1. To have a stable breeding environment is a major turning point in the life of a laying hen. In the first 1-3 days before the first egg is produced, the hens will explore around and choose a quiet egg production site. The amount will drop by 15% to 20%, which is a psychological stress. The reproductive system develops rapidly before and after labor, and the body weight is still growing (approximately 400-500 grams in weight); long-term light shortens the rest time, and the feeding and activity time is relatively extended. These are also very important in their physiology. As a result, the hens are bred early (usually around the age of 100 days) and transferred into the chicken house cages for rearing. In particular, broiler chickens should be transferred to laying hens as early as possible so that hens can enter the laying period as soon as possible in terms of feed, drinking water, light, density, and the surrounding environment.
2. Meet the nutritional needs of chickens (1) The growth of chickens' own weight, the increase of egg production rate and the weight of eggs, make the opening period the most important period for the hens. During this period, the feed intake of chickens gradually increased from 75 to 80 grams per day to about 110 grams, but it is still possible that nutrient absorption cannot meet the needs of the body. In order to smoothly enter the peak period of egg production and reduce the impact of negative nutrient balance that may occur during the peak period on production, the initial egg production should be started from 110 to 120 days of age; 125 to 130 days of age should be started (or the egg production rate should be reached At 5%) feed is given at the peak of the egg production to allow the hen to have sufficient nutrients and strength in the body.
(2) The hen's reproductive system develops rapidly. In the role of reproductive hormones, bone marrow is formed in the bone marrow. The bone marrow accounts for more than 70% of the total bone marrow of sexually mature hens and is used for laying chickens for laying eggs. The main source of calcium. In order to promote the formation of medullary bone and avoid the emergence of pheasants at the peak of egg production, the occurrence of fatigue syndromes in caged hens will be reduced. The calcium content in the chicken diet should be about 2.5%.
(3) If the maternity period is in summer, high-energy, high-amino acid feeds should be prepared, and fats and oils can be added to feeds if necessary. The temperature is added at 1% at 30 to 35 degrees Celsius, and 2% at 35 degrees Celsius or higher. The high fat content not only reduces the dust formed by the feed but also increases the palatability. It has a good effect on enhancing the body's quality and improving the egg rate and egg weight.
3. Regularly check the body weight to check whether the nutrition meets the needs of the chickens. You can't just look at the egg production rate. Because the hens do not have enough feed intake during the labor period, the hens will consume their own nutrients to maintain the production of eggs. , but the egg weight will be smaller. If there is insufficient nutrition, first of all, the slow growth of eggs or the laying down of eggs, followed by slow growth of growth or stop growing, eventually leading to an increase in egg production rate, or even decline. Once the egg production rate is reduced, it is difficult to fully recover even if remedial measures are taken. Therefore, the body weight should be measured every 1 to 2 weeks. Any chicken whose weight can maintain the required standards can maintain long-term high yield.
4. The correct choice of fill time The light during the production period of chickens from the bred chicken 10 hours a day, gradually extended to open 16 hours a day, so artificial light should be carried out. In order to avoid the lack of light intensity caused by peak electricity at night and the phenomenon of failure due to power failure, it is best to use morning light. The method is to turn on the feed before turning off the lights at night, turn the water and power switch off after adjusting the flow rate of the water, and turn on the water and electricity switch at 3:00 in the morning. Cold nights in winter, early in the morning chicken feed intake, exercise heat production can maintain the temperature in the chicken house; hot summer chicken appetite decreased, cool in the early morning, chicken feed intake increased nutrition. In addition, the early morning light fills until 8:00 in the morning, and the eggs are basically finished. The eggs can be sold on the same day.
