The pigeons are the fourth most poultry after chickens, ducks and geese, and China has abundant pigeon breeding industry. In foreign countries, breeding of carrier pigeons and ornamental pigeons is mainly used, and both carrier pigeons and ornamental pigeons are bred in China, but the breeding industry of meat pigeons is the most huge. The meat pigeon has large body size, mild temperament and high reproduction rate, and can adapt to various climatic conditions; the feed is simple, can feed various raw grains of coarse cereals, and is suitable for large-scale cultivation and family cultivation. The related data show that 4500 ten thousand pairs of parent generation breeding pigeons exist in China, 6 hundred million commercial meat pigeons are produced in the year, 8 hundred million pigeon eggs are produced, and the breeding amount accounts for more than 80% of the world. In the current situation of poultry breeding in our country, the chicken industry is relatively developed at present, a plurality of production problems are solved or are being solved, the pigeon breeding industry is relatively lagged behind, a plurality of problems still exist in pigeon breeding and need to be solved, the production technology is lagged behind and single, and scientific research investment is insufficient. Many pigeon diseases seriously damage the health of the meat pigeons, so that the production performance of the meat pigeons is reduced, and then the loss of economy is huge, and the pigeon coccidiosis is one of the most serious diseases damaging the health of the meat pigeons and is also one of the pigeon diseases which are least overlooked in the current pigeon farms. The coccidiosis of the pigeons is parasitic protozoa which is parasitic on epithelial cells of intestinal tracts of the pigeons by various Eimeria coccidiosis, can cause diarrhea, emaciation and slow growth and development of the pigeons, and can cause a large amount of death in severe cases.

In recent decades, experts and scholars at home and abroad invest a great deal of energy and funds for solving the chicken coccidiosis, a plurality of breakthroughs are made on the research of immune prevention and control of the chicken coccidiosis, and a plurality of vaccines for preventing and controlling the chicken coccidiosis are published. At present, researches on pigeon diseases at home and abroad are few, most researches on pigeon diseases are carried out by using common-grade or clean-grade experimental pigeons, and SPF-grade experimental pigeons are not developed yet. At present, the research on the prevention and control of coccidiosis in pigeons is still in the recognition stage, people have insufficient understanding on the coccidian in the pigeons, and once the research on the coccidian in the pigeons needs to be deeply carried out, an experimental pigeon without coccidian needs to be used for carrying out animal experiments. However, most of the common-grade or clean-grade experimental pigeons used at present have complex feeding environments, coccidium is difficult to completely eliminate, and coccidium infection still exists in the experimental pigeons of the grades, so that the requirements of experimental animals for carrying out experiments on the pigeon coccidium animals cannot be met.

Detailed Description

The concept and technical effects of the present invention will be clearly and completely described below in conjunction with the embodiments to fully understand the objects, features and effects of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and those skilled in the art can obtain other embodiments without inventive effort based on the embodiments of the present invention, and all embodiments are within the protection scope of the present invention.

The breeding method of the experimental pigeon without coccidia is mainly based on the life history of coccidia and the unique characteristics of coccidia, namely coccidia self-limitation. The self-limitation of coccidium means that after the host is infected with the coccidium once, if the coccidium is not infected again, the coccidium can not be parasitic in the host for a long time, and the coccidium can be automatically disappeared from the host. Therefore, the pigeon coccidiosis is also a self-limiting disease, the invention fully utilizes the characteristic of coccidium, adopts various coccidium purification methods to purify the breeding pigeons which can carry the coccidium in the common level or the clean level into the coccidium-free breeding pigeons, and enables the breeding pigeons to lay coccidium-free hatching eggs, the coccidium-free hatching eggs are fed to the breeding pigeons, the breeding pigeons which lay the breeding pigeons for self-incubation again and the thoroughly-purified coccidium-free experimental pigeons.

The selected breeding pigeons meet the following standards:

(1) soft and bright appearance, fierce eyesight, sensitive reaction, no abnormal diet, no picky eating and the like.

(2) No ectoparasites and all helminths, such as mites, roundworms, etc., were detected.

(3) Has no pigeon pox, pigeon Newcastle disease, salmonellosis, colibacillosis, etc.

Purification site requirements

And (3) placing the breeding pigeons which meet various health indexes after detection into an animal room for breeding, wherein the pigeons are never bred in the animal room, and no other pigeon farms exist at the periphery. The breeding pigeon breeding cage is a special cage for the breeding pigeons purchased from the market, an egg nest is automatically installed and fixed, and the pigeon cage is disinfected and cleaned by flame before use.

Arranging and treating breeding pigeon

After the breeding pigeons are grabbed into the cage, the breeding pigeons should be fed with water after drinking, stress-resistant medicines, such as doxycycline or ciprofloxacin, are added into the drinking water, and the breeding pigeons are drunk for 1-4 days. Aims at preventing water and soil abuse and preventing other bacterial infections such as paratyphoid, pigeon cholera and the like. The pigeon to be bred is stabilized in a new environment, so that the coccidian can be purified.

Isolated hatching of hatching eggs

Hatching eggs in isolation is an effective method of eradicating coccidial infections. Before hatching eggs in a hatching machine, 0.1 percent iodine solution with the temperature of 37-40 ℃ is used for soaking for 1 minute, so that coccidian oocysts which can be attached to the surfaces of the hatching eggs can be effectively killed. The incubator is used after fumigation for 24h in advance 1 day and air drying naturally. When hatching eggs, the eggs are artificially irradiated for three times, the taken hatching eggs are placed on a light source respectively on the 5 th day, the 10 th day and before hatching, and are irradiated by light, and on the 5 th day, if black spots are seen in the middle of the eggs and spider-web-shaped blood vessel distribution is seen on the sides, the eggs are good fertilized eggs. If the egg is transparent, it is clear egg. If the blood vessels are distributed in the egg but the egg is a thick line, the egg is a dead and sperm egg. And on the 10 th day, if one end of the egg is black and fixed and the air chamber at the other end is obviously increased, the egg is a good germ layer. If the egg is flowing like water or gray black, it is a dead embryo egg. Taking out the clear eggs, the dead clear eggs and the dead embryo eggs in time, continuously hatching the reserved eggs, and manually assisting to remove the shells of the young pigeons which naturally break the shells but cannot naturally break the shells when the young pigeons are hatched to the 17 th day.

Test 1

Comparison of coccidium purifying effect of shuttle medication and experimental pigeon with single medication

In order to prove that the coccidium purifying mode by using the shuttle medicines and the alternately-used medicines in the method can purify the coccidium in the pigeon in a short time and shorten the breeding time of the coccidiless pigeon compared with the single medicine. A contrast experiment of the coccidium purifying effect of the shuttle drug and the experimental pigeon with single drug is developed.

Test protocol:

1. the source of experimental pigeons is as follows: a breeding pigeon farm with a mild infection of a certain coccidia.

2. Grouping experimental pigeons: 20 backup pigeon breeders with similar body weight and age of 5 months are selected. 10000 oocysts of the pigeon coccidia mixed strain sporulation strain are inoculated to each pigeon before the test. Every 5 of the three groups are a shuttle group, a single-use group A and a single-use group B, and an infection non-use group is arranged.

3. The medication method comprises the following steps: the shuttling medicine is prepared by mixing sulfachloropyrazine sodium soluble powder with 300mg/L for 3 days continuously, and the rest period is 1 day. After 5 days, 1mg/L diclazuril soluble powder is mixed for drinking, and the continuous use lasts for 5 days, and the withdrawal period lasts for 1 day. The single medicine A group uses sulfachloropyrazine sodium soluble powder, 300mg/L mixed drinking, continuous use for 3 days, rest period for 1 day, and medicine is used once after 7 days. The single medicine B group uses diclazuril soluble powder, 1mg/L mixed drink, and the medicine is continuously used for 5 days, and the rest period is 1 day. The drug is administered once more after 3 days. The mental state, diet condition and clinical symptoms of each group of pigeons are recorded every day after the test is started, the pigeons in each group are weighed before and after the test to count weight gain indexes, and the ovulation sac conditions are observed and recorded on the 3 rd day, the 7 th day and the 14 th day after the test is finished.

And (3) test results: after the coccidian oocysts are infected, the coccidian excrement which is yellow green, chocolate-colored or water-like and has the symptoms of depression, appetite reduction and emaciation begins to appear after the coccidian oocysts are infected without using a medicine set. The shuttle medicine group, the single medicine group A and the single medicine group B have good mental state, normal diet and no abnormal excrement. On the 3 rd, 7 th and 14 th days after the test, no oocysts were discharged after the shuttle group test, two single-drug group A returned positive on the 7 th day after the test, and coccidia oocysts were still discharged on the 14 th day after the test. The single-dose group B has one returned positive on the 3 rd day after the test is finished, two returned positive on the 7 th day after the test is finished, and coccidian oocysts are still discharged on the 14 th day after the test. The weight gain data before and after the test are shown in table 1 and the ovulatory capsule status is shown in table 2.

TABLE 1 weight gain indexes of groups of drugs used for infection and groups of non-drugs used for infection

TABLE 2 statistics of oocyst removal by drug unit after completion of the experiment

* "-" indicates negative for coccidiosis free; "+" indicates coccidia positive.

The data in Table 1 show that the shuttle drug group, the single drug group A and the single drug group B are superior to the infection drug group in weight gain and feed-meat ratio. The shuttle medicine group is superior to the single medicine group A and the single medicine group B. The data in Table 2 show that none of the shuttling medications returned positive after the medication trials were completed. The single-drug group A and the single-drug group B both have different degrees of return yang.

And (4) test conclusion: in conclusion, the shuttle drug and the single drug can inhibit the coccidian infection to different degrees. The effect of singly using sulfachloropyrazine sodium is slightly better than that of singly using diclazuril, the effect of using two medicines in a shuttling way is better than that of singly using diclazuril, and the anticoccidial effect is still better after the shuttling medicine is used for 14 days. After single medication, the single medication A group and the single medication B group have different degrees of return yang conditions, which shows that the single medication effect is not as long as that of the shuttle medication. Therefore, the method for purifying coccidium by using the shuttle medicine in the breeding method can purify the coccidium in the pigeon in a short time and shorten the breeding time of the coccidium-free pigeon compared with the method by using single medicine, and is more favorable for breeding the coccidium-free experimental pigeon. Moreover, the experimental pigeon cultivated by the cultivation method has high cleanliness.

The embodiments of the present invention have been described in detail, but the present invention is not limited to the embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge of those skilled in the art. Furthermore, the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
