The key breeding laying period

In the early stage of laying the eggs, the key breeding chickens will be transferred to the laying hen houses. This period is the most important time for chicken development. On the one hand, it is necessary to grow the body and increase the body weight; on the other hand, it must develop the reproductive system rapidly, in order to enter the adulthood. Prepare for the egg period. At the beginning of the egg, the egg production rate will increase day by day, and it will rise very quickly, and the egg weight will be bigger every day. In this case, if the nutrients can’t keep up, it will not only delay the development of the chicken, but also make the laying performance of the chicken not fully utilized. In other words, the maximum egg production limit is not reached, and the peak duration is also short. The broiler chickens will be fed to the laying hens in the future. The calcium in the diet will increase from 1% to 2% or 2% calcium will be added to the 2.5% broken shells to make the total calcium content of the diet. Reached 2%. During this period, the ovaries and secondary sexual characteristics (cockscomb and meat) of the chickens developed rapidly, and the feed intake increased significantly. They must be allowed to eat ad libitum to meet their nutrient requirements. At present, there are two ways to feed the laying hens: one is to determine the feed nutrient level as the egg production rate rises after the chicken is opened, that is, when the egg production rate rises by one price, The feed nutrient level only follows; the other method is to start feeding the feed at the peak of laying eggs when the egg production rate reaches 5%. The feed nutrient level is ahead of the egg production rate, that is, the prepaid feed. It is conducive to promoting the peak of laying eggs, so that the chickens can not reach the highest ability to lay eggs because of insufficient feed nutrient levels.

The key to breeding in the middle of laying eggs Under normal farming conditions, the egg laying rate of 150,160-day-old flocks should reach 50%. During this period, the egg production rate rises quickly. After 3 to 4 weeks, the egg production peak can be reached. The peak period of laying eggs is the golden period of chicken laying. It is necessary to strengthen the farming process so that it can fully exert its genetic potential and achieve the ambition of laying eggs. Today’s excellent varieties of egg-laying chicken cages, under good farming conditions, more than 90% of the egg production rate can be maintained for about 18 weeks. From the physiological point of view of the chicken, after the peak period of laying eggs, feeding more quality feed can not make so many eggs. At the peak of laying eggs, all stress factors must be prevented. Except for the breeders in this chicken house, other personnel are forbidden to enter the chicken house. The dresser’s clothes must be the same color every day, and the color change of the bag is also easy to cause shock. In this period, you must not cut off the material, cut off the water, or cut off the electricity. The temperature should not be too high or too low. It should be “no noise”. Do not vaccinate during this period of time. The feed should be full price and stable, and cannot be easily changed. The laying hens at the peak of laying eggs are particularly neurotic, and disturbances will affect the laying of eggs, which will be difficult to recover, which will cause huge economic losses to the chicken farms. 3. After the laying of eggs in the late stage of laying, after a period of peak laying, with the increase of age, the egg production machine will gradually decline, and the egg production rate will gradually decline. At this time, according to the decline in the egg production rate, the amount of feed should be appropriately adjusted to reduce the amount of protein fed. It is not normal for the egg production rate to drop too fast for a while. To find the cause, win it. The University of Canada recommends that the egg production rate be less than 85%, and the protein intake per chicken per day is reduced to 16 grams; when the egg production rate is reduced to 65% to 70%, 14 grams of protein per chicken per day is fed.
