How to prevent diseases in broiler chickens?

Nowadays, as people's living standards continue to improve, the demand for broiler chickens is also increasing. Due to the high nutritional value of broiler chickens, the breeding prospects are also very broad. In the process of breeding, we farmers will inevitably encounter diseases, such as pullorum, coccidiosis, infectious bronchitis, chronic respiratory tract and other disease symptoms, which will affect the healthy growth of chickens and the benefits of farmers. So how should we prevent chicken diseases during the breeding process?

1. Introduction to the main diseases of broiler chickens

(1) Pullorum

The pathogen of pullorum is mainly Salmonella, which is more common in broiler chickens aged 1-21 days. The diseased broiler chickens will have diarrhea and excrete white watery stools. After autopsy, it is found that the liver is enlarged and yellow, and there are white necrotic nodules in the myocardium, liver, gizzard, spleen and intestines.

(2) Coccidiosis

The main hazards of coccidiosis: This disease is common in broiler chickens aged 20-50 days; when chicks are infected, they excrete bloody stools, blood clots and necrotic exudates are found in the cecum of dead chickens, and the small intestine bleeds severely.

(3) Infectious bronchitis in chickens

This disease is an acute, highly contact respiratory disease. It can occur all year round, but is more likely to occur in winter because the climate is dry, the chance of sudden weather changes increases, or the chickens are too dense, poorly ventilated, lack of vitamins and minerals, and insufficient feed supply can all lead to the disease.

Sick chickens have difficulty breathing, rales, and diarrhea; dead chickens have inflammatory lesions in the nasal cavity, trachea, and bronchus, edema in the lungs, and urate deposits.

(4) Chronic respiratory diseases in chickens

Chronic respiratory diseases are mainly caused by septicemic Mycoplasma, and are more common in broiler chickens within 4-48 days of age. Sick chickens will have wheezing sounds and swollen eyelids after the onset of the disease. Dead chickens will have thickened nasal mucosa, inflamed conjunctiva, congestion and edema in the sinuses, and cheesy exudate in the air sacs.

Common disease prevention measures for chickens

1. Treatment of coccidiosis in broiler chickens

For coccidiosis, we recommend using sulfaquinoline sodium soluble powder. It is suitable for avian coccidiosis and has the strongest effect on giant, Brucella and Eimeria acervulinae in chickens. Feed continuously for 3-5 days, and it is not recommended to exceed 5 days. It is forbidden for laying hens.

2. Treatment of infectious bronchitis in broilers

Use Bupleurum chinense combined with doxycycline hydrochloride for treatment. After mixing, let the chickens eat freely. The chickens will show improvement after 3 consecutive days of use. The chicken house management must be done well, keep ventilation, reduce stocking density, and pay attention to insulation to avoid sudden changes in temperature or cold.

3. Treatment of Chronic Respiratory Disease in Broilers

Use tylosin: administer it in drinking water at a concentration of 0.05%, use it for about 5 consecutive days, it is better absorbed in the intestine; or enrofloxacin: administer it in drinking water at a concentration of 0.05%, use it for 3-5 consecutive days and the chickens will see improvement.

Other Tips for Raising Chickens

1. It is recommended to have sufficient playgrounds outside the chicken house so that the chickens can increase exercise and resistance. Rest racks should be set up inside the chicken house; the stocking density is suitable for 5 broilers per square meter, and it is best to ensure 3-6 hours of exposure every day in winter.

2. When feeding in the cold winter, we should gradually increase the feeding frequency. We can feed in small amounts frequently to reduce feed waste and improve feed utilization. At the same time, we should build a windbreak around the chicken house and clean up the excrement in the chicken house in time to prevent excessive ammonia from causing repeated respiratory diseases in chickens.
