Design of Pigeon Greenhouse

When designing the pigeon breeding greenhouse, we should not only consider the fresh air, sufficient sunshine, dry ground, warm in winter and cool in summer, clean and quiet, but also make it better to sit north to south, brick structure, east door and convenient operation and management. but also to be able to prevent animal damage. Pigeon breeding greenhouses come in a variety of forms, including group and cage pigeon houses.

Group pigeon house

Group-raised pigeon houses are mainly suitable for young pigeons. Generally speaking, there are many single-row bungalows, which can be rebuilt by using old houses. As grasses are susceptible to damp and moldy, pigeons are easily attacked by molds, so do not use grass tails as pigeon houses. It is best to use brick structure or civil structure in the new pigeon house.

The single-row bungalow is 5.2 meters wide and 12 meters long. The eaves are 2.5 meters high, and the house is divided into 6 cubicles with net or bamboo, each of which can keep 50 pairs of squab. The front and rear windows should be opened on the front and rear walls of each pigeon house, the front window can be lower from the ground, the area of the window room is 1.2 square meters, and the front window is 1.2 meters away from the ground, so as to facilitate the summer weather wind to enter the house; the rear window is generally 1.6 meters 1.8 meters away from the ground to avoid the attack of winter north wind. At the same time, under the back wall, about 20 cm from the ground, several floor windows (40 cm × 60 cm or 40 cm × 40 cm) should be opened for ventilation in summer and humid weather. The floor of the house should be made of large red brick or concrete, which should be smooth and clean, and no water should be poured out in wet weather. The ground is 30cm higher than the ground of the playground, which keeps the habitat dry. In addition, on the sunny side of each pigeon house, a playground should be set up, which is similar in length and width to that of the pigeon house, with a height of 2.5ft 2.8 meters, which can be surrounded by steel, log or cement columns and galvanized lead wire mesh, and the top is covered with nylon mesh. For ease of operation and management, the position of the door of the playground should be the same as that of the pigeon house.

Cage pigeon house

The so-called cage breeding is to keep the matching breeding pigeons on the ground, so that they can live, eat and drink separately. The utility model has the advantages of simple structure, low cost, convenient management, stability of pigeon flock, high utilization rate of pigeon house, etc. There are two forms of this pigeon house.

1. Double-row pigeon house

The roof truss is often herringbone, 2.5 meters high in the north and 2.8 meters in the south. If the roof is covered with fiberglass or asbestos tiles, attention should be paid to strengthening and plugging leaks to prevent tornadoes, typhoons and storms. The depth of the pigeon house is 2.2 meters, and the central part of the pigeon house needs to have an operation lane 0.8 mi 0.9 m wide, with drains on all sides. Pigeon cages stand opposite each other, there can be 3-story or 4-story cages, it is better to hang canopy from the top to the ground, the tarp can be put down to keep warm in winter, and the tarp can be rolled up in other seasons for ventilation and light transmission.

The periphery and upper layer of the cage are barbed wire, a wooden door or bamboo is arranged on one side of the operation channel, and the food trough and health sand cup are hung on the cage door to facilitate feeding and observation. To facilitate water supply and flushing, a long flume should be installed on the outside of the cage. The cage has a width of 60 cm, a depth of 60 cm and a height of 55 cm. There is no gap between the upper, middle and lower cages, and the bottom of the lowest layer is about 20m / 50cm from the ground. If the length of each row of cages is 3 storeys, it is generally 18m ~ 21m.

2. Single-row pigeon house

The structure of single-row pigeon house is similar to that of double-row pigeon house. The single-row pigeon house has only a pigeon cage on the sunny side, with brick walls on the shade side and several windows on the wall, which is different from the double-row pigeon house. The advantage of single-row pigeon house is to sit north and face south, so it has plenty of sunshine, good ventilation and warm in winter. However, its deficiency is that the amount of feeding per unit area is half less than that of the two-row type and covers more area.

Management of Pigeon Culture in greenhouse

1, feed preparation: pigeons have the habit of picky food, for a variety of feed mixed diet, the order of eating feed is: mung bean → pea → wheat → corn → soybean → rice → sorghum, etc., therefore, it is best to match into granular materials, so as not to be picky food caused by some nutritional deficiencies. At the same time, some components of feed raw materials should be increased or decreased according to the changes of season and production cycle. It is hot in summer, add mung beans to clear the heat and reduce the fire. Cold winter, increase hemp kernel to improve the energy value of feed. Rapeseed was added during molting to shorten the molting time. When preparing feed, attention should be paid to the balance of animal proteins, especially essential amino acids. Animal protein is very important for egg production, fertilization rate and hatching rate of pigeons as well as the weight of 28-day-old pigeons.

2. Feeding method: three times a day, fixed time and quantity. The feeding time should be 7:30 in the morning, 2:00 in the afternoon and 6:00 in the evening. The feeding amount is about 40 grams per pair of pigeons during the non-feeding period. During the feeding period, it is best to keep feeding, if not feeding grains, before feeding, soak the feed in warm water (about 40 ℃) for 30 minutes, dry and then feed, which is beneficial to the digestion of squab.

3. Preparation and delivery of health care sand: the quality and feed intake of health care sand directly affect the growth, development and reproduction of pigeons. During the breeding period, the formula of health sand (%) was as follows: River sand 35, yellow mud 20, shell powder 15, salt 5, lime 2, poultry multidimensional 2, gentian 0.5, gypsum powder 2, eggshell powder 2, bone meal 2, charcoal powder 6, fish meal 5, licorice 1, auxin 1.5, oxytetracycline calcium salt 0.6, yeast slice 0.4. Pigeons like to eat fresh, dry health care sand, so it is best to put health care sand once a day.

Daily Management and Disease Control of Pigeon

1. Four aspects of daily management: look at mental state, healthy pigeons are lively, excited and sensitive. Depending on the diet, healthy pigeons eat faster and generally drink water after eating. Look at the color and shape of feces, normal pigeon feces are gray, yellowish brown or grayish black, shaped into strips or spirals, with white uric acid attached at the end. Look at the nursing care of pigeons, and observe whether pigeons are trampled, pressed, lost, harmed by rats, etc., to ensure the safe and healthy growth of pigeons.

2. Management of incubation period

When breeding pigeons hatch, some male and female pigeons often fight for hatching, thus trampling on the eggs, while some breeding pigeons linger after they come out to eat, thus affecting the development of embryos and even causing embryo death. The former case should be re-paired and the nest eggs should be hatched by nanny pigeons. In the latter case, the pigeon should be rushed back to the nest in time to hatch, and its light should be dimmed. After 3 to 5 days, this phenomenon can be avoided. Breeding eggs are easy to be soiled by feces in the process of hatching, so check them frequently. If there is fecal contamination, gently wipe the feces with towels soaked in warm water, which can obviously improve the hatching rate and avoid washing them with water. Otherwise, it is harmful to the development of embryos and even causes the death of embryos.

The incubation period of the king pigeon is 18 days, and the eggs should be treated twice during the whole incubation period, and the first time is the fifth day after hatching. the main purpose is to remove the azoospermic eggs, the examination method is simple and effective, that is, the eggs are transparent to the light, and if the eggs are yellowed and bright, it is the same as those that have not hatched. For the second time, the egg was hatched on the 12th day, the development of the embryo was checked and the dead embryo was picked out. The development of some embryos is not strong enough, although the shell has been broken, but unable to shell on its own, at this time, the need for artificial midwifery, that is, the needle along the pecking hole along the egg parallel to expand it, and then wait for it to mature after the shell itself. If the blood vessels have not completely contracted, you can not force the blood vessels to break, otherwise, it will cause death due to excessive bleeding. Through artificial midwifery, pigeons can generally come out of their shells safely, which is an effective measure to improve the hatching rate.

3. Management of the feeding period

For individual newborn pigeons who will not feed squab, it is necessary to give training, that is, carefully insert the mouth of squab into the mouth of parent pigeon, after repeated many times, parent pigeon will generally be nurtured, or nursed by babysitter pigeon to ensure the survival of pigeon. Change the position of squab: when some parent pigeons are breastfeeding, they always feed one outside the nest first, resulting in uneven development of two squab and overfed crop, resulting in indigestion. Therefore, the positions of the two squab pigeons should be changed frequently to make them grow evenly so as to improve the quality of squab. For a nest with only one egg or one squab, the two nests should be merged or three-in-one according to their recent age, so as to reduce the burden of breeding pigeons, make them lay eggs ahead of time, and improve the production efficiency of breeding pigeons.
