The selected breeding pigeons first started with the ancestors and needed one year to observe and record. They selected breeding pigeons with strong disease resistance, high reproduction rate, and wide adaptability. The selected pigeons were from the ancestors. Began to be incorporated into the file management, pedigree sound, wearing a ring number. Hybrids of selected races, purification and rejuvenation, double-optimal recombination, and promotion of genetic transformation are used. After three generations, better breeding pigeons will be bred. However, a pigeon is a sentimental bird that must form a companion and reproduce in an environment where the male and female love each other. This process requires an optimized combination, which is also referred to as pairing. Male-female pairing requires certain skills.
(I) Selected breeding pigeons and management from excellent
Breeding of the breeding pigeons, the general breeding performance can not achieve more than 18 each year, there is no leave to leave the conditions of the offspring. When the selected pigeons left their parents at the age of 35 days, they were raised in cages and divided into groups. They usually raised 3 to 4 eggs per cage, and at this time, the weight was less than 550 grams. The lofts and cages in front of the cage need to be disinfected once in advance. The cage was fed 3 to 4 times a day for 15 days, and 2 times a day after 15 days. When breeding, the breeding pigeons are prevented from being too fat and too thin. Too much fat will affect the breeding performance after pairing. There will be bad semen in the cocks, less sperm or more deformed sperm, and less eggs produced by the female pigeons, or even eggs. Too thin to cause malnutrition, affect the formation of sperm and eggs, and there is no more fertilized eggs, so the supply of feed should be guaranteed quality and quantity. Each pair of breeder diets 70-90 grams, can not exceed 100 grams. Keep good air conditions in the pigeon lofts, clean the toilets in time, clear the pigeon droppings, clean the cups, eat nests, and create a comfortable and quiet environment.
(B) The male and female pigeons were reared in pigeons
For 100 to 180 days, the male and female pigeons must be kept in separate rows for the "free-range period" to exercise and enhance immunity. General pigeons grow into estrus after 4 months of age. Pigeon early mating, sexual organs and the body is not mature, affecting breeding, the best breeding period shortened, leading to premature aging of pigeons. Therefore, when the pigeons reach the age of 4 months, they are divided into two groups according to their gender. They are kept in different lofts. Pigs of the SAMe sex should be kept in separate columns. Each column has 50 to 60 eggs. Put more, because the cocks will be chasing each other after sexual maturity. Too much density will hurt the pigeon body. The species and age of same-sex pigeons kept in the same column should also be the same or similar to prevent pigeons from bullying and causing disability.
(c) Matching pigeons reach 6 months of age, and the sexual organs and various functions of the body are sound and can be paired and reproduced at this time. It takes about 10 days for the male and female pigeons to produce feelings to lay eggs. Pigeon pairing technology: At present, the majority of farmers use natural matching, which can easily result in close relatives pairing. The two males compete for females and cause strangulation and bruises; differences in body shape, weight, and breed can cause germplasm degradation. It is best to use artificial matching, according to the ring number, optimization, combination, distant relatives, body weight, body shape, similar age, male and female matching cage. After pairing, there are a few disputes over nests and fights. They should be deployed in time to live in harmony. In addition, the breeding pigeons that are problematic in terms of frigidity and reproductive organs should not be laid after half a month of deployment and should be eliminated.
Breeding requires the introduction of quality pigeons from afar or abroad year by year, and then crossbreeding with the breeding pigeons of their own choosing. The breeding pigeons selected after 3 generations will return to their ancestors. The breeding pigeons can be renamed for convenience. Production, promotion.
