How to improve the survival rate of chicks?

In order to improve the survival rate of brooding, the environmental conditions of brooding must be provided, a comprehensive and balanced feed of nutrition, and strict implementation of epidemic prevention and disease prevention measures can reduce the number of deaths of chicks and achieve better economic benefits. In production, the following six comprehensive measures must be taken:

1. Strict immunization procedures and timely vaccination

Once the infectious disease of chickens spreads, it is difficult to control. Therefore, active immunization should be carried out in accordance with the immunization program based on the principle of prevention. The immunization program should be formulated according to the species of pathogenic microorganisms in the field or in the region. When introducing chicken seedlings, it is necessary to ask the seed supply unit for an effective immunization program. If there is no epidemic of a certain infectious disease in the local area, the vaccine should be temporarily vaccinated to avoid contamination of the area due to vaccination; if such a disease has occurred and epidemic, it is necessary to use this vaccine in time.

2. Strengthen disinfection management and timely drug prevention

The incubation room, brooding room, breeding eggs and various utensils are not disinfected strictly, so that Escherichia coli, staphylococcus, etc. invade the yolk sac through the poorly closed umbilicus to infect and cause omphalitis. Therefore, formalin fumigation is used for disinfection. . In addition, the chickens with large navels should be separated separately, carefully cared for at a room temperature of 2°C to 3°C higher than the normal chicken body temperature, and a therapeutic amount of antibacterial drugs should be added to the feed.

Pullorum is the primary cause of death of chickens. Antibacterial drugs should be added to the feed before the age of 3 weeks, and 0.2% oxytetracycline and 0.04% dithrin can be added to the feed to prevent the occurrence of pullorum. Coccidiosis is one of the leading causes of mortality during brooding. Coccidiosis should be prevented after 15 days of age, especially in a high stocking density, warm and humid environment, it must be prevented with drugs, and 30-60ppm (one millionth) of probenazine and other drugs can be added to the feed. Coccidiosis drugs should be replaced with new drugs after 1 to 2 years of use to prevent drug resistance.

3. The temperature and humidity are stable, and the ventilation is strengthened.

Low or high temperature, foul air, rapid temperature changes or the use of damp, polluted litter and moldy feed are all causes of pneumonia in young chicks. Some emphasize heat preservation and do not pay attention to ventilation, which leads to suffocation of chicks; some use high-power light bulbs to provide temperature, and the chicks are overheated to death due to excessive temperature; Therefore, the temperature is important. The temperature used in the brooding period should be flexibly controlled according to the season, climate, type of brooder, chick physique, age, etc. While maintaining the temperature of the brooding house, do not neglect ventilation, but do not Thieves and draughts. In the first 10 days of brooding, the indoor relative humidity should be maintained at 60% to 65%, and attention should be paid to moisture protection in the middle and later stages of brooding.

4. "Drinking" and eating at the right time, supplying full-price feed

For chicks raised in large numbers, due to the long transportation time or preparations such as vaccination, the "opening" time of the chicks is delayed for too long; Less water, resulting in untimely drinking water, excessive water loss from the chicken body, etc., resulting in dehydration of the chicks. Mainly manifested as weight loss, withered feet, convulsions, eye drop, and later collapse, paralysis and death. One thing for newly hatched chicks should be to drink water within 24 hours, so that they can start drinking water when they are not thirsty and promote their metabolism, so that the phenomenon of binge drinking and diarrhea and dehydration and paralysis will not occur. Chicks shipped outside should drink 5% glucose and 0.1% vitamin C solution within 3 hours of placement to enhance their physique, relieve stress and promote the discharge of harmful substances in the body.

In areas and farms where conditions permit, high-quality full-price balanced rations should be provided according to the feeding standards. If conditions are limited, a variety of feeds should be mixed and fed to complement nutrition. When selenium and vitamin E are deficient, chickens are prone to white muscle disease, and the feed produced in the soil selenium-deficient area is also deficient in selenium. Therefore, it is necessary to pay attention to adding selenium compounds to the feed.

5. Control the occurrence of vices and prevent crowding and squeezing

Serious vices mostly occur after 3 weeks of age, and common ones are anus pecking, toe pecking, and feather pecking. The main preventive measure is beak decapitation at 5 to 9 days of age. Usually, the management should be strengthened, and the stocking density should not be too large; the inorganic salts and essential amino acids should not be lacking in the compound feed; the light intensity should not be too strong, and the time should not be too long.

Chicks crowded and squeezed to death, the main reasons: the density was too high, and the room temperature suddenly dropped; the pile was tilted during transportation, and the piles were not evacuated in time during weighing or vaccination; water and feed were cut off for too long before feeding , crowded when drinking; sudden power failure or entering rodents and other factors cause fright and commotion and gather together. Therefore, the feeding amount should be determined according to the area ofthe chicken house, and sufficient feeding troughs and drinking fountains should be prepared. In the chick stage, 23 hours of light and 1 hour of dark training are required to adapt to the dark environment.

6. Prevent poisoning and death and reduce animal damage loss

When using medicine to prevent chicken diseases, the calculation of the dosage must be accurate. When adding drugs to the feed, it must be stirred evenly, and a small amount of powder should be mixed well, and then gradually expanded to the required content according to the specified proportion. Drugs that are insoluble in water should not be administered in drinking water, so as not to precipitate the drug at the bottom of the drinker, causing some chicks to overdose. Separate feed and drugs; do not use moldy and spoiled feed to feed chicks; improve indoor ventilation to prevent gas poisoning.

The big animal damage to chicks is the mouse damage. Therefore, before brooding, the rodents should be eliminated uniformly; the doors and windows should be closed and blocked with nylon ropes when entering and leaving the brooding room; all holes in the room should be blocked.
