Coccidiosis and its symptoms

The disease Coccidiosis is commonly also known as Cocci. It is seen in the chickens when a microscopic parasite Cocci attaches to the inner lining of the gut. As Cocci cause this disease, the disease is named after that. The chickens are exposed to the Cocci every day, and it might be possible that they develop immunity against the parasite. That’s why younger chickens are more susceptible to the disease because the older chickens have developed the resistance against the disease.

Coccidiosis can be fatal if not treated properly. For diagnosing the disease, these are the common symptoms that chickens show when they are suffering from the disease:

  • Loss of appetite
  • Dehydration
  • Diarrhoea

How is the disease caused?

Once the parasite ( Cocci) attaches to the intestine or the cecal, it starts forming a cyst where it multiplies over the time. Nine different species of Eimora protozoa cause the disease. Different strains of Cocci affect different birds and animals. Chickens might come in contact with Cocci while eating or pecking around in dirt and faeces. More the number of parasites the chickens come in contact to while eating more are the chances of developing this disease Coccidiosis.

The most common symptom noted is the loss of appetite and blood or mucus in the faeces. However, it should be kept in mind that the presence of occasional blood in the faeces might be due shedding of the digestive lining which is normal.

Treatment and Prevention of Coccidiosis

First of all, if you observe a chicken showing symptoms of Coccidiosis or is detected with the infection keep that bird away from the flock as the infected bird can cause disease in other chickens as well. Coccidiosis occurs in the more warm environment compared to the cold climate.

As the corid is mixed with water and then given to birds, it is recommended for treating as well as preventing the disease. The infected birds do not eat due to loss of their appetite, so the corid dosage is easy to give to the birds.

First, we will see that how Coccidiosis can be treated followed by its prevention.

The recommended treatment for treating the infection you can start with the dosage of corid such as it is 10mg per gallon of water for the five consecutive days.As the chickens also suffer from dehydration make sure that birds are staying hydrated.

How does Corid work?

Corid mimics the working of vitamin B1 that is Thiamin. The cocci parasite needs this vitamin for the growth and reproduction. But now as the coccidia has corid, that mimics the mechanism of the vitamin B1 the parasite suffers from the vitamin deficiency. Due to the reduction in the vitamin levels result in the starvation and killing of the parasites. Treating the infected bird for five days makes sure that the bacteria is dead. Vitamin A and Vitamin K supplements are recommended for giving it along the treatment by corid dosage.

Other treatments can also be done for treating the infected chickens such as:

  • Mix a little amount of organic apple cider vinegar in the water that you give to chickens.
  • You can also give them yoghurt with little garlic in it to help in increasing the good bacteria in their digestive tracts.
  • The moisture in the environment is the reason for the infection caused by the coccidia parasite so make sure you keep the areas dry and clean to prevent such disease.

It is rightly said that the “ prevention is better than cure” as there is a preventive measure for this disease available. The dose of Corid is given for 21 days as mentioned on the product is provided for treatment as well as prevention of Coccidiosis.
