Fourth, pay attention to anal mop. Some chicken farmers are accustomed to putting their hands into the chicken's anus to touch the eggs. This is unscientific. Because the fingers are not hygienic, it is easy to bring bacteria into the chicken, resulting in local inflammation, redness, rupture, prolapse and other symptoms, and even cause chicken infectious diseases.
Fifth, pay attention to lack of calcium and phosphorus. Cage-laying hens are prone to lack of calcium and phosphorus, causing rough shells or soft-shelled eggs, even standing unsteady and dying. Can add 3% calcium powder or 5% gypsum powder in the feed, add some charcoal ash or small grit at the same time to prevent the disease from happening.
Six, pay attention to nutritional bias. Laying chickens most avoid a single nutrition, vitamin deficiency. Therefore, attention should be paid to adding enough vitamin E to maintain the normal function of the reproductive organs and prevent fallopian tube stenosis caused by rectal prolapse before or after the start of production; in winter, low-temperature light, the layer should also be supplemented with vitamin D, to prevent the cage Laying chickens cannot receive outdoor light and develop vitamin D deficiency.
Seven, pay attention to body fat. Egg-fat is obese, excessive accumulation of body fat, egg production will decline sharply or even stop production. Therefore, it is possible to reduce feed by 10% to 15% before laying hens are laid, or to reduce 8% to 14% of concentrates after laying eggs, and to supplement roughage (vegetable leaves, rough pods, etc.) for prevention. Can also add 2.4% choline in the feed, feed for 10 days, to reduce the "fat" and increase egg production.
