Are 500 pairs of pigeons suitable for free-range breeding in greenhouses?
What you should say is the pigeon house.

Group pigeon houses are mainly suitable for young pigeons. Generally, there are more single-row bungalows, and old houses can be rebuilt. Because grass is easy to get wet and moldy, pigeons are easy to get moldy and sick, so don't use grass tail as a pigeon house. It is best to adopt brick-wood structure or civil structure for the new pigeon house.

Single row bungalows, each with a width of 5-5.2m and a length of 12- 18m. The eaves are 2.5 meters high, and the house is divided into 4-6 small rooms with nets or bamboo, and each room can raise 50 pairs of young pigeons. The front and rear walls of each pigeon house should be opened with front and rear windows, and the front window can be lower than the ground. The window room area is 1.2- 1.4 square meters, and the front window is off the ground 1- 1.2 meters, which is convenient for the summer climate wind to enter the house. The rear window is generally off the ground 1.6- 1.8 meters to avoid the invasion of the north wind in winter. At the same time, under the back wall, about 20 cm from the ground, several floor-to-ceiling windows (40 cm× 60 cm or 40 cm× 40 cm in size) should be opened for ventilation in summer and wet weather. It is best to use big red brick or concrete on the ground. The ground is required to be flat and clean, and there is no water accumulation in wet weather. The ground is 30-40 cm higher than that of the sports ground, which can keep the habitat dry. In addition, in the front of each pigeon house, there should be a sports ground, which is about the same length and width as the pigeon house and about 2.5-2.8 meters high. It can be surrounded by steel, logs or cement columns and galvanized lead wire mesh, and the top is covered with nylon mesh. In order to facilitate operation and management, the gate position of the sports ground should be consistent with the pigeon house.

See what kind of pigeon you are. If you are a meat pigeon, I still have some suggestions:

First, pigeon farm preparation:

Pigeons are afraid of humidity, sweltering heat and animal injury. In order to facilitate management and epidemic prevention, pigeon farms with conditions should be selected in dry, well-ventilated, well-lit, convenient transportation, pollution-free and noise-free places. There are many types of pigeon houses, including double cages, single cages, group cages, open sheds, etc., preferably facing south or southeast.

Pigeon farms without conditions can be transformed by using old factories and warehouses according to local conditions. After successful breeding, there will be an economic base for further development.

B, pigeon coop preparation:

Pigeons are sold in the pigeon coop market. For small farmers' pigeon farms, they can buy galvanized nets to make their own. The self-made pigeon coop is 180 cm long, 50 cm high and 60 cm deep. It is divided into three small rooms with nets in the middle, and each room can support 1 pair. The spacing of the bottom net is 1 cm, and the spacing of the lower half of the back net, the partition net and the side net is 1.5 cm. The spacing between the front screen and the top screen can be larger.

Pigeons have troughs, water cups, eggs, sand cups and so on. , can be purchased in sets, can also be made of cans and bottles.

C, pigeon breeding technology preparation:

Improving the reproductive rate, survival rate and first-class product rate of meat pigeons is the key to ensure the success of pigeon breeding. Whether it is external training or internal training, it is necessary to solve the talent problem of pigeon breeding technology in advance. If it is internal training, it is necessary to arrange personnel or go to a regular pigeon breeding farm for training. If you don't have the conditions, you need to buy a lot of professional pigeon breeding books, newspapers and magazines for self-study, or you can go to our online school "Pigeon Knowledge Lecture" and electronic publication "Pigeon Breeding Technology"

D, preparation of pigeon beverage:

Pigeons have no gallbladder, mainly plant feed, and like to eat granular substances, such as corn, rice, wheat and beans. This requires the preparation of materials according to local crop resources. However, the variety and quality of raw grain are inconsistent, the feed stability is poor, pigeons are picky eaters, and the nutritional components are often incomplete and unreasonable, which affects the production of meat pigeons. Therefore, conditional pigeon farms should have the idea of buying pellet machines and making their own pellet feed for meat pigeons. You can also buy professional pigeon feed in the market.

E, pigeon epidemic prevention preparation:

Meat pigeons have strong disease resistance, but with the rapid development of pigeon breeding industry, pigeons are introduced and traded frequently, and the incidence of diseases is increasing day by day. Antibacterials, disinfectants, anthelmintics and other drugs that need to be preserved.

F, pigeon introduction preparation

Before introduction, we should fully understand the source of breeding pigeons, master the basic knowledge of breeding pigeons, buy them from qualified seedling business units, adhere to the principles of quality comparison, price comparison and service comparison, and adhere to the principle of purchasing nearby to ensure the quality, price and structure of breeding pigeons. Newly-built pigeon breeding farms should be gradually introduced, and the scale and structure of pigeon breeding should be gradually expanded and optimized.

Third, the basic knowledge of raising and managing meat pigeons

First, carrier pigeon breeding management knowledge

Pigeons from hatching to 28 days old are collectively called squabs (squabs from birth to 10 days old and 10 days old to 20 days old in some areas).

Two hours after the squab came out of the shell, the mother pigeon began to blow the squab with her beak, and two hours later, the squab began to feed the pigeon with milk. At this time, young pigeons are small and weak, and it is easy to die. We must strengthen management. First, observe carefully and pay attention to avoid being trampled to death or frozen to death by breeding pigeons. If the young pigeon can't eat pigeon milk for 5-6 hours, it is necessary to find out the reason in time (if necessary, feed the young pigeon with artificial pigeon milk). It is found that when parents are not breastfeeding, they can find breeding pigeons for foster care at the same time, and some parents can avoid feeding single pigeons, thus improving production capacity.

After 3 ~ 4 days of age, the pigeon's eyes slowly open, its body gradually becomes stronger, its feathers begin to grow, its food intake gradually increases, and its digestive ability is enhanced. At this time, homing pigeons should often feed their young pigeons, sometimes as many as ten times a day, so the amount of feed supplied to homing pigeons should be sufficient and the nutrition should meet the needs. At this time, the amount of feces discharged by young pigeons increases, which is easy to pollute the nest. Change bedding and forage in time every day to avoid diseases.

10 day old, young pigeons grow many new feathers and can walk by themselves. The heat preservation time of young pigeons was shortened by parents, and the food fed by parents changed from pigeon milk to semi-pellet feed. A few young pigeons have not fully adapted, and often have indigestion and crop infection. In this case, you should take some yeast tablets or stomach medicine in time to help digestion.

Pigeons 15 days old have basically the same feathers and can move freely. You can grab the nest and spread a piece of 20 cm× 20 cm cloth in the cage to let it adapt slowly without spraining its foot. At this time, the feed given by parents is granular, which is the same as the feed they eat, and most parents have started laying eggs again, so they have no intention of feeding the young pigeons, so they should be artificially fed during this period.

After 20 days of age, the squab is full of feathers and can move in the cage, but it can't completely peck by itself. You still have to rely on the pigeons, but you can take the initiative to beg for food from the pigeons. At this time, the mother pigeon will force it to eat independently. At this time, it is necessary to strengthen management and increase the supply of high-protein feed to meet the needs of young pigeons. Pigeons can reach 500 ~ 750g when they are 25 ~ 28 days old, and they can be sold (young pigeons at this time are called young pigeons).

B, pigeon breeding management knowledge

From leaving the nest at the age of 28 to transferring, it is best to achieve "three invariants" where conditions permit: in-situ feeding, original breeder feeding and keeping the original feed unchanged, which can promote the normal growth and development of young pigeons. Pigeons under 2 months old are difficult to raise from parent pigeon to independent life, so it is necessary to strengthen feeding management, pay attention to heat preservation and ventilation, strengthen the supply of sanitary sand and feed nutrition, and increase the disease resistance of the machine to make it grow and develop normally. At this time, it is necessary to do "three inspections": "three inspections" are to look at the dynamics, the amount of food, and the feces; The "three checks" are to check whether we have eaten feed, whether we are overcrowded, and whether we have been bitten. Those who can't eat feed can be fed separately, those who are bitten and injured can be cared for in time, and those who are aggressive can be fed separately. If it is crowded, it can be raised in groups. Pigeons begin to molt at the age of 2 months, so protein feed should be appropriately added in the feed to promote feather renewal. Add 5% hemp seed to feed, andrographis paniculata or gentian to health sand, and add a small amount of antibiotics to drinking water in a planned way to prevent respiratory diseases and paratyphoid fever. In the meantime, special attention should be paid to the hygiene of cages and utensils, and they should be cleaned and disinfected on time. At 3 ~ 4 months, the secondary sexual characteristics began to appear, and the activity ability became stronger and stronger. At this time, it is necessary to eliminate the fittest, raise males and females separately, or forcibly pair them in cages to exterminate homing pigeons and ensure their normal growth and development.

Pigeons gradually began to pair at the age of 5 months, and became sexually mature at the age of 6 months. Most of the main wing feathers of pigeons have been replaced to the last 1, which has basically entered the pigeon breeding period.

C, pigeon management knowledge

1, get ready before laying eggs:

Spawning began 8 ~ 10 days after mating. At this time, if conditions permit, it is necessary to cage (or move to a pigeon house with an egg nest). The egg nest should be prepared and covered with 1 layer of linen to avoid breaking the eggs. It is necessary to check whether there are holes in the cage to prevent the interference of cats, dogs, snakes and rats or the invasion of ventilation and leakage, causing undue losses.

2. Do a good job in the management from spawning to hatching;

(1) After laying eggs, check whether there are abnormal eggs and broken eggs in time, and take them out in time. For newborn pigeons, always observe whether the egg nest is fixed and whether the two eggs are concentrated in the center and bottom of the egg nest. (2) Observe whether the new spouses are harmonious, whether they often jump around and peck at each other, resulting in broken eggs. For large pigeons, special attention should be paid to prevent them from pressing eggs, and more importantly, pigeons with malnutrition or bad eating habits should be prevented from pecking eggs. ③ Take pictures of eggs on time, deal with bad people in time, and take out eggs without sperm, dead sperm and dead embryos in time to prevent eggs from stinking and affecting the health of normal eggs and pigeons. If unfertilized eggs and dead embryos are found, we should find out the reasons and improve the management system.

3. Combine eggs at the same time and hatch in pairs;

If there are 65,438+0 eggs in the nest or 65,438+0 eggs left after two exposures, the eggs at the same time should be hatched in pairs to improve productivity.

4, the nest should be kept warm and clean:

Prepare the double egg nest. Pigeons should be kept warm after birth. Change linen (hay) frequently, wash the feces in the egg nest frequently, and keep it clean and hygienic. When the young pigeon 12 days old, it should be put into an egg nest for standby, because at this time, the breeding pigeon begins to lay the second nest of eggs, and the second nest of eggs will be produced around 15 days. Breeding pigeons bear the dual tasks of breastfeeding and hatching. At this stage, it is necessary to carefully manage feeding, increase feed nutrition and increase feeding times to ensure the completion of the dual tasks of breeding pigeons.

5, do a good job of registration records:

Keep a record of pigeon production at any time to provide an important digital basis for future feeding management.

I wish you a prosperous business and rich financial resources!
