Hen's post-lay egg management techniques
When the chicken production rate dropped from the peak to less than 80%, it was transferred to the late stage of egg production management. First, the post-lay egg nutrition adjustment The nutritional level in the diet is adjusted to meet the nutritional needs of the chicken and reduce feed wastage and feed costs. (I) Method of nutritional adjustment 1. Decrease the energy and protein levels in the diet and the crude protein intake of light layers (white shells) is reduced to 16 grams per day per bird. The crude protein intake of mid-sized layers (brown shells) was reduced to 18 grams per day per bird. 2, increase the calcium in the diet, each chicken daily intake of calcium increased to 4-4.4 grams. 3, limit the total amount of feed intake. Light laying hens (white shells) generally do not have to restrict feeding during the later period of laying. Medium-sized laying hens (brown husks) may be restricted to prevent overgrowth at the end of laying, but the maximum amount of feed restriction is 6%-7% of the feed intake. (II) Matters needing attention in nutrition adjustment 1. Adjust dietary nutrient levels in a timely manner. When the egg production rate of chickens declines, do not rush to reduce dietary nutrient levels. Instead, perform detailed analysis on the specific conditions and exclude egg production caused by abnormal factors. Do not adjust when the chickens are abnormal. In the case of diets, under normal conditions, the egg production rate at the end of the laying period should drop by 0.5%-0.6% per week. Reducing dietary nutrient levels should begin 3-4 weeks after the chicken production rate is consistently below 80%. 2, nutrition adjustment should be gradually transition. Because high-yielding layers are extremely sensitive to feed nutrient responses, the reloading process should gradually transition. Do not suddenly change it. During the refueling, the new late-stage egg-laying feed should be mixed with the original egg-laying peak material for 2-3 days, and gradually transition to feeding the late-stage egg-laying feed. 3. Pay attention to the supply form of calcium sources in the diet. The daily supply of calcium sources should be supplied at least 50% in the form of particles of 3-5 mm, which can increase the absorption rate of calcium in chickens. 4. In the hot summer season, the nutritional level of the diet should not be easily reduced, and there should be no peak period of chickens. The subsequent production performance is also not good. Second, timely removal of sick and weak chickens The purpose of keeping laying hens is to obtain eggs. If chickens no longer produce eggs, they should be removed in time to reduce feed wastage and feed costs. At the same time, some oligo-productive chickens are sick due to illness. These chickens should be promptly removed. Prevent disease from spreading. (a) Look at feathers. Egg breeder feathers are older, but not disheveled, sick chickens feathered, wiegrous chicken feathers fall off, moulting, or new feathers have been replaced in advance. (b) to see the crown, meat hanging. The crown of the laying hens, the meats are large and ruddy, the sick chickens are pale or atrophied, and the broiler chickens have shrunk. (c) Look at feces. Egg-laying hens have a lot of defecation and loose, dark brown, white uric acid deposition at the top or brown (extracted from the cecum), chickens have diarrhea and color is not normal, widow chicken droppings are harder strips. (d) to see the abdomen. Laying hens are suitable for loose belly, but they are not enlarged or reduced. There are chickens with lymphatic leukemia, hydroperitoneum, or yolk peritonitis. The abdomen expands and there may be hard fleas in the abdomen. (five) look at the anus. The laying hens are large and full of anus, moist and oval in shape. The oligo-product chicken is small and wrinkled, dry and round. Third, reduce damage and improve the product rate of eggs. The breakage of eggs brings about serious losses to layer chicken production, especially in the later period of laying. (A) The main factor that causes egg breakage in the later stage of laying is heredity. Eggshell strength is affected by genetics. Generally brown shell eggs have higher intensity than white shell eggs, and the breakage rate is low. Chickens with more egg production have higher breakage rate than those with less egg production. (b) Weekly age. After chickens are laid, the eggs will gradually increase with the age of the chicken. With the increase of the eggs, the surface area will also increase, the eggshell will become thinner, the eggshell strength will decrease, the eggs will be easily damaged, and the breakage rate will be higher than the average. . (c) Disease. The eggshell quality dropped after a period of time suffering from infectious bronchitis, egg drop syndrome, Newcastle disease and other diseases. Soft shells, thin shells and misshapen eggs increased. It is even more important to pay attention to the low level of resistance of chickens in the late stage of laying. (d) Coop equipment. When the bottom net of the cage is damaged, it is easy to scrape the broken eggs. When the angle of the rolled-up net is too large, the eggs are easy to roll out of the set egg trough. When the angle is small, the eggs cannot roll out of the basket and are easily broken by the chicken. Unreasonable installation of the cage can also cause the eggs to be eaten by the chicken. (e) Collection of eggs. Every day, the number of quail eggs is too small, and often the first-born egg and the later-produced egg collide with each other and break in the cage.
