Breeding of yellow chicken breeders

First, breeders choose to stay in the yellow chicken, chicken cocks must be ruddy, especially cocks, cocks must be erect, hypertrophied, ruddy. Eliminating chickens with incomplete growth of feathers, lack of tail feathers, emaciation, lack of energy, and long-lasting variegated feathers that exceed the requirements of the variety make the feather color basically neat and consistent. In addition, the shape and size of the remaining chickens should be basically the same, with fine feet and yellow color. The belly of the hens should be long. The distance between the keel and the pubis must accommodate more than 3 fingers. The distance between the two pubic bones must accommodate the next. Half finger above. The number of selected cocks is 13% for hens, and the ratio of males to females is 1:9 to 11. In general, 2% more roosters are kept alone to prepare for the future death of the roosters or replacement of the roosters. The ratio of caged roosters to hens is 1:23 to 36. Second, the feeding principle Chickens 5% production should be fed when the egg production season; summer can increase the level of dietary nutrition or increase the amount of feeding, the winter is the opposite; daily feeding must be regular, quantitative, less feed in the morning, After 3 pm, feed more to maintain acceptable egg weight and egg shell quality; do not easily change the feed, so as not to reduce the rate of egg production caused by chickens. 3. After artificial breeder chickens are put into production, they will be lighted for 1 hour every week for the first few weeks until they reach 14 hours of light. In the event of insufficient lighting during the day, use lights to supplement the light. Every day during the production of eggs should reach 16 hours of light. According to the duration of the daylight hours, the time for artificial lighting is increased every day. Normally, the lights are turned on before dusk and the lights are turned off around 9:30 in the evening. In the winter, the sunshine is short. After the night is brightened, you can turn on the lights at around 5 in the morning and turn off the lights after dawn. Fourth, timely quail eggs from 10 to 15 o'clock is the most time for chickens to lay eggs, flat-raised chicken coops for 2 hours to pick up eggs once, sooner or later to increase each time. Dirty eggs should be promptly wiped with a dry cloth or bamboo, and stored in the storage after disinfection. The eggs hatched for 3 to 5 days have the highest hatching rate, and the longer the storage time, the lower the hatching rate. V. Eliminating inferior breeding chickens In order to improve the breeding efficiency of breeding chickens, it is necessary to gradually eliminate inferior breeding chickens during the production period so as to reduce feed wastage. The object of elimination was: 1 cock with negative sexual activity (coronal violet and atrophy, lack of energy, no climbing behavior, low semen volume and low fertilization rate of egg); 2 sick chickens and hens with hard belly; 3 feathers shining and not being caught Signs of cock tramping, cloacal small and dry, narrow spacing of the two pubic bones, foot skin color does not fade, the light does not eat the material of the hens lay eggs; 4 late egg production, will not produce excessive fat hens; 5 some chicken grab nest Continuously, but rarely produce eggs, should be eliminated in time.
