How Many Eggs Do Laying Hens Usually Lay a Day and High-Yield Farming Techniques

Laying hens are chickens raised specifically to lay eggs for egg supply, different from meat chickens; eggs are the main source of income in raising laying hens.So how many eggs can generally farmed laying hens lay a day? How to raise them for high yield? What are the farming techniques?

How many eggs can generally farmed laying hens lay a day?

Farmed laying hens generally have a cycle of about 500 days, after which they are either culled or enter molting, with egg production of around 300 eggs.

1. The laying cycle of laying hens is somewhat related to feeding management. Under normal feeding management, brown-shell laying hens generally start laying at 150 days (white-shell laying hens at about 130 days), reach peak production at about 200 days (white-shell laying hens at about 180 days), the peak lasts about 200 days, then the laying rate gradually declines. When feed input equals egg income and there is no profit to be made, they can be culled or forced to molt. The entire production cycle is about 500 days.

2. The number of eggs laid in one production cycle of laying hens is related to the breed; superior breeds have high egg production, while local mixed breeds have low egg production. It is also closely related to feeding management and disease; diseased laying hens may even have no farming value.

How to raise laying hens for high yield? What are the farming techniques?

1. Saving feed in chicken raising: The yolk and albumen of eggs are formed during the day, while the eggshell is formed in the afternoon and at night. For laying hens, feed twice a day - in the morning give high-protein, high-energy, low-calcium feed, and in the evening give low-protein, low-energy, high-calcium feed. This not only regulates the laying period and increases egg production, but also saves feed.

2. Optimal feeding: Chickens have two feeding peaks in a day. One is 2-3 hours after sunrise, when feed intake in the morning is 1/3; feeding at this time can greatly increase the laying rate. It can be seen that feeding laying hens twice, at 9 AM and 3 PM, gives the best results.

3. Maintaining high yield in chickens: If the flock's body weight is not increasing normally. Even if current egg production and feed conversion are both high, there is a potential downward trend in laying. Before egg production declines, the weight problem can be corrected by increasing consumption. If feed consumption is already clearly at a high level, that only means much feed is being consumed, or at least indicates low feed conversion. If feed is clearly at a low level, while the flock's body weight is still increasing normally and high egg production is maintained, then it can be maintained and can earn big money.

4. Increasing egg production in summer: In summer, chickens' feed intake decreases, egg production drops or even stops. To restore normal egg production, besides heat prevention and cooling measures, trimming feathers for chickens is also an effective method, that is, trimming the feathers on the chest, legs and both wings, while keeping the feathers on the neck, back and tail. The trimming length should be based on the principle of not damaging the chicken skin and no fluid flowing from the cut surface of thick feather shafts. Trim less in early summer and more in midsummer.

5. Deepening egg color: Adding 0.3% red chili powder, 6% sun-dried and crushed alfalfa leaves or 5% pine needle powder to the daily ration can all deepen the yolk color;

6. Storing hatching eggs: When storing hatching eggs, the pointed end of the egg should face upward, which keeps the yolk at the center of the egg, prevents embryo adhesion, and improves the hatchability of hatching eggs.

7. Hatching more hens: Hatching eggs that are short oval-shaped, with one end larger and one end smaller, forming an inverted triangle, and with a fine surface, mostly hatch into hens; hatching eggs that are long and angular-round, with head and tail hard to distinguish, and with a rough surface, mostly hatch into roosters.

8. Distinguishing male from female chicks: Spread out a chick's wings. If you see the wing feathers (primary feathers) with one long and one short (that is, alternating long and short feathers), it is a hen; if you see that all feathers are basically the same length, it is a rooster. The accuracy rate is over 90%.

9. Preventing chicken plague: When chicks grow to 10-14 days of age, use chicken plague IN strain vaccine for nasal drops, and at the same time use inactivated chicken plague vaccine (available at local veterinary stations) 0.3 ml for intramuscular injection. At 70 days of age, inject chicken plague I strain vaccine intramuscularly; at 120 days of age, inject chicken plague I vaccine again, and at the same time inject 1 ml of inactivated chicken plague vaccine intramuscularly once. The protection rate can reach 100%
