Six common causes of high mortality of chicks

In the whole process of breeding, the first step is brooding. The resistance of chicks is poor, so it is necessary to do a good job in management methods in various fields and reasonably improve the survival rate of brooding. In the whole process of brooding, these six reasons are very easy to lead to the death of chicks. The following will actually give you a detailed introduction to which six reasons.

1. Disinfection and sterilization

Before entering the chick, the chicken shed is not completely cleaned, not fumigated, only sprayed with disinfectant once or twice, to promote the microbial strains to have for a long time, chicks susceptible to Escherichia coli, streptococcus and so on lead to death.

2. Chicken shed temperature

Before entering the chick, the pre-temperature of the barn is insufficient, which leads to the chicks gathering and extruding to death; when the temperature is too high, the chicks have high suction and compressive strength, and lack of water; when the temperature is high and low, the chicks are easy to catch cold, leading to diarrhea and drying, all of which endanger the digestion and absorption of yolk.

3. The natural environment of the chicken shed

When raising chicks in spring and winter, only thinking about thermal insulation, ignoring appropriate ventilation, maintaining the barn gas fresh, resulting in nitrogen dioxide, carbon monoxide content is too high, light respiratory symptoms, more serious poisoning.

4. Relative density of feeding

Most of the farms have the condition of overfeeding, which makes the density of chickens high, which makes it inconvenient to observe and check the situation of chickens, uneven growth and development, poor gas, and rapid spread of diseases, resulting in a higher fatality rate.

5. Misuse of therapeutic drugs

After entering the chick, it is not to use special medicine for chicks to prevent white dysentery, but to follow others' words and use up a lot of antimicrobials, even those marked with 200KG water, which aggravates the burden of liver and kidney and causes a large number of chicks to die.

6. Immunity is not immediate

Chickens are very prone to respiratory symptoms. Some chicken farmers stop taking medicine as soon as they hear that the respiratory sound of chickens is too strong, delaying Newcastle disease, bursa of Fabricius and other key infectious diseases, leading to infectious diseases. In addition, when they enter the chicks in autumn, they do not attach great importance to the early prevention of fowlpox vaccine until they are inoculated with fowlpox vaccine for 60 or 120 days, resulting in more serious fowlpox disease, especially throat fowlpox.

Chicks in the whole process of growth and development, these aspects should be paid attention to, in order to reasonably ensure the survival rate of chicks, everyone in the brooding of these many levels must be guaranteed, with regard to chicks, do you have anything to fill?
