The choice of breeding pigeons When selecting a breeding pigeon, it depends on the production performance of its ancestors, such as the number of eggs per year, egg weight, fertility rate, hatching rate, survival rate of the sub-pigeon, and the weight of the 28-day-old pigeons; The body weight is above the average body weight, the plumage is compact, the hen’s head is delicate, the neck is slender, and the cheekbones of both legs are slender; the communicative pigeon is tall and majestic, with strong and strong legs, and has a strong sexual desire; the pigeons must be timely rectified. If the number of egg nests per year does not reach more than 8 nests, the mother and mother do not get together, the fertilization rate is less than 98%, the quality of the nurtured pigeons is poor, and the nature of the nurses is not strong enough. Loft requirements In the north-to-south direction, a double-row loft-style loft is built. Each column is 23 meters long and uses a 4-story, 8-room metal cage so that each row can breed more than 300 pairs of pigeons. Columns are 4 meters to 5 meters apart. Feeding management Feed preparation pigeons have a habit of picky eaters. For a variety of feeds mixed together, the order of the feeds to eat is: mung beans → peas → wheat → corn → soybeans → rice → sorghum and so on. Therefore, it is best to formulate pellets. , so as not to cause certain nutrient deficiencies caused by picky eaters. At the same time, certain ingredients of feed ingredients should be increased or decreased according to changes in the season and production cycle. When formulating feed, pay attention to the balance of animal proteins, especially essential amino acids. Animal protein is very important for the pigeon's egg production, fertilization rate and hatching rate and the weight of the 28-day-old pigeon. The feeding method was fed 3 times a day, with regular ration. Feeding time is usually taken at 7:30 in the morning, 2:00 at noon, and 6:00 in the evening; the amount of feeding is about 40 grams per pair of pigeons during the non-feeding period; the best feeding period is continuous feeding, if not for feeding pellets, Before feeding, soak the feed with warm water (about 40°C) for 30 minutes, dry it slightly and feed it again, which is good for pigeons' digestion. The preparation and delivery of health sand and the quality and feed intake of health sand directly affect the growth and development of pigeons. In the breeding period, the formulation of health sand: sand 35%, yellow mud 20%, shell powder 15%, salt 5%, lime 2%, poultry multidimensional 2%, gentian 0.5%, gypsum powder 2%, eggs Shell powder 2%, bone meal 2%, charcoal powder 6%, fish meal 5%, licorice 1%, growth hormone 1.5%, oxytetracycline calcium salt 0.6%, yeast tablets 0.4%. Pigeons like to eat fresh, dry health sand. Therefore, it is best to put the health sand one time a day. Daily management and epidemic prevention Daily management to do four look: see the mental state, healthy pigeons lively, excited, sensitive; look at the diet, healthy pigeons eat faster, generally drink water after eating; see the feces color and shape, normal pigeon droppings are gray, yellow brown Or grayish black, shaped like a strip or spiral, with a white uric acid substance attached to the end; see the pigeon care, observe whether the pigeons are trampled, pressed, lost, injured by rodents, etc. Safe and healthy growth. Incubation period management: When the breeding pigeons are hatched, some male and female pigeons often fight for the hatching, thus breaking the eggs, and some species of pigeons linger after eating, thus affecting the development of the embryo and even causing embryonic death. For the former situation, they should be paired again and the nesting eggs should be hatched by the nanny. In the latter case, the pigeons should be returned to the nest for hatching and the light should be obscured. After 3 days to 5 days, the pigeons can be hatched. Avoid this phenomenon. During the hatching process, eggs are easy to win by feces. Therefore, always check them. If there is feces contamination, wipe the stool with a towel soaked in warm water. This can significantly increase the hatching rate and avoid washing with water. Otherwise it is unfavorable to the development of the embryo and even results in the death of the embryo. The pigeon's incubation period is 18 days. During the entire incubation period, it takes 2 shots. The first time is the 5th day of hatching. The main reason is to eliminate the lean egg. The inspection method is simple and effective. If the egg is yellow and translucent, as with no hatchery, then no egg is available; the second shot is the 12th day of hatching. Check the development of the embryo and pick out the dead embryo. Some embryos are not robust enough to develop. When shells are hatched, they are shell-breaking, but they cannot afford their own shells. At this time, artificial midwifery is needed. This is to use needles to stretch the eggs around the hole in parallel to spread it, and then wait for it to mature. After their shelling. If the blood vessel has not completely contracted, the blood vessel cannot be forcibly ruptured. Otherwise, death will occur due to excessive bleeding. With artificial labor, the pigeons are generally safe to hatch. This is an effective measure to increase the hatching rate.
