First, excellent varieties. To breed high-yielding breeders. In the first 3 months of the first paired breeding, we will phase out the late-maturing species that are 8 months old and cannot be paired, and the small birds that weigh less than 0.5 kg. Observe and record the egg laying and hatching conditions. Eliminate continuous eggs, misshapen eggs, or dead pigeons that hatched in hatching; 25 days old pigeons weighing more than 650 grams of all seed. Second, scientific ingredients. The formula for the diet with the young pigeons is: 35-40% of legume feed, 60-65% of energy feed, feed 4 times a day, 2 times in the morning and afternoon; the diet formula for fattening pigeons is: legume feed 25-30 %, 70-75% of energy feed, fed twice a day, each feeding 40 grams. In addition, pigeons are provided daily with adequate health sand and clean drinking water to allow them to feed freely. This is especially important for the production of breast-feeding pigeons and must not be interrupted. Third, and eggs hatch. During hatching, eggs were taken on the 5th and 10th days respectively. The first time the egg was laid, the clear, avascular, "less sperm" and the flattened "dead egg" in the egg were discarded. The second time, the eggs were mainly cut out of embryos. Then the remaining eggs are hatched in every 2-3 eggs and in other cages with the same incubation period. Each pair of breeding pigeons can hatch 3 eggs at a time, so that some of the breeding pigeons can be released from hatching. In about 10 days, eggs can be recovered. Fourth, keep nest. With good management conditions and discontinuous feeding, 1 pair of breeding pigeons can feed 3 pigeons. Only one pigeon is hatched in a nest, or only one pair of pigeons died in the middle, or the pigeons hatched from 13 to 15 days after the first time the eggs were replanted but not fed, can be merged into Other single- or two-daughter nests of the same or similar age and similar size. After breeding, the young breeder can breed eggs more than 10 days in advance, and the egg production rate is increased by 50%. Fifth, the pigeons are nursing. Early artificial feeding of pigeons will enable the relatives to lay eggs 20 days in advance. Pigeon food formula: 1 to 5 days of age, skim milk powder 40 to 50%, 55-60% of chicken feed, poultry minerals, vitamin additives and antibiotics 1-2%, add 5 times water after mixing Into a milky paste; 6 to 10 days old, skim milk powder 25%, chick feed 75%, 1-2% of the above additives, mix well and add 6 times water to make a paste, use a syringe to connect the hose through the esophagus into the milk Pigeon capsule. 1 day of age 4-5 times a day, each 5-7 ml, 5 ml per day from the 2nd day of age, up to 60 ml per 10 days of age; after 11 days of age can be used formula: corn 40%, wheat 20%, pea 20%, milk powder 5%, yeast powder 5%, and added lysine, vitamins, salt and minerals. First use boiling water to adjust the material (material to water ratio of 1:2-3) into a paste, fed two or three times a day. Sixth, artificial pairing. The method is: After the male-female identification, the pair of pigeons are purposely selected and placed in a special pigeon cage, one cage is placed on one pair, and two pigeons are temporarily separated by a mesh partition in the middle of the cage, and the normal water supply is provided. After the two pigeons get close to each other, they move out of the net to allow them to be bred. Seven breeder cages.
