Prevention and treatment of ozone poisoning in farmed broilers

I. Anatomy

Severe myocardial congestion, myocardial degeneration; dark brown, enlarged liver, with small sunken spots in some areas; severe lung bleeding, showing crimson; spleen showing reticular congestion; black band at the junction of glandular stomach and myogastric junction; duodenal congestion, lymphoid accumulation in the initial segment of ileum slightly raised, cecal tonsil bleeding slightly; trachea diffuse bleeding, bloody sputum; thymus is not abnormal; head is not abnormal.

II. Treatment measures

1. Lower the temperature control setting of the fan by one degree, lower the plastic film on the water curtain by 60 boxes of rice, so as to increase the ventilation rate.

2. The oxygen supply time of the ozone machine is changed to supply oxygen once an hour, 10 minutes each time.

3, oral glucose 5% concentration, double the amount of vitamin c, free drinking water at night, 4 hours a day for two days. Each shed with 2 jin of licorice + 4 jin of mung beans, fried in water, mixed with 1500 jin of water, free drinking water in the afternoon for 2 days.

4. Traditional Chinese medicine: Scutellaria baicalensis Georgi 2000g, Forsythia suspensa 1500g, Schizonepeta tenuifolia 1200g, Fangfeng 900g, Rhizoma Atractylodes 1000 g, peppermint 1000 g, Ma Bo 1000 g, shoot dry 800g, borneol 200g, Qingdai 200g, licorice 600g. According to the calculation of 2 grams per chicken, after crushing, soak in boiling water for 30 minutes, mix in the feed for 3 hours every morning, once a day for 2 days. Two days later, the whole group stopped dying and the cough basically disappeared.

Analysis: ozone used in the chicken house can play the role of disinfection, oxygen supply, promoting growth and so on, but it is a toxic gas, so it should be noted that the intermittent time of its supply should not be less than 50 minutes when supplying ozone, and ventilation should be strengthened. so that excess carbon dioxide and other gases out of the chicken house. Ozone can be decomposed into oxygen in the natural environment for about 25 minutes. The supply of ozone is too frequent, resulting in too much ozone in the chicken coop can not be decomposed and can not be discharged out of the house, making or damage to the respiratory mucosal tissue.
