant substances, which can scavenge free radicals; the wolfberry leaf and sophora leaf extract are rich in amino acids and flavonoid ingredients, which can enhance the body's immunity; and the elm leaf extract contains dietary fiber, which can improve the intestinal flora environment.

[0013] Further, the plant oil is at least one of peanut oil, soybean oil, rapeseed oil and sunflower seed oil.

[0014] Further, the additive is selected from one or more of a compound enzyme and a vitamin.

[0015] Specifically, the compound enzyme can decompose cellulose and hemicellulose in the feed, improve the digestibility of corn meal and plant protein, and reduce the intestinal burden.

[0016] Further, the plant protein is selected from one or more of sunflower meal, safflower seed cake and soybean meal.

[0017] Further, the vitamin is selected from one or more of vitamin A, vitamin B1, vitamin B2, vitamin B6, vitamin B12, vitamin C, vitamin D, vitamin E, vitamin H, vitamin K, folic acid, nicotinic acid, calcium pantothenate, inositol and choline.

[0018] Further, the mineral is selected from one or more of sodium chloride, cobalt chloride, magnesium sulfate, zinc sulfate, copper sulfate, iron sulfate, sodium phosphate, potassium phosphate, calcium phosphate and potassium iodate.

[0019] Further, the particle size of the pearl shell powder is 30-100 nm.

[0020] The application also provides a preparation method of the pigeon health-care feed based on natural plant extracts, including the following steps:

[0021] S1, mixing the pretreated pearl shell powder with citric acid, heating and reacting to obtain modified pearl shell powder;

[0022] S2, mixing the modified nacrite powder with other ingredients to obtain the pigeon health-care feed based on natural plant extract.

[0023] Further, in step S1, the pretreatment step is: soaking the nacrite powder in sodium hydroxide solution, and then performing ball milling treatment.

[0024] Further, in step S1, the heating reaction temperature is 35-45℃.

[0025] The present application has the following beneficial effects:

[0026] The pigeon health-care feed based on natural plant extract of the present application is compounded by corn powder, plant protein, plant extract, modified nacrite powder, mineral substance and additive; first, the nacrite is treated by sodium hydroxide solution, and then reacted with citric acid to introduce citric acid into the modified nacrite powder, thereby obtaining the modified nacrite powder.

[0027] Since citric acid is introduced into the modified nacrite powder, a large number of carboxyl groups are introduced onto the surface of the modified nacrite powder, so that the modified nacrite powder has excellent chelating ability, can simultaneously chelate multiple mineral substances and produce steric hindrance to avoid contact between the mineral substances, and form chelates with stable structure and good solubility; after being ingested by pigeons, the stable structure can avoid the inhibition of absorption between the mineral substances (such as calcium inhibiting the absorption of iron in the intestinal tract, reducing the absorption rate of iron), so that the mineral substances chelated on the modified nacrite powder are more easily absorbed in the digestive tract, significantly improving the absorption rate of the mineral substances, thereby ensuring the intake of mineral substances by the squab and solving the problem of squab bone development.

[0028] In addition, the un-decomposed modified nacrite powder in the body can continuously chelate with harmful heavy metal ions in the pigeon body to form stable chelates, avoid the absorption of heavy metal ions by the intestinal tract of the squab, and be excreted out of the body through feces and urine, effectively reducing the load of heavy metals in the squab body and reducing the damage to the body caused by the intake of heavy metal ions, thereby ensuring the healthy growth of the squab.

[0073] Test Example 1

[0074] The feeding effects of the feeds prepared in Examples 1-3 and Comparative Examples 1-2 were tested.

[0075] Test method: 100 0-5 day old milk pigeons were used as a group, five groups were set up, and each group of milk pigeons was fed with the feed prepared in Examples 1-3 and Comparative Examples 1-2, respectively, under the conditions of an environmental temperature of 37°C and a humidity of 60%, and the feeding period was 5 days.

[0076] Feeding method: 10 g of feed was mixed with 26 ml of distilled water in a ratio of 1:2.6, and stirred uniformly, and artificial feeding was performed using a mechanical feeder, feeding every 2 h, for a feeding time of 6:00-22:00. When artificial feeding was performed, the degree of crop distension of the gosling was taken as a reference standard for the state of natural feeding by the parent gosling.

[0077] After 5 days, the survival rate, average weight, and health status of the goslings in each group were calculated and observed.

[0078] The test results are shown in Table 1.

[0080]

[0081] According to Table 1, it can be concluded that the modified pearl shell powder used as a component of the feed in the examples of the present application can enable the survival rate of the goslings to reach 96%-98%, the average weight to be 94.2-96.2 g, and the health status to be good; the survival rate and average weight of Comparative Example 1, which did not use the modified pearl shell powder but only used the pretreated pearl shell powder, and Comparative Example 2, which directly used the mixture of pearl shell powder and citric acid instead of the modified pearl shell powder, were lower than those of the examples, and some of the goslings appeared to be in poor condition and had decreased food intake. This result shows that the feed of the present application is beneficial to the growth and development of goslings, and at the same time, improves the survival rate of goslings.
