Nutritional needs at the peak of egg production

The body weight gains faster before 40 weeks of age, and the average daily weight gain of 24 to 40 weeks is 2-4 grams; thereafter, the weight gain rate is relatively balanced and increases slightly. If the weight is reduced during the peak period of egg production, it means that the reserve of the laying hens is used excessively, which may cause the egg production rate to decline and the egg production peak to end prematurely.

The daily intake of nutrients for hens is mainly used for weight gain, egg production expenditures, basal metabolism, and breeding needs. Therefore, when designing feed formulas, it is necessary to follow the hen's daily energy, crude protein, amino acid, calcium, phosphorus, etc. Need to calculate exact nutritional standards. When adjusting the nutrient concentration, it should be based on changes in the egg production stage and changes in feed intake. The key is to grasp the changes in the content of energy and protein. At the same time, we must also ensure the supply of calcium, phosphorus and various vitamins.
