What should be paid attention to in autumn feeding of laying hens?

I. environmental regulation.

The growth and development of laying hens are affected by temperature, humidity, light, harmful gas, shock, noise, sanitation, disinfection, mosquitoes and flies. Breeder pan feeding line from GOLDENEST.

Layer chicken suitable temperature of 18 ℃ ~ 25 ℃, 20 ℃ when the best rate. When high temperature heat stress reactions, cockscomb pale, anemia, lower resistance, etc., laying rate fell by 10% ~ 20%, the average egg weight by 5% ~ 10%, and eggshell quality declining in thin shell eggs, damage, soft shell eggs, egg shell egg increases, increased mortality, and on fallopian tube, ovarian damage is irreversible. Therefore, improving the thermal stress ability and preventing heat stress is the guarantee of the economic benefit of the autumn laying hens. Autumn day and night temperature difference increasing, the cold air attacks increase gradually, will cause the temperature rolling, according to the weather changes, pay attention to keep warm at night, avoid chicken group due to catch cold catch cold cold and respiratory diseases. Poor ventilation can lead to insufficient oxygen.

Because of high temperature, the chicken water quantity is big, make chicken manure becomes very thin, easy to fermentation to produce a large amount of harmful gases such as ammonia, hydrogen sulfide and cause stress, not only make the laying hens egg production performance, and easy to cause respiratory disease chicken. Among them, ammonia gas breaks the cilia of the trachea and the inner wall, and the virus and e. coli enter the respiratory system, causing respiratory diseases.


2. Feed preparation.

There is A direct relationship between the egg production rate and the feed, especially the vitamins A, vitamin D, pantothenic acid, niacin, folic acid and choline biotin. When the temperature is high, the food intake of the egg chicken is generally small. In the general feed formula, the energy can meet its needs, and other components such as vitamins may be deficient, especially the fat-soluble vitamins. Due to the influence of heat stress, the egg chicken needs more vitamins, and the vitamins in the feed are affected by high temperature, and the damage is intensified and the content is reduced. Maize, in particular, is generally lower in vitamin content than fresh corn, and poor quality corn (such as mildew) has been listed in the fall, making it worse for the poor quality of raw materials. These factors contribute to the deficiency of fat-soluble vitamins needed for laying hens and seriously affect egg production performance. Breeder pan feeding line from GOLDENEST.


Chickens are naturally sensitive to mycotoxins, and low levels of toxin in feed can cause a large number of deaths. Mycotoxins damage the immune system of the body, reduce the immune response, and focus on the effect of the egg chicken: weakened immune system and poor immune response; Ovaries and fallopian tubes atrophy, egg production decreased, deformed eggs; Decrease in intake, decrease in production performance and lower feed pay; The hatching rate of the eggs is reduced. Mycotoxin on effects of different layers are different, in the mycotoxin already know, and the toxic effect on laying hens larger with ergot toxins, rotting horses, single-ended spore mildew toxins, corn gibberellic ketene, aflatoxin, ochre and aspergillus toxin, etc.

Because of the influence of heat stress, chicken feed intake is low, in order to keep the egg must be according to the chicken feed intake, should be appropriate to raise the level of energy in the diet and nutrition concentration, reduce the size of our diet, to compensate for the decrease of thermal stress caused by nutritional intake.
