How many eggs can an average farmed laying hen lay in a day? How to raise a high yield? What are the breeding techniques?

Laying hens refer to chickens raised specifically to lay eggs to supply eggs. unlike meat chickens, eggs are the main source of income for laying hens. So how many eggs can an average farmed layer lay in a day? How to raise a high yield? What are the breeding techniques?

How many eggs can an average farmed laying hen lay in a day?

Raising laying hens, generally about 500 days a cycle, or begin to eliminate or enter molting, the number of eggs in about 300.

1. The laying cycle of laying hens has a certain relationship with feeding and management. in normal feeding and management, brown shell laying hens generally see eggs in 150 days (about 130 days for white shell laying hens) and reach laying peak in about 200 days (about 180 days for white shell laying hens). The laying peak can last about 200 days, and the laying rate decreases slowly. When the feeding input is the same as the egg production income, it can be eliminated or forced molting when it is unprofitable. The whole production cycle is about 500 days.

two。 The number of eggs laid in a production cycle of laying hens is related to the laying hens breeds. the superior breeds produce more eggs, while the local hybrid breeds produce fewer eggs. At the same time, it is closely related to feeding management, disease and so on, and sick laying hens even have no feeding value.

How can laying hens be raised with high yield? What are the breeding techniques?

1. Chicken farming saves materials; the yolk and egg whites of eggs are formed during the day, while eggshells are formed in the afternoon and night. The laying hens are fed twice a day, high protein, high energy and low calcium feed in the morning and low protein, low energy and high calcium feed in the evening, which can not only adjust the laying period, increase egg production, but also save feed.

two。 The best feeding; chickens have two feeding peaks in a day, one is 2-3 hours after sunrise, and the feed intake is 1 month 3 in the morning, when feeding at this time, the laying rate can be greatly increased. It can be seen that the feeding effect of laying hens at 9 am and 3 pm is the best.

3. Ensure the high yield of chickens; for example, the population weight of chickens does not increase normally. Even if the current egg production and feed returns are high, the potential downward trend of egg production can be corrected by increasing consumption before the decline in egg production. If feed consumption is obviously at a high level, it only means that a lot of feed consumption or at least indicates that the feed reward is low, if the feed is obviously at a low level, while the chicken population is growing again and maintains a high egg production, it can be maintained and can make a lot of money.

4. The number of eggs increased in summer, the feed intake of chickens decreased in summer, and egg production decreased or even stopped. In order to restore normal egg production, in addition to heat prevention and cooling, shearing is also an effective way to cut off the feathers of the chicken's chest, legs and left and right wings, and retain the feathers of the neck, back and tail. The shearing length is based on the principle that the chicken skin is not damaged and the coarse capillary section does not flow. Cut less in early summer and more in midsummer.

5. Add 0.3% red chilli powder, 6% sun-dried crushed alfalfa leaves or 5% pine needle powder to the diet to deepen the yolk color.

6. Store breeding eggs; when storing breeding eggs, you should make the tip of the egg upward, so that the yolk can be located in the center of the egg, prevent embryo adhesion and improve the hatching rate of breeding eggs.

7. More hatched hens; breeding eggs are short oval, one is larger, the other is smaller, inverted triangle, surface is meticulous, hatched chickens are mostly hens; breeding eggs are long-horned, difficult to distinguish between head and tail, rough surface, and most of the hatched chickens are Roosters.

8. Distinguish between male and female; pull out the chicken wings, if you see the feathers (positive feathers) of the wings are long and short (that is, the feathers are short and long), it is the hen, and if you see that all the feathers are basically the same length, it is the rooster, with an accuracy of more than 90%.

9. To prevent chicken plague; when the chicken grows to 10-14 days old, the chicken plague IN vaccine is used for nasal drip, and the inactivated chicken plague vaccine (sold at local veterinary stations) is injected intramuscularly. At the age of 70 days, the chicken plague I vaccine was injected intramuscularly, and at the age of 120 days, the chicken plague I vaccine was injected again, and at the same time, the inactivated chicken plague vaccine was injected intramuscularly once, the protection rate could reach 100%.
