First, the choice of breeding pigeons: When choosing to keep the breeding pigeons, we must look at the ancestors in a variety of production performance, such as the number of eggs per year, egg weight, fertilization rate, hatching rate, survival rate of young birds and 28 days old pigeons Weight; individual choice should pay attention to a body weight above the average weight, tight plumage, the hen's head is delicate, the neck is slender, the legs are slightly slender; the covenant is tall and majestic, the legs are strong, the sexual pigeons are strong; The production of pigeons must be carried out in a timely manner in order to rectify the pigeons. When the number of eggs per year does not reach 8 çªœ or more, the male and female do not know, the fertilization rate is less than 98%, the quality of the nursery pigeons is poor, and the nursery traits are not strong enough. Time out. Second, the requirements of the loft: According to the north to south direction, built a double row of factory-style lofts, each column about 23 meters, using four-storey 8-room metal cage, so that each breed can breed more than 300 pairs of pigeons. Columns are 4-5 meters apart. Third, feeding and management: 1. Preparation of feed: pigeons have a picky habit, for a variety of feed mixed with the diet, the order of eating feed: mung beans â†’ peas â†’ wheat â†’ corn â†’ soybeans â†’ rice â†’ sorghum, etc. Therefore, it is best to be formulated into pellets to cause some nutrient deficiencies in rabbits. At the same time, certain ingredients of feed ingredients should be increased or decreased according to changes in the season and production cycle. Summer is hot, add mung beans to heat and reduce heat; in winter, cold, increase hemp seed to increase the energy value of feed; add rapeseed during the moulting period to shorten the moulting time. 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 as well as the weight of 28-day old vets. 2. Feeding method: 3 times a day, regular ration. Feeding time is usually 7:30 in the morning, 12:00 in the afternoon, 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 you do not feed pellets, soak the feed with warm water (about 40Â°C) for 30 minutes before feeding. Dry it slightly and feed it again. It is good for pigeons to digest. 3. Preparation and input of health sand: The quality and feed intake of health sand directly affect the growth and reproduction of pigeons. In the breeding period, the formulation of health sand (%): Hesha 35, Huangni 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, 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. 4. Day-to-day management and prevention of epidemics: (1) Day-to-day management to achieve a four-fold look: see the state of mind, healthy pigeons lively and excited, sensitive; look at the diet, healthy pigeons eat faster, generally drink water after eating; see the color of feces and In the shape, the normal pigeon droppings are gray, yellowish brown or grayish black, shaped into strips or spirals, with white uric acid substances attached to the end; watching the pigeons' nursing condition, observe whether the pigeons are stepped on, pressed, or not. Lost, be harmed by rats, etc. to ensure safe and healthy growth of pigeons. (2) Incubation period management: When the breeding pigeons are hatched, some of the male and female pigeons often struggle to compete for hatching, thus breaking the eggs, and some of the breeding pigeons will linger after eating, thus affecting the development of the embryo and even causing embryonic death. . The former situation should be re-matched and the nesting eggs should be hatched by the nanny. In the latter case, the pigeons should be returned to the nest in time for hatching, and the light should be obscured. After 3-5 days, it can be avoided. this phenomenon. During hatching, eggs are easily contaminated with faeces. Therefore, they should be checked frequently. If feces are contaminated, gently wipe the excrement with a towel soaked in warm water. Song can obviously improve hatching and avoid using 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, and no hatching, then there is no egg; the second egg 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 are unable to shell themselves. At this time, artificial midwifery is needed. This is to use needles to stretch the eggs around the hole in parallel to cross them, and then wait for it to mature. Shell yourself. If the blood vessel is not completely contracted, the blood vessel cannot be forcibly ruptured. Otherwise, it will cause death due to excessive bleeding. With artificial midwifery, the pigeons can generally be safely shelled, which is an effective measure to increase the hatching rate. (3) Management during the rearing period: For individual first-born pigeons that do not feed pigeons, training should be given. That is, the mouth of the pigeon is carefully inserted into the mouth of the pigeon. After many repetitions, the pigeons are usually nurtured or used. The nanny pigeons are nurtured to promote the survival of the young pigeons. Change the position of the pigeons: When some of the pigeons are breastfeeding, they always feed the first one on the outside of the nest, which results in uneven development of the two pigeons. It also causes the overfeeding of 1 to produce a smashed food and indigestion. . Therefore, the position of the two pigeons should be changed frequently so that they grow evenly to improve the quality of the pigeons. For a nest with only 1 egg or 1 pigeon, two nests are combined or tripled according to their age. This reduces the burden on the breeding pigeons and allows them to lay eggs in advance to improve the production of the breeding pigeons. effectiveness. Generally, 15-18 days after the puck is hatched, the pro-pigeon can lay a nest of eggs. If the pigeons are not left in time, they will affect the egg laying and hatching. Under the nest time, in general, the summer 12 days is appropriate, winter 15 days is appropriate. The time between the separation of the pigeon and the pigeon was generally 21 days or 28 days for the commodity pigeon, and 28 days or 30 days for the breeding pigeon.
