Prevention of chicken common poisoning
First, salt poisoning
The most common cause of salt poisoning in chickens is the high salt content of dried fish or fishmeal used in the ingredients. The clinical symptoms vary according to the amount of salt intake and the length of time. Symptoms are mild, drinking water increases, feces are thin or mixed with water. In severe cases, loss of appetite, thirst for desire, endless drinking, swollen cysts, mucus flow in mouth and nose, diarrhea, dyspnea, and finally failure.
Prevention: Immediately stop the feeding of feeds containing excessive salt in diseased chickens, change other feeds, and provide sufficient fresh drinking water. Usually, the dried fish or fishmeal used in the ingredients must be measured for its salt content. The high salt content should be added less, and the low salt content can be appropriately increased, but the total salt content in the feed should be 0.25% to 0.3%. Not more than 0.5%.
Second, terrin poisoning
Furazolidone, also known as furazolidone, is a commonly used drug to prevent chicken caecal hepatitis, salmonellosis, and coccidiosis. The concentration of styribarin is 0.01% to 0.02%, and the treatment is doubled, up to a maximum of 0.06%. The amount of prevention when drinking water is 0.01%, and the treatment amount is 0.02%. Poisoning can occur if the medicine is taken in excess or the ingredients are not uniform or continuously for more than 10 days. Symptoms are mental depression, loose feathers, loss of appetite or waste, some touching the ground with a sharp tip, some chickens, such as foreign body stuck in the throat, shaking their heads from time to time, and some turning around, convulsions, and finally coma and death.
Prevention: Intoxication was immediately stopped and fed with Triazolam. As soon as possible, the chickens were given 0.1% sodium bicarbonate water or 5% glucose water. In severe cases, 10% glucose water or replenishment was given via oral drip. The usual medication must be strictly dose standards and medication time, continuous medication time up to no more than 1 week, must be mixed when adding drugs.
Third, rapeseed cake poisoning
The harmful component of rapeseed cake is mainly glucosinolate, which can decompose to produce a variety of toxic substances, in addition to sultacid and tannin. The ratio of common rapeseed cake in feed is 8% for laying hens and 10% for broilers in later stages can cause poisoning. The symptoms are initially reduced in intake, different abnormalities such as dry, thin, and bloody stools, slow growth, decreased egg production, increased soft eggs, and decreased hatching rate.
Prevention: Poisoning was immediately stopped and the feed containing rapeseed cake was immediately stopped, and supplement 14 was added to drinking water. In the usual ingredients, rapeseed cakes are not used in laying hens under 6 weeks of age and broilers under 4 weeks of age. After that, the proportion of rapeseed cakes in feed shall not exceed 5%.
Fourth, aflatoxin poisoning
Chicken feed has a variety of molds and toxins due to moisture, heat and moldy deterioration, the most important of which is Aspergillus flavus and its toxins. Chickens that eat these deteriorating feeds can cause poisoning. The symptoms are apathetic, loss of appetite, anemia, blood discharge, excrement, and some legs are gradually unable to stand, laying hens are stunted, postponed production, low egg production, and extreme weight loss.
Prevention: Poisoning was immediately stopped and fed with degenerate feed. Quick drinking or glucose was added to the drinking water, and the virus was used to kill the disinfectant and the sink. Usually feed should be stored in a cool, dry place, the amount of storage to meet the amount of 1 week is appropriate, not a large number of long-term storage in order to avoid mildew.
