The Action Mechanism of Light in Layer Production

The Action Mechanism of Light in Layer Production

 

The intensity, duration, and color of visible light can all affect the reproductive function of chickens, which in turn has a significant impact on the reproductive system development, laying time, egg laying maintenance time, egg weight, and other production performance of laying hens. The main principle is that visible light stimulates the chicken optic nerve and hypothalamus to make the hypothalamus secrete Gonadotropin-releasing hormone, which acts on the pituitary gland and causes the secretion of follicle stimulating hormone and ovulatory hormone. Follicle stimulating hormone stimulates follicular development and maturation, forming estrogen within the follicles. Estrogen and ovulation hormones jointly affect the production performance of laying hens through the bloodstream.

 

The Effect of Different Colors of Light on the Production Performance of Laying Hens

 

Research has shown that different colors of light have different effects on the production performance of laying hens. In production practice, it is best to choose warm colored light (mainly yellow, orange, and red).

 

Red light: it plays a role in enhancing Sexual maturity of chickens, improving egg weight, promoting stability and reducing fertilization rate of cocks.

 

Blue light: it plays a role in promoting chicken growth, delaying Sexual maturity, and improving the fertilization rate of cocks.

 

Orange light: it plays a role in enhancing Sexual maturity of chickens and improving egg weight.

 

Yellow light: it plays a role in enhancing Sexual maturity of chickens, increasing egg weight and reducing egg production.

 

Green light: it plays a role in promoting chicken growth, delaying Sexual maturity, and improving the fertilization rate of cocks.

 

Light is an important factor affecting chicken growth, and it is equally important as water and feed. Appropriate lighting can stimulate the secretion of sex hormones in hens, enhance the activity of the ovaries and fallopian tubes, accelerate the formation and excretion of eggs, and the development of the fallopian tubes, thereby improving the production capacity of hens. The summary of lighting knowledge for egg chicken feed brands is as follows:

 

Light intensity

 

If the light is too strong, the chicken will be agitated, resulting in pecking addiction, anal prolapse and Neuroticism. If the lighting of laying hens suddenly increases, it will lead to a decrease in eggshell quality, an increase in damaged and deformed eggs, and an increase in sudden death rate.

Illumination at each stage

 

1. Brood period: Both chicks and adult chickens are in the growth period. The light in this stage should promote the healthy growth of chicks with a high survival rate, but it should prevent hens from reaching Sexual maturity prematurely. Chickens can grow well under low intensity weak light, but in order to enable them to eat and drink more as soon as possible, the daily light duration for the first week can reach 12 hours, and the light intensity can be higher. As the age increases, the light intensity gradually weakens. This not only saves electricity and makes the chicks quieter, but also prevents the occurrence of pecking habits.

 

2. Maturity period: The light duration should be short, not gradually extended, and the intensity should be weak. The main purpose of this stage is to control growth and development and achieve Sexual maturity at an appropriate age. Early Sexual maturity means not only that the egg weight is small at the start of production, but also that the production stops soon after the start of production due to insufficient body maturity, and then the stable and high yield cannot be achieved.

 

3. Egg laying period: Enable the hen to start laying in a timely manner and reach its peak, fully tapping into its egg laying potential. Therefore, the lighting time should be long and should not be gradually shortened. The intensity of light cannot be reduced. Egg laying is generally done with increasing or constant light, but no less than 16 hours of light per day. The laying period is very sensitive to light and can only be increased or maintained, not reduced.
