For laying hens, in the case of battery cage for layers breeding, in order to fully develop their body shape, obtain a larger egg production weight, improve the qualified rate of eggs, and obtain more benefits, the following gives you an introduction to why the hens supplement the light. What should you pay attention to in laying hens?
The effect of light on laying hens:
1, promote the role of multiple hormones in the gonads; 2, through the cycle of photoperiod, the inherent rhythm of all functions in the chicken is synchronized with the light and dark. That is to say, the effect of light on the chicken is the stimulating effect of the synchronous signal. The effect of stimulating effect is the control of the age of production and the change of egg production rate; while the effect of synchronous signal is the restriction of ovulation and egg production time.
Total illumination time: Farmers need to set the length of daily artificial illumination according to the lighting needs of different stages of the flock, the total number of hours of light per day (including natural light), and the breeding period is generally not less than 8 hours, but not more than 10 hours, the egg laying period is preferably 16 hours. Gradually increase or decrease the illumination time: no matter whether the farmers increase or decrease the number of hours of illumination when performing illumination, they cannot suddenly increase or decrease dramatically. Note that each increase should not exceed 1 hour. In addition, it should be noted that the illumination time during the breeding period can only be shortened and cannot be extended. The egg production period is reversed and can only be extended and cannot be shortened. This is an important principle and it is hoped that farmers will pay attention to it and keep it in mind.
Appropriate time to increase the light: The general feeding standard stipulates that when the hens are 18 weeks old, they can start to increase the light to promote their sexual development. However, it is more reasonable to determine whether to increase the light stimulation according to whether the body weight meets the requirements. Keep in mind that light stimuli can not be used for premature births on small hens weighing less than 1000 grams. Lighting program:
Farmers must have a fixed lighting program and light Once the procedure is confirmed, it must be strictly observed and cannot be changed at will.
Whether it is from the theoretical knowledge or the production practice can be determined, in order to ensure that the laying hen has sufficient nutrient storage before the start of production, the weight of the laying hen is slightly higher than the standard is more conducive to production. Therefore, while gradually extending the light, you should gradually increase the amount of feeding. Farmers need to pay attention to the fact that when the chicken population is poor or nutritious and the temperature is extremely low (winter),Properly control the number of hours of illumination. If you use 14 hours of light to reduce the physical consumption of the laying hens, so that they have a short rest in Poultry Equipment for Sale, the next year when the warmth, the egg production rate rebounds faster and the peak is higher
