Egg-bred chickens enter the egg-laying cycle from about 18 weeks of age, and their body weight rapidly increases, and the reproductive system develops rapidly. The follicles on the ovary grow rapidly in large numbers, and the fallopian tubes also quickly grow thicker and longer and increase in weight. Weight gain and reproductive system maturation occur simultaneously. At this time, some chickens started to lay eggs. The egg production rate of well-developed chickens reached 5% at 20 weeks of age, 50% at 22 weeks of age, and 80% at 24 weeks of age. Therefore, the various nutrients in feed for chickens during this period Both environmental conditions and external conditions are very strict.
1. Chicks (1 to 60 days) Formula: 1 corn 62%, bran 10%, bean cake 17%, fish meal 9%, bone meal 2%. 2 Corn 60%, Bran 10%, Bean cake 22%, Fishmeal 6%, Bone meal 2%.
2. Young chickens (61-120 days) Formula: 15% corn, 20% bran, 7% soybean cake, 5% cottonseed cake, 5% rapeseed cake, 5% fishmeal, 2% bone meal, 1% shellfish powder. 2) 66% corn, 18% soybean cake, 11% sunflower seed meal, 3% fish meal, 1.5% bone meal, 0.5% salt.
3. The feed formulation during the egg production period: 1 corn 56%, miscellaneous grains 10%, bran 6%, bean cake 17%, fish meal 5%, shellfish powder 3%, clear stone 3% (methionine 0.1%, salt 0.4%). 2 68% of corn, 6% of bran, 8% of soybean cake, 10% of fish meal, 2% of bone meal, and 6% of shellfish.
At the peak of egg production, the egg production is switched at the right time. In order to adapt to the increase of body weight, reproductive system growth and calcium demand, layer feeds can be started at the age of 18 weeks, and the peak feeds can be fed from the age of 20 weeks. At the same time, an additional amount of multiple vitamins is added to the material. During this period, the method of restricting feeding should be cancelled so that chickens can freely feed. Make sure there is always material in the tank during lamp turn-on.
