Measures to increase the pass rate of breeder eggs

In the case of chickens at low levels, the prices of chickens for commercial hens are very low, and the market competition is very fierce. It is crucial for breeder farms to survive in the competition, increase the rate of qualified eggs and reduce costs. First, the cause of the low rate of qualified eggs 1. The increase in blood eggs, fecal eggs: poor feed, with unreasonable, disease, poor feeding and management, environmental stress and so on. 2. An egg is too big or too small: As a breeder, it cannot be fed like a commercial broiler, and the nutritional level cannot be as high as that of a commercial broiler. If breeder chickens are reared according to commercial broilers, the opening date will be advanced and the egg production will be too small. Of course, if the rearing and management, and the extremely low level of nutrition, will cause delays in the production period. In addition, environmental stress can also make the egg body too small and the number of eggs to decrease. 3. Egg shell quality and egg shape abnormality: Including sand shell egg, steel shell egg, wrinkle egg, broken egg, soft egg, short round egg, olive egg, etc., the formation reasons include genetic, environmental conditions, feeding and management, species Chicken age, feed, etc. Second, measures to increase the qualified rate of breeder eggs 1. Select good varieties of breeders. According to the market, breeder breeds are selected. Their breeds must meet the body type characteristics of the breed, have good health, no genetic diseases, have good production performance, and have a small coefficient of variation. 2. Select a reasonable design of chicken cages. Usually, a plastic net with a hole and a good elastic pull force is used as a bottom pad for a chicken cage, and a plastic net is used for covering around. This can greatly reduce the rate of broken eggs, and can also provide good ventilation and lighting in the cage. 3. Strengthen disease prevention and treatment. Regular cage decontamination, regular vaccination, observing the mental status and appetite status of the flock at any time, persisting in “early detection, early diagnosis, and early treatment” and insisting on the system of isolation treatment and elimination for affected chickens, which can be large To reduce the degree of disease caused by blood eggs, eggs, and increase the number of eggs. 4. Feed full price ingredients. Since calcium, magnesium and vitamin D are the main nutrients affecting the quality of egg shells, they must meet the needs, and calcium and phosphorus should be kept in suitable proportions; the 13 kinds of amino acids needed for poultry in feeds must be met, energy and protein must be kept at an appropriate level, and Consider the impact of environmental conditions on nutrient demand and feed conversion rates. 5. Strengthen post-production management. As the egg production rate at the end of laying decreases, the egg weight increases, and the eggshell quality decreases. Therefore, the protein and linoleic acid content should be appropriately reduced in the later stage of egg production, and vitamin D should be increased in a proper amount. 6. Control the opening age and the opening weight. Usually can be taken to limit the feeding and adjust the light intensity and the number of hours to achieve adjustment and control of the opening age and opening weight. 7. Create quiet and comfortable feeding environment. Reduce double yellow eggs, no yellow eggs, soft shell eggs. The housing should be kept away from noise, pollution, and good ventilation and lighting. The temperature should be controlled at about 20°C. 8. Increase the number of quail eggs, reduce cracked eggs and reduce the degree of contamination of the eggs.
