The lighting programYou need to decide the lighting program in the rearing, not in the production that “H&N Layer Breeder” parent stock are grown under is an important part of the overall management program.
There are several different lighting programs that will work with “H&N Layer Breeder” parent stock. The program that has been found to give excellent results with the most consistency is the constant day lengthYou can check easily the day length in your country in internet. program. A description of the recommended lighting programYou need to decide the lighting program in the rearing, not in the production by area is given below.

Tailoring the lighting scheme to a specific breeder flock depends on the type of housing and the hatching date.
The lighting programYou need to decide the lighting program in the rearing, not in the production for all flocks in all types of housing is the same for the first two weeks. During the first two days parent stock should be given 24 hours of lightThe light is crucial for achieving the egg size that market requieres each day or an intermittent lighting programYou need to decide the lighting program in the rearing, not in the production can be applied. The intensity should be 10 lux. On day 3, reduce the duration of the lightThe light is crucial for achieving the egg size that market requieres to 16 hours per day and decrease the intensity to 5 – 7.5 lux.
At the beginning of the third week, reduce the daily hours of lightThe light is crucial for achieving the egg size that market requieres to 10 – 12 hours. Retain this duration of lightThe light is crucial for achieving the egg size that market requieres until the breeder flock is moved to the laying house. The intensity of lightThe light is crucial for achieving the egg size that market requieres should be 5 – 7.5 lux.
In open houses, the lighting programYou need to decide the lighting program in the rearing, not in the production from 15 days of age until transfer to the laying house, depends on the hatching date. Flocks hatched between February 15 and May 15 need to be given artificial lightThe light is crucial for achieving the egg size that market requieres equal to the natural daylight on June 21. On June 21, the artificial day lengthYou can check easily the day length in your country in internet. needs to be changed to the length of the natural day at the time the flock reaches 18 (Brown Nick) / 19 (White Egg Parent Stock) weeks of age.
At 15 days of age, the artificial day lengthYou can check easily the day length in your country in internet. for flocks hatched between May 16 and February 14 needs to be set equal to the natural day lengthYou can check easily the day length in your country in internet. at 18 (Brown Nick) / 19 (White Egg Parent Stock) weeks of age. When determining the natural day lengthYou can check easily the day length in your country in internet. from sunrise and sunset tables, be sure to add one hour to include twilight at dawn and dusk. For open houses in the southern hemisphere, the above mentioned calendar dates need to be shifted accordingly (adding 6 months to any given dates).

Latitudes within 30° of the equator have nearly equal periods of daylight and darkness throughout the year and may have small seasonal variations in high ambient temperatures. Therefore, designing a lightThe light is crucial for achieving the egg size that market requieres program under such circumstances is usually problematic. Poultry men in such areas need to take the amount of natural daylight and the amount of lightThe light is crucial for achieving the egg size that market requieres needed for maximum production into account. They also need to consider adding lightThe light is crucial for achieving the egg size that market requieres during the coolest part of the night to stimulate feed consumption. The H&N lighting programYou need to decide the lighting program in the rearing, not in the production recommends for flocks placed in latitudes between 0° and 30° North or South, a combinationBased on the point of action, chose the combination that works for you. of both constant and step-down programs, regardless of the type of housing.
During the first two days parent stock should be given 24 hours of lightThe light is crucial for achieving the egg size that market requieres each day or an intermittent lighting programYou need to decide the lighting program in the rearing, not in the production should be applied. The intensity should be 10 lux. On day 3, reduce the duration of the lightThe light is crucial for achieving the egg size that market requieres to 16 hours per day and reduce the intensity to 5 – 7.5 lux.
At 15 days of age, the total day lengthYou can check easily the day length in your country in internet. needs to be adjusted to 14 hours of lightThe light is crucial for achieving the egg size that market requieres. Most of the artificial lightThe light is crucial for achieving the egg size that market requieres should be given during the early morning hours. Between 10 and 12 weeks of age, the stepdown phase of the lighting programYou need to decide the lighting program in the rearing, not in the production needs to be initiated if the natural day lengthYou can check easily the day length in your country in internet. at 18 weeks of age is less than 14 hours. The change in artificial day lengthYou can check easily the day length in your country in internet. is dependent on the natural day lengthYou can check easily the day length in your country in internet. at 18 (Brown Nick)/19 (White Egg Parent Stock) weeks of age. The objective is to reduce the total lighting hours at 10 weeks of age (14 hours) to the natural day lengthYou can check easily the day length in your country in internet. at 18 (Brown Nick)/19 (White Egg Parent Stock) weeks of age in a manner that sexual maturity will be delayed. Remember to add one hour to include twilight at dawn and dusk when determining the length of natural daylight from sunrise and sunset tables. The recommended changes are outlined in the table below and charted in the following diagrams.
Use the same break time throughout the growing period. Such a program provides additional lightThe light is crucial for achieving the egg size that market requieres during the coolest part of the day in order to stimulate feed consumption, while at the same time, providing the greater control on sexual maturity that comes from decreasing day lengthYou can check easily the day length in your country in internet..
PulletsBird 0-17 weeks grown under good lightThe light is crucial for achieving the egg size that market requieres control require a sharp increase in lightThe light is crucial for achieving the egg size that market requieres to stimulate rapid reproductive development. When the flock is 18 (Brown Nick) / 19 (White Egg Parent Stock) weeks old, the length of day needs to be increased by one hour. Additional stimulations of 60 minutes per week need to be given to bring the total hours of lightThe light is crucial for achieving the egg size that market requieres up to 16 hours. In open houses, when natural day lengthYou can check easily the day length in your country in internet. is more than 12 hours at 18 (Brown Nick) / 19 (White Egg Parent Stock) weeks of age, give a stimulation of 30 minutes per week until 16 hours of lightThe light is crucial for achieving the egg size that market requieres is reached. Due to the normal high ambient temperatures in some regions, the lights for the laying period should be set to be switched on at 3:30 a.m. and to go off at 7:30 p.m. This schedule allows for feed consumption in the coolest times of the day even during the hottest season of the year.

Good growing flock records will allow you to instantly evaluate the condition and progress of each flock. Therefore, good record keeping is a very valuable management tool. Figures for mortalityMore than a 0.1 weekly mortality, feed consumption and waterThe water is as important as the feed intake should be recorded daily and summarized weekly. Body weights and body weightOnce the hen achieves the mature body weight, they shouldn’t grow much more until end of production. uniformity percentages should also be included in the records of each flock. All results should be graphed. Use of graphs will improve analyses of flock growth and mortalityMore than a 0.1 weekly mortality trends. Notes indicating vaccinations, beak treatmentYou need to check the best type of beak treatments based on the housing conditions and the local legislation for laying hens., medication, lighting changes and other significant events should be included in your growing records. Always keep in mind that accurate cage and/or pen counts of the number of birds present in the flock are very important.
