Eggshells Thinned And Fragile

  1. Reduce environmental impact. The environmental factors that influence egg shell quality are temperature, illumination and ammonia concentration in chicken coops. In spring, when the temperature rises, the amount of food intake of chickens decreases, and the absorption rate of calcium from the intestines decreases. The high temperature makes the chickens breathe faster and release more carbon dioxide, which reduces the concentration of carbonic acid in the blood and thins the eggshells. Therefore, when the temperature rises, attention should be paid to cooling down. At the same time, the amount of calcium in feed should be increased. A certain amount of sodium bicarbonate was added in the feed to increase the concentration of carbonic acid in the blood, which was also beneficial to the improvement of egg shell quality. It is necessary to remove chicken excrement timely, strengthen ventilation of chicken coops, and reduce the content of ammonia, hydrogen sulfide and other harmful gases in the house.

2. Mineral elements should be appropriate. The absorption of calcium and phosphorus in the body is always synergistic, and the appropriate amount of phosphorus can promote the absorption of calcium. The ratio of calcium and phosphorus is (1) in the incubation and growth stages. 5 ~ 2) : when l, the absorption efficiency of calcium and phosphorus is the highest. Therefore, inorganic phosphate or animal phosphate must be added to ensure the supply of phosphorus. In addition to phosphorus element, the content of iron, magnesium, zinc and manganese in feed will affect the absorption of calcium and phosphorus, which will affect the quality of egg shell. When the content of these mineral elements is high, it will form insoluble phosphate with phosphate ions and affect the absorption of calcium. Therefore, when supplementing with trace elements, the amount should not be too large, and the hardness of drinking water should not be too high, calcium supplements should not contain more other mineral elements.

3. Timely elimination of older laying hens. Under normal feeding conditions, the uterine glands of young hens can normally secrete calcium carbonate. However, in old age, due to the accumulation of fat in the body, the uterine gland will deposit certain fat, which will affect the secretion function of the gland, so that the eggshell becomes thin and brittle. At the same time, when the egg individuals at the later stage of egg production are large, the surface area of the egg increases, which will also lead to a slight shortage of calcium supply. The egg shell becomes relatively thin and brittle, so it should be eliminated in time.

4. Timely prevention and control of disease. Under normal feeding conditions, soft shell eggs, sand eggs and so on increased, often a sign of disease. Escherichia coli disease, Newcastle disease, egg drop syndrome and infectious laryngotracheitis can cause uterine glands disorder, which affects the shell quality, at this time should be timely treatment, so as not to affect quality of eggs.
