How to make high-output and precise diet for large-scale laying hens farm
Pre-laying period means the period from the beginning to the peak of laying (21-26 weeks). During this period, the rate of laying eggs increases rapidly, with a weekly increase of 12% to 20%, while the weight of hens and eggs also increase. Hens weight gain is 4-5g per day, egg weight gain is about 1g per week.
Egg-laying rate is usually more than 85% at the peak period of laying, and more than 90% at the age of 28 weeks. Normally, the peak period of laying can be maintained for 3-4 months. During this period, the egg weight does not change much and the weight of hens increases slightly.
In the post-laying period, the laying rate decreases gradually, about 0.5% per week. The weight of eggs is relatively large and the hens weight increases. Until the age of 72 weeks, the laying rate drops to 65%-70%.
1.Stage feeding
Stage feeding is to divide the laying period into several stages according to the laying rate and week age of laying hens. Different stages use diets of different nutritional levels. On the basis of research and development of products and according to practical experience, ZhengChang Feed Science and Technology has developed a "fine feeding mode" for laying hens, which not only meets the nutritional needs, but also avoids wasting feed.
Brooding period 0-60 days
Improve the immunity of laying hens. Scientific and balanced calcium-phosphorus ratio can ensure the healthy growth of chicken bones.
Breeding period 61-110 days
Body weight and shape should reach the standard, secondary sexual characteristics of reproductive system should well develop. Adjust uniformity to more than 90.
Transition period 111 - 180 days
Rapid gonadal development lays a good foundation for the production of chickens.
Peak period 181-400 days
Producing high-quality eggs, the peak period of laying eggs lasts for a long time.
Late peak period 401 days - elimination
Maximize the production performance of laying hens. It has good egg quality, low dead and elimination rate.
2.Adjustment of feeding
1). Adjust feeding according to laying curve
Adjusting the nutritional levels of protein and other nutrients in the diet of laying hens according to the laying law. ZhengChang Technology Department can adjust the diet formula according to the nutritional level of laying hens in time.
2). Adjust feeding according to seasonal temperature change
Seasonal and environmental temperature have great influence on the feed intake and egg production level of chickens. ZhengChang Technology Department changes the intake of nutrients according to the changes of temperature between summer and winter. Adjust the diet formula in time to ensure the nutritional intake and stabilize the laying level of laying hens.
3). Adjust feeding according to the status of chicken flocks
When some management measures are taken to the chickens or when the chickens are abnormal, it is necessary to adjust the feeding. When adjusting the feed formula, ZhengChang Technology Department maintains the relative stability of the feed formula on the basis of feeding standards, and pays attention to observing the effect of the adjustment.
