Coccidiosis is the most prevalent and costly parasite disease for the poultry industry worldwide. It could trigger most gut health issues of concern for poultry producers. Therefore, natural alternatives to control this parasite are important.
A modeling exercise conducted by a group of experts led by Dr. Damer Blake from the British Royal Veterinary College and published last year estimated the global costs of coccidiosis in more than USD 14.05 billion at prices of 2016.
Eimeria may cause disturbances in the gut epithelium and mucosa that:
Aggravate intestinal dysbacteriosis
Impair nutrient absorption
Influence wet litter
Initiate necrotic enteritis
The coccidia control methods include:
biosecurity
chemical and ionophore coccidiostats
live non-attenuated anticoccidial vaccines,and
phytobiotic products that are becoming more popular
However, many of them may not meet this condition since the active compound is already produced by industrial chemical processes.
Many companies have adopted integrated control programs. These programs include a combination of:
>> coccidiostats
>> immunoprophylaxis
>> botanical products
>> pre and probiotics
>> improved biosecurity
>> better poultry house ventilation
>> water acidification
>> leakage-free water systems to provide a drier litter
Ionophores are natural metabolites of fungi species. Ionophores include monensin, lasalocid, salinomycin, narasin, semduramycin, or maduramicin. It is well known that some Eimeria strains have gained resistance to some of the existing ionophore coccidiostats.
However, adequate shuttle or rotation programs still allow the successful application of these products in most places.
However, in some countries, the government includes some ionophores as antibiotic growth promotants, and consequently, this may limit its application in production systems that claim to be free of antibiotics.
Chemical coccidiostats do not have known antibacterial activity and are not used in human medicine.
These characteristics make them ideal for poultry antibiotic-free production. Each chemical product has a unique way of
