Anal touches the egg. Some chicken farmers are used to putting their hands into the anus of the chicken to touch the eggs. This is unscientific. Because the fingers are unhygienic, it is easy to bring the bacteria into the chicken, causing local inflammation, redness, rupture, prolapse and other symptoms.
Obesity. Obese egg hens have excessive accumulation of fat, and the egg production has dropped sharply or stopped production. It can reduce feed by 10%-15% before laying eggs, or reduce 8% to 14% of concentrate after laying eggs.
Calcium phosphorus or deficiency. Cage laying hens are prone to calcium and phosphorus deficiency, resulting in rough eggshells or soft shell eggs, and even standing unsteady and dying. Add 3% calcium powder or 5% gypsum powder to the feed, and add some charcoal ash or small sand to prevent the disease.
Nutritional bias. Laying hens are most likely to have a single nutrient and a lack of vitamins. Should pay attention to add enough vitamin E after the start of production, maintain the normal function of the reproductive organs, prevent the fallopian tube stenosis caused by rectal prolapse and other diseases; winter low temperature light, should also be supplemented with vitamin D, to prevent caged laying hens can not accept outdoor light and vitamin D Lack of disease.
The eggshell is supplemented with calcium. Eggshell is a good calcium-added feed, but it is easy to deteriorate, carry bacteria, etc., egg laying into such eggshells is easy to cause disease for poultry farming manufacturer in china.
Suddenly refueling. The new feed was used immediately, and as a result, the egg production rate did not increase, but continued to decline. The reason is that chickens have a habit of feeding the feed. If it is changed suddenly, it will affect the appetite and egg production of the chicken.
