Broiler chickens should not be long-term feeding of oxytetracycline as a medicine for the prevention of poultry diseases, and there are obvious effects on the prevention and treatment of intestinal bacterial infections. In addition, oxytetracycline is relatively cheap and easy to purchase. Therefore, many chicken farmers like to use it as a drug additive to feed chickens in feeds. This method has obvious short-term application effects and has few side effects. However, the long-term use of oxytetracycline feeding chickens, it is easy to damage the liver, causing chicken ascites, causing a large number of deaths, and economic losses to chicken farmers.
For two generations of chickens, it is not appropriate to raise chickens and laying hens together. All broiler chickens and laying hens should adopt the "all-in, all-out," feeding system. That is, when the previous batch of chickens arrives at the treatment, they must all be processed in time. Then thoroughly disinfect the sheds, cages and all utensils.
Cage-raised chickens should not be fed with fresh green vegetables. Free-range chickens can supply a large amount of fresh vegetables for their free intake, while cage chickens cannot. Because when adding green vegetables, they must be panned and chopped. In the process, it will inevitably cause the end of the vegetables to be contaminated with bacteria or parasite eggs. The caged chickens have a small amount of activity and a single feed intake. If the caged chickens are fed with too many fresh green vegetables, the chickens can easily cause diarrhea and even cause diarrhea. As a result, the nutrients in the food are too late to be absorbed and they are excreted. The chicken's constitution weakens and its resistance to disease decreases. Cage chickens and vegetables should be fed once a week, no more than 1/6 of the day's diet.
In the poultry house, it is not advisable to put ash in the plant. Farmers often dump ash in the poultry house. It is said that it is to ensure the poultry house is dry and absorbs moisture. In fact, this practice is unscientific. Because the poultry are not happy, the plant ash will fly everywhere and cause damage to the poultry's respiratory tract. In addition, the main component of plant ash is potassium carbonate. If it is mixed with poultry manure, it is prone to chemical reactions and produces ammonia gas. Light can increase the respiratory secretions of poultry, impede growth and development, reduce egg production; severe cases can cause throat edema in poultry, there are acute diseases such as necrotic bronchitis, pulmonary hemorrhage. Poor ventilation in poultry houses is more harmful. Therefore, the plant ash must not be used for the poultry house. It is better to use raw soil, hay or turf to mix the soil and replace it frequently to keep the poultry house clean.
