Chicken breeding technology essential knowledge

Necessary knowledge of chicken breeding technology

          The aquaculture industry involves many fields and will encounter various problems in production. Master the necessary knowledge of breeding, can find out the real reason through analysis and judgment in the complicated problems, and make the correct countermeasures.

1. Special digestive system

        Chickens have no teeth and do not eat food. The intestinal tract is short and small. The crop is used to store food, the glandular stomach secretes gastric juice, and the muscular stomach digests food. This special digestive system causes chickens to consume less feed and digest faster. Therefore, it is necessary to feed less frequently when feeding, especially for chicks.

2. No thoracic diaphragm

        Unlike other animals, there is no diaphragm between the respiratory, digestive, and urinary systems of chickens, so it is easy to form cross-infection when the disease occurs. This requires that the treatment of coliform bacteria should be considered when treating respiratory diseases, and the treatment of the respiratory tract should be considered when treating coliform bacteria.

Three, there is a bursa of fabric

         The bursa of Fabricius is a special organ tube of chickens, which may cause a bursa epidemic, so necessary bursal immunization is necessary.

 4. Have memory, ability to recognize position, imitate, and good biological clock rhythm

          This requires regularity in daily management. Such as: feed regularly, switch lights regularly, do not change the environment arbitrarily, otherwise it will cause stress, reduce immunity, and induce disease.

5. Being timid, afraid of shock, noise, and strong light, sensitive to red, but not blue

         Therefore, do not allow strangers to enter the chicken house, avoid glass reflections, avoid red work clothes, preferably blue, and use blue light bulbs when exiting the grid.

  6. Underdeveloped sense of taste, average sense of smell, poor drug resistance

         Based on these characteristics, the drug should be used in an appropriate amount. Overdose can easily cause drug poisoning. In the actual administration, the total amount of medicine for a course of treatment should be fed in the proportion of more, medium and less, so that the medicine in the chicken body will be balanced. For example, the total amount of medicine for three days is 15 bottles, and it should be fed in a ratio of 6, 5, and 4 instead of 5, 5, and 5.

Seven, special heat dissipation method

         Chickens have thin skin and less subcutaneous fat, which is conducive to the dissipation of heat in the body. It can form a stable air insulation layer around the chickens. The feathers of the chickens are flat or erected to change the degree of insulation, so adult chickens can tolerate lower levels. temperature. Chickens don’t have sweat glands, and their skin evaporates to release only limited water, so they mainly rely on breathing to evaporate heat. In this way, the higher the temperature, the higher the chicken’s body temperature and the faster the respiration, so it is difficult for grown-up chickens to tolerate high temperatures. At 32°C, the number of deaths will increase significantly, and at 38°C, chickens will die from heat exhaustion. Therefore, when raising in the hot season, the maximum temperature in the chicken house should not exceed 32°C. When it is released, keep it warm in winter and prevent heatstroke in summer.
