Pheasant Breeding Technique - Artificial Hatching
1. Egg choices Chicken eggs are olive, dark brown, light brown, gray and blue. The eggshell thickness is 0.25-0.28 mm, the longitudinal diameter is 4.37 cm, the average diameter is 3.43 cm, and the egg shape index is 1.27. The average egg weight: real estate pheasant 25-30 grams, the United States colorful pheasant 29-32 grams. Incubation eggs must be of a moderate size, egg shape is normal, and the eggshell color conforms to the standards of the species. Egg weight is generally appropriate for 26-30 grams, less than 23 grams and greater than 31 grams, and is not suitable for seeding. Other methods of selecting eggs for pheasants are the same as for chickens.
2. The hatching time of the pheasant chicken hatching time is 23-24 days. When the hatching is normal, the oyster shells begin at the end of the 22nd day, individual shells are hatched, hatched for 23 days and a half, and hatchers are cleaned out at the end of the 24th day. 3. The temperature and humidity of the pheasant chicken hatching temperature and humidity are different from those of chickens and other rare birds. The principle of adopting a variable temperature incubation method and high humidity, low humidity, high humidity, and high humidity before hatching is shown in Table 2-1. 4. Cold eggs start from the seventh day after hatching. If the temperature is high in the summer, cool eggs should be served 1-2 times a day for about 10 minutes each time. 5. Inspection and analysis of hatching effects Chicken eggs hatched in artificial rearing have no more than 5% to 6% of headless eggs and 2% to 3% of dead embryo eggs. If the rate of dead embryos is too high, most of them are due to the storage of eggs. Well, the incubation temperature is too high or too low. Excessive egg-lessness is due to the improper proportion of male and female pheasants, the prevalence of pheasants, and the lack of male fertility or ability to ejaculate. In the second photo, dead embryonic eggs should not exceed 2% -3%, too many dead embryo eggs are often poor breeding of pheasants, embryonic nutrition and incubation temperature is not suitable, due to poor ventilation, embryo transfer after hatching late embryonic The rate is 6%-7%. If this value is exceeded, the hatching conditions in the middle and late periods may be poor. The nutritional requirements of pheasants Because of the different production purposes of pheasants, different growth and development periods and breeding seasons require different requirements for nutrition.
