Chicken raising is to make money. This is especially true for large-scale chicken raising. The number of chickens is inevitably use poultry cage equipment. It is not so simple to raise chickens. It is necessary to make chicken farms economically effective. Still need a lot of skills. Because there are contradictions in every work and every link, and the main contradictions are constantly changing due to factors such as environment, climate, growth period and other factors, only make timely correct judgments, grasp the direction, and correctly handle these contradictions. In order to make fewer mistakes and reduce losses.
The aquaculture industry involves many fields and encounters a variety of problems in production. Mastering the necessary common sense can find out the real cause and make correct countermeasures through analysis and judgment in complicated problems. To understand the physiological characteristics and habits of chickens on chickens, chicken skin is thin, less subcutaneous fat, is conducive to heat dissipation in the body, can form a stable air insulation layer around the chicken, chicken feathers are flattened or erected to change The degree of insulation, so the chicken can tolerate lower temperatures. Chickens have no sweat glands, and the skin can only evaporate only a limited amount of water, so it relies mainly on the evaporation of heat. Thus, the higher the temperature, the higher the body temperature of the chicken and the faster the breathing, so it is difficult for the chicken to endure the high temperature when the ambient temperature reaches At 32 ° C, the number of deaths will increase significantly, and by 38 ° C, the chicken will heat and die. Therefore, when raising in the hot season, the temperature in the house should not exceed 32 °C. When it is out of the bar, it should be kept warm in winter and heatstroke and cool down in summer.
In the chicken house, due to the breathing of the flock, the excretion of feces, the metabolism of the skin, and the scattered feed, a large amount of harmful gases are generated by the decomposition of microorganisms. If you use a stove to heat, it will also produce toxic gases such as oxycarbon. In the case of poor ventilation, these harmful gases will cause the air quality in the house to drop. When the concentration is high, it will cause harm to the flock.
Because the chicken is kept in a chicken Poultry Rearing Equipment, and the chicken is also very timid, it will produce a stress reaction. In the hot summer, if the ventilation temperature is not used to reduce the temperature inside the house to within 32 °C, the chicken will be heat stressed. A heat stress is particularly damaging to the chicken, and the number of deaths will be large. After a heat stress, the heat resistance of the chicken will be significantly improved, and then there will be heat stress, and the damage to the chicken will be appropriately reduced. Before the special high temperature comes, the chicken should be allowed to adapt to the transition after two to three days of temperature difference. This can effectively overcome heat stress. Cold stress in winter: sudden temperature changes in spring and winter or persistent low temperature will cause great damage to chickens. It often does not directly lead to death, but it can cause colds, respiratory tracts, E. coli and other diseases, which will increase the mortality rate in the later period. When feeding in spring and winter, the main reason is to keep warm in the early stage, the indoor heat is stable and the feathers grow slowly. When the amount of ventilation is increased in the later period, the temperature difference will inevitably increase, so that the chicken is likely to be cold-stressed. The principle of anti-cold stress in winter is the same as the principle of anti-heat stress. The difference is a heat resistance and a cold resistance. Cold resistance is easier than heat resistance.
